Zabo is an API enabling developers to connect their users' cryptocurrency wallets and facilitate transactions.

You can use Zabo to do interesting things like:

  • Connect self-custody (MetaMask, Ledger, etc.) and custodial wallets (Coinbase, Gemini, exchanges)
  • Perform ETH, ERC20 and BTC transfers all within the same API / application
  • Retrieve balances, transaction history, wallet addresses and more from connected wallets

Whether your user connects a Ledger with BTC, MetaMask with ETH, or a Coinbase custodial wallet with BCH - Zabo let's you handle it all. Zabo works in both centralized and decentralized contexts, connects both custodial and non-custodial wallets, and operates in the browser only or server environments.

Some concrete use cases you can build with Zabo include:

  • Connect Bitcoin wallets and exchange accounts to your DeFi application (in addition to Ethereum ones). Send and receive BTC too (in addition to ETH/ERC20)!
  • Creating a complete picture of net worth by connecting wallets and displaying balances (personal financial tracking, investments, wealth management)
  • Onboarding / funding experiences - connecting external wallets and transferring in funds (fundraising, funds onboarding). Or do the reverse - funding external accounts connected to your application.
  • Authenticate wallet ownership and analyze balances / transaction history (lending, crypto-credit scoring, compliance)
  • Send ETH, BTC or ERC2o based on conditions (payments, rewards)

Whether your user connects a Ledger with BTC, MetaMask with ETH, or a Coinbase custodial wallet with any asset they support - Zabo lets you handle it all. Zabo works in both centralized and decentralized contexts, connects both custodial and non-custodial wallets, and operates in the browser only or server environments.
