Overview

The recently introduced API method bor_sendRawTransactionConditional by the Polygon client Bor is only functional if the caller has a direct connection to a validator node RPC. For obvious security reasons, validators cannot open their RPCs to the world, and the new method becomes unusable.

PFL proposes a very similar API method through its relay, pfl_sendRawTransactionConditional, for any and every AA bundler to be able to access and take advantage of the conditional bundle feature.
