Case summary
What happened
bitbank currently operates its crypto-asset lending service. First-party support states that the standard maturity is one year after contract formation and that the lent crypto plus the prescribed usage/lending fee is returned within the published return window after maturity. First-party support also documents early termination through support subject to an early-termination fee. In its Ethereum PoW fork guidance, bitbank explicitly distinguished ETH lent through the service from the segregated-management balance used for ordinary exchange custody in that context. CYA therefore records lending counterparty exposure and does not generalize ordinary exchange-custody protections to lent balances. Annual transaction-report guidance establishes operation by historical reporting periods but does not establish an exact original launch date, so no launch date is inferred.

Current first-party support documents one-year maturity and early-termination mechanics. Published rates remain issuer terms, not verified realized returns. Current return mechanics are not evidence of universal historical repayment performance.

The reviewed materials describe customers lending crypto assets to bitbank under a lending contract in exchange for contractual usage/lending fees. First-party ETHW fork guidance distinguishes lent ETH from the segregated-management balance used for ordinary exchange custody in the documented fork context. CYA therefore represents borrower/counterparty economic exposure during the lending contract and does not infer segregated custody, insurance or guaranteed principal for lent balances. Exact historical legal terms may vary across periods.
Known unknowns
Uncertainty
Exact original launch date is not established by the reviewed first-party evidence. Published lending-fee rates are issuer product terms, not independently verified realized returns. Current return mechanics do not establish universal historical repayment performance.
