Precompiles
Table of Contents
Overview
Precompiled contracts exist on OP-Stack chains at predefined addresses. They are similar to predeploys but are implemented as native code in the EVM as opposed to bytecode. Precompiles are used for computationally expensive operations, that would be cost prohibitive to implement in Solidity. Where possible predeploys are preferred, as precompiles must be implemented in every execution client.
OP-Stack chains contain the standard Ethereum precompiles as well as a small number of additional precompiles. The following table lists each of the additional precompiles. The system version indicates when the precompile was introduced.
| Name | Address | Introduced |

P256VERIFY
The P256VERIFY precompile performs signature verification for the secp256r1 elliptic curve. This curve has widespread
adoption. It's used by Passkeys, Apple Secure Enclave and many other systems.
It is specified as part of RIP-7212 and was added to the OP-Stack protocol in the Fjord release. The op-geth implementation is here.
