What it does
80+ chains, one recovery phrase
58 Ethereum-style networks, Bitcoin-family coins and more. Every account comes from the one recovery phrase you created on your device, and your keys never leave it.
Hardware-wallet approval
Approve any account’s transactions on a hardware wallet, a physical device that keeps your keys offline. USB on desktop, Bluetooth on mobile.
Every OmniBazaar market
Swap, trade, predictions, marketplace and NFTs all work right in the extension, on the same design as the web app: we never hold your money.
No network fees on OmniCoin
You approve the transaction. Our validators, the computers that run the network, then deliver it and pay its fee. Your cost is always $0.00.
Privacy on demand
Make a balance private with one click, and public again whenever you choose.
NFTs & cross-chain moves
See your NFTs from every chain in one place, and move coins between blockchains from the same screen.
Web, extension and mobile stay aligned
A hard rule here: nothing ships in one app until it ships in all three. The web app, this extension and the Android app are the same product, with the same we-never-hold-your-money protections.
