Summary
The precompile provider incorrectly uses target_address instead of bytecode_address when looking up precompiles, causing failures when contracts invoke precompiles via DELEGATECALL.
Impact
Blocks containing transactions that DELEGATECALL to precompiles are unprovable.
The derived block hash and state root will not match the canonical chain, causing proof generation to fail.
Details
In DELEGATECALL context:
target_address: The calling contract's address (context preservation)bytecode_address: The actual precompile address being invoked
Using target_address causes the precompile lookup to fail, resulting in:
- Incorrect gas calculations
- Different execution results
- Invalid block derivation
Patches
Fix to be included in next v3.5.0 release by changing precompile lookups from inputs.target_address to inputs.bytecode_address.
