is a Paris-based DeFi stablecoin protocol founded in 2022 by former French politician Pierre Person and co-founders Adli Takkal Bataille and Hugo Salle de Chou. The protocol issues USD0, a stablecoin collateralized by tokenized US Treasury Bills, alongside USD0++, a four-year locked bond derivative that suffered a significant depeg event in January 2025 after the team unilaterally changed redemption rules without adequate community notice. A smart contract arbitrage exploit was also detected and paused in May 2025, and USD0++ tokens were stolen in an unrelated third-party hack of Zoth Protocol in March 2025.","timeline":[{"date":"2022-01-01","event":"Usual Labs co-founded by Pierre Person, Adli Takkal Bataille, and Hugo Salle de Chou","source":""},{"date":"2024-04-17","event":"Usual Labs raises $7 million seed round led by IOSG Ventures and Kraken Ventures","source":"CoinDesk","source_url":"https://www.coindesk.com/business/2024/04/17/defi-firm-usual-labs-raises-7m-round-led-by-kraken-ventures-and-iosg"},{"date":"2024-11-15","event":"USUAL governance token launches on Binance Launchpool; farming period begins","source":"Binance","source_url":"https://www.binance.com/en/square/post/11-14-2024-binance-launches-usual-usual-on-launchpool-with-pre-market-trading-to-follow-16224040648377"},{"date":"2024-11-19","event":"USUAL/USDT pre-market trading begins on Binance","source":"CoinGape","source_url":"https://coingape.com/binance-launchpool-to-list-usual-usual-with-pre-market-trading/amp/"},{"date":"2024-12-01","event":"Usual raises $10 million Series A led by Binance Labs and Kraken Ventures","source":"Crowdfund Insider","source_url":"https://www.crowdfundinsider.com/2024/12/234605-stablecoin-project-usual-raises-10m-series-a-led-by-binance-labs-kraken-ventures/"},{"date":"2024-12-20","event":"USUAL governance token reaches all-time high of approximately $1.61-$1.64","source":"CoinGecko","source_url":"https://www.coingecko.com/en/coins/usual"},{"date":"2025-01-01","event":"Usual Protocol TVL peaks at approximately $1.87 billion","source":"DeFiLlama / CoinDesk","source_url":"https://defillama.com/protocol/usual"},{"date":"2025-01-09","event":"Usual Protocol announces dual-path exit change, lowering USD0++ unconditional redemption floor to $0.87; market panic begins","source":"The Block","source_url":"https://www.theblock.co/post/333995/usual-money-protocol-update"},{"date":"2025-01-10","event":"USD0++ falls below $0.90 on Curve Finance; USUAL token drops 17%; TVL falls below $1.6 billion; widespread community backlash including from Aave founder Stani Kulechov","source":"CoinDesk","source_url":"https://www.coindesk.com/markets/2025/01/10/red-hot-de-fi-platform-usual-faces-backlash-as-protocol-update-triggers-sell-off"},{"date":"2025-01-13","event":"Usual activates revenue switch, distributing protocol earnings to USUALx stakers; introduces 1:1 early unstaking with reward forfeiture","source":"Usual Blog","source_url":"https://usual.money/blog/revenue-switch-a-new-dawn-for-usualx-holders"},{"date":"2025-03-06","event":"Zoth Protocol, which holds USD0++ collateral, loses $285,000 in Uniswap V3 liquidity pool exploit","source":"Crypto Times","source_url":"https://www.cryptotimes.io/2025/03/21/zoth-protocol-loses-8m-in-latest-defi-exploit/"},{"date":"2025-03-21","event":"Zoth Protocol hacked for $8.4 million via compromised deployer private key; attacker withdraws $8.45 million in USD0++ tokens and converts to ETH","source":"Halborn","source_url":"https://www.halborn.com/blog/post/explained-the-zoth-hack-march-2025"},{"date":"2025-05-27","event":"Usual USD0++ Investment Vault arbitrage exploit detected by BlockSec Phalcon; attacker extracts approximately $43,000 via flash loan arbitrage between USD0++ and USD0; vault contracts paused; no user funds lost","source":"Usual / CoinEdition","source_url":"https://coinedition.com/blocksec-stops-hack-attempt-usual-protocol-prevents-asset-loss/"}]},"v":1}
