Fee Juice

Fee Juice is an enshrined asset in the Aztec network that is used to pay fees.

It has several important properties:

  • It is fungible
  • It cannot be transferred between accounts on the Aztec network
  • It is obtained on Aztec via a bridge from Ethereum
  • It only has public balances

All transactions on the Aztec network have a non-zero transaction_fee, denominated in FPA, which must be paid for the transaction to be included in the block.

When a block is successfully published on L1, the sequencer is paid on L1 the sum of all transaction fees in the block, denominated in FPA.
