## Wallets

* [`wallet_sendPreparedCalls`](https://www.alchemy.com/docs/wallets/api-reference/smart-wallets/wallet-api-endpoints/wallet-send-prepared-calls) now returns `validUntil` for calls using a Gas Sponsorship policy, so you can see when sponsorship expires at submission time.
* [`wallet_getCallsStatus`](https://www.alchemy.com/docs/wallets/api-reference/smart-wallets/wallet-api-endpoints/wallet-get-calls-status) now checks a narrower block range for older calls and has lower latency on several chains, reducing unnecessary “not found” responses when tracking call status.
* Fixed incorrect ERC-20 gas-payment rates returned by [`wallet_prepareCalls`](https://www.alchemy.com/docs/wallets/api-reference/smart-wallets/wallet-api-endpoints/wallet-prepare-calls) for EntryPoint v0.6, helping ensure accurate sponsorship estimates.
* Added preliminary Glamsterdam support for the Ethereum Sepolia Bundler, so teams can begin testing compatibility ahead of the upgrade. [Learn more about the Bundler](https://www.alchemy.com/docs/wallets/transactions/low-level-infra/overview).

P2 Badge Use the public Polygon Amoy network name

For readers trying to identify the affected endpoint, Matic Testnet does not correspond to any supported public network name in this repository: the chain specification names this network Polygon Amoy (src/openrpc/chains/matic/matic.yaml:13), as do all previous Polygon testnet changelog entries. Publishing the internal/obsolete name makes this upgrade difficult to associate with the supported Polygon Amoy endpoint, so rename the network accordingly.

P2 Badge Identify the Robinhood upgrade as nitro-node

For users verifying which node binary changed, Robinhood is the network name rather than the upgraded component. Robinhood Mainnet upgrades are identified as nitro-node elsewhere in this changelog (2026-05-14.md:44 and 2026-08-20.md:39), and the immediately preceding Robinhood Chain Testnet entry records this same release as nitro-node v3.12.1-70fa99a (2026-10-08.md:35). Label this component as nitro-node so the release record accurately identifies the deployed software.
