21.co offers Wrapped Tokens that provide onchain access to cross-chain liquidity, connecting the security of traditional finance with the decentralized world. Their products, such as 21BTC, are 100% physically collateralized, with the underlying assets held in cold storage by institutional-grade custodians. The minting and burning processes are centralized and managed by Onyx, 21.co’s proprietary operating system, to enhance cross-chain security. These wrapped tokens introduce liquidity for popular alt-L1 protocol tokens to the Ethereum ecosystem, serving onchain index protocols, yield protocols, and users who wish to consolidate their crypto portfolio into a single ERC-20 wallet. The company emphasizes security through audits by firms like Halborn and the use of Chainlink's Proof of Reserve.
