Usage

Transfer Native Coin

const result = await Turing.evm.sendTransaction({
  chainId: 1,
  toAddress: "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
  amount: "1000000000000000000", // 1 ETH (18 decimals)
  broadcastEnabled: true,
});

if (result.txid) {
  console.log("Transaction hash:", result.txid);
}

Transfer ERC20 Token

// Transfer USDT on BSC
const result = await Turing.evm.sendTransaction({
  chainId: 56,
  contractAddress: "0x55d398326f99059fF775485246999027B3197955",
  toAddress: "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
  amount: "1000000000000000000", // 1 USDT (18 decimals)
  broadcastEnabled: true,
});

// Transfer USDC on Ethereum Mainnet
const result2 = await Turing.evm.sendTransaction({
  chainId: 1,
  contractAddress: "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48",
  toAddress: "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
  amount: "1000000", // 1 USDC (6 decimals)
  broadcastEnabled: true,
});

Without Broadcasting

const result = await Turing.evm.sendTransaction({
  chainId: 1,
  toAddress: "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
  amount: "1000000000000000000",
  broadcastEnabled: false,
});

if (result.txraw) {
  console.log("Raw transaction data:", result.txraw);
}

Parameters

interface EvmSendTransaction {
  chainId: number;            // EVM chain ID: 1 (Ethereum Mainnet) or 56 (BSC Mainnet)
  contractAddress?: string;   // ERC20 contract address; empty for native coin (ETH/BNB)
  toAddress: string;          // Recipient address
  amount: string;             // Transfer amount in the token's smallest unit
  broadcastEnabled?: boolean; // Whether to broadcast, defaults to true
}

Field	Type	Description
chainId	number	EVM chain ID — 1 for Ethereum Mainnet, 56 for BSC Mainnet
contractAddress	string	(Optional) ERC20 contract address. Omit for native coin transfers
toAddress	string	Recipient address
amount	string	Transfer amount in the token's smallest unit (e.g. wei for ETH)
broadcastEnabled	boolean	(Optional) Whether to broadcast the transaction. Defaults to true

Returns

interface EvmSendTransactionResponse {
  txid?: string;  // Transaction hash (returned on successful broadcast)
  txraw?: string; // Raw transaction data (returned when broadcastEnabled is false)
  error?: string; // Error message
}

Field	Type	Description
txid	string	Transaction hash on successful broadcast
txraw	string	Raw transaction data when broadcastEnabled is false
error	string	Error message if the transaction fails

Error Handling

const result = await Turing.evm.sendTransaction({
  chainId: 1,
  toAddress: "0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb",
  amount: "1000000000000000000",
});

if (result.error) {
  console.error("Transaction failed:", result.error);
  return;
}

console.log("Success! txid:", result.txid);
