1. What Is Transaction Broadcast
Transaction broadcast is the step where a signed transaction is sent to the network so nodes can validate it and include it in a block. It is the final action that puts a transaction in the mempool.
2. How It Works
A wallet signs a transaction locally (proving ownership) and broadcasts it to connected nodes via RPC. Nodes validate it (signature, balance, nonce) and relay it to peers, adding it to their mempools. Miners/validators then select it for inclusion. Broadcast failures (wrong nonce, insufficient funds, network issues) return errors.
3. Why It Matters
Broadcast is where users often hit problems — stuck transactions (low gas), nonce issues, or dropped relays. Understanding broadcast mechanics helps diagnose pending transactions and use alternatives like private relays for speed or MEV protection.
4. Key Facts
- Broadcast uses eth_sendRawTransaction (Ethereum)
- Gas price/nonce determine inclusion likelihood
- Private relays (Flashbots) submit directly to validators
- "Replacement" transactions (higher fee) can supersede stuck ones
