For offline hardware wallet security, pair with the Vault Key Card, card-based cold-wallet hardware that signs transactions over NFC, keys never touch the internet.
What is Harmony?
Harmony is a layer 1 blockchain that is compatible with the Ethereum Virtual Machine, so developers can deploy Ethereum-style smart contracts and applications on it. Its design centers on sharding, which splits the validator set and the network state into parallel groups so transactions can be processed at the same time rather than one queue at a time. The goal is faster confirmation and lower fees than running directly on Ethereum. The network uses an Effective Proof of Stake consensus that spreads stake across validators to encourage decentralization, with around two second finality. ONE is the native coin: it pays transaction fees, is staked to secure the network, and is used in governance. Harmony launched its mainnet in 2019. As an established but competitive layer 1, Harmony's activity depends on the developers and users building on it. You can follow the Harmony price and hold ONE in a self-custody wallet.

Harmony wallet FAQs
What's the best Harmony wallet app?
That depends on what you want to do with your ONE. If you're holding only, any non-custodial wallet works. If you want to hold, swap across 20+ chains, connect to dApps, and use crypto for real-world spending, Zypto App is purpose-built for that while still being fully non-custodial.
Is the Zypto Harmony wallet non-custodial?
Yes. Your private keys are generated and stored on your device. Zypto never has access to your ONE. Every transaction is signed locally on your device before it reaches the network.
How do I spend crypto with Zypto Premium Visa Cards?
When you load the card in Zypto App, your crypto is converted into USD. Conversion happens at load, not at the checkout, so you can lock value in, avoid volatility and spend wherever Visa is accepted around the world, subject to eligibility and applicable limits.

Swap into assets across 20+ chains including Ethereum, Solana, Polygon, Arbitrum, Optimism, BNB Chain and TRON, across 1,000,000+ cross-chain routes. All in-app, all in two taps.
How do I back up my Harmony wallet?
During setup, Zypto App generates a 12-word recovery phrase. Write it down and store it offline somewhere safe.
