🏠 Home How to check if wallet is sanctioned in javascript?
Checking whether a crypto wallet address is sanctioned or not is simple. There is a npm package @smartpkg/sanctions. All you need is to specify the network in terms of chain id and the wallet address.
import { isSanctioned } from '@smartpkg/sanctions';
const walletAddress = '0x7F367cC41522cE07553e823bf3be79A889DEbe1B';
const chainId = 1;
const result = await isSanctioned(chainId, walletAddress);
console.log(result); // true
The package supports various networks:
- Ethereum (Chain ID: 1)
- Polygon (Chain ID: 137)
- BNB Smart Chain (Chain ID: 56)
- Avalanche (Chain ID: 43114)
- Optimism (Chain ID: 10)
- Arbitrum (Chain ID: 42161)
