Contract Addresses

Fibrous router contract addresses can be found below for each supported blockchain network.

Please note that router contracts have different addresses on each chain. Always verify you are using the correct contract address for the chain you are working with.

Router addresses are automatically included in API responses. You don’t need to hardcode them in your application.

Getting Router Address Programmatically

Using the API

The router address is always included in API responses:

curl -X POST "https://api.fibrous.finance/base/execute" \
  -H "Content-Type: application/json" \
  -d '{...}'

Response includes:

{
  "to": "0x274602a953847d807231d2370072f5f4e4594b44", // Router address
  "calldata": "0x...",
  "value": "0"
}

Using the SDK

import { Router as FibrousRouter } from "fibrous-router-sdk";

const fibrous = new FibrousRouter();
const chains = fibrous.supportedChains;

// Get router address for a specific chain
const baseChain = chains.find(c => c.chain_id === 8453);
console.log("Base Router:", baseChain?.router_address);
