Upoch provides checkpointing and recovery tools for autonomous agent workflows. Its SDK can capture workflow state at chosen steps or around external actions, encrypt and store checkpoint data off-chain, and commit linked hashes to a contract on Robinhood Chain. After a failure, an agent can verify and restore a checkpoint, reconcile uncertain actions, and resume; guardians can participate in policy-governed recovery. Upoch also offers a web console with workflow history and a time-travel debugger. Its protocol does not prove that an agent executed correctly or reverse transactions that already occurred.
