Treanor Devlin Brown is currently investigating the following episodes and assessing whether a lawsuit should be filed. If you lost funds and would like information about any of these matters, contact us.
Arbitrum (ARB) Token Investigation
Treanor Devlin Brown is investigating potential claims on behalf of investors who purchased Arbitrum’s $ARB token and suffered significant financial losses.
What Happened
$ARB, the governance token of the Arbitrum Layer 2 network, launched in March 2023 and reached an all-time high of approximately $2.40 in January 2024. Since then, the token’s price has declined by more than 95%, falling below $0.10 by early 2026. Investors who purchased $ARB during or after its initial distribution have suffered substantial losses.
Treanor Devlin Brown is examining whether this dramatic price collapse was caused or exacerbated by potential misconduct, including insider selling, token unlock practices and potential market manipulation.
Who Should Contact Us
If you purchased $ARB tokens and suffered losses, we want to hear from you. You may have information relevant to our investigation, and you may have legal claims. There is no cost or obligation to you.
Movement Labs
Movement Labs listed the MOVE token on Binance on December 9, 2024. The next day, approximately 66 millions MOVE tokens were sold off, erasing approximately $2.5 billion in market value. TDB Law is investigating published reports of market manipulation and potential litigation against those responsible.
Mantra
On April 13, 2025 Mantra’s OM token plummeted in price from approximately $6.21 to below $.49 within a day, marking a loss of 92% in value. TDB Law is investigating possible market manipulation — both with respect to the collapse of the price and whether it had artificially been propped up before then.
