What Is Loopring?

Loopring is no longer operational. The project shut down its zkRollup, decentralized exchange, and relayer infrastructure in June 2026, following the closure of its smart wallet in 2025. This article is preserved for historical reference. The LRC token still exists as an ERC-20 token and trades on a shrinking number of exchanges.

Loopring (LRC) was an Ethereum Layer 2 scaling protocol that used zero-knowledge rollup (zkRollup) technology to provide high-throughput, low-cost trading and payment capabilities. Founded by Daniel Wang in 2017, Loopring was one of the first protocols to implement zkRollup technology for decentralized exchange functionality. By batching thousands of transactions off-chain and submitting cryptographic proofs to Ethereum, Loopring achieved throughput of over 2,000 trades per second while maintaining the security guarantees of the Ethereum mainnet.

Loopring was originally designed as a blockchain-agnostic protocol, with early plans to support deployment on Ethereum, NEO, and Qtum. Its foundational innovation was ring-matching, a mechanism where orders were not limited to simple two-token trading pairs. Instead, multiple orders could be matched together in a ring, where order A wants to trade Token X for Token Y, order B wants Token Y for Token Z, and order C wants Token Z for Token X. By linking these orders into a ring, all three trades were satisfied simultaneously, improving liquidity compared to traditional pair-based matching.

The protocol used an off-chain order management and on-chain settlement model. Users signed orders from their own wallets and submitted them to a network of relays that aggregated orders into an off-chain order book. Operators matched these orders into rings and submitted settlement transactions to the Loopring smart contracts on Ethereum. Because funds never left the user's wallet until settlement, there was no counterparty risk and no need to deposit tokens into an exchange contract. To address front-running, Loopring implemented a Dual Authoring mechanism that prevented malicious actors from stealing ring-matched trade solutions.

At its peak, the Loopring protocol powered a decentralized exchange supporting both order book and automated market maker (AMM) trading models, and a smart wallet application with social recovery that served as a gateway to its Layer 2 ecosystem. The LRC token was used for protocol fees, staking, and governance: a portion of trading fees was distributed to LRC stakers, another portion was burned, and operators staked LRC as a security bond.

What Happened To Loopring?

Loopring wound down in stages over 2025 and 2026:

  1. June 30, 2025: The Loopring Smart Wallet ceased operations and its app interface went permanently offline, ending the project's consumer wallet product.
  2. July 31, 2025: Loopring's remaining DeFi products, including Dual Investment and Portal, were sunset.
  3. March and April 2026: Major exchanges began delisting LRC. Upbit terminated LRC trading in March 2026, citing transparency and sustainability concerns, and Binance delisted LRC on April 1, 2026.
  4. June 28, 2026: Loopring shut down its DEX and relayer, ending the zkRollup itself. The team posted a final statement that Loopring is no longer operational. Coinbase scheduled a suspension of LRC trading for August 7, 2026.

What About LRC Tokens?

LRC as an ERC-20 Token

LRC continues to exist as a standard ERC-20 token on Ethereum. Holders can store it in any Ethereum wallet, such as MetaMask, and it remains transferable on Layer 1. The Layer 2 balances and features that depended on Loopring's relayer are gone; the project's trustless exit mechanism was designed to let users withdraw Layer 2 funds to Layer 1, but with the relayer offline, users who missed the exit window should consult the project's final announcements for guidance.

Hardware Wallets

Ledger and Trezor continue to support LRC as an ERC-20 token for cold storage, as they do for any standard Ethereum token.

Can You Still Buy Loopring?

LRC still trades, but access is shrinking. Binance delisted LRC in April 2026 and Upbit ended trading in March 2026; Coinbase scheduled a trading suspension for August 7, 2026. Kraken and some other venues continued to list LRC as of mid-2026, and the token remains available on Ethereum Layer 1 DEXs such as Uniswap.

Anyone considering buying LRC should understand that the project behind it is no longer operational. There is no active development, no protocol revenue, and no staking mechanism. The token trades purely on speculation and its market capitalization has fallen accordingly.

Latest Loopring News

In June 2026, Loopring shut down its DEX and relayer, ending its zkRollup after nearly a decade of development. The closure completed a wind-down that began with the smart wallet shutdown on June 30, 2025 and the sunset of its DeFi products the following month. The team's final statement, posted on June 28, 2026, said that "after years of building at the frontier of zero-knowledge technology, Loopring is no longer operational." The shutdown drew attention in the Ethereum community in part because Loopring had pioneered the trustless exit mechanism that zkRollups use to guarantee users can always recover funds, and its closure tested that guarantee in practice. LRC continues to trade at a small fraction of its former value while exchanges progressively delist it.
