BTC Trillion-Dollar Market Cap Dormant, "Awakener" Hashi Testnet Goes Live on Sui

Even though the crypto market remains in a deep bear market, Bitcoin's market cap has consistently stayed above the trillion-dollar level, establishing itself as the world's largest digital store of value asset. However, an awkward fact remains: of this trillion dollars in capital, the portion that is actually "utilized" is minuscule — according to DefiLlama, the BTC currently in DeFi is worth only $4.3 billion, less than 0.33% of the total market cap.

In other words, over 99.6% of BTC sits quietly in wallets, generating no yield, participating in no lending, and serving as collateral for no financial product — they are merely "held," not "used."

If we place BTC's $1.31 trillion market cap into the coordinate system of China's capital market, its scale roughly equals the combined market value of the six largest state-owned banks, or five Kweichow Moutais. This is not a scale that can be ignored.

Bitcoin's next chapter will no longer be written solely by "store of value" but will also be defined by "utility."

In July, the Hashi testnet officially launched on Sui. This means developers, custodians, financial institutions, and ecosystem partners now have a practical environment to build integrations and stress-test Bitcoin-collateralized financial applications — to run through the complete product cycle ahead of the Hashi mainnet launch.

Guardian Layer: The Deep Defense Line for BTC Collateral

Debuting alongside the testnet is Hashi's security architecture — the Guardian Layer.

According to the official introduction, the Guardian Layer is a defense-in-depth security architecture designed specifically for institutional-grade BTC collateral management. On top of Hashi's existing threshold signature mechanism (requiring one-third of Sui validators to approve before funds can be moved), it adds an independent security check — a second independent verification layer. All BTC collateral is under 2/2 multi-signature: both the MPC signature from Hashi's verification nodes and the Guardian's signature are required to release BTC, providing an ultimate insurance layer against potential validator malfeasance or systemic risks.

Odaily Note: Defense-in-depth is a classic security engineering concept. Its core idea is to overlay multiple layers of independent security mechanisms so that even if one layer fails, the remaining layers can still provide protection — rather than placing all security bets on a single link.

For institutions, this means: collateral monitoring no longer relies on a single link, every movement of capital undergoes multi-layered independent verification, and the security of funds in lending and credit markets receives structural safeguards.

Wave Digital Assets: A Three-Year Commitment Anchoring the BTC Fixed Income Market

Among Hashi testnet's first-day partners, the addition of Wave Digital Assets LLC (hereinafter Wave) is particularly noteworthy.

As an SEC-registered investment advisory firm, Wave not only participated in Hashi's early development but also made a clear long-term commitment: to use its best efforts to prioritize tokenizing Bitcoin yield-bearing bond products on the Sui protocol via Hashi within three years — a definitive bet on the judgment that "the programmable Bitcoin fixed income market is ready for institutional adoption."

Wave CEO David Siemer previously stated: "Hashi is the missing credit layer, now finally completed, providing stable native yields to institutions."

25+ Partners: Full-Chain Coverage from Custody to Auditing

With the launch of the Hashi testnet, the ecosystem has assembled over 25 partners, covering the entire chain of Bitcoin finance:

Custody and Wallet Access: BitGo (institutional custody client), Blockdaemon, Cobo, Fordefi under Paxos (institutional wallet and infrastructure provider), Cubist (cross-chain collateral infrastructure), Ledger (self-custody service provider), SwissBorg (European high-net-worth retail/institutional asset management wallet);

Lending, Trading, and Liquidity Provision: Bullish (institutional crypto asset platform), Cumberland (institutional-grade crypto market maker and liquidity provider), Erebor (OCC-chartered bank), FalconX (institutional-grade prime brokerage);

DeFi and Lending Applications: AlphaLend, Bluefin, Current, Scallop, Suilend (Sui-native DeFi protocol supporting retail lending on day one), Fluid (high capital efficiency system connecting lending, liquidity, and other financial products), Navi (one of the largest and longest-running DeFi protocols on Sui);

Treasury and Asset Management: Concrete by Blueprint Finance (yield infrastructure platform), Inveniam Capital (RWA yield strategies), Wave Digital Assets LLC;

Indices, Oracles, Insurance, and Security Auditing: CF Benchmarks (crypto index provider for oracles), Soter Insure (institutional-grade crypto-native insurance denominated in BTC), Asymptotic, Certora, OtterSec (smart contract security and formal verification auditing)...

Odaily Note: Formal verification is a technique that uses mathematical methods to prove that code behavior conforms to design specifications, providing stronger correctness guarantees than traditional code audits — this is particularly crucial in institutional-grade financial products.

When the devnet was announced earlier this year, over 20 first-day partners had already committed to building and deploying capital on Hashi. Now with the testnet launch, the partner lineup has further expanded, and the coverage has extended from infrastructure to broader financial service segments.

"Bitcoin Is No Exception"

"All major assets have ultimately developed highly credit-based lending and liquidity markets, and Bitcoin will be no exception," said Adeniyi Abiodun, Co-Founder and Chief Product Officer of Mysten Labs. He added, "Hashi is providing developers and infrastructure service providers with the opportunity they've been waiting for — a secure, transparent, and on-chain programmable opportunity."

The weight of this statement lies not in repeating something "correct" — historically, every major asset class like gold, real estate, and sovereign bonds has indeed followed the path from "passive holding" to "active credit." Instead, it delivers a concrete answer: BTC's trillion-dollar market cap has the potential to form credit and liquidity markets of equally profound depth on-chain.

What Can Developers Do?

With the Hashi testnet launch, developer SDK documentation, integration guides, and technical resources have been published at sui.io/hashi.

On the tax issues that BTC holders are very concerned about, a legal analysis by Fenwick previously pointed out that locking BTC via Hashi and receiving the receipt token hBTC should not constitute a taxable event under U.S. federal income tax law — because hBTC is merely a certificate of ownership for the underlying BTC, not a separate asset.

Odaily Note: Fenwick's core analogy is "checking a coat and receiving a coat check ticket" — neither receiving the ticket nor retrieving the coat constitutes a taxable event because ownership never transfers.

From devnet to testnet, from concept validation to practical rehearsal, Hashi is step by step turning the "utility" narrative for trillions of dollars of BTC into a verifiable, programmable, and auditable on-chain financial infrastructure. Perhaps this is precisely the starting point for Bitcoin's next chapter.
