ecrecover

Question

Who are the top consumers of ecrecover on mainnet?

Background

ecrecover (0x01) recovers the signer's public key from an ECDSA signature. Any contract that verifies a signature on-chain calls this. Fixed gas cost of 3,000.

Over the analysis period, ecrecover was called 15.9 million times, consuming 47.6 billion gas (25.2% of all precompile gas). It's the #2 precompile by both call count and gas.

Investigation

Gas distribution

ecrecover has a fixed gas cost, so all calls should use 3,000 gas. The chart confirms whether that holds.

Top callers

Note: The callers data below covers a smaller window (~6,000 blocks) because the self-join query needed to resolve parent contracts is too expensive to run over the full range. The gas distribution above uses the full 426K-block range.

Takeaways

• ecrecover is #2 with 15.9M calls and 47.6B gas over the analysis period
• Fixed cost of 3,000 gas per call
