OB Wallet: USDT & Crypto

Metaverse Trading Ltd

About this app

Got USDT on Tron but no TRX for the network fee? OB Wallet still sends it: the fee can be paid in USDT, and you see exactly how much before you confirm. This is an optional paid service.

OB Wallet is a self-custody wallet for USDT, Bitcoin, Ethereum, Tron, Solana, TON and popular EVM networks. There is no account and no sign-up: your wallet is a 12-word recovery phrase that you write down, and the key that protects it on the phone is created inside the phone's secure hardware.

ONE APP, THREE WALLETS
• Daily: send, receive and pay; buy crypto with your own card through licensed payment partners (optional; you choose the offer, and payment happens in your browser)
• Cold: a separate wallet for the savings you keep and do not spend
• Company: take payments for your business, small or large; pair it with a payment panel you already use and approve its requests on the phone (the panel never gets your keys)
• Each wallet has its own recovery phrase. We cannot freeze your wallet or move your money: there is no account to close, and only your phone signs.

MADE FOR USDT
• Send USDT on Tron even when you hold no TRX: the fee can be paid in USDT (optional, paid; the fee is shown before you confirm)
• Hold some TRX? An optional paid reduced fee for sending USDT on Tron, usually lower than the normal network fee (the fee is shown before you confirm)
• A warning before you send to a look-alike address, a common trick that empties wallets, or to an address the token issuer has frozen
• Tiny "dust" transfers that scammers send to plant fake addresses in your history are kept out of your list
• USDT on Tron, Ethereum, Polygon, Solana and TON, side by side

YOUR KEYS STAY ON YOUR PHONE
• The recovery phrase is stored sealed. The key that unseals it is generated in Android Keystore (StrongBox where the phone has it) and never leaves it.
• Opening the wallet takes your screen lock and a PIN you choose.
• Transactions are signed on the phone; your private keys and recovery phrase never leave it.
• Screens that show your wallet are protected from screenshots and screen recording.

NETWORKS AND ASSETS
• Bitcoin, with native SegWit and Taproot addresses
• Ethereum, Polygon, Arbitrum, Base, OP Mainnet and Avalanche, all on one address
• Tron
• Solana (SOL, USDT, USDC)
• TON (GRAM, formerly TON; USDT)
• USDT, USDC and other tokens, with discovery of the tokens you already hold

EVERYDAY USE
• Send and receive with QR codes
• Save the people you pay, and see the network fee before you confirm
• Swap between assets, on one network or across networks, through third-party swap providers (the fee is shown before you confirm)
• Live prices and the total value of your wallet
• The app in English, Português, Español, Tiếng Việt, Bahasa Indonesia, ไทย, Українська, हिन्दी, العربية, اردو, Türkçe, Azərbaycan, Русский, Oʻzbekcha and Кыргызча

A BACKUP THAT FITS YOUR LIFE
• Restore any time from your 12-word phrase; an optional passphrase is supported
• Split the backup into cards: any two of three recover the wallet, and one card alone reveals nothing

PRIVACY
• The app never asks for your name, email or phone number
• No analytics, no advertising, no crash reporting
• The blockchain data providers are listed in settings, and you can point the wallet at your own node

PLEASE NOTE
OB Wallet cannot recover your funds for you. If you lose both your recovery phrase and your phone, nobody, including us, can restore access. Write the phrase down and keep it offline.

What’s new

Buying crypto now shows the price in your country's money and asks how you will pay. Beside the card, the local ways offered where you are are listed, such as bank transfer, PIX, SEPA, SPEI, M-Pesa or P2P, each with how much you would get and how fast it is. The offers then follow the way you pick. After typing the amount you can switch between your money and US dollars, and change the coin without leaving the purchase.
