Self-custody key management infrastructure for high-performance, security-critical use cases. Securing billions for top Web3 teams.

Most policy engines assume the world is simple: set a spend limit, add an approver, allowlist a few addresses. But the real world isn’t simple. Signing logic often depends on conditions outside the key manager itself: 🔍 Did this burn actually finalize on another chain? 🔍 Does

Too many hacks start with a bad deployment, not bad code. At DSS, @deiandelmars of @cubistdev will teach how to prevent them with programmable key management. Participants will write policies that enforce verified upgrades, multi-party approvals, and secure keys across chains.

这不是一次单纯的收购，而是比特币DEFI和多链生态的重大进步. 比特币市值超$2.1万亿，但大多数人不知道其不到1%活跃于on chain DeFi.Lombard接管升级BTC.b，意味着能填补其核心问题：缺乏去中心化、安全的桥接资产. Lombard 从Ava Labs手中接管$538M规模BTC.b基础设施有着非凡的意义：
BTC.b goes cross-chain. @Lombard_Finance unveiled BTC.b’s new permissionless architecture after acquiring its infra from @avax. It’s built to scale BTC.b securely across chains using Cubist’s authenticated deposits, HSM-backed keys, governance policies, and bridge accounting.

This deal shows maturity in crypto. Ava Labs and Lombard prove collaboration > competition: ✅Avalanche keeps liquidity; Lombard scales infrastructure. ✅Both ecosystems grow stronger https://t.co/L25cjdiD8L
As @avax’s Bitcoin bridge moves to @Lombard_Finance, BTC.b expands its reach. Cubist’s CubeSigner and Bascule Drawbridge will play key roles in the bridge’s trust-minimized, multi-layered security model—powering key management, minting, and withdrawal operations.

The wrapped BTC model centralizes Bitcoin liquidity around a few custodians. Cubist tech enables permissionless assets secured by code, not trusted parties, so DeFi users can own, verify, and govern value directly.
BTC.b Distribution is one of the main reasons for the acquisition. Avalanche held 5,000 BTC, of which almost 80% is actively used in DeFi. The majority of this—59% - is held on Aave, further confirming the use case of BTC as a collateral. Interestingly, the DeFi Utilization

And the security layer for this "foundation for real bitcoin capital markets" runs on @cubistdev's HSM-backed key management and Bascule Drawbridge technologies.
So @Lombard_Finance just scooped btc.b, the bitcoin asset running laps on avalanche with over $538M floating around. They’re taking what already works and turning it into the foundation for real bitcoin capital markets. @Lombard_Finance playing long-term games only

I’ve been impressed with Lombard’s execution post-TGE. Most teams spend quarters figuring out their narrative; @Lombard_Finance has spent that time expanding its moat. The acquisition of $BTC.b from Ava Labs isn’t just another bridge deal. It’s a foundational realignment for BTC

Big moves in Japan: TIS’ Multi-Token Platform is bringing onchain finance to major banks and corporations. Proud to collaborate alongside @AvaCloud on what’s shaping up to be a defining moment for digital finance 👀
Hi Wall St 👋 Japan’s financial backbone is moving onchain with @AvaCloud on @avax. Even @YahooFinance had to cover it. 🔺 https://t.co/Syn9PtVUSn

Bitcoin is enduring as a lasting store of value. Soon every market will be onchain. At Cubist, we’re focused on the programmable security layer for Bitcoin’s obvious future. Proud to be building BTCfi with @SuiNetwork.
On October 31, 2008, the Bitcoin whitepaper introduced a new financial era. Today, the story continues with BTCfi - the evolution that unlocks Bitcoin’s full potential through real utility and composability. Happy Orange Holiday 🧡

Smart strategy by @AvaLabs to focus on the Avalanche core while transitioning BTC.b operations and growth to @Lombard_Finance. Running secure bridges is complex, and Lombard's model scales it—anchored in the verifiable foundation we built CubeSigner and Bascule to support.
The most important thing to understand from this $500M+ asset acquisition is one thing — it makes no sense for any chain, app, protocol, custodian, fintech etc to launch their own Bitcoin wrapper. For @Lombard_Finance, the additional TVL is great, the CT chatter is great, but

“Lombard + BTC.b will make BTC in DeFi better than BTC on CEXs.” Hard to argue when the new bridge design rivals institutional systems, but without the centralized control. We built CubeSigner and Bascule for exactly this: to bring TradFi rigor to the openness of onchain.
I think this is a new DeFi First? $500mn+ asset acquisition Here's the gist of it: BTC onchain is broken. Users want the real thing — not branded wrappers, high mint/redeem fees, and gated access. At best, your current BTC wrapper is a 3rd or 4th priority for the team

For the first time, the infrastructure of a live onchain asset has been acquired. BTC.b's transition to @Lombard_Finance introduces a new bridge architecture built on Cubist's programmable security infrastructure for cross-chain expansion and scale.
@chainlink BTC.b has been live since 2022 with ~$538M currently in circulation and deep integrations across Aave, BENQI, and LFJ. Learn more about how the transition will work: https://t.co/Wx8xViiUqP

BTC.b’s transition shows how ecosystems scale sustainably. This is a blueprint for growth. We’re proud to have Cubist key management and bridge verification infrastructure helping @Lombard_Finance provide institutional-grade security to BTC.b without institutional gatekeepers.
