According to Techub News, 21Shares' parent company, cryptocurrency investment product company 21.co, tweeted that it has launched a Bitcoin asset "21BTC" based on Solana.
21BTC is Solana's native token, providing users with convenient native BTC access on Solana similar to Circle's USDC integrating multiple chains - no cross-chain bridge is required, and there is no locking and minting technology. 21BTC is 100% physically collateralized, and the underlying BTC is stored in a cold wallet by a third-party custodian using a multi-signature agreement. Minting and destruction are achieved through 21.co's Onyx asset management operation protocol.
