The Core class is a TypeScript class that provides an interface for signing messages and transactions on the Ethereum blockchain. It uses the ethers library, which is a popular library for interacting with Ethereum.

You can instantiate core with :

• Mnemonic
• Passphrase
• PrivateKey

Example :

import { Core } from '@arianee/core';
Core.fromMnemonic(mnemonic);
Core.fromPassPhrase(passphrase);
Core.fromPrivateKey(privateKey);
Core.fromRandom();

The returned instance will have 4 methods (see TransactionLike):

signMessage(message:string)

signTransaction(transaction: TransactionLike))

sendTransaction(transaction: TransactionRequest) : Promise<TransactionResponse | { skipResponse: true }>

getAddress():string

Note: If you are using sendTransaction in an asynchronous context (e.g. adding the transaction to a queue instead of sending it directly), you must return { skipResponse: true } instead of a TransactionResponse so that the @arianee/* packages won't try to fetch the transaction receipt.

If you need to implement core with an external wallet (like metamask), you need to instantiate the class with 3 functions:

• signMessage is a function that behaves like the signMessage from ethers
• signTransaction is a function that behaves like the signTransaction from ethers
• getAddress is a function that returns the address of the wallet

import { Core } from '@arianee/core';
const core = new Core(signMessage, signTransaction, getAddress);
