Interlay v2 Whitepaper: From Bridge to BTC DeFi Hub

We are excited to share with you the long-awaited whitepaper outlining our vision for the future of Bitcoin in the rapidly growing DeFi space. As you know, Interlay has been working hard to bridge the gap between Bitcoin and DeFi, and now we are ready to take the next big step: native support for decentralized financial tools tailored to Bitcoin.

We have outlined our plans in detail in our v2 whitepaper. We believe that our vision for native support of decentralized financial tools tailored to Bitcoin has the potential to unlock a whole new world of financial possibilities, bringing Bitcoin closer to its original vision of a decentralized, transparent, and censorship-resistant financial system.

A first, alpha version of the DeFi Hub is already live on testnet.

We invite you to read the whitepaper and share your thoughts, ideas, and suggestions — and ultimately vote on the suggested course of action. Your voice as a community as always defines the next steps for Interlay — and in this case, for the future of Bitcoin DeFi.

New Features

USDT as Vault collateral on Interlay and Kintsugi

Interlay and Kintsugi now allow Vaults to use USDT as collateral for their operations, allowing them to spread their risk between more assets and enjoy the ease of measuring risk against USD. By adding stablecoin collateral, they can take advantage of reduced volatility and a more predictable risk profile.


DIA x Interlay: iBTC collateral-proofing price feeds

Interlay and Kintsugi have partnered with DIA to add iBTC and kBTC collateral proofing to their data feeds: DIA will be monitoring the iBTC collateralization rate, making sure dapps can rely on the bridge security. This integration adds an extra pair of eyes to the iBTC bridge — a testament to Interlay and DIA’s shared values and commitment promote transparency in the crypto ecosystem.


Recommendations for Kintsugi’s DeFi-Hub Launch

Interlay is inviting its community to discuss the recommendation to launch its DEX and lending protocols on Kintsugi in February/March 2023. The recommendation includes details on the suggested DEX pools and lending markets. The community’s participation and feedback are crucial to the success of this project, so we encourage everyone to review the discussion post and contribute.

[Referendum] Prevent submission of proposals without a preimage

The Kintsugi chain allows the submission of proposals without noting the preimage. This is outdated and should not be done. A runtime upgrade should fix this.

[Referendum] Register SKSM as a foreign asset

We would like to register sKSM on Kintsugi as a first step towards the Kintsugi DeFi Hub launch.

[Proposal] Upgrade to runtime 1.21.10: Capacity-based vault revenue distribution

This proposal:

  1. Adds the capacity-based vault revenue distribution as outlined in https://interlay.subsquare.io/post/13
  2. Updates the Polkadot dependencies to v0.9.37

Updates Kintsugi to the latest runtime (breaking).

[Referendum] Interlay Grants Program — Milestone Payment 1 for RFP: Analytic Dashboard for Lending Market

The Interlay Grants Program is moving full steam ahead and we need your participation through governance:


Advancing Bitcoin

Interlay co-founder Alexei Zamyatin will be in London on March 2nd speaking at Advancing Bitcoin. His presentation is titled “Bitcoin Bridges: Cure or Curse?”. Alexei will talk about how the demand for Bitcoin on other chains has increased since the release of the “Bitcoin sidechains” paper 8 years ago, with around 400k BTC bridged to other chains at the peak of the recent bull run. However, the majority of these bridges are centralized and may pose risks for users, as demonstrated by the recent depegging of SolanaBTC and the hasty shutdown of RenBTC.
