Dune SIM is closing on August 1, 2026.​ Users relying on SIM for balances, transactions, or DeFi positions need to migrate to Zerion API.​

Key details:

  • Several large teams have already completed the switch
  • Migration guide and codemod available to streamline the process
  • Setup can be completed in a couple of hours

This follows Zerion's earlier decision to wind down ZER Network by July 31, 2026, as the company focuses resources on its API and wallet products.​
