Wind a lane down

caravel destroy --env testnet
  1. Drain until every signed checkpoint is accepted, and at least one is.
  2. Stop the sequencer and the relayer.
  3. Export every account's exit proof to exit.json.
  4. Trigger, then wait out the forced-withdrawal window, so the contract allows a freeze.
  5. Freeze, so users withdraw on Stellar with their proofs.

Without --yes, destroy asks you to type the lane's name. A frozen lane can't be restarted. The validators keep serving proofs unless you pass --stop-validators, and --pay-out claims every exit for its owner.

After the freeze, each user runs caravel escape <identity>. It needs only the lane file and the admin's public key, and takes the proof from exit.json, a validator, or a replay from Stellar.

Drill a freeze​

Practice on a lane you can lose, never on one with users:

caravel stop sequencer relayer        # checkpoints stop; it prints when a freeze becomes possible
stellar contract invoke --id <settlement> --source-account <anyone> --network testnet -- freeze
caravel wait frozen
caravel escape alice
