approveMax
The approveMax
method can be used to approve max amount on the root token.
const erc20RootToken = posClient.erc20(<root token address>, true);
const approveResult = await erc20RootToken.approveMax();
const txHash = await approveResult.getTransactionHash();
const txReceipt = await approveResult.getReceipt();
spenderAddress
¶
The address on which approval is given is called spenderAddress
. It is a third-party user or a smart contract which can transfer your token on your behalf.
By default spenderAddress value is erc20 predicate address.
You can specify spender address value manually.
const erc20RootToken = posClient.erc20(<root token address>,true);
// approve 100 amount
const approveResult = await erc20Token.approveMax({
spenderAddress: <spender address value>
});
const txHash = await approveResult.getTransactionHash();
const txReceipt = await approveResult.getReceipt();
