Bubblemaps spotted a wallet buying JESSE in a second, while Arkham confirmed two snipers made huge profits on the same block.
On-chain intelligence layer Bubblemaps reported that a wallet linked to early trading activity around Base founder Jesse Pollak’s new creation coin executed a buy within the “first second” of the token’s release.
The wallet identified as 0xB102 spent approximately $250,000 purchasing JESSE tokens at the precise time the contract went live, before Pollak publicly shared the contract address.

According to the latest findings from Bubblemaps, the tokens were then moved to another address, 0x9572, which sold most of the holdings for almost $800,000. This generated an estimated profit of around $600,000. Bubblemaps attributed the accuracy of the exchange to the wallet’s ability to detect the launch of the token at the moment of its creation and act instantly, while describing it as a very effective snipe executed immediately after the coin becomes available.
Arkham Intelligence separately identified similar early purchasing behavior during the same launch. The company reported that two sniper wallets collectively generated over $1.3 million in profits when Pollak’s token was deployed on Base. As part of the launch, 500 million JESSE tokens, half of the total supply, were added to a liquidity pool.
Within this same on-chain block, traders using automated tools purchased 261.7 million tokens. Arkham found that the two most profitable wallets yielded approximately $707,700 and $619,600, respectively. One of these traders acquired approximately 7.6% of the token supply by spending approximately $191,000 and paying over $44,000 in priority fees to the base sequencer to ensure early inclusion.
Arkham tied the ability to make these purchases of the same block to the introduction of flashblocks on Base, a feature that divides each block into a series of 200 millisecond micro-blocks. Although the Ethereum Layer 2 network incubated by Coinbase maintains block times of two seconds, flashblocks allow bots to detect a token deployment transaction as soon as it appears in a first microblock and immediately submit a costly buy order that settles into the next one.
This sequence causes deployment and purchase to be processed in the same complete block, enabling highly competitive sniping without access to private memory information.

A July analysis from Galaxy Digital showed that Base had become the most profitable Layer 2 network at the time, having generated an average of $185,291 in daily revenue over the previous six months.
The report credits Base’s EIP-1559 priority fee model and strong DEX activity for leading other rollups. He also noted that the introduction of Flashblocks helped distribute priority fees more evenly across block locations while maintaining overall revenue strength.
