Sui 区块链提供了一个带有函数 request_add_stake 的系统移动模块，可促进质押. 你可以使用 TypeScript 软件开发工具包调用这个函数，如下所示：

import { SuiClient, TransactionBlock } from '@mysten/sui';

// Initialize the Sui client
const client = new SuiClient({ network: 'mainnet' }); // or 'testnet', 'devnet', etc.

async function stakeSUI(validatorAddress: string, amount: number) {
  const tx = new TransactionBlock();

  // Construct the staking transaction
  tx.moveCall({
    target: '0x2::sui_system::request_add_stake',
    arguments: [validatorAddress, amount.toString()],
  });

  // Sign and execute the transaction
  const response = await client.signAndExecuteTransaction(tx);
  console.log('Stake Transaction Response:', response);
}

此代码初始化交易，将指定数量的 SUI 代币质押到给定的验证器地址. 确保 ValidatorAddress 准确无误，并且您的钱包有足够的资金用于抵押和汽油费.
