# Allowance management logic The `handleAllowance` internal function defines the logic for when an Allowance is being used. Allowance usage is broken down in the Payments Through Snowflake section. Allowances **must** be set by an `EIN` for a Resolver in order for the Resolver to operate on them. Allowances can be set when the Resolver is added, and they can be changed at any time. Once an allowance is set, a Resolver may withdraw from the `EIN`‘s HYDRO balance up to the quantity of the Allowance. When executing resolver-initiated payments, `handleAllowance` checks that: * The `Resolver` is set for the `EIN` * The balance being used by the `Resolver` is within the `Resolver`‘s allowance. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
