Hackathon Galactica: Results

Tether's first hackathon on agentic payments wrapped on March 22. The numbers exceeded expectations: 484 participants signed up and 206 projects were submitted across four tracks - Agent Wallets, Lending Bot, Autonomous DeFi Agent, and Tipping Bot. Over 30,000 USDt in prizes will be distributed.

This was the first large-scale stress test of WDK by a broad developer audience, and the results showed the SDK holds up. We are reviewing the submissions now and will share winning projects in the next issue.

• wdk-wallet-btc (v1.0.0-beta.6) - Refactored to use a single Electrum client per WalletManager, reducing connection overhead. CI now supports bitcoind + electrs for automated testing.
