STRK security in Zypto: where your keys actually live
Zypto App is non-custodial. Your private keys are generated and stored on your device. Zypto never has access to your STRK, 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 Starknet?
Starknet is a ZK rollup on Ethereum built by StarkWare. It uses STARK cryptographic proofs to verify large batches of transactions, settling the results on Ethereum with strong security guarantees inherited from the main chain. Applications on Starknet are written in Cairo, a programming language designed for provable computation. The STRK token launched in 2024 and is used for gas fees and staking within the network. Starknet's design focuses on scalability without compromising on the settlement security of Ethereum. As of early 2026, Starknet is one of the more technically ambitious Ethereum scaling solutions, with a growing DeFi and gaming ecosystem. You can track the Starknet price and hold STRK in a self-custody wallet.

STRK wallet questions, answered
What's the best Starknet wallet app?
That depends on what you want to do with your STRK. If you're holding only, any non-custodial wallet works. If you also want to use Starknet 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 Starknet wallet non-custodial?
Yes. Your private keys are generated and stored on your device. Zypto never has access to your STRK. Every transaction is signed locally on your device before it reaches the network.
Can I use Starknet for real-world spending without selling it?
Through the Zypto Premium Visa Card, your STRK 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 STRK into stablecoins in-app for bill pay or gift cards.
