Wallet APIs: EIP-7702 default changes September 21
Beginning September 21, 2026, new EIP-7702 accounts created through wallet_prepareCalls or wallet_requestAccount will delegate to SemiModularAccount7702 v1.1.0 by default on every supported network. Existing accounts are unaffected: they keep their recorded delegate and do not need to sign a new authorization.
If your application validates or recognizes accounts by delegate address or accountId(), add v1.1.0 to the accepted set before the rollout. Both versions remain supported, so accept both rather than replacing v1.0.0. You can opt in to v1.1.0 now or explicitly keep new accounts on v1.0.0.
Smart Accounts
SemiModularAccount7702v1.1.0 is now deployed on all supported networks and available in the aa-sdk. It adds support for standard EOA signatures through ERC-1271, improving compatibility with Permit2 and similar applications without introducing a new signer or authority path. The release was audited by Octane.- Starting September 21, v1.1.0 will be the default delegation for new EIP-7702 accounts created through Wallet APIs. Existing accounts keep their recorded version unless another version is explicitly requested.

Admin API
- App and chain management endpoints are now documented in the Admin API reference. You can programmatically create, update, and delete Alchemy apps, manage each app's network, origin, and IP allowlists, and list supported chains — everything the Alchemy Dashboard lets you do, callable from your own tooling with an access key. See the Admin API Quickstart for a full end-to-end example.
