Where agent payments meet on-chain finance.
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.

We currently track 93 DeFi projects in the directory, drawn from open-source repositories building on x402 and agent payments. The list above is sorted by GitHub stars and updates as new projects are submitted and crawled.
x402 is an open standard for paying for an HTTP resource: a server replies with HTTP 402 and payment terms, the client pays (usually USDC), and the request is fulfilled. The DeFi projects above implement or build on this flow.
Submit it from the Submit page. We crawl the repository, classify it, and it appears in the relevant category pages — including this one if it matches.
