+# MetaMask Snap for the XRP Ledger
+
+## Overview
+
+[MetaMask](https://metamask.io/) is a gateway to blockchain apps with over 30 million users. With [Snaps](https://metamask.io/snaps/), developers can extend MetaMask to add additional features by leveraging existing APIs, such as the [XRP Ledger API](https://xrpl.org/public-api-methods.html). The Snap may also leverage JavaScript libraries such as [xrpl.js](https://github.com/XRPLF/xrpl.js) for functions like client-side key generation and transaction signing.
+
+## Details
+
+Develop, publish, and support an open source application allowing users to directly manage XRP and XRPL tokens within the MetaMask interface. The Snap should allow users to interact with XRP and XRPL tokens (on the XRP Ledger) without having to wrap tokens on Ethereum or any other blockchain.
+
+Snaps is a system that allows developers to build on the capabilities of MetaMask. It is a program that can customize and modify MetaMask's experience for end users. This Snap must add new APIs to MetaMask and add support for the XRP Ledger blockchain. See the [MetaMask Docs about Snaps for more info](https://docs.metamask.io/guide/snaps.html).
+
+As an example, the Snap would be similar to [BitcoinSnap](https://github.com/KeystoneHQ/btcsnap), but for the XRP Ledger.
+
+## Milestones
+
+| # | Description | Details | Proposed Potential Award |
+| - | ----------- | ------- | ------------------------ |
+| 1 | Create Account | Implement a Snap that securely generates and stores a new keypair and displays the associated XRPL address to the user. Make it easy for users to copy the address to share or use in other apps. | $1,000 |
+| 2 | Send XRP | Enable users to send XRP. The Snap should sign and submit the transaction to a server of the user's choice. For convenience, users can select from one of the [well-known public servers](https://xrpl.org/public-servers.html). | $2,000 |
+| 3 | Sign Anything | Enable users to sign any transaction or message. | $3,000 |
+| 4 | Sign and Submit Transaction | Enable users to sign and submit any transaction (including serialization). | $3,000 |
+| 5 | Send Requests | Enable users to submit any rippled- or Clio-supported RPC request. | $3,000 |
+| 6 | Documentation and Examples for Dapps | Enable easy [dapp](https://en.wikipedia.org/wiki/Decentralized_application) integrations: implement and document APIs for dapps to interact with the Snap, including example code. As a reference, see the [API to integrate BitcoinSnap into your dapp](https://github.com/KeystoneHQ/btcsnap/tree/master/packages/snap). | $8,000 |
+| 7 | Sample App | Build a sample app to showcase how to interact with the Dapp Integration milestone. (Milestone 6) | $5,000 |
+| 8 | Ethereum Feature Parity | Add features similar or comparable to those available when using MetaMask with Ethereum. While Snaps may not be able to use the normal MetaMask UI, you can implement support for tokens and advanced "smart transactors" by designing and building a custom UI. Feel free to propose ideas in the discussion corresponding to this milestone if you'd like feedback before building. | Up to $50,000 |
