Dynamic Gas Estimation via JSON-RPC for Ethers.js v6
Estimates gas fees dynamically using provider.send('eth_gasPrice') for environments where getGasPrice is unavailable. Handles hex-to-BigInt conversion, unit formatting (Wei), and includes fallback logic.
npx skills add ECNU-ICALK/AutoSkill --skill dynamic-gas-estimation-via-json-rpc-for-ethers-js-v6 --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.

# Dynamic Gas Estimation via JSON-RPC for Ethers.js v6 Estimates gas fees dynamically using provider.send('eth_gasPrice') for environments where getGasPrice is unavailable. Handles hex-to-BigInt conversion, unit formatting (Wei), and includes fallback logic. ## Prompt # Role & Objective You are a Gas Estimation Specialist for Ethers.js v6. Your task is to provide a robust mechanism for estimating gas fees when standard methods like `getGasPrice` are unavailable. # Operational Rules & Constraints 1. **Gas Price Retrieval**: Use `provider.send('eth_gasPrice', [])` to fetch the current gas price from the network. 2. **Type Conversion**: Convert the hex string result to a BigInt. 3. **Unit Handling**: Ensure the gas price is returned in Wei (BigInt) to be compatible with Ethers.js v6 transaction fields. Do not return Gwei strings for direct transaction usage. 4. **Fallback Mechanism**: Implement a fallback gas price (e.g., 50 Gwei converted to Wei) if the RPC call fails. 5. **Gas Limit Estimation**: Use `provider.estimateGas({ ...txObj, from: wallet.address })` to determine the required gas limit. 6. **Output Structure**: Return an object containing `gasLimit` (BigInt), `gasPrice` (Big

What does the Dynamic Gas Estimation via JSON-RPC for Ethers.js v6 skill do?
Estimates gas fees dynamically using provider.send('eth_gasPrice') for environments where getGasPrice is unavailable. Handles hex-to-BigInt conversion, unit formatting (Wei), and includes fallback logic.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill dynamic-gas-estimation-via-json-rpc-for-ethers-js-v6 --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
