Ember Protocol Launches New Vault with tBTC as First Bitcoin Collateral

Ember Protocol has launched its new vault on Sui, introducing a streamlined way for users to access structured yield strategies. This development strengthens Sui’s DeFi landscape, expanding the tools available to participants who want to deploy capital efficiently in a secure and transparent environment.

At the core of this launch is the decision to make tBTC the first Bitcoin available as collateral within Ember’s vault. This integration not only underscores Ember’s commitment to building with reliable, composable assets but also highlights the growing role of tBTC as essential infrastructure for Bitcoin in decentralized finance.

Unlocking tBTC Structured Yield on Sui

The Ember Bitcoin Vault marks an important milestone for Ember Protocol on Sui. Built to make advanced DeFi strategies more accessible, the vault abstracts away complexity while offering users new ways to optimize their capital. For participants on Sui, this means engaging with sophisticated yield products without the need to manually manage multiple steps or strategies.

For users, this means the ability to unlock structured yield strategies on Sui without giving up their Bitcoin position.

Within just two days of launch, the vault has already attracted $2.53M in deposits, targeting an APY of 11.27%.

The strategy allocates funds across Bluefin ecosystem:

• 60% supplied to Bluefin Lend
• 20% borrowed for capital efficiency
• 20% deployed into Bluefin’s AMM auto-LP

...combining lending, borrowing, and liquidity provision into one optimized yield engine. (Important note: this strategy updates daily)

tBTC as the First Bitcoin Collateral

Threshold’s tBTC is now the first form of Bitcoin collateral available in Ember’s vault. As a decentralized, 1:1 BTC-backed asset, tBTC allows users to hold exposure to Bitcoin while participating in DeFi protocols. This makes Bitcoin not only a store of value but also productive capital.

From a protocol perspective, Ember’s decision to accept tBTC is a signal of confidence. It recognizes the asset’s decentralization, collateral efficiency, and growing liquidity footprint across multiple chains. With every integration like this, tBTC strengthens its role as the most DeFi-capable representation of Bitcoin onchain.

Why This Matters

• For Ember Protocol: The vault represents a significant step in expanding its product suite. Accepting tBTC as collateral ensures that Ember can attract a broader base of users, including Bitcoin holders who want access to yield without leaving the asset behind.
• For tBTC: Being chosen as the first collateral asset is a milestone that reinforces its credibility. Each integration confirms its reliability and deepens its utility across the multi-chain DeFi landscape.
• For Sui: This integration expands Sui’s access to Bitcoin, bridging its ecosystem with the most significant asset in crypto markets. It increases liquidity potential, strengthens DeFi infrastructure, and creates momentum for additional adoption.

Building on Momentum

“The launch of Ember’s new vault is an exciting step for Sui’s DeFi ecosystem. tBTC being accepted as its first Bitcoin collateral is a strong signal of its growing role in DeFi, and we’re happy to support this milestone.” - Maclane Wilkinson, Co-Founder, Threshold Network

The launch of Ember’s vault with tBTC collateral is just the beginning. As more protocols on Sui and beyond adopt tBTC, the asset’s utility will continue to compound. Users can expect additional integrations that allow Bitcoin to flow seamlessly into structured products, lending markets, and other yield strategies.

tBTC is designed to expand Bitcoin liquidity across multiple networks, making BTC truly composable in DeFi. As part of its mission to deepen adoption, Threshold is doubling down on Sui, with the Ember Bitcoin Vault launch serving as a cornerstone of the Sui x tBTC Phase 2 campaign. Users can now also bridge tBTC from Ethereum to Sui via https://sui.threshold.network, further unlocking liquidity and strengthening Sui’s growing BitcoinFi ecosystem.

For Threshold Network, this milestone is part of a broader strategy to ensure that Bitcoin is not only present in DeFi but also a cornerstone of its growth. Each new integration reflects steady progress toward building the infrastructure needed for Bitcoin to reach its full potential in decentralized finance.
