Authorizations

Summary

The marker module supports granting authorizations for restricted coin transfers through the authz module's Authorization interface using MarkerTransferAuthorization, which allows a granter to permit a grantee to execute restricted coin transfers on their behalf with configurable transfer limits and optional destination address restrictions.

The marker module supports granting authorizations for restricted coin transfers. This is implemented using the authz module's Authorization interface.

protobuf
// MarkerTransferAuthorization gives the grantee permissions to execute
// a restricted coin transfer on behalf of the granter's account.
message MarkerTransferAuthorization {
  option (cosmos_proto.implements_interface) = "Authorization";

  // transfer_limit is the total amount the grantee can transfer
  repeated cosmos.base.v1beta1.Coin transfer_limit = 1
    [(gogoproto.nullable) = false, (gogoproto.castrepeated) = "github.com/cosmos/cosmos-sdk/types.Coins"];

  // allow_list specifies an optional list of addresses to whom the grantee can send tokens on behalf of the
  // granter. If omitted, any recipient is allowed.
  repeated string allow_list = 2;
}

With the MarkerTransferAuthorization a granter can allow a grantee to do transfers on their behalf.

A transfer_limit is required to be set for the grantee.

The allow_list is optional. An empty list means any destination address is allowed, otherwise, the destination must be in the allow_list.
