Description
Api3 DAO is the decentralized governance framework managing the Api3 oracle protocol through API3 token staking on Ethereum mainnet. Token holders stake API3 into the DAO pool to participate in governance votes and earn staking rewards, with staked tokens also serving as collateral guaranteeing oracle service quality. The Aragon-based governance structure uses dual primary and secondary voting agents for different proposal categories including staking parameters, collateralization ratios, and treasury grants.Category: DAO Management Platform

Api3 Market
Project Links
Description
Api3 Market is a permissionless data feed marketplace delivering 190+ real-time price feeds to DeFi protocols across 34 EVM mainnets. The platform uses first-party oracle nodes operated directly by API providers, eliminating data intermediaries. Integrated OEV infrastructure auctions exclusive update rights to MEV searchers and distributes 80% of auction proceeds as OEV Rewards to the dApp in the chain's native gas token monthly. Data feeds implement AggregatorV2V3Interface, enabling drop-in replacement for Chainlink price feeds.Category: Oracle
Airnode
Project Links
Description
Airnode is serverless oracle node software enabling API providers to run first-party oracle nodes that deliver cryptographically signed data directly to smart contracts. Operators configure Oracle Integration Specifications (OIS) to map existing REST API endpoints into blockchain-compatible data formats and deploy through managed cloud infrastructure. By having API providers sign their own data at the source, Airnode establishes cryptographic attribution for on-chain oracle feeds.Category: Developer Tooling
