Shell Finance announced the official launch of its decentralized stablecoin protocol, the first layer-one protocol based on the BTC mainnet. Users can obtain stablecoin SUSD by pledging BTC ecosystem assets such as Ordinals NFT and BRC-20. This move not only improves the liquidity of BTC layer-one assets, but also lays the foundation for the development of BTCFi. In the future, Shell Finance plans to expand to other UTXO model networks to further expand the application scenarios of SUSD, and the market prospects are optimistic.
