# Transaction lifecycle

> Follow a Tavchain transaction from local signing and submission to execution, receipt inspection and explorer indexing.

A Tavchain transaction requests a change to chain state. Your wallet or signing library prepares it for the selected network, signs it locally and submits the signed bytes through RPC.

## Transaction stages

1. **Prepare:** select chain ID `771002`, recipient or contract, amount, nonce and fee settings.
2. **Sign:** review the details and approve with your wallet or local signer.
3. **Submit:** RPC returns a transaction hash for lookup.
4. **Execute:** an included transaction receives an execution result in a block.
5. **Inspect:** read its receipt and, optionally, view it in the explorer.

A returned transaction hash is not an execution result.

## Receipt status

| Result from `eth_getTransactionReceipt` | Meaning |
| - | - |
| `null` | This endpoint does not have a receipt at that moment. |
| `status: "0x1"` | Execution succeeded. |
| `status: "0x0"` | Execution failed; gas may still be charged and the nonce consumed. |

If submission times out, check the original hash before sending a replacement. A replacement is a deliberate nonce and fee decision.

## Read-only calls

Use `eth_call` to read contract state without submitting a transaction. A state-changing contract method needs a signed transaction and gas.

The explorer indexes chain data asynchronously. If it has not listed a transaction yet, check the RPC receipt and allow time for indexing.
