​
Adding New Cryptocurrencies

Want to add a new cryptocurrency? The process involves multiple steps across different repositories.
1

Firmware Support

The cryptocurrency must first be added to trezor-firmware:
  1. Create coin definition JSON file
  2. Enable Connect support in support.json
  3. Submit pull request to firmware repo
2

Update Submodules

After firmware support is merged:
yarn update-submodules
3

Build Coins Definition

Set up Python environment and build:
python3 -m venv .venv
source .venv/bin/activate
pip install -r submodules/trezor-common/tools/requirements.txt
yarn update-coins
4

Test Integration

Test the new cryptocurrency:
  • Verify address generation
  • Test transaction signing
  • Validate on testnet first
Do NOT manually edit @trezor/connect-data/files/coins.json. It is auto-generated from firmware definitions.

​
Checking Coin Support

You can check if a coin is supported programmatically: 
import TrezorConnect from '@trezor/connect-web';

// Get all supported coins
const coins = TrezorConnect.getCoinInfo();

// Check specific coin
const btcInfo = TrezorConnect.getCoinInfo('btc');
if (btcInfo) {
  console.log('Bitcoin is supported');
  console.log('Supported features:', btcInfo);
}

// Check by network
const ethInfo = TrezorConnect.getCoinInfo('eth');
console.log('Supported EVM chains:', ethInfo.networks);
