Keeping your Api3 safe - how Zypto handles security
Zypto App is non-custodial. Your private keys are generated and stored on your device. Zypto never has access to your API3, and every transaction is signed locally. For higher security, pair with the Vault Key Card, the card-based cold-wallet hardware that signs transactions over NFC without exposing keys to the internet.
What is Api3?
API3 is a decentralized oracle project that connects real-world data to smart contracts. Instead of relying on third-party middlemen, it lets data providers run their own oracle nodes, called Airnodes, and deliver information to blockchains directly through decentralized APIs known as dAPIs. This first-party approach is meant to make data feeds more transparent and accountable. API3 is an ERC-20 token on Ethereum that governs the project through a DAO. Holders can stake API3 to take part in governance, help secure the network, and earn staking rewards, with staked tokens also serving as collateral that backs data-feed reliability. The project launched in late 2020. You can follow the API3 price and hold API3 in a self-custody wallet.

Api3 wallet: the things people ask
What's the best Api3 wallet app?
That depends on what you want to do with your API3. If you're holding only, any non-custodial wallet works. If you also want to use Api3 for real-world spending through the Zypto Premium Visa Card, pay bills, top up phones, or swap into other assets, Zypto App is purpose-built for that while still being fully non-custodial.
Is the Zypto Api3 wallet non-custodial?
Yes. Your private keys are generated and stored on your device. Zypto never has access to your API3. Every transaction is signed locally on your device before it reaches the network.
Can I use Api3 for real-world spending without selling it?
Through the Zypto Premium Visa Card, your API3 balance is converted at the point of sale, so you use the value of your crypto for real-world spending wherever Visa is accepted, subject to eligibility and applicable limits. You can also swap API3 into stablecoins in-app for bill pay or gift cards.
Which chains can I swap Api3 into?
20+ chains including Ethereum, Solana, Polygon, Arbitrum, Optimism, BNB Chain and TRON. Cross-chain swaps happen inside Zypto App, no separate wallets required.
How do I back up my Api3 wallet?
During setup, Zypto App generates a 12-word recovery phrase. Write it down and store it offline somewhere safe. For higher security, pair Zypto App with a Vault Key Card, the card-based cold-wallet hardware that signs transactions over NFC without exposing your keys to the internet.
