FeeCalculator

Calculates transaction fees using midnight-ledger's fee calculation.

Fee Calculation Process:

1. Deserializes transaction from SCALE-encoded hex

2. Deserializes ledger parameters from SCALE-encoded hex

3. Calls transaction.fees_with_margin(params, margin)

4. Adds 1% safety overhead

5. Returns total fee in Specks

Safety Overhead:

• 1% of base fee (conservative buffer)

• feesWithMargin() already includes block-based margin

Fee Blocks Margin:

• Default: 5 blocks (typical value)

• Accounts for blockchain price changes between transaction creation and confirmation

• Higher margin = higher fee, but more safety against rejection
