ShentuShield addresses one of the most significant issues in the blockchain ecosystem: the inability to recover lost or stolen cryptocurrencies. On a technical level, ShentuShield can be described as a decentralized reimbursement protocol, which acts as a DeFi insurance mechanism. By participating in the ShentuShield program as a Shield Purchaser and paying a small CTK fee, you effectively insure your cryptocurrency. If you decide to join ShentuShield as a Collateral Provider, you can earn passive income in CTK tokens in exchange for allocating some funds that will be used as reimbursement collateral.
