Create Tokens via Portkey AA Address

1. Obtain SEED​

Refer to Obtain SEED

2. Create token​

Create by using ManagerForwardCall in the AA contract and calling the Token contract.

Please note: the contract called is on the MainChain but you can decide to create tokens whether on the MainChain or dAppChains via the parameter issue_chain_id (issueChainId in the below demo).

Obtain chain information​

You can use the methods below to query each chain's info and the info about the AA contract or Token contract. Select MainChain AELF as the token creation chain.

import { did } from '@portkey/did';
const chainList = await did.services.getChainsInfo();

Obtain wallet information​

Please note: the Portkey account should be logged in.

import { did } from '@portkey/did';

const { wallet } = did.didWallet.managementAccount;

Initialize contract​

import { getContractBasic } from '@portkey/contracts';

const contract = await getContractBasic({
  contractAddress: TOKEN_CONTRACT_ADDRESS, // MultiToken contract address
  account: wallet, // Provide the wallet info from the last step
  callType: 'ca', // Set the initialising contract type as AA contract
  caContractAddress: 'AA contract address',
  caHash:  did.didWallet.caInfo.AELF.caHash, // CaHash of the account
  rpcUrl: 'aelf blockchain node address'
});

Create by calling contract methods​

For parameter details, refer to contract documentation: https://docs.aelf.io/en/latest/reference/smart-contract-api/multi-token.html

Create by using the callSendMethod method in the AA contract and calling the Token contract.

const { data: { TransactionId } } = await contract.callSendMethod('Create', wallet.address, {
    symbol: 'TEST TOKEN',
    tokenName: 'TEST TOKEN NAME',
    totalSupply: 'Total amount of tokens can be created',
    decimals: 'token decimals',
    issuer: 'Target issuer address',
    isBurnable: 'Set the token to be burnable or not',
    issueChainId: 'ID of the chain where the token will be issued',
});

3. Issue​

Issue by using the callSendMethod method in the AA contract and calling the Token contract.

const result = await contract.callSendMethod('Issue', wallet.address, {
  symbol: 'TEST TOKEN',
  to: 'Target issuer' ,
  amount: 'Total amount of tokens can be issued'
});

Process of Portkey account creating tokens​

AA operation --- set MainChain as issue_chain_id​

set-side-chain

AA operation --- set dAppChain as issue_chain_id​

Operations on the dAppChain can only take effect when the MainChain and dAppChain are synchronized.
