There is currently no way for JSON-RPC clients to discover which historical data a node can serve without probing with trial-and-error calls and interpreting opaque error messages (`pruned history unavailable`). This makes it hard to build robust tooling on top of nodes that prune their history, for example nodes started with `--history.chain postmerge` or with reduced `TransactionHistory`, `LogHistory`, or `StateHistory` windows. This PR implements `eth_capabilities` as defined in ethereum/execution-apis#755. The method takes no parameters and returns the current head plus six per-resource capability records: - `state` - `tx` - `logs` - `receipts` - `blocks` - `stateproofs` Closes #33828 |
