Abstract¶

This DIP reserves precompile ranges to ensure there are no conflicts with those used by the Rollup Improvement Proposal (RIP) process.

Motivation¶

As L2s begin to deploy RIPs, it is necessary to reserve an address range for use by the RIP process so as to ensure there are no conflicts between precompile addresses used by RIPs and DIPs.

Specification¶

The address range between 0x0000000000000000000000000000000000000100 and 0x00000000000000000000000000000000000001ff is reserved for use by the RIP process.

Rationale¶

By reserving an address range for RIPs, it allows the RIP process to maintain its own registry of precompiles that are not (necessarily) deployed on L1 mainnet, the DIP process is freed from having to maintain a registry of RIP precompiles while still having 255 addresses for its own use.

Backwards Compatibility¶
