Precompiles
Some EVM cryptographic precompiles (notably RSA / modExp) aren't currently available.
However other cryptographic primitives like ecrecover, keccak256, sha256, ecadd and ecmul are supported as precompiles.
No actions are required from your side as all the calls to the precompiles are done by the compilers under the hood.
It's important to be aware that the gas costs and behaviors of these precompiles when invoked via delegatecall may differ from those on Ethereum.
