- BIMA and exSat join forces to drive Bitcoin adoption in DeFi with a $100M Bitcoin-backed stablecoin initiative.
- USBD stablecoin offers Bitcoin holders capital efficiency and yield opportunities without needing to sell BTC.
- By partnering with BIMA, exSat allows users to join DeFi using only Bitcoin transactions.
BIMA, a project focused on Bitcoin-backed stablecoins in decentralized finance, has entered a strategic partnership with exSat, a Bitcoin bank and layer-2 system. At the Bitcoin conference in Las Vegas on May 28, 2025, it was announced that the collaboration wants to increase Bitcoin’s role in DeFi, starting with $100 million deployed in Bitcoin.
However, the goal is to quickly expand their partnership, moving from 1,000 BTC to more than 5,000 BTC, which would add up to around $500 million. With this growth, Bitcoin will experience stronger involvement in DeFi, making it an important step for its role in decentralized finance. While, the key to BIMA’s innovative system is the stablecoin USBD, which is linked to Bitcoin, supports efficient use of capital and allows users to share in Bitcoin’s growth.
BIMA and exSat Partnership
While, with the launch of BIMA’s mainnet, the platform also released USBD, which is an overcollateralized stablecoin using Bitcoin derivatives to improve capital efficiency. Bitcoin owners using USBD can collect interest without the need to sell their cryptocurrency. A stabilized crypto asset lets decentralized and centralized finance users gain access to increased stability, Bitcoin exposure and additional yields on the blockchain.
Sid Sridhar, CEO of BIMA, pointed out how important the collaboration is. Sridhar stated that the exSat partnership marks an important move toward making Bitcoin a valuable asset for DeFi. ExSat is preparing the financial structure for a programmable Bitcoin economy, and BIMA will play a key part by allowing efficient and secure USBD drives to be use in both DeFi and CeFi areas.
Under the agreement, BIMA will handle exSat’s official stablecoin services and use esBTC and iBTC tokens in their structured financial assets. Because of this partnership, people using Bitcoin can now access fresh financial services without having to move their funds.
Building Bitcoin Banking System
Yves La Rose of exSat discussed the benefits the partnership could bring. La Rose pointed out that ExSat plans to create a fully independent Bitcoin banking system. Together with BIMA, we allow users to borrow USD by depositing Bitcoin, giving them the opportunity to try a range of yield strategies that require no permission. This makes Bitcoin easier to use and helps users maintain their place in the Bitcoin network.
However, BIMA and exSat are leading the way as Bitcoin moves further into the world of decentralized finance. While, working together, they strive to provide Bitcoin holders with financial services as the world moves toward decentralization.
