+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](/docs/wallets/transactions/using-eip-7702#choose-the-delegation-version).

-* `SemiModularAccount7702` v1.1.0 is now deployed on all supported networks and available in the [aa-sdk](https://github.com/alchemyplatform/aa-sdk). This version adds a fallback signature path so signatures from the underlying EOA are accepted alongside the account's default signer.
-* Starting September 14, `SemiModularAccount7702` v1.1.0 will be 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.

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.

For implementation details, see the [Send Transactions](/docs/wallets/transactions/send-transactions) guide.
+## Choose the delegation version
+
+For an account that is already delegated, Wallet APIs continue using its recorded delegate. For a new account, Wallet APIs use the current default unless you explicitly request a supported version in the `eip7702Auth` capability.
+
+For example, request v1.1.0 with `wallet_prepareCalls`:
+
+```json
+{
+ "capabilities": {
+ "eip7702Auth": {
+ "delegation": "ModularAccountV2",
+ "version": "v1.1.0"
+ }
+ }
+}
+```
+
+Use `"version": "v1.0.0"` to keep a new account on v1.0.0. You can also pass a supported `SemiModularAccount7702` address directly as `delegation`; see [Smart contract deployments](/docs/wallets/smart-contracts/deployed-addresses#modular-account-v2) and use only the rows named `SemiModularAccount7702`.
+
+
+ Explicitly requesting a version re-delegates an existing account when it currently uses a different version. After delegation, later calls continue using the account's recorded delegate unless you explicitly request another version.

## How to use non-7702 mode
If you need to use a traditional wallet instead of EIP-7702, opt out of the default 7702 behavior by calling `wallet_requestAccount` first.
