Support for verifier contracts #309
Description
Currently developers only have the option to deploy their own verifier contract on testnet e.g., on Sepolia. It would be helpful if Ziren provided a suite of pre-deployed verifier contracts on different EVM-compatible chains once mainnet is ready (e.g., Ethereum, Base, Arbitrum, etc) for developers to choose from. In this way, developers can just deploy the existing contract they want to use to verify their Groth16 or PLONK proof.
