Bundled Post-fund

Post-funding only works on certain chains that: 1) do not have a "base fee" and 2) have builders / bundle functionality. Currently we only support this method on BSC.

Instead of paying the fee payer (like in Pre-fund) we simply pay the builder/validator an extra tip to include the sponsoring transaction.

Advantages:

  • Simple - "Just works with all types of wallets"

  • More gas efficient then Pre-fund

Disadvantages

  • Network support (only BSC)
