@ethereumjs/common / CustomCommonOpts
Options to be used with the custom static constructor.
BaseOpts
↳ CustomCommonOpts
• Optional baseChain: string | number | bigint
The name (mainnet), id (1), or Chain enum of
a standard chain used to base the custom chain params on.
• 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.
