## Use Cases

* **Transaction Explorer Detail**: Fetch transaction data for an explorer's transaction detail page
* **Signature Verification**: Recover the signer's address from `v`, `r`, `s` to verify authorization off-chain
* **Calldata Decoding**: Decode `input` against an ABI to display human-readable transaction actions in a wallet UI
* **Post-Submit Confirmation**: Poll after sending a transaction to detect mining (`blockNumber` becomes non-null)
