Hashi: Sui-Based Protocol Bringing Native BTC Into Institutional DeFi
Context & launch
Hashi is a new Bitcoin finance protocol being developed on the Sui network with visible institutional anchor support. Core contributors include Mysten Labs, and infrastructure and custody partners such as BitGo, Bullish, FalconX, Ledger and Cubist have indicated participation commitments. The team plans to combine multi-party computation custody with Sui on-chain programs to automate and enforce collateral controls; a devnet is expected ahead of a mainnet release later in the year, with formal audits and verification planned before any live lending activity to meet institutional risk requirements.
How Hashi fits into the institutional yield landscape
Hashi targets native BTC usage rather than wrapped representations, positioning itself against both legacy wrapped-asset markets and newer aggregator products that package third-party yield for custodial clients. Where some institutional offerings aggregate off-chain or multi-provider strategies behind compliance-focused onramps, Hashi attempts to put custody proofs and contract-level enforcement at the core of on-chain lending mechanics so balance-sheet buyers get auditable, enforceable exposure to BTC collateral. That design choice trades some composability for stronger custody guarantees that many institutional allocators now demand.
Market consequences & comparable demand signals
The protocol explicitly courts custodians and trading venues to seed liquidity and aims to capture a portion of the roughly 0.22% of Bitcoin supply currently in DeFi (~$3.07 billion). Independent market initiatives have suggested early institutional allocations into custody-first yield products could move hundreds of millions of dollars in short order — industry participants have cited comparable product rollouts projecting roughly $500 million of near-term flows — indicating there is tangible, if cautious, demand for audited, full-collateral solutions. If Hashi converts even a modest fraction of that demand into on-chain BTC loans, it would increase visible BTC deployed in DeFi and could put downward pressure on margins for centralized lending desks that previously relied on opaque rehypothecation.
Risks and operational constraints
History warns that rehypothecation and opaque collateral practices increase systemic risk, so Hashi’s custody-first architecture responds directly to that failure mode. However, the protocol’s reliance on MPC, formal verification and oracle integrity concentrates new technical dependencies — audits and oracle robustness are gating items for adoption. Broader industry commentary also highlights unresolved concerns about counterparty concentration, potential basis compression as yield sources scale, and the ability of structured products to perform under stress; these factors will shape how quickly institutional capital moves on-chain.

Fireblocks to integrate Stacks, accelerating institutional access to Bitcoin DeFi
Fireblocks will add support for the Stacks layer to give its institutional clients exposure to lending and yield strategies that settle on Bitcoin. The move leverages Stacks’ faster block cadence to address settlement-speed objections that have limited institutional use of BTC-based DeFi, with rollout planned for early 2026.
Lombard unveils Bitcoin Smart Accounts to unlock institutional BTC for onchain finance
Lombard is launching Bitcoin Smart Accounts that issue an onchain receipt token representing custodied BTC so institutions can use it as collateral without transferring custody. The product begins client pilots this quarter with Morpho as the initial liquidity partner and arrives amid a broader custody-first wave of institutional bitcoin yield products seeking to move dormant BTC into defined, auditable strategies.
Ripple Prime integrates Hyperliquid to bring on‑chain derivatives into institutional prime brokerage
Ripple Prime has integrated Hyperliquid so institutional customers can trade on‑chain derivatives through a prime broker while keeping a single contractual counterparty. The move is part of a broader push—alongside recent product and acquisition activity—to fold tokenized liquidity and treasury tooling into institutional workflows, reducing frictions but concentrating new operational and counterparty exposures in intermediaries.
Institutions shift toward TradFi-style bitcoin yield, GlobalStake co-founder says
Institutional allocators are revisiting bitcoin yield as custodial, fully collateralized and market-neutral structures emerge to match familiar TradFi risk profiles. GlobalStake has launched a Bitcoin Yield Gateway and expects roughly $500 million of BTC allocations in the early rollout, a sign that yield-first products may coax treasuries and funds off passive custody.
Citrea launches mainnet and ctUSD to bring DeFi primitives onto Bitcoin
Citrea, a Bitcoin-focused layer‑2 developed by Chainway Labs and backed by Founders Fund and Galaxy, has launched its mainnet and introduced a USD-pegged stablecoin, ctUSD, to enable BTC-native lending and structured finance. The network combines an EVM-compatible zk-rollup model with on‑chain settlement to anchor transaction data to Bitcoin and has assembled partners for lending, product development, and stablecoin issuance.
Hex Trust brings institutional custody to Flare’s FXRP, opening XRP DeFi to funds
Hex Trust has integrated custodial access for FXRP and FLR staking, enabling institutional clients to participate in Flare-based DeFi without exposing native treasury keys. That capability dovetails with Flare’s new lending markets — built on Morpho and surfaced through Mystic-curated vaults (including Clearstar) — which let FXRP act as onchain collateral in discrete, per-market lending pools.
Bitcoin Policy Institute Presses Fed Over Basel BTC Risk Regime
The Bitcoin Policy Institute is mobilizing to alter how the Fed applies Basel rules to Bitcoin, contesting the proposed heavy capital treatment and its commercial effects on bank services for crypto. Expect a public comment campaign centered on BTC , the 1,250% risk metric, and the practical fallout for custody, lending, and market access.
Babylon Labs integrates Ledger signing to unlock BTCVaults for DeFi
Babylon Labs added Ledger hardware signing to its BTCVaults , enabling native Bitcoin to serve as DeFi collateral while preserving user custody. The step accelerates onchain bitcoin utility, reduces reliance on wrapped tokens, and relocates custody risk to end users.
