Ethereum zkRollup project Loopring sunsets DEX, citing lack of meaningful adoption

Loopring announced that it has shut down its decentralized exchange (DEX) services, with its relayer going offline immediately after the announcement on Sunday.

Though widely recognized as the first zkRollup project on Ethereum, the project said in an X article that it never gained measurable traction.

"As the first zkRollup, we lacked a virtual machine — no composability, no real‑world payment use cases," the team wrote. "That limitation kept our ecosystem from growing."

Loopring also said its zkEVM architecture had been outpaced by modern solutions that are fully compatible with Ethereum smart contracts. The lack of business development and external pressures, including the major exchange delistings of its native token LRC, also contributed to the decision, the team said.

Direct refunds

Loopring noted that it will return users' assets directly and cover all transaction costs, instead of requiring users to generate and submit Merkle proofs. The team said the approach would be the "fairest and most hassle-free" way for users.

In the coming days, Loopring said it will publish a full list of users' final balances on Layer 2, including spot balances and AMM positions. Following a two-week review period of the list, the team plans to then upgrade the Loopring DEX smart contract to only allow team-controlled, whitelisted addresses to transfer assets out of the Layer 2.

The closure of Loopring's DEX comes roughly a year after the project sunsetted its DeFi products, including Dual Investment and Portal, saying it would instead focus on improving the Layer 2 network. Loopring had announced the closure of its wallet service earlier that year. Loopring's CEO, Steve Guo, also stepped down in August 2025.

The price of LRC fell 4.24% in the past 24 hours to trade at $0.012 as of 2:45 a.m. ET on Monday, according to The Block's Loopring price page.

"Loopring was born from a pure cypherpunk vision — we were coders who believed that zero‑knowledge proofs could scale Ethereum," Loopring wrote. "Rather than running a hollow service, we choose to end it gracefully."
