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 v0.18.2.

Contract	Class hash	Description
Universal ECIP	0x146EE805DD0252256484A6001DC932DD940B1787C0F24E65629F4F6645F0692	A contract allowing to compute elliptic curve multi scalar multiplication for all supported curve identifiers
RiscZero Verifier	0x6099f834b8c3030bcebb08288037a1cd8a9ffa69940c1aa1496d9feff456c7	A verifier for RiscZero Groth16-wrapped proofs.
Drand Quicknet Verifier	0x151d3a953a67b58e77660c5359f2edb1784deb761ffe4d4848af774229e6f25	A contract to verify Drand signatures. Soon with timelock encryption utilities.
SP1 Groth16 Verifier	0x79b72f62c1c6aad55c0ee0ecc68132a32db268306a19c451c35191080b7b611	A verifier for SP1 Groth16-wrapped proofs.

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 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 ensure all contracts are declared before publishing packages.
