sBTC Developer Release is Here

Week of October 20, 2023

Gm Bitcoiners,

Hello from London! This week, I’m excited to share that the sBTC Developer Release has been deployed on Stacks devnet. This week’s issue will go over the main things you need to know to get up to speed on this milestone.

💻 What is the sBTC Developer Release?

The sBTC Developer Release is a minimum-viable testnet deployment of sBTC. It will allow the sBTC working group to test deposits and withdrawals, without the complexity of a decentralized set of signers. Instead, this release uses a central coordinator, which has two primary functions: (1) mint and burn sBTC (2) fulfill peg-out requests.

👩‍💻 Who is this release for?

As its named, this release is primarily for Bitcoin developers to begin building applications that will utilize sBTC. Over the past few weeks, the testing group has onboarded 150 qualified developers for the testing program. We’re seeking contributors to help catch bugs and provide invaluable feedback to the working group.

🔎 What is included in this release?

  • End-to-end deposit and withdrawal flows

  • SDK and CLI to interact with the protocol

  • Bridge API and Web Application

To get started, here is a tutorial of a demo application that uses the Bridge API. Kudos to Kenny Rogers for creating this overview guide! For more detailed documentation, check out this developer guide.


Tweets of the Week

Copper becomes the first major custodian and digital asset infrastructure provider to signal their intent to support the expected Nakamoto and sBTC upgrades. Their announcement is a must-read for any Bitcoin builder (especially those of you keen on sBTC) and covers their integration with the Stacks, bringing Stacking, custody, and SIP-010 support to the network.

(Shameless plug) The Bitcoin Layer 2 thesis is gaining speed. This is one of the most exciting things to be working on in the industry and I’ve summarized a few of my thoughts on the opportunity below.

The BitVM whitepaper got a lot of coverage last week and it has the potential to bring more expressivity to Bitcoin. Check out this take from Muneeb on how it impacts Stacks. (Hint: it’s a good thing)
