NGRAVE releases ZERO Firmware 1.8 with Universal QR Protocol and Polygon token support

August 27, 2026 – NGRAVE has released firmware 1.8 for its ZERO hardware wallet, introducing the open-source Universal QR Protocol, faster QR scanning and expanded support for tokens on Polygon. The update also improves fingerprint performance, stability and the overall user experience.

The Universal QR Protocol replaces ZERO’s previous QR communication format for wallet synchronization and transaction signing. Published under the MIT license, it is designed as an open, multi-blockchain standard that developers and security researchers can inspect, verify and build on.

For users, one of the most noticeable changes is faster QR communication. The new animated QR format uses compact, redundant data, allowing scanning to begin at any point in the sequence without waiting for it to restart. Both synchronization and transaction signing become faster and more reliable.

Expanded Polygon support

Firmware 1.8 expands ZERO’s asset support with Polygon tokens, including USDC, USDT0, WETH, WBTC, DAI, AAVE, LINK and UNI. The update also adds PAXG and AMP on Ethereum and USDT on MultiversX.

At the same time, NGRAVE has streamlined the device’s asset list by removing inactive, duplicated and legacy tokens. BNB Beacon Chain and Groestlcoin support have also been discontinued, while BNB on BNB Smart Chain remains supported.

Verify, don’t trust

The Universal QR Protocol makes communication between ZERO and NGRAVE LIQUID visible and independently verifiable. Every transfer uses an open QR format that can be decoded with independent tools, giving users greater transparency into what their device is communicating.

Built on the Blockchain Commons UR ecosystem, the protocol extends support across multiple blockchains, tokens and NFTs. Its specifications, libraries and registry are publicly available, with the registry open to community contributions.

“We designed the ZERO so nothing invisible ever crosses into or out of it. Opening the Universal QR Protocol is the last step: now you don’t even have to take our word for what the QR codes say.” – Roy, CEO of NGRAVE.

NGRAVE LIQUID already supports Universal QR, so users only need to update their ZERO to firmware 1.8, more information is available on the official website.
