Maintained Smart Contracts

We declare & maintain Smart Contracts for the community so they can be used as library calls.

Those contracts:

• Are declared both Starknet Sepolia and Mainnet.

• Those contracts are re-deployed at each release, so their code correspond to the release commit.

• The source code is always available in the main garaga repository under src/contracts

• The contracts are only declared and not deployed, their expected usage is through library syscalls., so their usage is done through their class hashes and not their contract address (which don't exist unless you deploy them yourself)

Class hashes for Garaga v1.0.1.

Contract	Class hash	Description
Universal ECIP	0x312d1dd5f967eaf6f86965e3fa7acbc9d0fbd979066a17721dd913736af2f5e	A contract allowing to compute elliptic curve multi scalar multiplication for all supported curve identifiers
RiscZero Verifier	0x1367d4ed2f58cfaaeda8cb18a8fb108d77c33b847e9beced89351adece9fd5a	A verifier for RiscZero Groth16-wrapped proofs.
Drand Quicknet Verifier	0x59d24936725776758dc34d74b254d15f74b26683018470b6357d23dcab6b4bd	A contract to verify Drand signatures. Soon with timelock encryption utilities.
SP1 Groth16 Verifier	0x4b22453df42037dd61390736454e8390910adfbbc1fa9d85613e6f375f4de22	A verifier for SP1 Groth16-wrapped proofs.

Version Compatibility: When generating calldata for these contracts, use the same Garaga SDK version as the release that declared the class hashes. For v1.0.1 contracts above, use garaga==1.0.1 (pip), garaga_rs tag v1.0.1, or garaga@1.0.1 (npm).

The SDK generates hints that are specific to each contract version. Mismatched versions will cause verification to fail.

In case you need to obtain class hashes for different versions of Garaga or declare them yourself if they do not exist, you can checkout the Garaga repo at a particular commit and run python .github/scripts/declare_maintained_contracts.py or python .github/scripts/verify_contracts.py.

At each release tag, the CI ensures all contracts are declared before publishing packages.
