@TheDanDraper1 The key question is, "Was it settled onchain or offchain?". If settled offchain, was it collateralized through conditional value transfer through wallets with private keys?
The fact that it was non-deliverable likely means offchain, but collateralization needs to be done onchain
@关键的问题是，“它是在链上解决还是在链外解决？”。如果在链外结算，是否通过带私钥的钱包进行有条件的价值转移进行抵押？
不可交付的事实可能意味着链外交易，但抵押需要在链上完成
