OPEQ USB 1.6.0 (beta)

What changed in 1.6.0:

• New design. Your balance sits on a circuit-board card with a meter that shows how many one-time quantum keys are left. Send, Receive, Swap and Bridge are one tap away under the card, and everything else lives in the settings menu.
• Network picker on the card. Tap the network name on the card to switch between Solana, Ethereum, Base, Arbitrum, Robinhood Chain and Elysium.
• Clearer errors. If the wallet cannot reach the network, it says so on the main screen with a Try again button, and the actions stay off until your balance has loaded.
• The OPEQ window now opens at phone width.
• No change to signing, keys or the on-chain programs.

Upgrading from 1.5.0 or earlier: replace everything in the OPEQ-USB folder on the stick except the data folder. Your wallet stays in data.

OPEQ, the quantum-resistant wallet for Solana and EVM networks, running straight from a USB stick on Windows. Nothing is installed: double-click OPEQ on the stick and the wallet opens in its own Chrome or Edge window. The wallet lives in the data folder on the stick, not on the computer.

Beta. The planned external audits have not happened yet. Keep small amounts.

Use it

1. Download OPEQ-USB.zip, right-click it and choose Extract All.
2. Copy the OPEQ-USB folder to your USB stick.
3. Double-click OPEQ on the stick. If Windows asks whether to run it, choose Run.
4. Create a wallet or recover one from its 24 words, then activate it once with at least 0.01 SOL.

Needs Windows with Google Chrome or Microsoft Edge (version 137 or later).

Keep it safe

• Only plug the stick into computers you trust. A computer with malware can change the files on the stick. OPEQ checks its files against https://opeq.io/usb/1.6.0.json at every start and refuses to open if they differ, but a careful attacker could change that check too. A stick with a write-protect switch is best.
• Your 24 words are the only backup. Never copy the data folder to a second place: two copies can reuse a one-time key.
• When you sign, the key is open on that computer for a few seconds.

OPEQ USB 1.5.0 (beta)

What changed in 1.5.0:

• Elysium. Kinetiq's new network (chain 99901) joins Ethereum, Base, Arbitrum and Robinhood Chain. Your OPEQ account has the same address there, protected by the same hash-based signatures. Network fees are paid in HYPE.
• Bridge to Elysium. HYPE comes in from Solana, Ethereum, Base and Arbitrum, and USDC moves in and out. Relay routes HYPE through USDC on Elysium, so if a HYPE delivery fails, the refund arrives as USDC at your own Elysium address. The wallet checks that before you sign.
• No Swap on Elysium yet: Uniswap is not deployed there.

Upgrading from 1.4.1 or earlier: replace everything in the OPEQ-USB folder on the stick except the data folder. Your wallet stays in data.

OPEQ USB 1.4.1 (beta)

What changed in 1.4.1:

• EVM networks look like Solana now. Balance and address on the chip, and Send, Receive, Swap, Bridge, Tokens, Keys and Multisig in tabs. The gas key moves to Keys once your account is set up and funded.
• Swap on Robinhood Chain. Robinhood Chain has no USDC, so the pinned stablecoin there is USDG (Global Dollar, issued by Paxos). ETH to USDG and back works through Uniswap like USDC on the other networks.
• Balance and Max under every amount. Send, Swap, Bridge and Tokens show what you hold of the coin you pay with, and Max fills it in. On Solana, Max keeps 0.01 SOL for network fees. USDC (USDG on Robinhood Chain) now shows in the EVM Tokens and Send lists without adding it.
• Success messages clear by themselves after 20 seconds, a finished bridge clears its status, long transaction ids wrap instead of running off the screen, and the network menu says Robinhood.

OPEQ USB 1.4.0 (beta)

What changed in 1.4.0:

• Swap on EVM networks (beta). The new Swap card on Ethereum, Base, Arbitrum and Robinhood Chain swaps ETH, USDC and tokens you added through Uniswap. OPEQ takes no fee.
• The wallet gets the price from Uniswap's own contracts on two independent network sources and refuses if they disagree, builds the swap itself, and test-runs it as your account before you sign and again right after you confirm. If less than the minimum would arrive, nothing is signed; if Uniswap would pay out less than the minimum on chain, the whole swap is undone.
• Two rounds of internal attack reviews and a real swap on Base mainnet. No external audit yet, so start with small amounts.

OPEQ USB 1.3.0 (beta)

What changed in 1.3.0:

• Bridge (beta). Move SOL, ETH and USDC between Solana and Ethereum, Base, Arbitrum and Robinhood Chain from inside the wallet: the Bridge tab on Solana and the Bridge card on each EVM network. Funds always go to your own OPEQ address on the other network. The bridge is run by Relay; OPEQ takes no fee.
• The wallet builds the deposit itself and checks Relay's order before you sign: receiver, refunds, amounts, slippage, deadline, no extra fees and no extra calls. The deposit carries your quantum-resistant signature; Relay's delivery on the other network is not quantum-resistant, so you rely on Relay until it arrives, usually within seconds.
• Tested on mainnet in both directions. Internal reviews only, so start with small amounts.

OPEQ USB 1.2.0 (beta)

What changed in 1.2.0:

• Multisig (beta). Create a shared account that several OPEQ wallets control together, on Solana and on the EVM networks. Moving funds needs the number of approvals you choose, and every approval is a quantum-resistant signature from each owner's own wallet. It is optional: your normal wallet works exactly as before. Open the Multisig tab to start.
• The multisig had several rounds of internal attack reviews and was tested on mainnet with small amounts. No external audit yet, so start with small amounts.
• The Solana multisig program can still be upgraded by the OPEQ admin wallet during the beta; it will be locked after the external audit.

OPEQ USB 1.1.0 (beta)

What changed in 1.1.0:

• EVM networks (beta). The same 24 words now also give you a quantum-resistant account on Ethereum, Base, Arbitrum and Robinhood Chain. Pick the network at the top of the wallet. The EVM contracts have had four internal security reviews but no external audit yet, so start with small amounts.
• Stricter file check. If any file on the stick differs from this release, OPEQ now refuses to open the wallet at all and shows only a warning page listing the files.
• Update notice. From this version on, the stick tells you at start when a newer release exists.
• Fixes from four rounds of internal review.

OPEQ USB 1.0.1 (beta)

What changed in 1.0.1: on Windows 11 the PowerShell window behind OPEQ stayed open, and closing it left a black wallet window. It now runs out of sight, and the wallet window closes by itself if OPEQ stops. If you have 1.0.0, replace everything on the stick except the data folder.
