We covered what a wallet in general looks like in the Accessing Wallets section and then what a wallet connector looks like in the Interacting With Wallets section. However, the wallet connector for Bitcoin wallets is a bit different from the EVM wallets, so we will cover that separately here. This is because Bitcoin wallets have different capabilities and requirements. For example, Bitcoin wallets can have multiple addresses associated with them, like payment and ordinal addresses.

Checking if a wallet is a Bitcoin wallet

  • React
  • JavaScript
  import { isBitcoinWallet } from '@dynamic-labs/bitcoin';

  if (!isBitcoinWallet(wallet)) {
    throw new Error('This wallet is not a Bitcoin wallet');
  }

  const result = await wallet.sendBitcoin({
    amount: 100000000n,
    recipientAddress: 'SOME-ADDRESS',
  });

What is a satoshi?

This smallest unit allows for transactions involving very small amounts of bitcoin, facilitating microtransactions and improving the granularity of payments in the Bitcoin network. 
1 Bitcoin = 100,000,000 Satoshis

​
What is a PSBT?

A partially signed bitcoin transaction (PSBT) is a standard for transactions that have not fully signed. This allows different participants with different keys/signers to sign a transaction without revealing their private keys to others. Multi-sig wallets utilize these. This allows for a multi-step transaction process which is both safer and more efficient.

Examples

We’ve included a few examples of how to use the Bitcoin wallet connector in this section:
