Field	Type	Description
to	string	Target contract address (0x + 40 hex chars)
data	string	Calldata to execute (0x + hex string)
value	string	Amount in wei (e.g., "0", "1000000000000000000")
chainId	number	Target chain ID

Supported Chains

Chain	Chain ID

Prompt Examples

Submit a raw transaction:

Submit this transaction:
{
  "to": "0x1234567890abcdef1234567890abcdef12345678",
  "data": "0xa9059cbb000000000000000000000000recipient00000000000000000000000000000000000000000000000000000000000f4240",
  "value": "0",
  "chainId": 8453
}

Execute calldata on a contract:

Execute this calldata on Base:
{
  "to": "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
  "data": "0x095ea7b30000000000000000000000007a250d5630b4cf539739df2c5dacb4c659f2488dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
  "value": "0",
  "chainId": 8453
}

Send ETH with calldata:

Submit transaction with value:
{
  "to": "0xRecipientAddress...",
  "data": "0x",
  "value": "1000000000000000000",
  "chainId": 1
}

Validation Rules

Field	Validation
to	Must be 0x followed by exactly 40 hex characters
data	Must start with 0x, can be "0x" for empty calldata
value	Wei amount as string, use "0" for no value transfer
chainId	Must be a supported chain ID

Common Issues

Issue	Resolution
Unsupported chain	Use chainId 1, 137, 8453, or 130
Invalid address	Ensure 0x + 40 hex chars
Invalid calldata	Ensure proper hex encoding with 0x prefix
Transaction reverted	Check calldata encoding and contract state
Insufficient funds	Ensure wallet has enough ETH/MATIC for gas + value
