Hedera to End Smart Contract Calls Inside Atomic Batch Transactions
- —From September 2026, a batch may include at most one smart contract call, in the final position
- —Smart contract calls as inner transactions of an atomic batch will be removed in March 2027
- —Batches containing only native Hedera service operations remain unaffected
- —Developers are advised to move logic into a contract, use HTS/HAS/HSS system contracts, or submit transactions sequentially
Why it matters: The change affects Hedera applications that rely on atomic batches with smart contract calls and requires migration before March 2027.
