Ethereum-like Transaction

A MetaMask user, who has the Waves network selected, can sign and send a transaction that invokes a dApp script or transfers a token. The binary format of such a transaction is similar to that used on the Ethereum blockchain, but the transaction is executed on the Waves blockchain. More about MetaMask support

Ethereum-like transaction is enabled by feature #17 “Ride V6, MetaMask support”.

Transaction Fee

If an Ethereum-like transaction invokes a dApp script, the minimum fee is defined as for an Invoke Script transaction.

If an Ethereum transaction transfers a token, the minimum fee is defined as for a Transfer transaction.

An Ethereum-like transaction cannot be sent from a smart account or dApp.

JSON Representation

JSON representation of an Ethereum-like transaction depends on its content.

For a dApp script invocation:

  }
}

The fields that are common to all types of transactions are described in the Transaction article.

Features of the Ethereum-like transaction JSON representation:

• sender contains Waves address base58 encoded,
• senderPublicKey is 64 bytes base58 encoded,
• bytes contains bytes of the entire Ethereum-like transaction, including the ECDSA signature, HEX encoded.
• proofs array is missing.

Binary Format

See the Ethereum-like Transaction Binary Format article.

Ride Structure

If an Ethereum-like transaction is verified by an asset script, the transaction is interpreted as TransferTransaction or InvokeScriptTransaction. See details in the Support in Ride section.
