Let’s assume that I’ve small crypto alternate website known as “MyExchangeWebsite”.
It really works like this: consumer creates ETH-BTC order, specifies his BTC handle and sends ETH to my ETH handle, I alternate it on Bitfinex and ship ensuing BTC to the desired consumer’s handle. Website may be very easy and does not have accounts (non-custodial mannequin).
By some purpose consumer made a one-character typo in his BTC handle for ETH-BTC order and it is inconceivable now to withdraw BTC, as checksum is bad. Consumer observed that he did not obtain BTC and contacts me to offer proper handle.
- Am I proper in my understanding that it is secure to alter consumer’s handle and it is inconceivable to rip-off MyExchangeWebsite by third one that is aware of about typo and consumer’s order particulars?
- If it is not one-character, however N-characters typo. At what N it turns into unsafe to alter N characters in consumer’s handle?
- What’s the easiest way to ensure that I am involved with the true order creator?
- If consumer sends BTC to an handle for which he does’t personal personal keys, its not non-custodial.
- Many of the web sites that do such crypto-crypto alternate ask for a refund handle upfront and different points are solved relying on the case.
- Greatest solution to confirm issues with out KYC is by asking the consumer to signal a message for a number of bitcoin addresses that he used earlier. Instance: Somebody despatched me 1 BTC and I must confirm in an e-mail communication that he’s the identical particular person, I can ask him to signal a message utilizing bitcoin handle that was used as enter within the transaction.
