What is Rollup.codes?
Rollup.codes is a developer reference site that catalogs how each Ethereum rollup diverges from L1, supported opcodes, precompiles, gas pricing quirks, and chain-specific behaviors. Smart contract engineers use it to vet code that needs to run identically across Arbitrum, Optimism, Base, and other rollups.
