| ## Wallets | ||
|
|
||
| **Wallet APIs** | ||
|
|
||
| * SemiModularAccount7702 v1.1.0 is now supported on all networks. New v1.1.0 delegations can be requested on any supported network without a per-network opt-in. | ||
| * Improved the error returned when attempting to use EIP-7702 on Monad. Requests where 7702 is disabled now surface a clear, actionable error instead of an opaque failure. | ||
|
|
||
| **Solana** | ||
|
|
||
| * Added support for pre-funding rent during composed account creation. Gas sponsorship now correctly funds rent for accounts created via Transfer + Allocate + Assign flows (for example, associated token accounts, Anchor init, and Metaplex), so these sponsored user operations no longer fail preflight. | ||
|
|
||
| **Rundler** | ||
|
|
||
| * Various improvements to Rundler retry logic to make bundle submission more resilient under transient upstream errors. | ||
|
|
||
| ## Developer Experience | ||
|
|
||
| **Usage API** | ||
|
|
||
| * The Usage API is now generally available under the Admin API. You can pull Alchemy usage data programmatically, without the dashboard or CLI: | ||
| * [GET /v1/usage/summary](https://www.alchemy.com/docs/admin-api/usage/get-usage-summary) returns current billing-period totals plus rolling 7-day, 30-day, and month-to-date usage in compute units and USD, along with usage cap status and headroom. | ||
| * [POST /v1/usage/time-series](https://www.alchemy.com/docs/admin-api/usage/get-usage-time-series) returns usage in hourly or daily buckets, filterable by product, app, network, and method, and groupable by any one of them. | ||
