XEL-run first
A hosted heartbeat service while the decentralized keeper successor is still future work.
DeHeart
A small open-source heartbeat service for Sui tasks, run by XEL at launch with x402 support.
Why DeHeart matters
Section titled “Why DeHeart matters”DeHeart is intentionally small at launch. XEL runs the first heartbeat service because no trustless Sui keeper network exists yet. The heartbeat is authority-free: anyone can send the same poke, and x402 is built into the access/payment path from the start.
Authority-free
The service can poke tasks, but it does not get privileged execution authority.
x402 native
Payment challenges and unsigned payment attempts are part of the launch API.
Agent-readable
OpenAPI, llms.txt, and JSON discovery make the service easy for agents to use.
Quick comparisons
Section titled “Quick comparisons”- Talus handles agent workflows. DeHeart is a smaller heartbeat service those workflows can call.
- Chainlink CRE is the mature reference for rich off-chain execution. DeHeart only borrows the clear trigger/API model.
- Future Sui keepers can replace the XEL-run worker once a trustless keeper network exists.
