Whether you choose REST API or SDK, integration is straightforward. Here's an example using our SDK to stake SUI.
// Sui SDK
import { Sui } from '@stakefish/sdk-sui';
// or: const { Sui } = require('@stakefish/sdk-sui');
const delegator = process.env.SUI_ADDRESS;
const privateKey = process.env.SUI_PRIVATE_KEY;
async function main() {
const sui = new Sui();
// Delegation (1 SUI = 1,000,000,000 MIST)
const tx = await sui.delegate(delegatorAddress, '1000000000');
// Sign
const signedTx = await sui.sign(privateKey, tx);
// Broadcast
const result = await sui.broadcast(signedTx);
console.log('Broadcast result:', JSON.stringify(result));
}
void main().catch(console.error);Works the same across all supported chains
