Firmware 1.8 · Out now

The Foundational Update

Your ZERO now speaks the open Universal QR Protocol — one language for every asset it supports, published for anyone to read, verify, and build on.

The visible channel

Security you can see

Most hardware wallets talk to their app over USB, Bluetooth or NFC — that exchange happens out of sight. Universal QR makes every message between ZERO and LIQUID visible, and open to inspection.

Before you sign

Communication you can verify

Before you scan, you can check exactly what your ZERO displays. Once scanned, the exchange follows an open format anyone can independently decode — no hidden channel, just transparent data.

The upgrade

Introducing Universal QR

Firmware 1.8 brings Universal QR to every asset ZERO supports. Published open source under MIT — for you to trust today, and for developers to build on tomorrow.

The Universal QR Protocol

One protocol. Every supported asset.

Instead of a separate QR format for every ecosystem, Universal QR uses one consistent language across every blockchain, token and NFT ZERO supports — and it can grow alongside the assets you use. Watch USDC on Polygon announce itself:

1 · Curvesecp256k1IANA COSE registry
2 · CoinEthereum · 60SLIP-44 type
3 · ChainPolygon · 137EVM chain ID
4 · AssetUSDCERC-20 token
MIT licensedBuilt on Blockchain Commons URRegistry open to pull requestsBitcoin stays standard PSBT

LIQUID already supports the protocol — you only update your ZERO. And because the specification is open, any developer can build compatible software. That's what an open standard makes possible for self-custody.

Transparency

Verify, don't trust

Every transfer between ZERO and LIQUID is an open QR anyone can decode with independent tools. Copy just the highlighted string below into an independent decoder:

Speed

Start scanning anywhere

Raise your phone late, miss the first frames — it doesn't matter. The animated QR runs a compact, redundant loop, so the full payload arrives within a single pass no matter where you start watching. There is no beginning to catch.

ZERO 1.8

Release notes

Universal QR Protocol

Sync and signing move to the open, multi-blockchain standard — replacing the legacy QR format entirely, while every signature stays fully offline.

New

Faster scanning

The animated QR now runs a compact, redundant loop instead of an endless stream: fewer frames on screen, quicker scans in both directions.

New

New tokens

The full Polygon token set — USDC, USDT0, WETH, WBTC, DAI, AAVE, LINK, UNI and more — plus PAXG and AMP on Ethereum, and USDT on MultiversX.

New

Account-closing safety

XRP AccountDelete and Stellar Account Merge now show a clear Full Balance warning before you sign.

New

Fingerprint performance

Faster, more reliable biometrics for unlocking your device and signing transactions.

Improved

Asset list cleanup

Over 100 inactive, duplicated and legacy tokens removed. BNB Beacon Chain and Groestlcoin (GRS) are no longer supported — BNB on BNB Smart Chain is unaffected.

Improved

Stability & performance

Clearer scan error messages, a redesigned confirmation screen, and general work across the OS — the quiet half of a foundational release.
