ERA Launches Software Wallet Companion, Expands Hardware Ecosystem

The ERA Software Wallet companion app now brings portfolio oversight, cross-chain swaps, and dApp connectivity across 14 networks to ERA hardware wallet users, with private keys remaining on the device. This release follows a complete Cure53 security audit and coincides with a major ERA Lens upgrade and new hardware features like Bitcoin multisig and on-device 2FA.

ERA, which produces the air-gapped ERA hardware wallet, has unveiled the ERA Software Wallet, a mobile companion for iOS and Android designed to transform the hardware device into a comprehensive self-custody environment. This initiative tackles a frequent challenge in crypto self-custody: hardware wallets provide strong security but are often cumbersome for everyday use, while software wallets offer convenience at the cost of keeping keys online.

ERA's approach maintains a clear separation — the mobile app prepares transactions, the hardware device signs them, and private keys never reach the phone.

“People don’t abandon self-custody because they don’t believe in it – they abandon it because it’s inconvenient,” said Alex Devyatkin, founder and CEO of ERA. “The Software Wallet doesn’t change what secures your assets. It changes how easy it is to actually use that security every day.”

What’s in the ERA Software Wallet

The mobile app provides a unified interface for managing holdings across 14 networks — including Bitcoin (SegWit, Taproot, and Legacy address types), Ethereum, Solana, Tron, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, zkSync, Kaia, and Aurora. Every transaction still requires confirmation and signing on the ERA hardware device via QR code or NFC.

Within the app, users can:

• View portfolio balances across all supported networks, with each token clearly tagged by network
• Send and receive assets, with a network guard that prevents funds from being sent to the wrong chain
• Buy and sell crypto through integrated providers, with automatic KYC/country detection and side-by-side rate comparison
• Swap and bridge across chains in a single flow, powered by Rango’s routing, with a full quote shown before signing
• Connect to dApps via WalletConnect, with sessions still requiring hardware-signed approval
• Get proactive protection: warnings on unused token approvals, a spam-token filter, alerts on pending or stuck transactions, and full transaction history

Security at the app level includes PIN and biometric unlock (Face ID, Touch ID, or fingerprint), auto-lock when the app enters the background, and screen-privacy measures that hide content from the system app switcher while blocking screenshots and screen recording.

Backed by an Independent Security Audit

Before launch, ERA engaged Cure53, a cybersecurity firm known for auditing wallets and crypto infrastructure, to conduct a full white-box security review. Cure53 received access to source code, builds, documentation, and internal components, testing the mobile app, API, transaction construction, and QR/BC-UR signing flows. ERA’s team addressed every identified issue, and Cure53 retested to verify each fix remained effective.

The Headline Device Update: ERA Lens’s New Scam-Warning System

The primary device-side update involves ERA Lens, ERA’s transaction-decoding layer that translates transaction actions into plain language before signing rather than displaying raw hex data.

This version introduces a new scam-warning display, extends support to additional DeFi and bridging protocols (including Rango, imToken, Rabby, MetaMask Portfolio Bridge, Mayan, Squid, LayerSwap, Stargate V2, GasZip, and Magpie), and can now decode recently introduced harder-to-read transaction formats such as EIP-7702, ERC-7821, and Safe multicalls — automatically flagging unlimited approvals to unknown addresses.

ERA added 37 real transactions from known incidents — including Bybit, WazirX, Radiant, Inferno Drainer, and PREMINT — to its automated test suite, ensuring every new firmware release is verified against these attack patterns before deployment.

Extended Protection, Built Into the App

On the mobile side, the Software Wallet adds enhanced protection targeting scams that directly attack wallet users rather than the underlying blockchain. The home screen now displays a plain-language warning for unused token approvals, with a dedicated screen showing exactly which contract can spend how much of which token, on which network, revocable in one confirmation.

The app also defends against address poisoning — fake transaction records designed to trick users into copying a lookalike address from their history. Between July 2 and August 1, 2026, ERA tracked 66 such fake entries across 24 poisoned addresses, spanning 8 wallets and 8 networks; if a recipient address closely matches one of a user’s own addresses, sending is blocked without override.

Also New: Progressive Security on the Hardware Device

Alongside the software wallet release, ERA is adding new capabilities to the hardware device itself, continuing its “wallet you never outgrow” model that lets users upgrade to more advanced security without switching hardware.

• Bitcoin multisig support – the ERA device can serve as one cosigner in a Bitcoin multisig setup, such as holding one key in a 2-of-3 arrangement, eliminating any single point of failure.
• On-device two-factor authentication – TOTP authentication codes can now be stored directly on the ERA hardware device, adding a second layer of digital security on the same hardware protecting private keys.
• Device authenticity verification – separately from transaction signing, the ERA device can prove it is genuine and unmodified by signing a one-time challenge with a factory-burned key, a process taking under a minute.
