Origin Chain Gas Fee ($) origin_gas_fee_usd

L1 gas to approve and deposit tokens

Bridge Protocol Fee (%) bridge_protocol_fee_pct

Across, Stargate, or Hop protocol fee

Destination Gas Refuel ($) dest_gas_drop_usd

Optional native gas subsidy credited on destination chain

Calculated Output Metrics

Net Amount Received on Destination $4,983.50

Total Bridge Toll & Gas Paid $16.50

Effective Bridge Cost Percentage 0.33%

Protocol Liquidity Fee $3.00

Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Total Bridge Fee = Origin Gas + Operator Fixed Fee + Protocol % + Destination Mint Gas

Step-by-Step Mathematical Derivation

Protocol Liquidity Fee

Protocol Fee = $5,000 × 0.06% = $3.00.

Destination Gas Refuel Deductions

Destination Gas = $5.00. Net Token Credit = $5,000 - $3.00 - $5.00 = $4,992.00.

All-In Cross-Chain Cost

Total Expense = Origin Gas ($8.50) + Protocol Fee ($3.00) + Dest Gas ($5.00) = $16.50 (0.33% total toll).

Frequently Asked Questions

What is the difference between Burn-and-Mint and Lock-and-Mint bridges? +

Lock-and-Mint bridges lock collateral in a source chain multisig and mint wrapped tokens on the destination (high smart contract hack risk). Burn-and-Mint (like Circle CCTP) burns native USDC natively on source and mints real native USDC on destination with zero wrapper risk.

Why do cross-chain bridges get hacked so frequently? +

Bridges custody massive multi-hundred-million-dollar honey pots of locked assets secured by complex multi-chain relayer nodes, making verification oracle bugs catastrophic targets for state-sponsored exploits.
