# Transaction encoding, serialization, and signing
Transaction encoding, serialization, and signing in GenLayer is the client-side process of packaging all three transaction types into a reliable, cross-platform, efficient format and signing them with the sender's private key to verify the sender's identity.

Once prepared, the transaction is sent to the network via the `eth_sendRawTransaction` method on the RPC Server. This method performs the inverse process: it decodes and deserializes the transaction data, and then verifies the signature to ensure its authenticity. By handling all transaction types through `eth_sendRawTransaction`, GenLayer ensures that transactions are processed securely and efficiently while maintaining compatibility with Ethereum’s specification.
