RocketSwap later announced a plan to airdrop tokens to "compensate" users for the theft. They also tried to reassure projects that were migrating away from RocketSwap that there was "no need to run away, your funds are safe".
The attack was a "classic price manipulation" exploit, according to the Ironblocks security firm. The attacker was able to steal 1,152 ETH ($2.13 million) from the protocol. They then tumbled the stolen funds through Tornado Cash.
Lin had created a project called "FrensTech", which aimed to capitalize on the popularity of a product called "friends.tech", and which ultimately accumulated the 14 ETH in fees before he decided to drain liquidity. Lin had not tried to conceal his identity. After the rug pull, Uniswap founder Hayden Adams wrote on Twitter: "Wanted to let people know this person is no longer with the company. Not behavior we support or condone."
Lin was unapologetic, tweeting: "got fired from uniswap, but gained 600 new followers and [crypto Twitter] villain status. net neutral tbh".
SpiritSwap was previously one of the most popular DEXes on Fantom, boasting an all-time-high of $374 million in January. It now has less than $3 million TVL, thanks in part to the Multichain collapse and to the broader cryptocurrency bear market.

The project undertook a vote to shut down the lending service, and use remaining funds in the project treasury to try to compensate those who lost funds in the attack. The project also aims to distribute to victims of the hack claims on any funds that might be returned or otherwise recovered in the future.
The vote passed with 99% of votes in support, effectively sunsetting the project.
