7K Aggregator routing issue - Request for engineering review
Hello,
I am requesting help from the Sui ecosystem because I have been unable to reach the 7K Aggregator team.
I have already tried:
-
Email
-
X (Twitter)
-
Discord
and received no response.
Transaction Digest:
B53QvNPhGRAHCUxwVXfR37RCo5ADW1KHcFUZcCChmA5G
Wallet:
0xf6655bc069df048af1c21c0373aebf5336fbd8b3116417015572e78a4c02e35e
This swap was executed through Slush Wallet using the 7K Aggregator.
After analyzing the transaction, I found that the router split my order into four execution paths.
Three routes executed normally.
One route executed as:
250 SUI
→ COIN
→ 107.185556 CETUS
→ only 2.526143 MAGMA
I am not claiming funds were stolen.
I am simply requesting an engineering review to understand why this routing path was selected and whether this execution was expected.
If anyone from the Sui ecosystem or 7K team can help me reach the appropriate engineers, I would greatly appreciate it.
Thank you.
Hi @luchodantini,
The chosen path is based on the specific routing algorithm used by the aggregator. They calculate the best-quoted paths using indexed pool data, but the exact logic is usually proprietary (a black box) for competitive reasons. However, you should always be able to preview the routes and expected output before executing the swap.
Regarding your specific route: are you suspecting that the output amount on that route was calculated incorrectly? Looking at the pool you linked ( Cetus - Empower liquidity. Built for DeFi. ), it is extremely scarce on liquidity. Magma having low liquidity right now is the main reason for the poor execution
Did you happen to notice the quoted amount before confirming the swap? If the quote was drastically different from what actually executed, then that definitely is a serious bug on their end.
I’ve just asked around internally for a 7K team contact btw. I’ll keep you posted here if I find one!
The slippage was properly set to 1%, and there was liquidity in the pool at the time of the swap; clearly, the trade was terrible and I’ve been scammed. The developers at both 7K and Sluch are washing their hands of the matter—NO ONE is taking responsibility—so I am going to make all this information public.
could you confirm if the quoted amount was correct before you signed the transaction? It’s possible you got a bad quote due to low liquidity in the pool on Cetus. But if 7K didn’t check that or calculated the slippage incorrectly based on a wrong quote number, then it’s definitely their mistake
I’ve already asked for their contact, I’ll update you as soon as I hear back
The quoted amount before signing the transaction was correct; I’m not foolish enough to accept $175 less.
