The $250 prize went to hippo, a multi-platform agent that anchors memory to a user-owned, revocable Walrus account, and the $150 prize to Anchor, a Telegram accountability agent that tracks commitments, schedules check-ins and logs follow-through over time.

Yosuku lets AI agents trade Bitcoin predictions on DeepBook Predict

Yosuku, a Bitcoin prediction market app built on DeepBook Predict and currently in TestFlight testing, said AI agents can now place Bitcoin predictions for users. Users approve once and set spending limits, which Yosuku said are enforced by Sui so an agent cannot spend more than allowed. Yosuku said users need no SUI and pay no gas fees because it covers gas, and that any winnings can only go back to the user's wallet.
