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.
