Quick Facts
- ArbiTract is the official plugin used for auditing gas estimation errors on Arbitrum.
- Fixing gas estimation errors on Arbitrum requires identifying and adjusting incorrect gas prices.
- The most common error is incorrect calculation of gas prices, which can lead to overpayment or underpayment.
- ArbiTract can help in identifying such errors by running a simulation of your TX.
- If gas price is low, your TX may be stuck and not mined, leading to potential losses.
- Correcting the gas price in the TX may require adjusting the gasLimit and gasPrice in your tx object.
- The Arbitrum network uses a proof-of-stake consensus algorithm, unlike Ethereum which uses proof-of-work.
- The estimated gas prices are calculated based on the gas used by the TX and the current gas price.
- Gas estimation errors on Arbitrum can also be caused by malicious validators, which can manipulate gas prices.
- Regularly monitoring your TX and gas prices is crucial to avoid such errors.
Fixing Gas Estimation Errors on Arbitrum
As a trader on TradingOnramp.com, you’re likely familiar with the concept of gas estimation. However, on Arbitrum, a popular layer 2 scaling solution, gas estimation errors can be a frustrating obstacle. In this article, we’ll explore the causes of gas estimation errors and provide practical steps to fix them.
Gas estimation errors occur when the estimated gas cost of a transaction exceeds the actual gas cost, resulting in failed transactions and wasted time. To understand why this happens, let’s dive into the basics of gas estimation.
Arbitrum’s unique architecture and gas estimation algorithms can lead to errors, especially during periods of high network congestion.
Common Causes of Gas Estimation Errors
Before we dive into fixing gas estimation errors, let’s identify the common causes:
- Insufficient gas limits
- Incorrect gas price
- Network congestion
- Smart contract complexity
| Cause | Effect |
|---|---|
| Insufficient gas limits | Transaction reverts, wasted gas |
| Incorrect gas price | Transaction fails, or settles at unfavorable price |
| Network congestion | Transactions take longer to process, increasing gas costs |
| Smart contract complexity | Increased gas costs, higher risk of estimation errors |
To illustrate this, consider a real-life example: during the OpenSea NFT minting frenzy, many users experienced gas estimation errors due to network congestion and insufficient gas limits.
Practical Steps to Fix Gas Estimation Errors
Now that we’ve identified the common causes, let’s move on to practical steps to fix gas estimation errors:
- Monitor gas prices: Keep an eye on current gas prices using tools like EthGasWatch or GasNow.
- Adjust gas limits: Increase gas limits for complex transactions or during periods of high network congestion.
- Use gas estimation tools: Utilize tools like EthGasWatch or GasNow to estimate gas costs.
- Optimize smart contracts: Simplify smart contract logic to reduce gas costs and estimation errors.
Here’s a list of best practices to keep in mind:
- Use Web3 tools to monitor gas prices and adjust gas limits accordingly.
- Implement smart contract optimization techniques to reduce gas costs.
- Consider using alternative gas estimation algorithms for more accurate estimates.
Advanced Techniques for Fixing Gas Estimation Errors
For more advanced traders, let’s explore some additional techniques:
- Gas estimation algorithms: Experiment with different gas estimation algorithms, such as the ERC-20 gas estimation algorithm.
- Off-chain gas estimation: Use off-chain gas estimation methods, such as machine learning-based gas estimation.
| Algorithm | Description | Pros | Cons |
|---|---|---|---|
| ERC-20 gas estimation | Standard gas estimation algorithm for ERC-20 tokens | Simple, widely adopted | Less accurate for transactions |
| EIP-1559 gas estimation | Gas estimation algorithm for EIP-1559 compliant chains | More accurate, flexible | More complex, less widely adopted |
