Three tiers straight from the chain gas oracle, converted to dollars at the current ETH price. The arithmetic is printed under every number so you can check it.
21,000 gas × 0.08 gwei = 0.00000168 ETH × $1,940.56/ETH
21,000 gas × 0.17 gwei = 0.00000357 ETH × $1,940.56/ETH
21,000 gas × 0.67 gwei = 0.00001407 ETH × $1,940.56/ETH
Tiers and ETH price from https://robinhoodchain.blockscout.com/api/v2/stats. gwei is 1e-9 ETH, so cost in ETH is gas × gwei ÷ 1,000,000,000, then multiplied by the ETH price.
At the average tier a plain ETH transfer costs $0.006928. Fees on this chain are a fraction of a cent, so gas is rarely the reason a transaction is worth waiting on.
| Action | Gas units | Cost in ETH | Cost in USD | Basis |
|---|---|---|---|---|
| ETH transfer | 21,000 | 0.00000357 | $0.006928 | Fixed by the EVM. Intrinsic cost of a plain value transfer. |
| ERC-20 transfer | 65,000 | 0.00001105 | $0.021443 | Typical. Higher when the recipient balance slot is written for the first time. |
| Token approval | 46,000 | 0.00000782 | $0.015175 | Typical. One allowance storage write. |
| Uniswap-style swap | 150,000 | 0.0000255 | $0.049484 | Typical. Route length and pool type move this a lot. |
These gas amounts are typical estimates, not measurements taken on this chain. They are the conventional figures used across EVM tooling. Only the 21,000 unit ETH transfer is fixed by the protocol. Costs are computed at the average tier (0.17 gwei). Your actual transaction can differ.
An hourly gas heatmap and a gas guzzler leaderboard are not on this page because they need a block by block index of our own. The upstream API exposes a current reading, not history, so building those from it would mean guessing. We would rather show nothing than a made up curve.
