Dear users,
JustLend DAO has added WBTC as a collateralizable asset on Nov 28, 2025 (SGT), users will be able to supply and borrow WBTC from that point forward. For more details, please refer to Proposal to add the WBTC Market.
Introduction to WBTC
Following the latest expansion of native WBTC beyond Ethereum and Solana to now include TRON, JustLend DAO intends to list the WBTC market as part of an official collaboration with the WBTC team, integrating the world’s largest crypto asset directly into TRON’s DeFi ecosystem, providing users with new opportunities to lend, borrow, and earn yields using Bitcoin-backed assets.
Since 2019, WBTC has redefined how Bitcoin moves and interacts within decentralized finance. As the unified standard for using Bitcoin across multiple blockchains, it enables BTC to exist natively on chains like Ethereum, TRON, Solana, and many more —allowing it to flow, integrate, and transact without friction. WBTC is not a proxy or derivative; it is Bitcoin re-engineered for composability. A direct, 1:1 representation designed to uphold Bitcoin’s value, while expanding its utility. At its core lies a foundation of transparency and secure custody. Every unit of WBTC is secured through robust standards, including cold storage, multi-signature authentication, and on-chain, publicly verifiable audits.
Market Parameters
The collateral factor of WBTC is set at 75%, and its reserve factor is set at 5%.

| 100% | 300.00% | 285.00% |
As JustLend DAO has granted the right of governance to the community, the decision to launch a new market needs to be decided by the community through voting. We have initiated the proposal on the parameters mentioned above. Please closely follow JustLend Proposals for more details.
