XRPL Grants today welcomes new judges to the selection process for Wave 2. Each judge is a respected member of their industry and among academia around the world, and includes a number of University Blockchain Research Initiative (UBRI) partners.

XRPL Grants provides funding to software developers and small teams to build inclusive standards leveraging the XRP Ledger’s open source technology and innovate in the Internet of Value. For Wave 2, XRPL Grants has expanded its panel of judges to increase the level and diversity of expertise in judging.

Sean Bennett, Co-Founder at Stronghold (USA)
Stronghold is a San Francisco-based financial technology company creating virtual payment networks that enable instant settlement and interoperability between legacy and new payment networks. At Stronghold, Sean has focused on leading the development of retail and business payment products utilizing differing payment modes, from banking layer integrations to blockchain technology.

Introducing xrpl.js

RippleX and the XRP Ledger Foundation (XRPLF) are excited to announce xrpl.js version 2.0.0, a JavaScript/TypeScript library for interacting with the XRP Ledger (XRPL). Formerly known as ripple-lib, the library was renamed to better represent its role in the XRPL ecosystem and overhauled to take advantage of modern JavaScript features.


JavaScript is one of the most widely-used programming languages, and as such has a massive community of active developers. Maintaining a JavaScript SDK enables these developers to seamlessly interact with the XRP Ledger, both in the browser and in Node.js. In addition, the JavaScript libraries (xrpl.js, ripple-binary-codec, ripple-keypairs, and ripple-address-codec) power many apps in the XRPL ecosystem, as well as packages from companies such as BitGo and Ledger.


With this release of xrpl.js, the JavaScript, Java, and Python libraries provided by the XRPLF now have parallel structures and systems. This enables developers to easily work with their preferred programming language depending on their specific needs, without having to learn an entirely new interface.

xrpl.js will continue to support all ripple-lib features, such as:

  • Serializing, signing, and submitting transactions to the XRPL
  • Retrieving information from the XRPL
  • Helpful utility functions (such as converting between drops and XRP)
  • Support for Node.js, web browsers, and React

It also introduces a number of new features, including:

  • TypeScript types for all transaction types and WebSocket requests
  • A Wallet class to make it easier to work with key pairs
  • Protections against the partial payment attack vector
  • An additional submit implementation that returns the transaction’s final outcome after validation.

In version 2.0, the library is now much more aligned with the core XRP Ledger interface. This means XRPL developers—whether new or experienced—can refer to multiple sources of documentation instead of needing to rely solely on the library-specific documentation. There are also a number of general architecture improvements, such as simplifying code, making user interfaces more intuitive (especially in relation to the core ledger), and revamping the testing structure. For a detailed list of changes, visit the changelog.

Start Building

To get started using xrpl.js, see this tutorial on xrpl.org, or check out the project repo or reference documentation.

If you already have a project that uses ripple-lib, migrate today! We have a migration guide for moving your code from ripple-lib v1.10 to xrpl.js v2.0.

We hope you enjoy building the Internet of Value, and feel welcome to reach out to the XRP Ledger developer community if you have any questions!

Announcing the First Wave of XRPL Grants

We’re excited to announce the inaugural awardees of XRPL Grants, presented by RippleX with XRPL Labs as a technical advisor. The XRPL Grants Program provides funding to independent developers building a variety of self-selected projects that leverage the XRP Ledger’s open-source technology and further accelerate the Internet of Value. The program welcomes applications from any project that builds on the XRP Ledger (XRPL) and involves some technical development.

For the first wave of the XRPL Grants Program, we invited applicants to apply with any open-source project built on the XRPL and particularly encouraged projects focused on the development of non-fungible tokens (NFTs).

In this wave, more than 100 grant proposals were submitted, and from this incredible batch of applicants, 25 grantees have been awarded nearly $2 million in total value. Among the grantees are individual developers and teams from more than 10 countries around the world. We’re also proud to award three grants to applicants from within Ripple’s University Blockchain Research Initiative.

Inaugural grantee projects tackle a wide range of problems and opportunities, including:

  • The development of NFTs for multiple industries (retail, art, music, sports, digital advertising and carbon capture)
  • Learning tools and platforms to build on and interact with the XRPL
  • Data visualization tools
  • Payment and security solutions

You can learn more about the Wave 1 grantees on the XRPL Grantees page, at XRPL-related events—including Apex: The XRPL Developer Summit—and on the RippleXDev Twitch channel.

The XRP Ledger is an open platform, and it is not necessary to apply for a grant in order to build on the XRPL. However, information regarding the application window for the next round of grants will be posted on XRPLGrants.org.
