Hold SIGN non-custodially on the Multichain network, swap into 24,000+ assets across 20+ chains via in-app DEX integrations, connect to dApps with WalletConnect, and use the value through the Zypto Premium Visa Card and Zypto's bill-pay and gift-card surfaces.

What is Sign?
Sign, also known as Sign Global, is a company building digital infrastructure for attestations, agreements, and token distribution. Its Sign Protocol is an omni-chain attestation system that lets users create, store, and verify signed records of facts across multiple blockchains. Two products sit on top of it: EthSign, a decentralized electronic agreement signing tool, and TokenTable, a platform widely used to manage token vesting and airdrops for crypto projects. SIGN is the ecosystem's token, with a total supply of ten billion. It supports the attestation and signing tools and launched in April 2025, with an airdrop distributing part of the supply to early users. You can follow the Sign price and hold SIGN in a self-custody wallet.

Sign wallet: the things people ask
What's the best Sign wallet app?
That depends on what you want to do with your SIGN. 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 Sign wallet non-custodial?
Yes. Your private keys are generated and stored on your device. Zypto never has access to your SIGN. 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.
Which chains can I swap Sign into?
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 Sign wallet?
During setup, Zypto App generates a 12-word recovery phrase. Write it down and store it offline somewhere safe. For offline hardware wallet 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.
Is Zypto App available in my country?
The wallet itself is available globally on iOS, Android and web. Some features (in-app buying, the Zypto Premium Visa Card) vary by region. See what's available where you are on our <a href="/spend-crypto/">Spend by Country</a> page.
Is Zypto App free?
