Your OpenGradient is secured by you
Zypto App is non-custodial. Your private keys are generated and stored on your device, Zypto never has access to your OPG and every transaction is signed locally. For account access, every user sets a PIN with optional biometric security (fingerprint or face recognition). You can also filter your wallet to show only verified tokens, protecting you from random airdrops or unsafe assets. 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 OpenGradient?
OpenGradient is a decentralized AI infrastructure network built for verifiable AI inference. The idea is that AI model calls can be cryptographically checked before their results are settled on-chain, so the computation is auditable rather than opaque. It also runs a Model Hub, an open store where developers can upload, share, and access AI models in a censorship-resistant way. OPG is the network's native token. It is used to pay for inference, to monetize models, for staking and network security, for application access, and for governance. OpenGradient is its own blockchain, designed from the ground up around verifiable AI, and the OPG token went live through a token generation event on April 21, 2026. As a newly launched AI-and-crypto network, OpenGradient is early-stage, so understand how its inference and token model work before relying on them. You can check the OpenGradient price and hold OPG in a self-custody wallet.

What's the best OpenGradient wallet app?
That depends on what you want to do with your OPG. 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.

Yes. Your private keys are generated and stored on your device. Zypto never has access to your OPG. Every transaction is signed locally on your device before it reaches the network.
