On-chain records indicate the assets were delivered through Flowdesk’s OTC infrastructure.Unlike exchange-based purchases, OTC transactions allow large buyers to acquire assets without placing sizable orders on public order books.That approach can help reduce market impact during execution. It also limits visible buying pressure that often accompanies large spot purchases.The wallet identified in the transaction has been linked to Hayes through previous blockchain activity. The transfer therefore attracted attention across crypto trading communities.According to the data shared by Hupzy, the transaction was valued at approximately $5.42 million based on prevailing Ethereum prices.The purchase follows a period of heightened volatility for ETH, which posted a double-digit gain over the previous 24 hours.Hayes has previously made large directional Ethereum bets, making his wallet activity closely watched by market participants.Ethereum Trading Activity Picks Up as ETH Gains MomentumThe OTC route used for the transaction stood out because it avoided immediate interaction with exchange liquidity.Market participants often use OTC desks when executing large orders that could otherwise create price slippage.Hupzy noted that the Flowdesk transaction structure reduced the likelihood of moving the market during execution.Because the trade occurred away from public order books, no additional spot selling pressure emerged from the transaction itself.Ethereum continued trading above recent consolidation levels following the transfer. Recent market action placed attention on the $2,450 to $2,500 range identified in the shared market commentary.While the transaction represents a notable purchase, the data reflects activity from a single wallet rather than a broader market trend.Lookonchain’s tracking data and Arkham-linked wallet records remain the primary sources confirming the transfer.The development adds another closely watched Ethereum transaction to a market already seeing increased trading activity and renewed attention toward large on-chain movements.The post Arthur Hayes Buys 3,000 ETH Through OTC Deal as On-Chain Data Reveals $5.4M Accumulation appeared first on Blockonomi.
