Ethereum user paid commission $430 000 for an unsuccessful attempt to buy STRP tokens – Bits Media

Ethereum user, attempted to participate in the Strips token sale on the MISO platform decentralized exchange SushiSwap, Paid the commission $430 000 for an unsuccessful transaction.

According to The Block, given the great competition, STRP tokens on the MISO platform were sold out in just a few seconds. Therefore, during the sale, the participant tried to use the Flashbots protocol, to get priority. The protocol allows you to send a transaction directly to the miner for its prompt inclusion in the block. It is assumed, that Flashbots transactions remain confidential, until they are included in the block.

Однако в этом случае что-то пошло не так, и транзакция попала в публичный мемпул. Она была обработана майнером Эфириума и включена в блок. Но поскольку токены STRP были распроданы слишком быстро, then the transaction ended unsuccessfully, and the potential buyer was left without tokens. Nonetheless, he still paid the transaction fee, which amounted to 123 ETH (about $430 000).

"This transaction was sent to the mempool, what can be seen from Etherscan. She did not appear in the Flashbots relay", – Flashbots product development manager Robert Miller wrote on Twitter (Robert Miller).

The user then made a second transaction to purchase the same tokens, again deciding to use Flashbots. but, considering the “fabulous” cost of the first transaction, this deal was canceled. To inform the network that a transaction has been cancelled., I had to send another one for the amount 30 ETH ($105 000).

A few weeks ago, a similar situation occurred with a user of the DeversiFi service - he paid a commission of $23.7 million per transaction in stablecoins USDT in the amount $100 000. Fortunately, Miner, processed the transaction, returned it to him $22.1 million.
