eth_sendTransaction

Sends a single transaction. The user’s smart account is the sender. Inside the Startale App this call is sponsored and the user pays no gas. In a standalone application it is not sponsored, and it cannot carry a custom paymaster. See the note under Notes.

Request

const hash = await provider.request<`0x${string}`>({
  method: 'eth_sendTransaction',
  params: [
    {
      to: '0x...',
      value: '0x38d7ea4c68000', // 0.001 ETH
      data: '0x...',             // optional
    },
  ],
})

Parameters

`0x${string}`

required

Recipient address.

`0x${string}`

Hex-encoded value in wei. Defaults to 0x0.

`0x${string}`

Hex-encoded calldata. Defaults to 0x.

`0x${string}`

The connected smart-account address. Handling differs by context:

Inside a Mini App, the host overwrites from with the smart account, so you can omit it.
In a standalone application, from is required and is not rewritten. A missing value, or one that does not match the connected account, is rejected with -32602.

Returns

0x${string}, the transaction hash.

Errors

Code	Cause
`4001`	User rejected the transaction
`4100`	Wallet not connected
`-32603`	The network fee could not be estimated, or the transaction failed to send

Notes

In a standalone application, pass the connected smart-account address as from. Only a Mini App has it rewritten for you.
Inside the Startale App, gas is sponsored by Startale.
In a standalone application, this method cannot use paymasterOptions. The paymaster travels as an EIP-5792 capability and this method carries no capabilities, so the user pays. Send through wallet_sendCalls to route through your own paymaster, even for a single call.
