About

Celo is a leading Ethereum L2. As the frontier chain for global impact, we're scaling real-world solutions for all. Celo, a Layer 2 built on EigenDA and OP Succinct, provides the ideal foundation for scalable consumer apps, DeFi innovation, and AI-powered agents, all running on sustainable, modular infrastructure. Since launching on Earth Day 2020, Celo’s open-source mainnet has grown into a vibrant ecosystem of 1,000+ projects working toward a shared mission: prosperity for all. At its core, the Celo Platform delivers fast, low-cost transactions and broad accessibility through fee abstraction, enabling users to pay gas fees with stablecoins. It supports a robust ecosystem of dollar-pegged and regional stablecoins, including cUSD, cEUR, cNGN, cKES, and cCOP, that collectively power a dynamic DeFi landscape built on protocols like Uniswap V3, Aave, Velodrome, Morpho, and more. Now, it’s your turn to build on top of this foundation. With Celo’s powerful dev tooling, you can launch a MiniApp for Farcaster or for MiniPay, the Celo wallet used by 10+ million people and growing, in just minutes. From DeFi micro-tools to on-chain identity, rewards, or AI-powered interactions, your MiniApp could be the next big leap in accessible Web3 experiences.

In most L1 and L2 networks, transaction fees can only be paid with a single, often volatile, native asset. On Celo, you can simplify sending funds by paying fees with stable ERC20 tokens like USDT, USDC, cUSD, and others, as well as CELO. To qualify for this bounty, add a feeCurrency field to the transaction objects in your dApp to enable this feature.
