Ducat, a Bitcoin Layer 1-native credit protocol, integrated with TRON on September 17, 2026, enabling users to use TRC-20 USDT as a primary settlement asset and access wUNIT, the network's representation of Ducat's Bitcoin-backed dollar token, UNIT. UNIT remains issued against BTC on Bitcoin, while wUNIT allows its value to move through TRON and interact with USDT liquidity. Users can hold wUNIT or swap it for USDT through a dedicated liquidity pool, with providers earning a share of swap fees. Ducat's core system lets Bitcoin holders deposit BTC into non-custodial vaults and borrow UNIT with a 160% minimum collateralization ratio, liquidation beginning below 135%, and a one-time 1% origination fee instead of ongoing interest. The integration separates Bitcoin's role as the source of collateral, Ducat's role in credit and monetary logic, and TRON's role as the settlement environment. Ducat launched on March 18, 2026, as Bitcoin DeFi matured. The announcement came days after a separate Chainflip incident involving 736,442.17 USDT on a TRON settlement route and shortly after Ethena expanded USDe and sUSDe availability to TRON.
