Package feegrant provides functionality for authorizing the payment of transaction
|
|
fees from one account (key) to another account (key).
|
|
|
|
Effectively, this allows for a user to pay fees using the balance of an account
|
|
different from their own. Example use cases would be allowing a key on a device to
|
|
pay for fees using a master wallet, or a third party service allowing users to
|
|
pay for transactions without ever really holding their own coins. This package
|
|
provides ways for specifying fee allowances such that authorizing fee payment to
|
|
another account can be done with clear and safe restrictions.
|
|
|
|
A user would authorize granting fee payment to another user using
|
|
MsgGrantAllowance and revoke that delegation using MsgRevokeAllowance.
|
|
In both cases, Granter is the one who is authorizing fee payment and Grantee is
|
|
the one who is receiving the fee payment authorization. So grantee would correspond
|
|
to the one who is signing a transaction and the granter would be the address that
|
|
pays the fees.
|
|
|
|
The fee allowance that a grantee receives is specified by an implementation of
|
|
the FeeAllowance interface. Two FeeAllowance implementations are provided in
|
|
this package: BasicAllowance and PeriodicAllowance.
