Understanding Bitcoin Covenants and What They Change for BitVM Bridges
A covenant is a Bitcoin script capability that restricts how a coin can be spent in the future: not just who can spend it, but what the spending transaction must look like.
A BOB guide describes its use of BitVM technology to create trustless bridges between BOB, Bitcoin, and Ethereum, noting that the BitVM Bridge is preparing for mainnet launch.

What Is BOB (Build on Bitcoin)? A Complete Guide to Bitcoin's Hybrid Layer 2
The BitVM bridge is central to BOB's plans for trustless Bitcoin transactions. This native BTC bridge, powered by BitVM technology, is designed to enable BTC transfers in a trustless, non-custodial manner without wrapping BTC. It is currently being tested on testnets with partners such as Anchorage and RockawayX, with a full-scale production launch planned for early 2026.
A new article examines how Bitcoin's Taproot upgrade enabled BitVM, and traces how it underpinned Citrea's launch of a ZK-rollup settling directly on Bitcoin.

Taproot's Second Act: How BitVM and Citrea Built Bitcoin Rollups
When Bitcoin activated Taproot in November 2021, the sales pitch was modest. Schnorr signatures would make multisignature spends look like ordinary single-key payments, complicated spending conditions would hide inside a Merkle tree until the moment they were used, and the average transaction would get a little cheaper.
