An update on the last year and what is on the roadmap for the next, from the perspective of the XRP Ledger Foundation.

The founders of Heirloom, a software-as-a-service (SaaS) startup building tools that make it easy for enterprises to enter Web3, will discuss how they view the future potential of tokenized identity and credentials, while building on the XRPL with live use cases in the education and sports arenas.

A sidechain is an independent ledger with its own consensus algorithm, transaction types and rules. It acts as its own blockchain. Sidechains enable developers to launch new features and innovative applications using the foundation of XRP Ledger technology. They can also customize the XRP Ledger protocol to the needs of a specific use case or project, and be run as its own blockchain. This talk will go over what a sidechain is and what it can be used for, going in-depth on the design for XRPL bridges which allow the transfer of value between different chains—such as between the XRPL mainnet and a custom sidechain that serves a specific purpose. There will also be a demo of the sidechain CLI and other sidechain-related tooling, which make it easy for developers to spin up, test, and monitor their own sidechains.

Styngr has partnered with Ripple to launch the first audio NFTs on the XRP Ledger, delivering the first-ever recorded music NFTs at scale. This talk will outline how recorded music operates within the metaverse, the music label perspective on NFTs, and how Styngr is bringing label-backed audio NFTs to the XRPL.

It's been a jam-packed year for the Interledger technology stack, which released a new version of Web Monetization. Rafiki got a massive overhaul with the new grant system, and the Open Payments standard has evolved into actual implementation.

This session will explore how Ripple deploys applications that utilize the XRP Ledger protocol for enterprise customers.XRPL developers may have an app or service that connects to the XRPL. The talk will look at where developers run that service and how they maintain it?, as well as whether they have a continuous integration process. Other topics addressed in this session include how developers manage their infrastructure, any intricacies with hosting infrastructure in a cloud solution and connecting it to the XRPL nodes.

In this session, Peersyst will show from scratch how the team builds a simple document notarization system by taking advantage of native XRPL functionalities and turning it into the XRPStamp solution.This technological base will be used to develop the land registry system for the Colombian government that was launched in July 2022 on the XRPL mainnet. The registry aims to provide the trust, security and transparency of blockchain technology while ensuring ease of use for all citizens through access with simple digital certificates and QR codes.

You can mint NFTs using XLS-20 on the XRP Ledger, but where do you store the actual data your NFTs reference? IPFS is becoming the defacto standard for the decentralised storage of data in the world of Web3. In this talk, Matt Hamilton of Protocol Labs will look at what IPFS is, why decentralised data storage is important, and how you can use it to store your data securely. The session will also cover Filecoin and higher level services NFT.Storage and Web3.storage through an example of how to use IPFS to store XLS-20 NFT data.

This session will look at how a CBDC private ledger differs from that of the public XRP Ledger—and why this creates opportunities for developers to leverage their work, publicly. The talk will look at some of the unique requirements for developing for CBDCs and what this might mean for the broader crypto ecosystem.

The session featuring Kaj Leroy will focus on gaming, NFTs, Ripple's Creator Fund and community building on the XRPL. The team behind XPUNKS & onXRP will share their journey from being broke and issuing a token on the XRPL called the XPUNK token—without development knowledge,—to building games on the XRPL and launching a curated NFT ecosystem called onXRP. Driven by the community. the team has built one of the most active and innovative platforms on the XRPL.

XRPL Hooks is a smart contract proposal for the XRP Ledger. With Hooks Builder you can develop, test, debug and deploy your own Hooks, currently on testnet. Hooks Builder has a suite of example Hooks to choose from, while giving the developer full freedom of building their own Hooks from scratch. Hooks Builder works similarly to an IDE—with code hinting and saving plus sharing with GitHub Gists built-in. Try it out at https://hooks.xrpl.org!

This open-source demo will showcase an ERC-721 to XLS-20 NFT bridge that won a grand prize in the XRPL Hackathon: New Year, New NFTs. This presentation will involve a live presentation, technical dive and Q&A session into what is involved with bridging NFTs from EVM-based networks to the XRP Ledger with a developer introspective on considerations when creating interoperability tools such as decentralization, security, and tech stack concerns. This will also look at the tools and functions used on the XRPL to make this project work.

The European Union recently adopted comprehensive regulatory framework for the crypto industry to address crypto-assets and their service providers in the EU and provide a single licensing regime across all EU member states. Will this regulation become the global standard as we saw with the European regulation for personal data protection (GDPR)? GateHub Head of Compliance Peter Merc will explore:

1. What are the future minimal standards for issuers of stablecoins and asset-backed tokens?
2. How decentralized DeFi will remain once regulation is in full force?
3. What new legal requirements are expected for providers of non-custodial wallets?

Payments shouldn’t be complicated; they should be streamlined and straightforward. DeFi brings us closer to making financial services a fundamental human right. It provides businesses with tools that could make a difference in their economic survival. During this session, Stronghold Co-founder Sean Bennett will discuss how Stronghold uses DeFi to empower everyday businesses and regular people to take elements of the work done by banks, exchanges and insurers—such as lending, borrowing and trading—and put them into their own hands. This session will provide learnings around the benefits of DeFi and the XRP Ledger for enabling equitable and efficient payment systems, valuable tools for B2B finance, and developments and trends in high-tech payment systems.

Use-case-focused documentation not only drives developer adoption, it also accelerates the development and delivery of DApps. In this session, attendees will learn more about the RippleX documentation team’s proposal for xrpl.org, including:

1. Updating XRP Ledger documentation to be use-case focused and developer-friendly.
2. Migrating to a sustainable, viable and community-driven documentation toolchain.

Have an idea for a sidechain, but don’t know where to start? This session will go in-depth on how to build a new feature for an XRPL-based sidechain, and feature a workshop where you can think through how to build your own features into a custom blockchain. This session will be most useful for attendees who already have an idea for a feature that can be built on a sidechain. It is also recommended, but not necessary, to first attend the Sidechains 101 talk, which discusses the bridge design and walks through the tooling for working with sidechains.

The team at Zeuswap has built a working automated market maker on the XRP Ledger that allows users to provide liquidity to the overall XRPL ecosystem. This talk will share information about how to access the native XRPL DEX functions, issued currencies impacted by high-spreads, and how Zeuswap is enabling users to become liquidity providers. Join this talk for an understanding of how Zeuswap works and how it's building liquidity on the XRP Ledger while making issued currencies more tradable using Automated Market Making.

Backed by the XRPL Grants program, X-Tokenize is a command line application with several features that are prominently needed among all XRPL projects. X-Tokenize facilitates the minting, management, distribution and sale of issued currencies and NFTs on the XRPL. The demo will showcase how to use X-Tokenize and will follow a typical workflow that a new project might follow to get started, including for:

1. Issued Currencies: Create a new configuration for an issued currency, mint some tokens, set trustlines to the project with our test accounts, filter through trustlines to create a fine tuned distribution, perform a distribution and ultimately initialize liquidity on the XRPL DEX.
2. NFTs: Create a new NFT project configuration, mass deploy a collection of metadata to AWS, then automatically retrieve the URIs for the metadata and will execute NFTokenMint transactions to mint the tokens followed by creating an offer to sell the NFTokens.

The NYC/XRP meetup is the longest running and most active XRP Ledger group in the world. Events draw hundreds of attendees and have featured many notable guests from across the entire XRP Ledger ecosystem and beyond.But organizing efforts and hosting events is no easy feat, especially in the volatile landscape that is crypto. In this talk, Mo Morsi will share some tips and tricks behind running a successful local meetup and growing the community—including what does and doesn't work when it comes to the venue and catering, topic selection, hosting guests, attendee management, and more. This session is a must attend for everyone interested in growing the XRP Ledger community globally!

The XRPL decentralized exchange (DEX) currently provides liquidity exclusively by manual market making and order books. In this session, RippleX's Aanchal Malhotra will talk about a new proposal to add non-custodial automated market maker (AMM) as a native feature to the XRPL DEX.    The talk will discuss:

1. How XRPL’s inherent design features makes it particularly suitable for an AMM that could provide more liquidity at lower prices
2. The basic functionality and the key differentiating feature – the continuous auction mechanism - of the AMM proposal
3. The new ledger objects and transactors to interact with AMM and integration of AMM with the native central-limit order book based DeX.

Brought to you by XRPL Labs, this demo will uncover how to:

1. Receive and refund payments in any XRPL asset with the use of Xumm's nopCommerce plugin
2. Configure your Application Credentials and use the "Sign in with Xumm" flow or manually enter the XRPL Address where you want to receive the payments.
3. Select a token that you want to receive your payments in and optionally set payment or refund destination tags. You're now all set to receive XRPL payments in your nopCommerce webshop.

An automated market marker (AMM) is a protocol utilized in a decentralized exchange (DEX) that prices assets instead of using an order book like a traditional exchange. The XRP Ledger's DEX currently provides liquidity exclusively by manual market making and order books.

Therefore, a proposal (XLS-31) has been created to add non-custodial AMM as a native feature to the XRPL DEX in a way that provides increased returns to those who provide liquidity for the AMM and minimizes the risk of losses due to volatility. RippleX engineer Omar Khan will demo a proof-of-concept AMM-based DEX application built on the XRPL. This app will use the XRPL JavaScript library (xrpl.js) to implement it.

Internet of Value is rapidly revolutionizing and innovating the music and entertainment industry. XRPL is on the forefront of this revolution with the release of it's XLS-20 native NFT tokens, escrow smart contracts, and tokenization capabilities. Feeturre is a global collaborative creator marketplace connecting artists, producers, influencers and their representation in commerce. Feeturre has a unique rewards and awards system for creators and collectors on the platform, utilizing its XRPL token, $FEE.

In this session, XRPL Grants recipient Peerkat will present their approach to analyzing NFT data on the XRP Ledger. The talk will explore how NFT data is stored on the XRP Ledger, how to build your own reports using on-chain data, and common issues and errors. The session will take a look at how you could enhance and enrich the data by using other sources, such as social media, in order to get the most value and best insights from your reporting and data analysis.

You want to build your app, game, platform & interact with the majority of the XRPL users. You don't want to worry about key security. Good news: Xumm is not (just) a wallet. It's a platform, making it really easy for devs & users to interact.

Technology evolves organically and faster when unfettered. There however comes a tipping point when law could either enable or block further and faster development of tech. The session will apply the legal lens on the two sides of this construct.

Discussing problems and solutions with integrating XRPL with other blockchains, how to pass information, prevent double-spending and other issues. While XRPL has a lot of strengths it also lacks support for traditional smart contracts, which are required to program new transaction logic and store additional data on-chain. To work around this limitation we will discuss using additional fields of the standard XRPL transactions and also introduce the concept of intermediary smart contracts. This session is a compilation of issues and the ways we resolved them when building XRPL support in Allbridge.

The term DeFi refers to the financial applications run by smart contracts on a blockchain, typically on a permissionless or public chain. This session aims to provide a high-level overview of the Decentralized Finance landscape, including a basic intro, popular protocols and type of incentives associated with DeFi protocols. The second half of the session will focus on recent insolvent events, analyze the underlying reason and propose a few risk pillars that need to be paid attention to when interacting with DeFi protocols.

Ziggurat is a stepped tower that uses precise measurements to ensure that each foundation can support the layers above.

This session will explore the high-level goals of Project Clio, an XRP Ledger API server designed to serve as an RPC Gateway to the XRP Ledger. This enables better performance and scalability, more efficient full history storage, and the ability to add new RPC calls that aren’t supported by rippled. Nate Nichols will discuss how Clio works, why extending RPCs in Clio is easier than in rippled, and the Data API.

Recently, the concept of smart contracts arrived on the XRPL Ledger—opening the door for users to bring business logic to their financial transactions. However, it is not a smooth experience for developers, even advanced ones, to learn quickly smart contract programming and understand their limitations. Therefore, Wazen Shbair built a platform for developing visually XRPL Hooks smart contracts using a Visual Programming Language (VPL): Blockly2Hooks. This demo of the platform will show how it helps users to develop XRPL Hooks using visual drag-and-drop blocks and giving more focus on the logical design of the business logic.

Whirled Labs co-founders Ryan Molley and Pablo Padillo will demo their incubator for developing XRPL-related applications & platforms that launched after creating various platforms and applications as byproducts of recent XRPL hackathons. With the highly anticipated XLS-20d network merge, a very special and exciting NFT onboarding presentation has been prepared—for the community by the community. For this demo, members will:

1. Scan a QR code to download an xApp on their phone’s Xumm wallet.
2. Follow the app’s step-by-step guidelines to set up their wallet & claim their first NFT on a testnet.
3. View the NFTs being minted in real time with a random wallet selected for a prize.

Trustlines are a fundamental building block for a variety of XRP Ledger tokenization features, including CBDCs and fiat-collateralized stablecoins. However, as more and more token issuers embrace the XRP Ledger, the current size of each trustline will become an impediment to ledger stability and accessibility.This session gives an overview of CFTs - a proposed extension to the XRP Ledger to support a more compact fungible token (i.e., CFT) type, along with operations to enumerate, purchase, sell and hold such tokens.Unlike Trustlines, CFTs do not represent a bidirectional debt relationship, but instead can be thought of as something like a unidirectional trustline. However, CFTs can be easily used beyond debt positions, such as for tracking reputation points in an online game.Perhaps most importantly, CFTs require significantly less space than trustlines: ~40 bytes for each CFT held by a token holder, as compared to at least 234 bytes for every new trustline.

Learn about XRPhone, an invoice accounting bridge for the XRP Ledger that enables merchants using platforms like Quickbooks Online, Freshbooks and Xero to accept XRP as a payment method from their customers over the phone. XRPhone is an interactive voice response (IVR) system behaving as a virtual concierge that sends payment requests to customers' Xumm wallets, and then automatically applies payment to merchants' invoices in real time while maintaining synchronized customer account balances.

This talk explores the emerging trend around virtual communities where individuals organize around an idea or initiative and work as a collective to achieve some common goal. The demo will investigate what happens when you try to convert a digital network—oftentimes grown out of something like a Twitter hashtag where members have never met before—and attempt to mature that into a global non-profit organization through DAOs.

From DeFi to NFTs and passing through DAOs, the last few years have seen an explosion of innovations and use cases in the blockchain field. While hundreds of startups work to make these new applications reach mass adoption, bad actors are taking advantage of them. It is estimated that around $ 8.6 billion was laundered through cryptocurrencies in 2021 alone—a 30% increase from 2020. AnChain.AI has created and opened up for every developer on the XRP Ledger a free version of the BEI API (Blockchain Ecosystem Intelligence), its AI-based risk engine used to conduct wallet screening and transaction monitoring. BEI enables each project and XRPL developer to build in best-practice risk management from day 1. This session will describe how BEI works and how you can integrate it in your XRPL application in 7 simple lines of code.

Featuring Carbonland DAO, this demonstration will analyse how Carbonland DAO & Trust are using the XRP Ledger for forest conservation and carbon credits.

What options do users in low-tech environments (i.e. without smartphones or reliable connectivity) have to transact via digital assets when they do not have devices that can perform secure key management? In this talk, Julian Kanjere of the University of Cape Town will demonstrate how XRPL-based assets can be exchanged using feature phones via SMS. The solution makes use of a centralised server, tracks user balances using a unique XRP memo and makes use of an online SMS gateway. Although this wanders from core tenets of Web3 such as decentralization, this compromise may be necessary in emerging economies where access to high tech smarthones and internet are not guaranteed. There is utility in using such a service to to provide cheap and quick distribution of relief aid or social welfare, remittances, and financial inclusion.

This session hosted by Peersyst explores how to design and develop a compatible EVM sidechain and federated bridge to transfer tokens between chains. Adrià Carrera Mas will talk about how to solve the most important keys, including:

• EVM source code chosen
• Key points in the design of the network parameters
• Support and distribution of tokens on the sidechain
• Distribution and shape of accounts for bridge with federated model
• Secure management of bridge private keys and signing process
• Availability and uptime

The Center for Collaborative Economics, an XRPL Grants recipient, will give a demonstration of Give XRP—a Xumm xApp built for charitable donations on the XRPL. Certain features of the XRPL make it ideally suited to playing a key role in the new paradigm; specifically its low environmental impact, high degree of scalability via federated sidechains, and its integration with supra/governmental institutions. The session will discuss "crypto for social good" and the role DLT will play in an era where legacy systems are being rendered obsolete and the human race is searching for new paradigms.

NFTMASTER—an XRPL Grant recipient)—is the first marketplace operating on XLS-20d and processing transactions live on the devnet. The demo will showcase the new technology bring built on top of the XRP Ledger, current and future use cases of NFTs and how and where Hooks can fit into a greater vision for a software product.  This presentation brought to you by NFTMASTER will also explore:

• History of payments for software products.
• How the combination of NFTs and XRPL's payment channel can be the next stepping stone.
• How software companies can replace traditional monthly subscription models with a model where users only have to pay for what they use.

Linqto issues security tokens that represent shares in private companies on the XRP Ledger and allows qualified investors to purchase and trade these securities using native XRPL features. This session features two speakers exploring 1) how asset-backed stablecoins and other EVM-based (Ethereum Virtual Machine) tokens on the Flare/Songbird Network can be tokenized on the XRP Ledger via the Solaris bridge protocol developed by Trustline and 2) Linqto’s new alternative trading system (ATS) for private equity built on top of the XRP Ledger’s decentralized exchange.

Aesthetes aims to merge fine art and blockchain, creating the first Phygital NFTs—NFTs based on physical artworks. Users will own the 100% of a licensed digital artwork based on a physical one and the fractional ownership of that physical one, managed by Aesthetes, according to the best safety standards.Aesthetes works as a technological art curator and art gallery. Through the XRPL and the incoming XLS20d standard, we intend to let to everyone around the world to transfer the ownership of a physical artwork through few clicks and with a limited amount of money.
