# eth\_sendTransaction - BSC

This method requires the sender account to be unlocked on the node. This method is not available on public RPC endpoints (for example GetBlock). For public RPCs, use eth\_sendRawTransaction with a locally signed transaction.

| from     | string | Yes      | Sender address    |
| to       | string | No       | Recipient address |
| gas      | string | No       | Gas limit         |
| gasPrice | string | No       | Gas price         |
| value    | string | No       | Value in wei      |
