PANews reported on May 20 that Danny, the founder of Deezy, stated on the X platform that he discovered Magic Eden was employing a "trick" on Coinbase. Magic Eden adds small outputs for market fees in each market purchase, with amounts ranging from 1,000 to 2,000 satoshis. Integrating these small transactions in the future will be troublesome and incur additional costs. Cleverly, Magic Eden did not use its own address to receive these UTXOs (unspent transaction outputs) but chose a Coinbase account address, causing these small deposits to go directly into Magic Eden's Coinbase account. Coinbase is responsible for the integration fees. However, due to its large scale and slow response, Coinbase was unaware of this and suffered significant losses during the integration process.

Additionally, Mempool founder Mononaut stated that in the past 24 blocks, Coinbase Prime integrated 92,400 small transaction inputs from Magic Eden's address, distributed across 308 transactions, at a price of approximately 7 sats/vb. These transactions paid a total fee of about 0.59 BTC to recover approximately 1.75 BTC.
