How can users in different federations transact? Does this involve an on-chain tx?
can't find this in the docs.. pls send link if i missed.
federations can interact with each other through the lightning network via lightning gateways, no on-chain tx required: fedimint_a -> lightning_gateway_a -> lightning_network -> lightning_gateway_b -> fedimint_b

ok, i found this
  1. Why would a LN gateway provider accept "fm-sats"? What guarantees them this can be redeemed for sats. Trust the federation?
  2. Can a federation be the LN G-provider themselves using the pegged-in sats thus acting as a custodial LN wallet?
reply
A couple thoughts:
Yes, a gateway does have to trust the federation that they can swap ecash for sats later. However, users and federation members do not have to trust the gateway.
Therefore, a federation member providing gateway services is totally plasible IMO. It would not turn the relationship into a custodian (still federated). Running a successful lightning node does take more skill than running a federation, so I would imagine not every federation would be able to provide this. I can imagine that federations might eventually pay a deposit to a gateway for this.
