Parameters

NameTypeDescription
transactionFrameTxA signed frame transaction for the configured chain.

Returns

Promise<Hex> — the transaction hash acknowledged by the gateway.

Behavior to know

  • This action uses eth_sendFrameTransaction and the upstream toWire conversion.
  • An RPC timeout can occur after acceptance. Inspect error.context.transactionHash before trying again.
