Bitcoin staking platform Solv Protocol introduced a classification system for the underlying assets of SolvBTC reserves, dividing them into core reserves (native BTC, Binance-backed BTCB) and innovative reserves (encapsulated assets such as WBTC, cbBTC). "This setup enhances stability and risk management through minting caps and cross-chain interest rate limits on innovation reserves," the team said. "Solv is now one of the major multi-chain BTC liquidity staking token issuers with over 24,000 BTC ($2 billion) in reserves across more than 10 networks, including the Ethereum and BNB chains."
