Hold SHX 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.

Your Stronghold 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 SHX 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 Stronghold?
Stronghold is a payments company, and SHX is the token tied to its network. The business builds payment products such as ACH transfers, card processing, real-time payments, and merchant financing, and SHX is the asset that connects user activity to that ecosystem. It is not a general-purpose smart-contract platform; its value is meant to come from use inside Stronghold's payment rails. SHX is native to the Stellar network, which uses the Stellar Consensus Protocol, and an ERC-20 version also exists on Ethereum via a third-party bridge. The token is used for rewards earned by merchants and customers on transaction volume, for liquidity that backs Stronghold's lending product, and for governance votes weighted by holdings. An early airdrop of roughly 5% of supply went out to users at the end of 2018. SHX is a niche, company-led token rather than a broad community network, so weigh that when researching it. You can check the Stronghold price and keep SHX in a self-custody wallet you control.

Stronghold (SHX) wallet: the things people ask
What's the best Stronghold wallet app?
That depends on what you want to do with your SHX. 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.
