Multichain Wallet

Generate mnemonic

This method is used to generate mnemonic. Default number of words is 12 but you can pass a number param if you want to generate more or less.

const mnemonic = multichainWallet.generateMnemonic();

// Note: Mnemonics with less than 12 words have low entropy and may be guessed by an attacker.

Transfer

This transfers the amount of tokens from the source address to the destination address It takes in an object as the parameter. It allows for the transfer of the following:

Ethereum Network

Allows for the transfer of ETH, and overriding of transactions.

// Transferring ETH from one address to another.
const transfer = await multichainWallet.transfer({
  recipientAddress: '0x2455eC6700092991Ce0782365A89d5Cd89c8Fa22',
  amount: 1,
  network: 'ethereum',
  rpcUrl: 'https://rpc.ankr.com/eth_goerli',
  privateKey:
    '0f9e5c0bee6c7d06b95204ca22dea8d7f89bb04e8527a2c59e134d185d9af8ad',
  gasPrice: '10', // Gas price is in Gwei. Leave empty to use default gas price
  data: 'Money for transportation', // Send a message
}); // NOTE - For other EVM compatible blockchains all you have to do is change the rpcUrl.

// Transferring ERC20 tokens from one address to another.
const transfer = await multichainWallet.transfer({
  recipientAddress: '0x2455eC6700092991Ce0782365A89d5Cd89c8Fa22',
  amount: 10,
  network: 'ethereum',
  rpcUrl: 'https://rpc.ankr.com/eth_goerli',
  privateKey:
    '0f9e5c0bee6c7d06b95204ca22dea8d7f89bb04e8527a2c59e134d185d9af8ad',
  gasPrice: '10', // Gas price is in Gwei. leave empty to use default gas price
  tokenAddress: '0xdac17f958d2ee523a2206206994597c13d831ec7',
}); // NOTE - For other EVM compatible blockchains all you have to do is change the rpcUrl.

The optional parameters that the object takes in are: gas price, nonce, and data.

The gas price is the price of gas in Gwei. The higher the gas price, the faster the transaction will be. It's best to use a higher gas price than the default.
The nonce is the number of transactions that have been sent from the source address and is used to ensure that the transaction is unique. The transaction is unique because the nonce is incremented each time a transaction is sent.
The data is a string parameter used to pass across a message through the transaction. Can only be used on transfer of ETH.

// Overriding pending ETH transaction.
const transfer = await multichainWallet.transfer({
  recipientAddress: '0x2455eC6700092991Ce0782365A89d5Cd89c8Fa22',
  amount: 0,

  nonce: 1, // The pending transaction nonce
  data: 'Money for feeding', // Send a message

    'mushroom deliver work spray hire nuclear wrong deputy march six midnight outside motor differ adult',
  method: 'deposit',
  payment: [{ assetId: null, amount: 1000 }],
  params: [],
});

Some of the parameters available in this function are:

The method parameter is the name of the smart contract function to be interacted with.
The method type is the type of action the method is meant to perform.
The params parameter is the parameter of the smart contract function if it requires any. It must be in the same order as the smart contract function. If the smart contract function does not require any parameters, leave it as an empty array.

The optional parameters that the object takes in are: value, contractAbi, gas price, gas limit, nonce, and private key.

The value is the amount of ETH you want to send while interacting with the function.
The contractAbi is the ABI of the smart contract. Every smart contract has an ABI that can be used to interact with the smart contract functions. If this is not specified. You can interact with all the ERC20 token standard functions by default.
The gas price is the price of gas in Gwei. The higher the gas price, the faster the transaction gets mined. It's best to use a higher gas price than the default.
The gas limit is the maximum amount of gas you are willing to pay for the transaction.
The nonce is the number of transactions that have been sent from the source address and is used to ensure that the transaction is unique. The transaction is unique because the nonce is incremented each time a transaction is sent.
The private key is a string parameter that can be passed to use as the signer. It is used to sign the transaction. This parameter is not needed when calling a smart contract read function.
The payment (only on Waves) payment is the payment (WAVES or Waves Asset) sent to the smart contract while interacting with it. If the smart contract function does not require any payment.
