chain

• Optional chain: string

customCrypto

• Optional customCrypto: CustomCrypto

This option can be used to replace the most common crypto primitives (keccak256 hashing e.g.) within the EthereumJS ecosystem libraries with alternative implementations (e.g. more performant WASM libraries).

Note: please be aware that this is adding new dependencies for your system setup to be used for sensitive/core parts of the functionality and a choice on the libraries to add should be handled with care and be made with eventual security implications considered.
