Hyperliquid will remove the userDexAbstraction info endpoint during its upcoming network upgrade, as announced on its official X account on October 28. The endpoint, part of the outdated HIP-3 DEX abstraction layer, is being phased out as the protocol shifts to a modern account abstraction model. Developers relying on the endpoint must update their tools before the blockchain upgrade. No exact timeline has been shared.

Hyperliquid will remove the userDexAbstraction info endpoint in its next network upgrade, the protocol confirmed via its official X account on October 28.

The endpoint was a legacy component tied exclusively to the old HIP-3 DEX abstraction layer. It is being deprecated as Hyperliquid completes its migration to a more modern account abstraction architecture — a system designed to replace the original HIP-3 framework across the protocol.

No user action is required for wallets or standard trading activity. Developers and teams running custom tooling that queries the userDexAbstraction endpoint directly will need to update their integrations before the upgrade ships. The protocol has not announced a specific upgrade date as of this writing.

The change is consistent with Hyperliquid’s broader pattern of deprecating HIP-3 components as its account abstraction rollout progresses. This is a routine infrastructure cleanup — removing an obsolete API surface rather than altering any trading logic, settlement mechanics, or user-facing functionality.

Frequently Asked Questions

What is the userDexAbstraction endpoint and who used it?

The userDexAbstraction info endpoint was an API component specific to Hyperliquid’s old HIP-3 DEX abstraction layer. It was primarily relevant to developers building custom integrations or tooling on top of Hyperliquid — not to standard traders or wallet users.

What replaces the userDexAbstraction endpoint on Hyperliquid?

Hyperliquid’s modern account abstraction system replaces the legacy HIP-3 endpoint. The newer architecture is designed to offer broader and more flexible on-chain account management capabilities compared to the original DEX abstraction framework.

When will the Hyperliquid network upgrade removing this endpoint go live?

As of October 28, 2026, Hyperliquid has not announced a specific date for the upgrade. Developers should monitor official Hyperliquid channels and update any tooling querying the userDexAbstraction endpoint ahead of the next scheduled network upgrade.
