eth_sendRawTransaction
Submits a signed transaction to the network. On Seismic, this endpoint is extended in two ways beyond standard Ethereum.
Seismic transactions (type 0x4A)
0x4A)The endpoint accepts Seismic transaction type 0x4A in addition to all standard Ethereum transaction types. Seismic transactions include encrypted calldata and SeismicElements metadata (e.g. encryption public key, block expiry). The transaction stays encrypted in the mempool and in blocks — decryption only happens inside the TEE at execution time. See Transaction Lifecycle for the full flow.
EIP-712 typed data
The endpoint also accepts EIP-712 typed data as an alternative to RLP-encoded bytes. Instead of passing a hex-encoded raw transaction, you can pass a signed EIP-712 TypedData object directly. The node decodes the typed data, recovers the signer, and submits the transaction to the pool.
