Struct web3::types::TransactionParameters

pub struct TransactionParameters {
    pub nonce: Option<U256>,
    pub to: Option<Address>,
    pub gas: U256,
    pub gas_price: Option<U256>,
    pub value: U256,
    pub data: Bytes,
    pub chain_id: Option<u64>,
}

Transaction data for signing.

The Accounts::sign_transaction method will fill optional fields with sane defaults when they are omitted. Specifically the signing account's current transaction count will be used for the nonce, the estimated recommended gas price will be used for gas_price, and the current network ID will be used for the chain_id.

It is worth noting that the chain ID is not equivalent to the network ID. They happen to be the same much of the time but it is recommended to set this for signing transactions.

TransactionParameters implements Default and uses 100_000 as the default gas to use for the transaction. This is more than enough for simple transactions sending ETH between accounts but may not be enough when interacting with complex contracts. It is recommended when interacting with contracts to use Eth::estimate_gas to estimate the required gas for the transaction.
