What are blockchain gas fees?
Gas fees are the cost you pay to have the blockchain network process your transaction. They work as an incentive for validators or miners who confirm operations.
The cost depends on three factors: the gas price (measured in Gwei on EVM networks), the gas limit (the amount of computational work the operation requires), and network congestion at the time.
Why do costs vary between networks?
Each blockchain has its own architecture, consensus mechanism and processing capacity. Layer 2 networks like Arbitrum, Optimism and Base process transactions off the Ethereum mainnet and batch them, significantly reducing costs. Solana uses a different consensus mechanism (Proof of History) that enables thousands of transactions per second at minimal cost.
Networks like Polygon and BNB Chain offer a balance between security and low costs, ideal for DeFi applications with high transaction volume.
Tips to reduce gas fees
- Choose the right time: gas fees drop during low-activity periods (weekends and early morning UTC).
- Use Layer 2 networks: Arbitrum, Optimism, Base or zkSync can reduce your costs by 90% to 99%.
- Batch operations: if you need multiple transactions, use contracts that execute them in batch.
- Optimize your smart contracts: a well-optimized contract consumes less gas. At Beltsys Labs we specialize in developing efficient smart contracts.
