On October 18, the Stable++ protocol was officially launched on the CKB mainnet. As the first over-collateralized stablecoin protocol developed on CKB, Stable++ serves both the Bitcoin and RGB++ ecos. The protocol supports BTC and CKB as collateral to mint the first RGB++ stablecoin, RUSD.

Looking ahead, Stable++ plans to support the CKB Lightning Network-Fiber network and be deployed on the BTC Layer2 issued by UTXO Stack. With the Leap feature of the RGB++ protocol, RUSD will soon be able to circulate freely within the Bitcoin eco.

Stable++ protocol, strategically invested by the CKB Eco Fund, aims to introduce a native asset-based, over-collateralized decentralized stablecoin to the Bitcoin and RGB++ ecos, further unlocking liquidity of the DeFi eco. By leveraging technologies such as RGB++ and the CKB Lightning Network, Stable++ provides support for payments, lending, trading, and other scenarios within the eco.

About Stable++:

Stable++ is an over-collateralized stablecoin protocol built on the RGB++ Layer, aiming to provide a reliable and stable store of value within the Bitcoin eco.

About CKB:

CKB is the first fully BTC-isomorphic L2 (PoW+UTXO), offering a more decentralized, secure, and Bitcoin-compatible L2 solution.

CKB scales Bitcoin’s programmability and interoperability with RGB++ protocol, which maps Bitcoin UTXOs to CKB Cells, enabling the seamless transfer of Bitcoin L1 UTXO-based assets such as Ordinals, Atomicals, and Taproot, to CKB without any cross-chain bridge and vice versa. UTXO Stack, a Bitcoin L2 “OP Stack” secured by CKB and powered by RGB++, enables high-performance parallel chains, offering near-unlimited scalability without compromising security. CKB Lightning Network will connect with Bitcoin’s Lightning Network, facilitating a bi-directional, censorship-resistant, permissionless and trustless flow of assets between the two networks.

CKB mainnet launched in Nov. 2019 and completed its first mining reward halving in Nov. 2023.
