Retrieves the list of tokens supported for deposits into a specific yield strategy.

​
Import

import { fetchSupportedAssets } from "@paxoslabs/amplify-sdk";

​
Usage

const assets = await fetchSupportedAssets({
  yieldType: YieldType.CORE,
  chainId: 1, // optional, defaults to mainnet
});

​
Parameters

ParameterTypeRequiredDescription
yieldTypeYieldTypeYesYield strategy type (CORE, TREASURY, or FRONTIER)
chainIdnumberNoBlockchain network ID (defaults to 1 for mainnet)
interface FetchSupportedAssetsParams {
  /** Yield strategy type */
  yieldType: YieldType;
  /** Blockchain network ID (optional, defaults to mainnet) */
  chainId?: number;
}

​
Return Type

interface SupportedAsset {
  /** Token contract address */
  address: `0x${string}`;
  /** Token symbol (e.g., "USDC") */
  symbol: string;
  /** Token decimals (e.g., 6 for USDC) */
  decimals: number;
  /** Whether token supports EIP-2612 permit */
  supportsPermit: boolean;
}

type FetchSupportedAssetsResult = SupportedAsset[];

​
Examples

import { fetchSupportedAssets, YieldType } from "@paxoslabs/amplify-sdk";

// Fetch assets for Core yield strategy
const coreAssets = await fetchSupportedAssets({
  yieldType: YieldType.CORE,
});

console.log(`Found ${coreAssets.length} supported assets`);
coreAssets.forEach(asset => {
  console.log(`${asset.symbol}: ${asset.address}`);
});

​
Checking Permit Support

Use the supportsPermit field to determine the optimal deposit flow: 
const assets = await fetchSupportedAssets({ yieldType: YieldType.CORE });

const asset = assets.find(a => a.symbol === "USDC");
if (asset?.supportsPermit) {
  // Can use gasless permit flow
  console.log("USDC supports permit signatures");
} else {
  // Must use approval flow
  console.log("USDC requires standard approval");
}
