Polygon PoS is supported in both the Wallet APIs and the Low-Level Infra APIs. It has access to capabilities such as EIP-7702 support, gas sponsorship, transaction batching, and more.
The Polygon PoS network lacks a reliable private mempool for submitting transactions through. This leads to a few restrictions that are enforced to protect the transaction infrastructure and users from front-running attacks.
Transactions are submitted to the Polygon mainnet and Polygon Amoy public mempools. No MEV protection is offered for users on Polygon PoS.
On Polygon mainnet, transactions submitted through either the Wallet APIs or the Low-Level Bundler API must use the Gas Manager.
We will begin enforcing this on 01/30/2026.

This is done to ensure the following:
- The onchain account itself is not restricted in any way. If the user wishes to upgrade/delegate their account or use their account with another provider, they can.
- All transactions submitted through the transaction infrastructure are protected from front-running as the Gas Manager requires transactions to be submitted through trusted EOAs.
On Polygon mainnet and Polygon Amoy, transactions that are sponsored by the Gas Manager must be submitted through either the Wallet APIs or Low-Level Bundler API.
This is due to the new logic in the Gas Manager contracts that requires transactions to be submitted through trusted EOAs.
We will begin enforcing this on 01/30/2026.

Users that attempt to use a sponsored transaction with a different API may see the following Solidity error:
error SenderNotAllowed(address sender);
