In a forum conversation, ZmnSCPxj explains that spends from swap-in-potentiam addresses are safely 0-conf if Bob is the other signatory in the swap-in-potentiam address. However, ZmnSCPxj believes that swap-in-potentiam can be considered cheating since sending to this address is actually a channel open of a Spilman-like channel with `OP_CSV` instead of `OP_CLTV`. Swap-in-potentiam provides implicit protection against 0-conf double-spend risk for all operations that move from on-chain to Lightning. UTXOs with swap-in-potentiam addressed do need to be confirmed.ZmnSCPxj also suggests considering a proposal for cases where splice-in is done by an LSP and the other side is a client of that LSP. The proposal is designed for 0-conf channel funding, but the protocol is generic enough that it can be used where there is double-spend risk from an LSP, which the client wants to protect against.
