About API3
API3 is a blockchain oracle solution that enables API providers to operate their own oracle nodes directly — called Airnode — without relying on intermediaries like Chainlink node operators. This first-party oracle model reduces attack surfaces and improves data accuracy. API3 also offers dAPIs (decentralized APIs) providing real-time price feeds for DeFi. API3 DAO governs the protocol, and QRNG (Quantum Random Number Generator) service provides provably random numbers for smart contracts.

How to Swap API3
Swapping API3 (API3) on SyntheticSwap is quick and requires no account or KYC. Since API3 is an ERC-20 token on Ethereum, any Ethereum-compatible wallet works — MetaMask, Trust Wallet, Rainbow, or Ledger Live. Open SyntheticSwap, select API3 as your source or destination asset, enter your receiving wallet address, and review the floating exchange rate. Once you send API3 to the deposit address provided, the destination asset is delivered directly to your wallet. The process is fully non-custodial — SyntheticSwap never holds your tokens at any point.
How to Store API3
API3 (ERC-20) is stored in MetaMask, Ledger, or any Ethereum-compatible wallet. For DAO governance staking visit api3.org/dao. Hardware wallets provide optimal long-term security.
