XFTMultiAssetSwap_V2 0x43A8a85A2E8bc98D1c54c3244C3b61230b3cf5E6arrow-up-right

Atomic swap using Hash Time Locked Contracts (HTLC). Initiator deposits basket of tokens (LNT, UTSGEN, XFTA15), participant deposits USDXT. Both parties commit funds to contract with shared secret hash. Either party reveals secret to claim counterparty funds, or timelock expires for refunds.

FLOW

1 Initiator locks multiple tokens, sets hashlock/timelock 2 Participant locks single whitelisted token (USDXT) 3 Secret reveal triggers simultaneous token exchange 4 Emergency refund after timelock + 1 day
