Example Code​

There are multiple ways to check for an allowance.

getAllowanceFrom()​

getAllowanceFrom() fetches the funds currently allowed by the given address to the caller:

function getAllowanceFrom(address _address) public {
    ISCAssets assets = ISC.sandbox.getAllowanceFrom(_address);
    emit AllowanceFrom(assets)
}

getAllowanceTo()​

getAllowanceTo() fetches the funds currently allowed by the caller to the given address:

function getAllowanceTo(address _target) public {
    ISCAssets assets = ISC.sandbox.getAllowanceTo(_target);
    emit AllowanceTo(assets)
}

getAllowance()​

getAllowance() gets the funds currently allowed between the given addresses:

function getAllowance(address _from, address _to) public {
    ISCAssets assets = ISC.sandbox.getAllowance(_from, _to);
    emit Allowance(assets)
}
