Max fees represent the highest possible fee amount you will pay to broadcast this transaction. The final fees, calculated once the transaction is approved by the last Operator, might be lower, but will never exceed that amount. We recommend estimating max fees through our fee estimation endpoint prior to creating the transaction request. See https://help.vault.ledger.com/developer-portal/content/transactions/tx/ for details.For Solana and Polkadot, max_fees field must be ignored.

Pattern: ^[0-9]*(\.[0-9]+)?$
