Abstract, an Ethereum layer-2 network, says it will shut down on Dec. 15, 2026. In its Oct. 6 announcement, @AbstractChain told users to migrate their assets before that date or lose access to their funds.

The deadline tests a distinction that can disappear behind the phrase self-custody. A holder can retain ownership and the authority to approve transactions while losing the infrastructure needed to execute them. Cube, Inc., the company providing Abstract's services, makes that separation explicit in its updated terms: wind-down does not transfer assets to Cube or the other parties covered by its terms, but the end of normal processing ends transfer access through discontinued services.

A completed exit requires a supported asset route, access to the authorizing wallet, a controlled destination and every required processing or claim step.

@AbstractChain's announcement directs users to the Migration Hub at migrate.abs.xyz or the native bridge at native-bridge.abs.xyz. The public Migration Hub repeats the Dec. 15 notice and lists Native Bridge, Stargate, Relay, Jumper and project-specific instructions.

The general terms identify migration.abs.xyz as the official Hub and bridge.abs.xyz as the existing bridge interface. The Hub at that address also displays the shutdown notice and alternative bridge links. However, the announcement and terms name different interfaces; their addresses alone do not establish interchangeable routes. The Hub links also do not supply a complete map showing which token, NFT or application position can use each one.

The existing bridge interface offers wallet connection, token selection, route priority, gas and slippage controls, with 0x attribution.
