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 v1.1.0.

These hashes identify the declared v1.1.0 release contracts. Cairo 2.21.0 builds of the current source produce different hashes. Declare the current builds before you use their hashes on a network. The compiler migration does not declare contracts.

Contract	Class hash	Description
Universal ECIP	0x396d5915ecf475aab117bb25a0272b261e9e25ffe1c0ce05a51a3f77489c89e	A contract allowing to compute elliptic curve multi scalar multiplication for all supported curve identifiers
RiscZero Verifier	0x41d5e111b93acbf1afb531253e0bc64d43f90a8a99290361e851ec0c4968ab1	A verifier for RiscZero Groth16-wrapped proofs.
Drand Quicknet Verifier	0x86bf4360e082cd786bd785d3345df32777db89cd26b761f3e85b1993addfd0	A contract to verify Drand BLS signatures and store them on-chain for randomness and tlock decryption.
Drand Decrypt Quicknet	0x68e2381aa99c02aabe2a0fec18d9fb7cde6138b588dc0bcf0135a26d8ae7e22	A contract for on-chain tlock decryption using drand. Wraps the verifier via library call.
SP1 Groth16 Verifier	0x230d8612bd464979000193e4eaa73489da965a6593fb563dd2244e0b6e0443a	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 v1.1.0 contracts above, use garaga==1.1.0 (pip), garaga_rs tag v1.1.0, or garaga@1.1.0 (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.
