Learn about the wallet options available on Borrow by Sats Terminal, including the built-in Privy smart wallet, external wallet connections, and how self-custodial access keeps your funds secure.

What Wallets Does Borrow Support?

Borrow by Sats Terminal makes it easy to start borrowing stablecoins against your Bitcoin -- and a big part of that simplicity is wallet access. You do not need to spend hours setting up a complicated digital wallet before you can explore lending rates. Borrow gives you a built-in wallet the moment you create an account, while also letting advanced users connect external wallets they already own.

This guide walks through every wallet option available on Borrow, explains how the embedded Privy wallet works, and answers the most common questions about wallet security and cross-chain compatibility.

The Built-In Privy Embedded Wallet

When you sign up for Borrow, a self-custodial smart wallet is created for you automatically via Privy. This is the fastest way to get started because there is nothing to install, no seed phrase to write down on paper, and no browser extension to configure.

How It Works

Privy uses a technology called multi-party computation (MPC). Instead of storing your private key in a single place -- which would be a security risk -- the key is split into encrypted shares distributed across separate secure environments. When you need to sign a transaction, the shares work together without ever reassembling the full key in one location.

You authenticate using familiar methods:

  • Email -- sign in with a one-time code sent to your inbox.
  • Social login -- use Google, Apple, or other supported identity providers.
  • Phone number -- receive an SMS verification code.

Even though the login feels simple, the wallet behind it is a real on-chain wallet with its own address. You can send funds to it, receive funds from it, and interact with smart contracts on every blockchain Borrow supports.

Why an Embedded Wallet Matters

Traditional DeFi platforms require you to install MetaMask or a similar extension, write down a 12- or 24-word seed phrase, fund the wallet with a native gas token, and manually switch between networks. Each of those steps is a friction point where new users drop off or make costly mistakes.

Borrow removes those hurdles:

  1. No seed phrase -- MPC key sharding replaces the seed phrase model.
  2. No gas management -- Borrow handles gas fees behind the scenes.
  3. No network switching -- the platform routes transactions to the correct blockchain automatically.
  4. Instant setup -- your wallet is ready in seconds, not minutes.

This approach opens Bitcoin-backed lending to people who have never used a digital wallet before, while still providing the self-custody guarantees that experienced crypto users expect.

Connecting an External Wallet

If you already have a wallet you trust, Borrow lets you connect it instead of -- or in addition to -- the embedded Privy wallet.

How to Connect

  1. Click Connect Wallet on the Borrow homepage.
  2. Choose your wallet provider from the list.
  3. Approve the connection request in your wallet app or extension.
  4. Your wallet address appears in the Borrow dashboard, and you can immediately browse lending offers.

The process takes under 30 seconds for most wallets. Once connected, Borrow reads your on-chain balances and shows you the best available lending rates for the collateral you hold.

Using a Hardware Wallet

Hardware wallets like Ledger and Trezor provide the highest level of security because your private key never leaves the physical device. You can use these with Borrow by connecting through MetaMask's hardware wallet integration or through WalletConnect.

The trade-off is convenience: you need the physical device every time you sign a transaction. For large positions, many users prefer this extra security layer. For smaller or more frequent transactions, the embedded Privy wallet offers a faster experience.

Wallet Security on Borrow

Regardless of which wallet option you choose, Borrow is designed around the principle of self-custody. Here is what that means in practice:

  • Borrow never holds your private keys. Whether you use the Privy wallet or an external wallet, only you can authorize transactions.
  • No withdrawal permissions. Borrow cannot move your funds without your explicit approval of each transaction.
  • Smart contract interactions are transparent. Every lending action routes through audited protocols like Aave v3 and Morpho Blue. You can verify every transaction on a block explorer.

Common Security Best Practices

  • Enable two-factor authentication on your email or social login used with Privy.
  • Bookmark the Borrow URL to avoid phishing sites.
  • Review transaction details before confirming -- check the recipient address and amount.
  • Start small. If you are new to crypto lending, begin with a small amount to get comfortable with the process before committing larger sums.

Multi-Chain Wallet Support

Borrow operates across Ethereum, BASE, Arbitrum, Polygon, Optimism, and BSC. Your wallet works seamlessly on all of these networks.

How Cross-Chain Access Works

With a traditional wallet setup, you would need to:

  1. Add each network to MetaMask manually.
  2. Fund each network with its native gas token (ETH, MATIC, BNB, etc.).
  3. Switch networks every time you want to interact with a different chain.

Borrow eliminates all of that. The platform detects which blockchain offers the best rate for your loan, handles any necessary bridging of assets, and executes the transaction on the correct chain. Your single wallet address is all you need.

This is especially valuable when you are comparing offers across protocols. A lending rate on Aave v3 (Arbitrum) might be lower than the same offer on Ethereum mainnet. Borrow surfaces both options and handles the routing, so you always get the best deal without any manual network gymnastics.

Common Questions

You do not need to bring an external wallet. When you sign up for Borrow, a Privy-powered embedded smart wallet is automatically created for you. This wallet is self-custodial, meaning only you control the private keys. You can also connect popular external wallets like MetaMask, Coinbase Wallet, or WalletConnect-compatible wallets if you prefer.
