Two nights ago, my #CCTP cross-chain call caused a mistake I still deeply regret. Everyone knows #Circle has now opened native cross-chain services for $USDC on six chains. However, they only provide contracts for invocation and API endpoints for mint confirmation. Therefore, ordinary users cannot mint through an official web frontend. Having used CCTP multiple times before, I didn't perform thorough checks this time and successfully completed the contract call. Unbeknownst to me, this was just the start of a nightmare. Circle, whom I deeply trusted, simply said they couldn't handle the issue, without giving a convincing reason.
1. Incorrect Contract Call
According to the official documentation [https://t.co/VCy8PtOn5R], a typical cross-chain initialization transaction should include the following four variables: The 'mintRecipient' is the recipient's address on the target chain, using a 64-bit Bytes32 format. However, during the call, I did not perform the StringtoBytes32 format conversion.
Since every ETH address is 40 characters long, the shortfall of 24 zeros was added to the end, not the beginning. This resulted in the USDC being transferred to an empty address with 24 extra zeros at the end. [https://t.co/wcfN1qmHbH]
2. Confirmation Transaction Due to the issue in step 1, the target recipient address changed, and ultimately 100,000 USDC were transferred to this address on ARB: 0x8e662632c1c8eee5000000000000000000000000. [https://t.co/2l8cvKIJxI]
3. Attempting to Recover Upon discovering the problem, I immediately tried to contact PeckShield and SlowMist to help reach out to Circle, but the next day the consistent response was that I needed to contact Circle myself. Meanwhile, I sought help in Circle's CCTP developer channel and tried to submit a support ticket on Circle's official website. However, possibly due to the Christmas season, they did not respond immediately, and I still haven't received any auto-reply acknowledging my support case. The Discord community and a friend suggested I directly request help via Circle's customer support email.
I'm very grateful for the community Mod vcarl's help. I understand the delay in Circle's support due to the holiday season. However, it's puzzling that I couldn't find any email or online communication channel for help on Circle's entire official website. The only option was a ticket submission page, which like a black hole, never responds, and even limits the text length to less than a typical tweet.
4. Shattered Hope
With the help of friends and community staff, I started contacting the help email they provided. Unlike the official website's ticket submission page, Circle viewed and replied to my email within minutes, asking for specific event information, which I immediately provided.
I must admit Circle's support email was very efficient. After receiving my detailed information, they wrote their first effective reply: 'Unfortunately, USDC transactions are irreversible by design and cannot be canceled or recalled once they have been initiated. Since this transaction was initiated and processed successfully to an address that does not exist, it is not possible to cancel or recall it at this time.' Circle's eloquent response subtly informed me they couldn't retrieve the funds because it was just a simple USDC transfer to the wrong address.
I initially thought Circle's internal team might not be well-trained or informed about the CCTP protocol, so I replied again with all the technical details of the event. The second effective reply I received today was identical: 'Unfortunately, USDC transactions are irreversible by design and cannot be canceled or recalled once they have been initiated. Since this transaction was initiated and processed successfully to an address that does not exist, it is not possible to cancel or recall it at this time. For your reference, please refer to our User Agreement: [https://t.co/525KAf7mmU]' The same reply text, telling me they couldn't help retrieve the assets. Two years ago, in the USDC 2.1 version update, Circle stated they could help users retrieve USDC funds mistakenly transferred to a contract: [https://t.co/YAjcjjox8o] This contradiction is confusing and hard to understand. Indeed, it was my mistake that led to the USDC being transferred to the wrong address. However, I believe I have clearly proven the actual target of the transfer, and the Ethereum address with 24 extra zeros at the end cannot be used by anyone. It's puzzling and disrespectful how Circle's official response was dismissive and showed a lack of respect for their users.
Therefore, I request everyone's help in spreading the word and seeking viable solutions for fund recovery. To whoever provides decisive help in recovering the funds, I will give 40% of the recovered funds as a reward, and 10% will go to the friends who offered help or for charitable purposes.
Thank you for reading this far, and I hope everyone checks contracts carefully before invocation to avoid similar situations.
I survived the bear market and claimed my $FRAME tokens!
