Gas mechanics
| Key | Value |
|---|---|
| Unit | USDC (18 decimals) |
| Pricing | EIP-1559–like base fee with exponentially weighted moving-average smoothing |
| Base fee (testnet) | ~160 Gwei minimum |
| Best practice | Surface gas fees in USDC and fetch the base fee dynamically when submitting transactions |
Policy overview
- The base fee is dynamically adjusted using a bounded, moving-average mechanism designed to stabilize around 160 Gwei under normal network load.
- Transactions submitted with a max fee below 160 Gwei may remain pending or fail to execute.
- To ensure timely inclusion, set
maxFeePerGas ≥ 160 Gwei.
Monitoring
You can view real-time gas metrics and recent averages using the Arc Gas Tracker.This configuration applies to the Arc Testnet and may evolve as network
parameters are tuned for mainnet launch.
