deposit payment (from zoe, for example) to the account
Register a handler that receives an event each time ICS-20 transfers are
sent or received by the underlying account. Each account may be associated
with at most one handler at a given time.
Does not grant the handler the ability to intercept a transfer. For a
blocking handler, aka 'IBC Hooks', leverage registerActiveTap
from
transferMiddleware
directly.
