Moderator's answer To use a custom RPC URL instead of testnetConnection, you can use the following approach:

import { Connection, JsonRpcProvider } from '@mysten/sui.js'; const connection = new Connection({ fullnode: 'RPC_URL', }); const provider = new JsonRpcProvider(connection);

Consider migrating to the latest version of the SDK ®mysten/sui® instead of the deprecated ®mysten/sui.js®.
