Hi Team,

The following Ethereum transaction hash contains an ‘atomicMatch\_’ event from the Project Wyvern Exchange (OpenSea) which is shown on Etherscan. Running this transaction hash in the following query only shows the ‘OrdersMatched’ event which is the event that is emitted from the ‘atomicMatch\_’ event. I have queried many of these OpenSea transactions and this is the first one that does not contain the underlying ‘atomicMatch\_’ event. Can you please investigate and get back to me.

TXHASH:  
0x4499dc75facb4cd27894196aac00bcb0ffbe3d64de87105878451d5637662f90

QUERY:  
{  
ethereum(network: ethereum) {  
smartContractEvents(  
txHash: {in: [“0x4499dc75facb4cd27894196aac00bcb0ffbe3d64de87105878451d5637662f90”]}  
smartContractAddress: {is: “0x7be8076f4ea4a4ad08075c2508e481d6c946d12b”}  
) {  
arguments {

value  
}  
smartContractEvent {

}

block {

unixtime  
}

}  
transaction {

}  
}  
}  
}

Thanks,

can you show me where I can see this? Because I can’t see this event at transaction 0x4499dc75facb4cd27894196aac00bcb0ffbe3d64de87105878451d5637662f90
