 First, navigate to the [precompiles implementation](https://github.com/OffchainLabs/@@nitroRepositorySlug=nitro@@/blob/@@nitroVersionTag=v3.7.2@@/@@nitroPathToPrecompiles=precompiles@@/) directory, `/@@nitroPathToPrecompiles=precompiles@@`, and create a new precompile implementation file called `ArbHi.go`.

+
+When selecting an address for your custom precompile, precompile addresses must not conflicts with existing Ethereum and ArbOS precompiles and avoid using addresses in reserved ranges as defined by [EIP-7587](https://eips.ethereum.org/EIPS/eip-7587). These ranges are reserved for future Rollup Improvement Proposal (RIP) upgrades and using them may cause conflicts.
