Sui announced that Cumberland, Fluid, and SwissBorg have joined the Hashi ecosystem, Sui's native bitcoin finance primitive, weeks ahead of its scheduled global testnet launch this July. Sui aims to transition more of Bitcoin's $1.2 trillion market cap into verifiable, productive onchain products. This expanding coalition addresses a critical bottleneck in crypto: solving persistent capital inefficiency by unlocking over a trillion dollars of immobile BTC into DeFi safely.
What Specific Problem Hashi Is Trying to Solve
Previous market cycles demonstrated the systemic dangers of relying on opaque, centralized credit intermediaries such as Celsius, Voyager, and Genesis to generate utility from dormant Bitcoin assets. Hashi replaces centralized balance-sheet trust with verifiable smart contract logic. It maintains a strict separation for safety by design: Bitcoin remains securely on the native Bitcoin blockchain, rather than being wrapped or bridged elsewhere.
What Cumberland Is Actually Bringing to the Coalition
Cumberland, one of the digital asset industry's largest institutional market makers, is joining to evaluate the protocol's structural frameworks and prepare for eventual onchain liquidity provisioning. That evaluation-and-preparation framing suggests Cumberland's involvement is a deliberate, staged entry, not an immediate, full-scale liquidity commitment at this stage.
What SwissBorg and Fluid Are Each Contributing
SwissBorg, a European wealth management app with over one million users, is exploring opportunities to connect its network of European high-net-worth Bitcoin holders and liquidity providers to this ecosystem. That creates new pathways for Bitcoin-backed borrowing and lending. Fluid, a major DeFi lending protocol with a strong record of efficient, safe trades, is now building in preparation for mainnet institutional services. It's positioned to provide institutional-grade lending markets deepening access to Bitcoin-backed credit on Sui.
What Fluid's Co-Founder Said About the Broader Industry Moment
Samyak Jain, Co-Founder & CEO at Fluid, said the next phase of the industry's growth will come from bringing larger pools of capital onchain through infrastructure institutions can trust. He described Hashi's specific approach as getting this right by keeping Bitcoin on its native chain, while verifiable contracts make it productive as collateral. That's different from requiring Bitcoin holders to move their assets off-chain to access DeFi utility.
Why This Coalition Announcement Arrives Ahead of the Testnet Specifically
These new builders join an industry-leading group of infrastructure providers, custodians, and DeFi protocols already engaged with Hashi weeks before its scheduled July global testnet launch. That timing lets institutional participants like Cumberland begin evaluating and preparing their own integration work before the testnet goes live, rather than starting that evaluation process only after launch.
What Bitcoin-Backed Financial Markets at Institutional Scale Would Actually Look Like
The overarching framing behind these expansions positions Hashi as the foundation for Bitcoin-backed financial markets at institutional scale. It addresses the more than $1 trillion of dormant Bitcoin capital that has historically sat unproductive due to the lack of trusted, verifiable infrastructure for putting it to work.
Building institutional coalitions ahead of a major protocol testnet like this reflects the same pre-launch credibility-building approach seen in ETHGas's $3Bn deal with ether.fi. Both secure institutional commitments and validator or liquidity depth before their respective infrastructure products reach full production scale.
Glossary
- Bitcoin finance primitive: A foundational protocol or mechanism enabling Bitcoin to be used productively within DeFi applications while remaining on its native chain.
- Capital inefficiency: A situation where assets sit idle or unproductive rather than being deployed to generate yield or utility.
- Global testnet: A public testing phase of a blockchain protocol, run before full mainnet launch to validate functionality at scale.
