Transactions & Fees

TL;DR

• Supported tx types: Legacy/2930/1559. 4844/7702 are unsupported.
• Fee model is base fee + priority fee (with constraints).

Fee Model

• compute_next_base_fee updates next block base fee
• compute_effective_gas_price computes effective price

Pitfalls

• Sending tx with mismatched chain id
• Violating priority/max fee consistency constraints
