DeFi primitives — swaps, lending, yield — are increasingly accessed by agents that pay per call. These projects sit at the intersection of DeFi and x402, letting agents both pay for services and interact with on-chain protocols: trading agents, paid market data, and agent-accessible liquidity.
Below are the DeFi-related projects in the directory.
The DeFi category right now
The directory currently tracks 95 DeFi projects. nofx leads the group with 12,595 stars, and 8 of them have cleared 100 stars, 4 of those past 1,000. Half the group sits at 2 stars or below, which is the honest shape of this space today: a short head of real adoption and a long tail of experiments.
TypeScript (42%) and Python (21%) dominate the implementation languages here, and plagtech is the most prolific publisher with 3 DeFi repositories. The recurring GitHub topics are defi, ai-agents, mcp.
39 of the 95 projects were updated in the last 30 days and 57 in the last 90 (60%), so this is an actively moving category. 2 have had no commit for over a year. The newest entrant is agent-symphony, first published 2026-06.
