Overview

deBridge uses internal chain IDs which may differ from standard EVM chain IDs for some chains. Always use these chain IDs when interacting with the deBridge API.
You can fetch the latest chain information by calling the deBridge API: https://dln.debridge.finance/v1.0/supported-chains-info

Usage Example

import { CHAIN_IDS } from './utils/chains';

// Create a bridge order from Ethereum to Polygon
const order = await createDebridgeBridgeOrder({
  srcChainId: CHAIN_IDS.Ethereum.toString(),
  dstChainId: CHAIN_IDS.Polygon.toString(),
  // ... other parameters
});

​
Important Notes

  • Lightlink (100000003) is currently suspended and not available for bridging
  • Always convert chain IDs to strings when passing them to API endpoints
  • deBridge custom chain IDs (100000000+) are different from standard EVM chain IDs
