Building Native Bitcoin Rollups: dWallet and Avail Revolutionize without Bridges or Wrapping

Bitcoin users will soon have access to smart contract functionality without the need to bridge, wrap, or give up control of their BTC. This is thanks to a new integration between dWallet Network and Avail. Through this partnership, dWallet’s smart contracts, built on Avail’s data availability solution, can create Bitcoin signatures while still allowing users to maintain complete control of their BTC. Unlike existing cross-chain solutions, which require users to sacrifice ownership of their BTC, this integration ensures that user ownership is not transferred, reducing the risk of collusion or hacking.

The Bitcoin community has been critical of Bitcoin rollups or “layer-2s”, as many of these solutions have been accused of engaging in “affinity scamming” by tricking users into bridging or wrapping BTC in exchange for other tokens. To address these concerns, dWallet has partnered with Avail to create programmable native BTC. By utilizing multi-party computation (MPC), a wallet operating on the decentralized MPC dWallet Network can generate a Bitcoin transaction. The user’s participation in the process guarantees the security of their assets, as no one can collude or hack and steal them.

This collaboration aims to expand Bitcoin’s capabilities by enabling the creation of native rollups through dWallet’s MPC infrastructure. This means that smart contracts can run any logic and utilize native BTC without the need for bridging or wrapping tokens. This opens up possibilities for DeFi protocols, such as swapping, lending, and staking, to use native BTC. It also allows for other use cases, such as DAOs controlling native BTC, trading portfolios of ordinals, and gaming with native BTC.

Anurag Arjun, co-founder of Avail, believes that this trust-minimized approach to using BTC programmatically on other blockchains is a novel way to drive Bitcoin adoption. He sees Bitcoin as a solid base layer with the highest security in the ecosystem. The dWallet technology, which allows Solidity smart contracts on an Avail rollup to create Bitcoin signatures, provides developers with the tools to manage a dWallet. The dWallet Network requires approval from the Avail rollup smart contract for logic enforcement, ensuring that users finalize the signature to prevent collusion and asset theft.
