Gem

Gem Wallet is a self-custody mobile cryptocurrency wallet for iOS and Android that puts broad multi-chain access and full Solana ecosystem support in a single, privacy-first application. Launched in 2023, it covers over 100 blockchains, more than 1,000 coins and tokens, and NFTs, without ever requiring an account, KYC verification, or access to a user's private keys.

Self-Custody Without Compromise

The core design principle of Gem Wallet is strict self-custody: private keys are generated on-device, encrypted with AES-256, and never transmitted to any server. iOS users benefit from Secure Enclave protection; seed phrases follow BIP-39 standards and are stored locally. The wallet logs no IP addresses, holds no user balances server-side, and tracks no personal data. Authentication relies on biometrics such as Face ID, Touch ID, or fingerprint, alongside an optional PIN.

This zero-server-knowledge architecture means Gem Wallet cannot recover lost seed phrases, which the app communicates plainly to users during setup. The trade-off is that users bear full custody responsibility: the wallet provides the tools, and users retain the keys.

Security and Open-Source Transparency

Gem Wallet is fully open-source under a GPL-3.0 license, with the primary iOS and Android codebase publicly available on GitHub. The wallet is built with Rust for core cryptographic infrastructure, Swift and SwiftUI for iOS, and Kotlin with Jetpack Compose for Android. The open codebase is available for independent review, and the project also distributes an APK through F-Droid for users who prefer to avoid proprietary app stores.

In April 2026, Gem Wallet completed a CertiK security audit covering key management, transaction signing, seed phrase handling, and address derivation. The audit found zero critical and zero high-severity vulnerabilities across both iOS and Android builds. Gem Wallet accepts responsible disclosure from security researchers, though it no longer runs a monetary bug bounty program.

Solana Support

Gem Wallet provides comprehensive Solana ecosystem coverage. The wallet supports the full SPL token standard, including major assets such as USDC, USDT, JUP, RAY, and BONK, with live price feeds and full transaction history built in. Solana NFTs can be stored and transferred within the app alongside NFT preview functionality.

For swapping on Solana, Gem Wallet integrates with Jupiter, the leading Solana DEX aggregator, to source best-available rates across liquidity pools. Users can also access cross-chain swaps that include Solana as a source or destination chain through integrations with Mayan, Chainflip, THORChain, Maya Protocol, and NEAR Intents.

Native SOL staking is available directly within the app, letting users delegate stake without leaving the wallet interface. Transaction speed on Solana is adjustable across Slow, Normal, and Fast settings, giving users control over fee prioritization. The wallet is listed among official wallets by the Solana Foundation.

Multi-Chain Reach

Beyond Solana, Gem Wallet supports Bitcoin, Ethereum, XRP, TRON, BNB Chain, Base, TON, Arbitrum, Polygon, Hyperliquid, Monad, Sei EVM, Robinhood Chain, and dozens of additional Layer 1 and Layer 2 networks. Stablecoins across over 20 assets are supported, including ERC-20, TRC-20, and BEP-20 token standards.

Native staking is available for 14 tokens including SOL, TRX, and SEI, all managed without leaving the app. The built-in DEX aggregator has processed over 100 million dollars in swap volume across supported chains.

Fiat On-Ramp and Accessibility

Users can purchase crypto directly within the app through a fiat on-ramp that accepts Apple Pay, major credit and debit cards, and bank transfers across more than 170 countries via more than 30 payment providers. This makes Gem Wallet a viable entry point for users new to crypto as well as a practical tool for experienced holders managing multiple chains.

The interface is available in over 25 languages, and the app is designed to serve both newcomers and experienced DeFi users within the same interface, simplified enough for a first purchase of SOL yet capable of managing complex cross-chain swap routes.

Traction and Community

As of mid-2026, Gem Wallet has over 500,000 users and holds a 4.9-star rating on the App Store (458 ratings) and a 4.8-star rating on Google Play (2,845 reviews). The GitHub repository has accumulated approximately 745 stars. The project maintains active community channels on Discord and Telegram, and updates are published via the Gem Wallet blog at gemwallet.com/learn, which covers both product announcements and educational content across the blockchains the wallet supports.
