New builders and 25+ partners can now begin testing the much-anticipated Bitcoin infrastructure ahead of mainnet, powered by Sui\u2019s high-performance network and Hashi\u2019s novel security mechanism, the Guardian Layer.<\/strong><\/div>\n<\/h5>\n<\/blockquote>\n

Sui, where money moves as freely as messages, today announced that Hashi testnet has officially launched, giving builders, institutions, and infrastructure providers the opportunity to develop and integrate Bitcoin-backed financial applications ahead of mainnet.\u00a0<\/p>\n

Bitcoin has proven itself as the world\u2019s premier digital store of value, amassing over a $1 trillion market cap<\/a> on that use case alone. Its next chapter will be defined by utility. With Hashi testnet now live on Sui, this marks an important milestone in Bitcoin\u2019s necessary evolution, giving developers, custodians, financial institutions, and ecosystem partners their first opportunity to build, integrate, and stress-test Bitcoin-backed financial applications ahead of mainnet.\u00a0<\/p>\n

Alongside today\u2019s launch, Hashi introduces the Guardian Layer, a new defense-in-depth security architecture purpose-built to help institutions securely manage Bitcoin collateral while preserving the transparency and programmability of onchain finance. The Guardian Layer gives Bitcoin the defense it needs to finally go on offense, helping unlock lending, credit, yield strategies, and a new generation of institutional financial products on Sui.<\/p>\n

While institutional adoption has accelerated through spot ETFs, corporate treasury strategies, and expanding regulatory clarity, more than a trillion dollars of Bitcoin remains largely dormant. The infrastructure to safely deploy native BTC into transparent, programmable credit markets has simply not existed. Just as importantly, institutions have lacked confidence that moving native BTC into onchain markets could be done without triggering unnecessary tax consequences. Fenwick, one of the foremost law firms in digital assets, concluded<\/a> that Hashi\u2019s deposit and redemption mechanics should not constitute taxable events under U.S. tax law.<\/p>\n

Hashi testnet is the beginning of the ecosystem buildout that will ultimately power institutional Bitcoin lending, borrowing, and credit origination on Sui. From custody providers and wallet infrastructure to lending protocols and capital markets participants, builders can now begin validating integrations, testing operational workflows, and preparing production-ready applications before Hashi reaches mainnet.<\/p>\n

Developer SDK documentation<\/a>, an integration guide<\/a>, and technical resources<\/a> are available today on sui.io\/hashi<\/a> to help builders begin immediately.<\/p>\n

\u201cEvery major asset class eventually develops deep credit, lending, and liquidity markets,\u201d said Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs, the original contributor to Sui. \u201cBitcoin is no different. Hashi is giving developers the infrastructure to build those markets onchain with the security, transparency, and programmability institutions have been waiting for.\u201d<\/em><\/p>\n

Adding Defense: Hashi\u2019s Guardian Layer\u00a0<\/strong><\/p>\n

A key component of the protocol, unveiled for the first time today, is the Guardian Layer, an additional protection mechanism designed to help secure collateral movement and large transactions. The Guardian Layer introduces configurable safeguards that can slow or prevent potentially malicious activity before collateral leaves the system, helping institutions manage operational risk while maintaining the transparency of onchain markets.\u00a0<\/p>\n

All BTC collateral (or UTXOs) are secured with a 2-of-2 multisig requiring an MPC signature from the Hashi validators as well as a signature from the guardian, creating an additional layer of protection against malicious activity.<\/p>\n

These protections, which are a prerequisite to meaningful institutional participation, complement the broader architecture introduced earlier this year, including automated collateral management, verifiable loan terms, and full onchain visibility into collateral health.<\/p>\n

Expanding the Institutional Ecosystem<\/strong><\/p>\n

As Hashi enters testnet, the ecosystem continues to grow with strategic partners spanning DeFi, banking infrastructure, and capital markets. Wave Digital Assets<\/strong> is deepening its commitment to Hashi after first announcing support during devnet. As an institutional manager, Wave has committed to three years of best efforts to prioritize the tokenization of Bitcoin-yield-bearing bond products on the Sui protocol utilizing Hashi, reinforcing its conviction that programmable Bitcoin fixed-income markets are ready for institutional adoption.<\/p>\n

Hashi\u2019s World-Class Launch Partners\u00a0<\/strong><\/p>\n

These developments fortify an ecosystem that already includes many of crypto\u2019s leading custodians, liquidity providers, wallet providers, DeFi protocols, insurance providers, and infrastructure companies.<\/p>\n

When devnet was announced earlier this year, over 20 day-one launch partners had already committed to building and deploying capital on Hashi, including several of crypto\u2019s heavyweights.<\/p>\n
