Etherscan Gas API v2 Integration

Overview

The deployment cost estimation system now uses the correct Etherscan Gas API v2 endpoint for accurate gas price retrieval.

API Endpoint

Correct Endpoint: https://api.etherscan.io/v2/api?chainid=1&module=gastracker&action=gasoracle&apikey=YourApiKeyToken

Response Format

{
  "status": "1",
  "message": "OK",
  "result": {
    "LastBlock": "23788262",
    "SafeGasPrice": "0.111829336",
    "ProposeGasPrice": "0.11182936",
    "FastGasPrice": "0.123012296",
    "suggestBaseFee": "0.111829336",
    "gasUsedRatio": "..."
  }
}

Integration

Gas Price Sources (Priority Order)

MetaMask (via ETHEREUM_MAINNET_RPC)
Etherscan Gas API v2 (via ETHERSCAN_API_KEY)
Default RPC (fallback)

Methodology

Conservative Gas Price = MIN(MAX(MetaMask Gas, Etherscan Gas), 2.5 gwei)

Fetches from both MetaMask and Etherscan
Selects the highest price
Caps at 2.5 gwei maximum

Usage

Get Conservative Gas Price

./scripts/deployment/get-conservative-gas-price.sh

Calculate Costs

./scripts/deployment/calculate-conservative-costs.sh

Test API

./scripts/deployment/test-etherscan-gas-api.sh

Configuration

Add to .env:

ETHERSCAN_API_KEY=your_api_key_here
ETHEREUM_MAINNET_RPC=https://...

Current Status

✅ API endpoint corrected to v2 format
✅ Response parsing handles both v1 and v2 formats
✅ Gas price extraction working correctly
✅ Display formatting improved
✅ Conservative calculation using 2.5 gwei cap

Notes

Current gas prices (~0.1 gwei) are extremely low and not normal
System uses actual prices when below 2.5 gwei cap
For budgeting, consider normal market conditions (30-50 gwei)
