Smart Accounts
SemiModularAccount7702v1.1.0 is now deployed on all supported networks and available in the aa-sdk. This version adds a fallback signature path so signatures from the underlying EOA are accepted alongside the account's default signer.SemiModularAccount7702v1.1.0 is now the default delegation used when creating new 7702 accounts via the Wallet APIs. Existing on-chain delegations keep their current version and are not upgraded in place unless a new version is explicitly requested at deploy time.
Gas Manager
- Added a step-by-step guide for paying gas with any ERC-20 token, covering how to price the token, configure the ERC-20 policy on the paymaster, and submit sponsored transactions from your app.
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.
