ChainCatcher news, the CKB Eco Fund announced on the X platform that the over-collateralized stablecoin protocol Stable++ has launched on the CKB mainnet, which will achieve the following functions: generating RUSD stablecoin through over-collateralizing BTC and CKB; the first over-collateralized stablecoin on CKB for the Bitcoin and RGB++ ecosystem; future support for CKB Lightning Network and BTC Layer 2 networks.

ChainCatcher news, the CKB Eco Fund announced a strategic partnership with Cross-Chain Tokens (ccTokens) and Meson Finance to facilitate the deployment of ccBTC on the CKB main chain, introducing Bitcoin liquidity to the CKB mainnet. Matrixport subsidiary Cactus Custody will serve as the official custodian of BTC assets, ensuring meticulous management of the Bitcoin reserves backing ccBTC. Leading cross-chain service provider Meson Finance will act as the designated cross-chain bridge for the CKB Eco Fund, officially launching on the CKB mainnet and supporting ccBTC, helping users achieve cross-chain circulation of ccBTC assets on mainstream public chains and BTC Layer 2.ccBTC is a token backed by a 1:1 Bitcoin reserve, which will leverage the features of the Nervos CKB and RGB++ protocols to ensure the secure flow of BTC between the Bitcoin ecosystem, enabling various DApps to utilize Bitcoin assets, such as in DEX, decentralized lending, algorithmic stablecoins, and derivatives markets, as well as in large-scale adoption scenarios like the Lightning Network and Nostr social protocol.

ChainCatcher news, BiFi's new protocol UTXOSwap has released a light paper and plans to launch a public beta in late May. The UTXOSwap team won first place in the CKB ecosystem at the Bitcoin Devcon hackathon and has now reached a strategic cooperation with the CKB Eco Fund.It is reported that UTXOSwap is a decentralized exchange (DEX) protocol based on CKB, aiming to define a new paradigm for Bitcoin Finance transactions. UTXOSwap adopts an intent-based trading model, leveraging the advantages of the UTXO programming model. It currently supports trading of RGB++ and CKB ecosystem assets, with plans to expand in the future to include other BTC ecosystem assets such as Ordinals and Runes.UTXOSwap implements an intent-based hybrid trading model, supporting both automated market maker (AMM) mechanisms and off-chain order book matching. In addition, leveraging CKB's underlying technology, such as cryptographic source language and other chain-level designs, UTXOSwap offers advantages such as nearly 0 Gas for Swap transactions, the ability to pay with any token, support for user-defined AMM curves and fee rates, as well as Dapp native compatibility with multi-chain wallets and seamless operations for L1/L2.

ChainCatcher news, the Stable++ team plans to develop the first over-collateralized stablecoin protocol serving the Bitcoin ecosystem and RGB++ ecosystem based on CKB. The plan is to support new Bitcoin assets such as BTC, CKB, and RGB++ as collateral, generating the first RGB++ stablecoin USDPP through the protocol, and plans to deploy it in the BTC Layer2 issued by UTXO Stack in the future. At that time, USDPP can circulate freely in the Bitcoin ecosystem through the Leap feature of the RGB++ protocol.Team members come from Google, Stanford, UC Berkeley, and CMC top 100 public chains, with rich experience in DeFi protocol design and development, accumulating a TVL of over $50M.The CKB Ecological Fund believes that through strategic investment in the Stable++ protocol, it can introduce a decentralized stablecoin based on native asset over-collateralization to the Bitcoin ecosystem and RGB++ ecosystem, further releasing liquidity in the DeFi ecosystem, and combining technologies such as RGB++ and CKB Lightning Network to unlock new scenarios for payments, lending, and more in the long term.
