DeFi Mullet Hackathon #1: Builder Edition
DeFi Mullet is a hackathon series for builders who want to ship real DeFi yield products — not pitch decks or mockups, but working code that puts money to work.
About
The first edition kicks off April 8th. You get time until April 14th to build on [LI.FI Earn](https://docs.li.fi/earn/overview) — a single API that connects you to 20+ vault protocols across 60+ chains with one-click deposit execution. No more stitching together custom integrations protocol by protocol, chain by chain. This is an early builder edition, which means smaller crowd and better odds of winning the bounty. If you've been looking for a reason to start building in DeFi yield — this is it.
