Use MetaMask to Inscribe and Transfer Ordinals, and Transfer BTC

This example demonstrates how users can use a single web wallet to manage assets on both Bitcoin and BOB. The BOB MetaMask Snap can be used to inscribe and transfer ordinals, and transfer BTC, using only MetaMask as well as access any other EVM functions on BOB.

Example Code

You can find the code for this example on our GitHub repository.

Demo​

We have created a testnet demo of the application at https://ordinals.gobob.xyz, allowing anyone to inscribe, view and transfer ordinals, and transfer BTC.

MetaMask Snap

This demo uses MetaMask Snaps. MetaMask Snaps are not currently supported on mobile wallets, so this demo will only run in the desktop version of Chrome or Firefox.

Creating a test profile​

We recommend creating two test profiles so that you can test transferring Ordinals and BTC between two accounts.

Installing the MetaMask Snap​

Click the 'Connect Wallet' button on https://ordinals.gobob.xyz. MetaMask will prompt you to install the Snap, and give it permissions.

Take note that your BTC wallet in the Snap derives its private keys from your MetaMask wallet's seed phrase.

Funding your account​

One you have connected your wallet, you will see your derived BTC address in place of the 'Connect Wallet' button. Click on the address to copy it to the clipboard and then fund it using a BTC faucet:

You can check your BTC balance by clicking on the 'Transfer BTC' button.

note

BTC may show in your balance before it is confirmed. If you try to use the application before the funds are confirmed, your balance will be too low and you may see errors.

  • Click on the 'Inscribe Ordinal' button, and then the 'Text' tab.
