A Cryptographic Library for Smooth Blockchain uses.
Clone the repository, then type forge test. (Some troubles are solved running foundryup and forge init --force)
Run deploy.sh to deploy the code on a target chain.
The values $RPC and $CHAINID shall be set to the chain ones.
The toy private and public key shall be replaced and funded (current can be used for testnet).
The benchmarks are performed by averaging forge results over a loop of 100 tests. Be sure to avoid the use of -via-IR and set foundry.toml correctly to reproduce correct measurements.
