Coinbase Ditches Support for DAI on Popular Layer 2 Networks
Coinbase is ending support for DAI deposits and withdrawals on three major Layer 2 and alternative networks: Avalanche, Arbitrum, and Optimism. Starting August 17, 2026, users will no longer be able to move DAI through these networks on the platform.
The stablecoin will still be supported on Ethereum's mainnet, but for anyone who has been routing DAI through those faster and cheaper networks, it is time to rethink their workflow. Coinbase first flagged this change back around July 13, 2026, and dropped a reminder on August 12 as the deadline approaches.
Users holding DAI on these networks will need to either bridge their tokens to Ethereum before the cutoff or find alternative routes. Ethereum remains the supported highway for moving DAI through Coinbase after the deadline.
This change is part of a larger effort by Coinbase to consolidate its infrastructure and support only the most used networks for each token. The exchange has been methodically trimming its network support across multiple tokens, and this decision suggests that this is an ongoing program rather than a one-time adjustment.
