 ### Changed
 
-- Add strict validation for `eth_sendTransaction` and `eth_signTransaction` params — reject requests whose params do not match the transaction schema (extraneous top-level keys, ill-typed fields such as non-hex `to`/`data`, malformed `accessList` / `authorizationList` entries) or exceed `MAX_TRANSACTION_PARAMS_SIZE_BYTES` when serialized. Prevents downstream normalization / PPOM WASM from crashing on deeply-nested junk fields or padded payloads and silently bypassing security scans.
