This guide explains how to install the Keplr wallet extension for your browser.

Introduction

The XRPL EVM Sidechain is a high-performance, Ethereum-compatible blockchain built using the Cosmos SDK. It integrates seamlessly with the Cosmos ecosystem via the Inter-Blockchain Communication (IBC) protocol, enabling interoperability with over 90 interconnected chains. Keplr, a leading wallet in the Cosmos ecosystem, supports XRPL EVM, allowing users to manage assets and interact with dApps across both Ethereum and Cosmos networks.

Fund Your XRPL EVM Account with Testnet XRP

To interact with the XRPL EVM Sidechain and perform cross-chain transactions, you'll need testnet XRP in your account.

Understanding XRPL EVM Address Formats

Each XRPL EVM account has two representations:

• EVM Address (0x...): Used for Ethereum-compatible interactions.
• Cosmos Address (ethm...): Used within the Cosmos ecosystem.

Both addresses correspond to the same account and share the same balance.

To convert between these addresses:

• Use the Address Translation Tool.
• Alternatively, visit the Exploreme explorer and view your account details to find the corresponding address.

Obtaining Testnet XRP

Option 1: XRPL EVM Faucet

1. Navigate to the XRPL EVM Faucet.
2. Enter your EVM Address (0x...).
3. Click "Request 90 XRP".
4. Wait for the transaction to complete; this typically takes about 2 minutes.

Note: You may need to complete certain prerequisites, such as joining the Peersyst Discord server, before requesting tokens.

Option 2: Discord Faucet

1. Join the XRPL EVM Discord Server.
2. Navigate to the #faucet channel.
3. Use the command: !faucet your_address
   • Replace your_address with either your EVM Address (0x...) or Cosmos Address (ethm...).

Example: !faucet ethm10e82dmed8mudr8ey09c0lhx6uh682ugyh44czc

Note: The Discord faucet supports both address formats and is maintained by the Enigma validator.
