There is not currently a date set to deprecate support for EntryPoint v0.6 but deprecation is planned sometime in 2026. Ensure that you have migrated to EntryPoint v0.7 or v0.8 by that time.

## Ethereum Sepolia and Glamsterdam

### What is the gas cap on Ethereum Sepolia after Glamsterdam?

Ethereum Sepolia activated the Glamsterdam hard fork on October 6, 2026. Glamsterdam introduces [EIP-8037](https://eips.ethereum.org/EIPS/eip-8037) state gas, which the bundler doesn't fully support above the [EIP-7825](https://eips.ethereum.org/EIPS/eip-7825) transaction gas cap of 16,777,216 gas. To stay under it, the bundler enforces these limits on Ethereum Sepolia:

P2 Badge Distinguish execution gas from total transaction gas

For Glamsterdam transactions that use the new state-gas reservoir, 16,777,216 is only the EIP-7825 execution-gas ceiling, not the total transaction gas cap: EIP-8037 permits tx.gas up to 2^32−1 so additional state gas can exceed that boundary. Calling this a transaction gas cap obscures the exact capability that the bundler currently lacks and can lead readers to mistake an Alchemy limitation for a protocol-wide limit; describe it as the execution-gas cap instead.

* Bundles can use at most 16,777,216 gas.
* Gas estimation is capped at 16,000,000 gas.
* `verificationGasLimit` is capped at 10,000,000 gas.

UserOps that need more gas than these limits can't be estimated or bundled on Ethereum Sepolia. We're working to support larger state gas before Glamsterdam reaches mainnet.

The Bundler APIs are a collection of JSON-RPC endpoints for working with transactions. Below are the available endpoints and the corresponding docs for each of them.

<Warning>
Ethereum Sepolia activated the Glamsterdam hard fork on October 6, 2026. The bundler caps gas on Ethereum Sepolia until it supports larger state gas. See [the gas cap on Ethereum Sepolia](/docs/wallets/reference/bundler-faqs#what-is-the-gas-cap-on-ethereum-sepolia-after-glamsterdam) for details.
