One of the most common questions about Matic Bridge is how much it costs. The answer is straightforward: the bridge itself charges a 0% protocol fee. The only cost you pay is the Ethereum gas fee required to execute the lock transaction on the Ethereum mainnet smart contract.

Ethereum Gas Fees for Bridging

Ethereum gas fees fluctuate based on network demand. During low-activity periods (typically late night UTC or weekends), gas fees for a bridge transaction can be as low as $0.50–$1.50. During periods of high DeFi activity or NFT minting events, fees may temporarily spike to $5–$20. To minimize costs, use gas fee tracking tools to bridge during off-peak hours.

• Low congestion: $0.50 – $1.50 per bridge transaction
• Normal conditions: $1.50 – $5.00 per bridge transaction
• High congestion: $5.00 – $20.00+ per bridge transaction
• Withdrawal from Polygon: additional ~$0.50–$2 Ethereum fee to claim

Polygon Transaction Costs

Once your tokens arrive on Polygon, transaction fees are dramatically lower. A typical token swap or DeFi interaction on Polygon costs between $0.001 and $0.01, compared to $5–$50 for the same transaction on Ethereum. This cost difference is the primary reason Polygon has attracted over $1 billion in total value locked and hundreds of DeFi applications.

Polygon transactions are up to 10,000 times cheaper than equivalent Ethereum transactions, making it ideal for frequent DeFi interactions and high-volume trading strategies.

For users bridging large amounts, the one-time Ethereum gas cost is easily offset by the savings on subsequent Polygon transactions. A single Ethereum gas fee for bridging can cover thousands of Polygon interactions at current fee rates.
