getAllowance

The getAllowance method can be used to get the approved amount for the user.

const erc20Token = posClient.erc20(<token address>, true);

const balance = await erc20Token.getAllowance(<userAddress>);

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 erc20Token = posClient.erc20(<token address>, true);

const balance = await erc20Token.getAllowance(<userAddress>, {
    spenderAddress: <spender address value>
});
