Snapshot X

A Cairo implementation of the Snapshot X Protocol. Refer to the documentation for more information.

Architecture

The repository is split into two different parts:

1. The Cairo files are in a Scarb package under ./starknet. (Tested with Scarb version 0.7.0)
2. The Solidity files are in a Forge package under ./ethereum. (Tested with Forge version 0.2.0)

There is also Hardhat Project in the root directory for crosschain tests.

Run Cairo Tests

Enter directory:

cd starknet

Build contracts:

scarb build

Run tests:

scarb test

Run Solidity Tests

Enter directory:

cd ethereum

Build contracts:

forge build

Run tests:

forge test

Run L1 <-> L2 tests and signature tests (typescript tests)

On a separate terminal, spin an L1 node (hardhat in this example, but could be anvil):

yarn hardhat node

Now run the tests:

yarn test-ts

Run Hardhat Tests

The Hardhat tests can be run following the procedure followed in the CI. You will need local Starknet Devnet and Ethereum devnet instances running.
