Hashi Testnet Brings Bitcoin Collateral Experiments To Sui
Hashi has launched a testnet on Sui, giving developers a sandbox for a Bitcoin-backed lending design that uses native BTC collateral and a Guardian Layer security model.
The protocol’s GitHub materials describe a system built around multi-layer transaction security, including MPC threshold signatures and a 2-of-2 multisig flow between validators and independent guardians.
That sounds technical, and it is, but the goal is easy to understand: bring Bitcoin into Sui-based DeFi without pretending that cross-chain BTC collateral is simple.
Bitcoin is the largest crypto asset, but using it in DeFi normally requires wrappers, bridges, custodians, or synthetic representations. Hashi is trying to build a more structured way for BTC to support lending on Sui, while keeping additional checks around transaction security.
The main thing to remember is that this is a testnet, not a mainnet product holding real user BTC at scale.
TL;DR
- Hashi has launched a Sui testnet for Bitcoin-backed lending infrastructure.
- The design includes a Guardian Layer, MPC threshold signatures, and 2-of-2 multisig controls.
- The system is not a live mainnet Bitcoin lending product yet.
Bitcoin Collateral Is The Prize Everyone Wants
DeFi has always wanted Bitcoin liquidity.
