## What is One&One?

One&One is a simple and secure self-custody digital wallet that allows users to create or import their own blockchain wallets and securely manage their digital assets.

One&One is designed solely as a self-custody wallet application. Users always maintain full control of their private keys, recovery phrases, and wallet data. The developer never has access to users' wallets, private keys, digital assets, or funds.

With One&One, users can:

• Create a new wallet
• Import an existing wallet using their own recovery phrase or private key
• Securely store supported blockchain assets
• Send digital assets to another blockchain wallet address
• Receive digital assets from another blockchain wallet address
• View wallet balances and transaction history
• Manage multiple self-custody wallets from a simple and intuitive interface

One&One does not provide any cryptocurrency exchange functionality.

The app cannot buy, sell, swap, convert, or exchange any cryptocurrency.

The app does not offer:

• Cryptocurrency exchange, including CEX or DEX
• Token swap services
• Buying or selling cryptocurrency
• OTC trading
• Brokerage services
• Exchange APIs
• Investment products
• Staking
• Lending
• Yield generation
• Custodial wallet services
• Financial advisory services

The app does not connect to any cryptocurrency exchange, trading platform, swap protocol, or exchange API.

One&One simply allows users to securely store, send, receive, and manage blockchain assets that they already own using their own self-custody wallets.

Your wallet.
Your keys.
Your control.
