Edge

Edge is a non-custodial mobile cryptocurrency wallet that replaces seed phrases with a username-and-password login while keeping all private keys encrypted on the user's device — not on Edge's servers.

What Edge Does

Edge lets users store, buy, sell, and swap more than forty cryptocurrencies from a single mobile app on iOS and Android. The core promise is self-custody without setup friction: there are no seed phrases to transcribe at onboarding. Instead, users create an account with a username and password, and the app handles encrypted backup and cross-device sync automatically. When a user installs Edge on a new phone and logs in, their wallets restore from encrypted cloud backups without any manual seed entry.

Supported assets span the major ecosystems: Bitcoin, Ethereum, Solana, XRP Ledger, Litecoin, Monero, Dogecoin, Stellar, Tron, BNB Smart Chain, Avalanche, Polygon, Optimism, zkSync, Base, TON, and more. Token standards covered include ERC-20, BEP-20, TRC-20, and SPL — the last of which covers Solana-based tokens.

How It Works: Client-Side Encryption and Zero-Knowledge Architecture

Edge's security model is built around a principle the company calls zero-knowledge architecture. When a user creates an account, the private keys and wallet data are generated locally on the device. Before any data reaches Edge's servers, it is encrypted using Scrypt-based key derivation tied to the user's password. Edge's servers store only the encrypted blob; the company has no ability to decrypt it, access keys, or reconstruct wallet contents.

Day-to-day access uses biometric or PIN unlocking without reducing this encryption guarantee, since those methods simply gate access to locally cached credentials rather than transmitting anything sensitive. Approvals and transaction signing happen on the device itself.

A notable security feature is Duress Mode, which lets users set up a decoy account that opens under a different password during a coercive situation. This is aimed at users who face physical threats or high-pressure scenarios where they might be forced to unlock their wallet.

Cross-device security requires additional steps: logging in from an unrecognized device triggers a hold of seven or more days unless the user approves the new device from an already-authenticated session or provides a stored two-factor code. This reduces account takeover risk in case credentials are compromised.

Key Features

Built-in swaps. Edge integrates multiple decentralized exchange and routing providers — including THORChain, Maya Protocol, LI.FI, Rango, and 0x — so users can swap across chains without leaving the app. THORChain and Maya enable cross-chain swaps between native assets such as Bitcoin and Ethereum without wrapped tokens or bridges. Edge added support for private Zcash swaps through Maya Protocol in late 2025.

Fiat on-ramps and off-ramps. Multiple regional buy and sell providers allow users to purchase crypto directly with bank transfers, debit cards, and payment services like PayPal and Apple Pay. Costs vary by method and region, with bank transfers typically running 1.5–2% and card purchases 3.5–7%.

Staking and yield. Edge surfaces staking options for select assets, including THORChain Savers for Bitcoin and Ethereum staking through Kiln. Availability depends on the specific asset and region.

Gift cards and mobile top-ups. The Bitrefill integration allows users to spend crypto on gift cards and prepaid mobile top-ups from within the app, adding a practical spending layer without requiring a fiat offramp first.

WalletConnect. Mobile WalletConnect support lets users connect to decentralized applications via QR code scan from their phone, giving access to DeFi protocols from the Edge interface.

Privacy features. A 2026 integration with the NYM Mixnet allows users to route traffic through a decentralized mixnet, obfuscating transaction metadata at the network level rather than just on-chain.

Solana Ecosystem Fit

Edge treats Solana as a first-class supported network. SOL and SPL tokens are manageable from the main wallet interface alongside Bitcoin and Ethereum holdings. Solana users benefit from the same account-based backup model, meaning SOL wallets restore automatically on new devices through the encrypted cloud sync rather than requiring users to manually enter a seed. The lack of a browser extension means Edge is not positioned for heavy Solana DeFi use requiring frequent dApp interactions — for that workflow, a dedicated extension wallet such as Phantom or Backpack is better suited — but Edge serves users who want a mobile-first, multi-chain wallet that includes Solana alongside other major assets.

Token

Edge does not have a native protocol token. Revenue comes from swap spreads and on-ramp provider arrangements rather than token issuance.

Team and History

Edge was developed by Airbitz Inc., the company that originally launched the Airbitz Bitcoin wallet in the early days of the mobile wallet market. The product was rebranded as Edge in 2017 to reflect its expansion to multi-asset support beyond Bitcoin. The codebase is open source on GitHub under the EdgeApp organization.

Security Incidents and Audits

A security incident in 2023 affected approximately 600 wallets — roughly 0.02% of the platform's total wallets at the time. The vulnerability exposed private keys under specific conditions involving certain partner buy/sell interface screens combined with the log upload function. Edge patched the issue in version 3.3.1 and notified affected users to migrate funds. The company has a public bug bounty program.

Limitations

Edge is mobile-only. There is no dedicated desktop application, browser extension, or web wallet. Users who require hardware wallet pairing with Ledger or Trezor cannot do so through Edge, since the app does not support hardware signing devices. The mobile constraint also limits workflows that depend on dApp browser extension injection, which is common in Solana DeFi.
