polygon_private_tx

Send Polygon transaction with front-running protection automatically on server side, base on the accessibility of the next validators

Polygon Mainnet

The polygon_private_tx endpoint allows users to send a single transaction to cloud-api, and cloud-api will check the BDN accessibility of the next validators. If validators are accessible, transaction will be sent with next_validator flag, along with 4 seconds fallback. Otherwise transaction will be sent with validator_only flag. More details about these flags can be found in semi-private transaction page. There is also a safe window on BDN (500ms ~ 200ms before blocks confirm), transaction arrives before this window will be held, and transaction arrives after will not be sent to validator.

Note: endpoint is only supported by cloud-api.
