Scroll
An Ethereum ZK rollup that targets bytecode-level EVM equivalence — every Ethereum opcode is proven, so contracts deploy without modification.
Scroll is a ZK rollup whose distinguishing technical choice is bytecode-level EVM equivalence: it proves every EVM opcode rather than re-implementing the EVM in a custom ZK-friendly bytecode.
The result is the highest current compatibility with the L1 toolchain — Solidity / Vyper contracts, debuggers, and tracing tools all work unchanged. The cost is heavier proving than custom-bytecode designs, which Scroll addresses through ongoing prover optimizations.
