節省 Gas 費用的技巧
Transact during off-peak hours
Gas fees tend to be lowest on weekends and during nighttime UTC (roughly 00:00–06:00 UTC). Network congestion drops significantly when US and European markets are closed. Use the current fee tier above as your real-time signal: if you're seeing 'Low' or 'Standard' readings, it's generally a good time to transact.
Use Layer 2 networks
Networks like Arbitrum, Optimism, and Base offer 10–100x lower fees while maintaining Ethereum's security guarantees.
Set a custom gas limit
Most wallets let you set a max fee. Use the 'Low' tier if you're not in a rush — your transaction will still confirm, just more slowly.
Batch transactions
If you have multiple transfers, some protocols let you batch them into a single transaction, especially useful for NFT minting and token approvals.
什麼是 Ethereum Gas 費用?
Gas 費是用戶支付給以太坊區塊鏈的費用,用於補償處理和驗證交易所需的計算能量。費用以「Gwei」計價——ETH 的最小單位之一,其中 1 Gwei = 0.000000001 ETH。以太坊上的每項操作都需要特定的計算工作量,以「gas 單位」衡量。總費用計算方式為:Gas 單位 × Gas 價格(Gwei)。
EIP-1559 如何改變 Gas 費機制
The August 2021 EIP-1559 upgrade introduced a two-component fee model:
基本費(已銷毀)
由協議決定並根據需求自動調整的費用。此金額將被永久銷毀,使 ETH 在高使用量期間具有通縮效應。基本費每個區塊的變動幅度不超過 ±12.5%。
優先小費(支付給驗證者)
可選的小費,用於激勵驗證者優先打包交易。在網絡擁堵較低時,1–2 Gwei 通常已足夠。
各交易類型的 Gas 費用
| 交易 | Gas 單位 | @ 20 Gwei | @ 100 Gwei |
|---|---|---|---|
| ETH Transfer | 21,000 | ~$1.50 | ~$7.50 |
| ERC-20 Transfer | 65,000 | ~$4.50 | ~$23 |
| Uniswap Swap | 150,000–300,000 | ~$10–21 | ~$52–105 |
| NFT Mint | 100,000–250,000 | ~$7–17 | ~$35–87 |
| Aave Deposit | 200,000–400,000 | ~$14–28 | ~$70–140 |
