The supportedProtocols function returns a list of protocols (AMMs) that are supported by Fibrous on a specific chain.

​
Function Signature

/**
  * Returns supported protocols.
  * @param chainId Chain ID.
  * @returns Mapping of AMM name -> protocol identifier.
  */
supportedProtocols(chainId: number): Promise<Record<string, ProtocolId>>;

​
Example Usage

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

const router = new FibrousRouter(); 
const chainId = router.supportedChains.find(chain => chain.chain_name == "hyperevm")?.chain_id;
if (!chainId) {
    throw new Error("Chain not supported");
}
const protocols = await router.supportedProtocols(chainId);

​
Parameters

ParameterTypeDescription
chainNamestringThe chain name to get supported protocols for (e.g., “starknet”, “scroll”, “base”)

​
Response

Returns a Promise that resolves to a Record mapping protocol names to their IDs. The response includes: 
type ProtocolId = {
  id: number;          // Protocol unique identifier
  name: string;        // Protocol name
  logoURI?: string;    // Optional protocol logo URL
};
