No wind-down period was provided. The closure affected the decentralized exchange, its automated market maker, and all relayer operations. The shutdown date was June 28, 2026. The Loopring team stated that the protocol 'never gained meaningful adoption' and described themselves as 'engineers, not business operators,' acknowledging they lacked the commercial capabilities required to compete in a maturing market. This represented the final step in a multi-year contraction: Loopring Wallet ceased mobile operations on June 30, 2025, and DeFi products such as Dual Investment and Portal had been retired prior to the DEX closure.","heading":"Shutdown Overview","severity":"high","sources":[{"credibility":2,"name":"Loopring Shuts Down Its DEX Disabling the Trustless Exit It Pioneered — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/06/29/loopring-shuts-down-its-dex-disabling-the-trustless-exit-it-pioneered/"},{"credibility":2,"name":"Ethereum zkRollup project Loopring sunsets DEX, citing lack of meaningful adoption — The Block","type":"news_article","url":"https://www.theblock.co/post/406492/loopring-sunsets-dex"},{"credibility":2,"name":"Loopring shuts down Ethereum's first zk rollup DEX after years of decline — crypto.news","type":"news_article","url":"https://crypto.news/loopring-shuts-down-ethereums-first-zk-rollup-dex-after-years-of-decline/"},{"credibility":2,"name":"Loopring Shuts Down Its Pioneering Ethereum zkRollup DEX — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/06/29/loopring-shuts-down-its-pioneering-ethereum-zkrollup-dex/"}]},{"content":"The Loopring team publicly attributed the shutdown to three primary factors. First, weak user adoption: the protocol never found lasting demand due to its lack of composability with the broader Ethereum smart contract ecosystem, as its early architecture lacked a virtual machine, preventing the integration of DeFi primitives and payment applications that later networks offered. Second, technical obsolescence: modern zkEVM networks such as zkSync Era, Scroll, and StarkNet run Ethereum-compatible smart contracts natively, rendering Loopring's specialized non-EVM architecture outdated. Third, sustained business pressure: the team acknowledged limited business development capacity and cited a series of major LRC token delistings across exchanges in early 2026 as an accelerating factor. The team stated that the technology it helped pioneer 'has been outpaced' by successor networks and that they preferred a deliberate wind-down 'rather than running a hollow service.' TVL declined approximately 99% from a peak near $760 million in November 2021 to roughly $8 million at the time of closure, and LRC fell from an all-time high of approximately $3.75 to around $0.01.","heading":"Reasons for Closure","severity":"medium","sources":[{"credibility":2,"name":"Loopring Shuts Down Its DEX Disabling the Trustless Exit It Pioneered — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/06/29/loopring-shuts-down-its-dex-disabling-the-trustless-exit-it-pioneered/"},{"credibility":2,"name":"Loopring Shuts Down Its Pioneering Ethereum zkRollup DEX — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/06/29/loopring-shuts-down-its-pioneering-ethereum-zkrollup-dex/"},{"credibility":2,"name":"Loopring shuts down DEX — What went wrong for Ethereum's L2 pioneer? — AMBCrypto","type":"news_article","url":"https://ambcrypto.com/loopring-shuts-down-dex-what-went-wrong-for-ethereums-l2-pioneer/"}]},{"content":"The most contested aspect of the shutdown is the method by which user funds are being returned. A defining security property of zkRollup designs is that users can withdraw funds directly from the Ethereum Layer-1 smart contract via a Merkle proof, without requiring the operator's cooperation. This 'trustless exit' mechanism is intended to protect users even if the protocol team disappears or acts maliciously. Loopring is disabling this mechanism as part of the wind-down. The team announced it will upgrade the DEX smart contract to a version that 'only allows whitelisted addresses (controlled by us) to transfer assets out of the L2 system,' replacing the self-custody exit with a centralized batch distribution. Under the announced process: (1) The team will publish a final list of Layer-2 balances. (2) AMM liquidity positions will be converted to their underlying tokens. (3) A two-week window will be opened for users to flag discrepancies. (4) Funds will then be sent in batches to users' associated Ethereum Layer-1 addresses. (5) The team stated it will cover all gas costs. (6) Accounts with balances below $10 will be excluded from distribution entirely, with the team citing process efficiency as justification. The team acknowledged the approach is 'more centralized than the original self-custody exit mechanism' and framed the trade-off as sparing users 'the technical difficulty of generating proofs.' DeFi researchers and commentators noted that this decision inverts the protocol's core value proposition at the moment it matters most.","heading":"User Fund Distribution and Trustless Exit Controversy","severity":"high","sources":[{"credibility":2,"name":"Loopring Shuts Down Its DEX Disabling the Trustless Exit It Pioneered — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/06/29/loopring-shuts-down-its-dex-disabling-the-trustless-exit-it-pioneered/"},{"credibility":2,"name":"Ethereum zkRollup project Loopring sunsets DEX — The Block","type":"news_article","url":"https://www.theblock.co/post/406492/loopring-sunsets-dex"},{"credibility":2,"name":"Loopring Shuts Down Its Pioneering Ethereum zkRollup DEX — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/06/29/loopring-shuts-down-its-pioneering-ethereum-zkrollup-dex/"}]},{"content":"In June 2024, Loopring's smart wallet users suffered a security breach resulting in the theft of approximately 1,373 ETH, valued at approximately $5 million at the time. The attack exploited a vulnerability in Loopring's Two-Factor Authentication (2FA) Guardian service. The attacker compromised Loopring's official Guardian service and used it to impersonate wallet owners, obtaining approval for unauthorized wallet recoveries. The attack specifically targeted wallets that used only the Loopring Official Guardian as their sole Guardian, without additional independent co-signers. Approximately 58 user addresses lost funds as a result. Loopring engaged blockchain security firm SlowMist to investigate how its 2FA service was compromised and temporarily suspended Guardian-related operations. The team stated it was 'willing to collaborate with more law enforcement and security teams to help users recover lost assets' while noting that 'users are ultimately responsible for the security of their self-custody.' The June 2024 breach is widely cited as a material factor in accelerating the protocol's decline in user trust and adoption. A separate attack on the Loopring relayer in April 2024 reportedly caused an internal loss of team assets, though detailed public documentation of this incident is limited.","heading":"June 2024 Security Breach — Guardian 2FA Compromise","severity":"critical","sources":[{"credibility":2,"name":"LRC falls to 4-month low as Loopring's 'most secured wallets' hit with $5 million breach — CryptoSlate","type":"news_article","url":"https://cryptoslate.com/lrc-falls-to-4-month-low-as-looprings-most-secured-wallets-hit-with-5-million-breach/"},{"credibility":2,"name":"Loopring suffers $5 million hack after Guardian 2FA service is compromised — The Block","type":"news_article","url":"https://www.theblock.co/post/299177/loopring-suffers-5-million-hack-after-guardian-two-factor-authentication-service-is-compromised"},{"credibility":2,"name":"Explained: The Loopring Hack (June 2024) — Halborn Security","type":"research","url":"https://www.halborn.com/blog/post/explained-the-loopring-hack-june-2024"},{"credibility":2,"name":"Loopring releases June hack incident report: 58 users affected — ChainCatcher","type":"news_article","url":"https://www.chaincatcher.com/en/article/2146841"},{"credibility":2,"name":"Loopring Hack: 2FA Breach Instigates $5 Million Drain — blocmates","type":"news_article","url":"https://www.blocmates.com/news-posts/loopring-hack-2fa-breach-instigates-5-million-drain"}]},{"content":"The LRC token experienced a cascade of major exchange delistings in early 2026 that the team cited as a contributing factor to the decision to shut down. In January 2026, South Korean exchanges Upbit, Bithumb, and Korbit placed LRC on a delisting watchlist, flagging it as a 'caution' asset and allowing a period for the project to address compliance concerns. On March 16, 2026, Upbit and Bithumb proceeded with full delistings of LRC trading pairs, with user withdrawals permitted until April 16, 2026. Upbit cited three specific concerns: lack of transparency in project operations, doubts about long-term sustainability, and questions about the project's legitimacy. The delistings caused LRC to fall approximately 10% on the announcement. Binance subsequently announced on March 18, 2026 that it would delist LRC alongside seven other tokens from all spot trading on April 1, 2026. BYDFi issued an additional 'ST Warning' for LRC in May 2026, flagging it for potential delisting due to liquidity and compliance concerns. These successive delistings substantially reduced LRC's liquidity and visibility in the months immediately preceding the DEX closure.","heading":"LRC Token Delistings (Early 2026)","severity":"high","sources":[{"credibility":2,"name":"Upbit to Delist Loopring Over Transparency and Risk Issues — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/02/13/upbit-to-delist-loopring-over-transparency-and-risk-issues/"},{"credibility":2,"name":"Upbit & Bithumb to Delist Loopring ($LRC) — Coinpedia","type":"news_article","url":"https://coinpedia.org/crypto-live-news/upbit-bithumb-to-delist-loopring-lrc/"},{"credibility":2,"name":"Upbit to Delist Loopring Over Business Concerns — Phemex News","type":"news_article","url":"https://phemex.com/news/article/upbit-to-delist-loopring-lrc-over-business-concerns-60207"},{"credibility":2,"name":"LRC Faces Delistings and Market Volatility Amid Key Economic Events — AInvest","type":"news_article","url":"https://www.ainvest.com/news/lrc-faces-delistings-market-volatility-key-economic-events-2603/"}]},{"content":"Loopring was founded in 2017 by Daniel Wang, a software engineer with prior roles at Google and JD.com. An initial coin offering in August 2017 raised $45 million, though the majority of funds were returned to participants after China tightened ICO regulations; the remainder was used by the Loopring Foundation, a non-profit entity based in Shanghai. The Loopring protocol was first deployed on Ethereum mainnet in December 2019, making it the first zero-knowledge rollup exchange and payment protocol on Ethereum. The project helped demonstrate the viability of zk-rollup scaling and influenced the development of more capable successor networks including zkSync, Scroll, and StarkNet. Loopring reached a peak TVL of approximately $760 million in November 2021 during the broader DeFi bull market. By the time of the June 2026 shutdown, TVL had contracted to roughly $8 million — a decline of approximately 99%. The LRC token fell from its all-time high of approximately $3.75 to around $0.01, representing a decline of over 99% from peak. The Loopring Smart Wallet mobile application had already ceased operations on June 30, 2025, prior to the DEX shutdown. The protocol's founders co-founded Taiko Labs, a separate Ethereum scaling project, indicating the team had redirected focus to other ventures before the formal DEX closure.","heading":"Background and Historical Context","severity":"low","sources":[{"credibility":2,"name":"What Is Loopring & How Does It Work? — Kriptomat","type":"other","url":"https://kriptomat.io/cryptocurrency-prices/loopring-lrc-price/what-is/"},{"credibility":2,"name":"Interview with Daniel Wang CEO and Founder of Loopring Foundation — DeFi Prime","type":"other","url":"https://defiprime.com/loopring-protocol"},{"credibility":2,"name":"Loopring Wallet Closure Announcement — Loopring Protocol Medium","type":"official","url":"https://medium.com/loopring-protocol/loopring-wallet-closure-announcement-287400ff621b"},{"credibility":2,"name":"Loopring to cease wallet operations on June 30 — crypto.news","type":"news_article","url":"https://crypto.news/loopring-to-cease-wallet-operations-on-june-30/"},{"credibility":2,"name":"Daniel Wang — Co-Founder & CEO @ Taiko Labs — Crunchbase","type":"other","url":"https://www.crunchbase.com/person/daniel-wang-4"}]},{"content":"Current users of the Loopring DEX are required to take no action to receive their funds, as the team stated it will distribute all L2 balances directly to users' associated Ethereum Layer-1 addresses. However, several risks and caveats apply. First, users whose accounts hold balances below $10 will not receive a distribution and those assets are effectively lost. Second, users must trust the team's execution of the batch distribution process, as the normal self-custody exit mechanism has been disabled by smart contract upgrade; the protocol-level guarantee of trustless withdrawal no longer applies. Third, AMM liquidity positions are being converted to underlying tokens, which may result in different asset compositions than users expect. Fourth, the two-week discrepancy review window requires users to actively monitor the balance list published on X to verify their entries are correct. Fifth, the anticipated batch distributions are expected to increase selling pressure on LRC given that distributed tokens may be sold by recipients. The broader implication for DeFi is a precedent concern: a protocol that was specifically designed to eliminate operator trust is ending by requiring it, potentially informing how future zkRollup shutdowns are evaluated.","heading":"Implications for Users","severity":"medium","sources":[{"credibility":2,"name":"Loopring Shuts Down Its DEX Disabling the Trustless Exit It Pioneered — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/06/29/loopring-shuts-down-its-dex-disabling-the-trustless-exit-it-pioneered/"},{"credibility":2,"name":"Loopring Shuts Down All DEX Services, Citing Lack Of User Adoption — BitcoinWorld","type":"news_article","url":"https://bitcoinworld.co.in/loopring-shuts-down-dex-services/"},{"credibility":2,"name":"Loopring DEX Ceases All Trading Operations Following Permanent Sunset Announcement — CastleCrypto","type":"news_article","url":"https://castlecrypto.gg/news/loopring-dex-ceases-all-trading-operations-following-permanent-sunset-announcement/"}]}],"sources_used":[{"credibility":2,"name":"Loopring Shuts Down Its DEX Disabling the Trustless Exit It Pioneered — CryptoTimes","type":"news_article","url":"https://www.cryptotimes.io/2026/06/29/loopring-shuts-down-its-dex-disabling-the-trustless-exit-it-pioneered/"},{"credibility":2,"name":"Ethereum zkRollup project Loopring sunsets DEX — The Block","type":"news_article","url":"https://www.theblock.co/post/406492/loopring-sunsets-dex"},{"credibility":2,"name":"Loopring shuts down Ethereum's first zk rollup DEX after years of decline — crypto.news","type":"news_article","url":"https://crypto.news/loopring-shuts-down-ethereums-first-zk-rollup-dex-after-years-of-decline/"},{"credibility":2,"name":"Loopring Shuts Down Its Pioneering Ethereum zkRollup DEX — BanklessTimes","type":"news_article","url":"https://www.banklesstimes.com/articles/2026/06/29/loopring-shuts-down-its-pioneering-ethereum-zkrollup-dex/"},{"credibility":2,"name":"Loopring shuts down DEX — What went wrong for Ethereum's L2 pioneer?
