Aster Tightens API Access For New Users

Aster (@Aster_DEX), the decentralized perpetual exchange built on BNB Smart Chain, is tightening access to its authenticated API for new users. From September 7, anyone seeking to use key V3 endpoints will first need to make a deposit from their linked main wallet before gaining access.

What Is Changing and Who Is Affected

The new requirement applies specifically to authenticated Spot V3 and Futures V3 endpoints. All authenticated Spot V3 and Futures V3 endpoints, covering account, order, trade, and other USER_DATA and TRADE endpoints, are only accessible after the main wallet linked to the Aster account has completed a deposit. This covers the endpoints developers rely on for account management, order activity, and trading operations.

The change is limited to new users. Those already active on the platform are not affected, and neither are public market data endpoints. Agent Wallet and Builder endpoints, and public market data endpoints, are unaffected.

Context: Aster's Ongoing API Transition

The deposit requirement is the latest step in a broader shift toward Aster's V3 API model. Aster has evolved from a traditional API key model to a Web3-aligned signer model in V3. The Pro API (V3) is built on Aster L1 with Web3-native authentication, offering faster order execution, on-chain trade traceability, nonce replay-attack protection, and quicker cancellations.

Earlier this year, Aster phased out V1 API key creation entirely. New V1 API key creation has not been supported since March 25, 2026, though existing V1 keys continue to work. Starting March 16, V1 latency began to gradually increase, reaching approximately 200 milliseconds by March 18.

Aster has urged new users to complete the required deposit before attempting any restricted API requests to avoid disruptions to their integrations.
