According to Charles | dYdX on Twitter, ethDYDX token holders must bridge their tokens before the official bridge closure to maintain access and liquidity. Traders are advised to check with their crypto exchanges to ensure bridging is completed, as some platforms may not have performed this step automatically. This deadline impacts trading volume and price discovery for DYDX, as unbridged tokens may lose utility after the bridge closes (source: Charles | dYdX via Twitter, beincrypto.com). Timely action is critical for crypto traders seeking uninterrupted trading and avoiding potential loss of asset value.
