Check USDC Blacklist Status on Solana Programmatically

Reading the status directly

There is no blacklist contract to read on Solana. The status lives in the token account itself: fetch the parsed account and check whether its state field says "frozen". That means you need the token account address, beyond the wallet address, deriving the associated token account for the USDC mint is the step most integrations miss.

Node.js (@solana/web3.js)

import { Connection, PublicKey } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const info = await connection.getParsedAccountInfo(
  new PublicKey("TokenAccountAddressToCheck")
);
const state = info.value?.data?.parsed?.info?.state;
console.log(state === "frozen");

One call instead of one integration per chain

The direct read above covers this contract only, and it returns a boolean, not the sanctions exposure or counterparty history that decides whether an address is about to be frozen. FreezeRadar's API returns all of it for every freezeable contract we track, including the 15 freeze events recorded on this one.
