# Introduction SwipeChain comes to consensus about events observed on external networks via witness transactions from nodes. Swap and stake logic is then applied to these finalised events. Each event causes a state change in SwipeChain, and some events generate an output transaction which require assets to be moved (outgoing swaps or bond/liquidity withdrawals). These output transactions are then batched, signed by a threshold signature scheme protocol and broadcast back to the respective external network. The final gas fee on the network is then accounted for and the transaction complete. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
