Robinhood Chain Gas Fees Explained: A Week of Data
A week ago Robinhood Chain gas was a rounding error. Now it is a line item, and people are asking why. We sampled the base fee every two hours for seven days, every fifteen minutes for the last twenty-four, and priced a dozen real actions at each level. The short version: gas rose about four times, most of that in three days, and it is still cents — except when it is not.
What gas costs right now
Robinhood Chain charges gas in ETH, and every action has a fixed gas budget that does not change with congestion — only the price per unit does. These are the measured gas figures for common actions, priced at the median base fee of the last 24 hours and at the worst spike in the same window.
| Action | Gas | At 0.405 gwei (24h median) | At 7.13 gwei (24h peak) |
|---|---|---|---|
| Send ETH | 21,000 | $0.02 | $0.37 |
| Approve a token | 46,643 | $0.05 | $0.82 |
| Send an ERC-20 | 51,480 | $0.05 | $0.91 |
| Wrap ETH to WETH | 58,459 | $0.06 | $1.03 |
| Sell on a Pons curve | 132,340 | $0.13 | $2.34 |
| Buy on a Pons curve | 156,494 | $0.16 | $2.76 |
| Deploy a standard ERC-20 | 564,365 | $0.57 | $9.96 |
| Launch a token on Pons | ~3,800,000 | $3.81 | $67 |
Buy, sell, deploy and launch are gasUsed from transactions we submitted on 29–30 August 2026; send, approve, ERC-20 transfer and wrap are eth_estimateGas on live contracts on 5 September.

Seven days of base fee
We read baseFeePerGas from 85 blocks spaced two hours apart. The daily medians tell the story; the daily maxima tell the other story.
Median of 12 two-hourly samples per day (3 on 29 Aug, 11 on 4–5 Sep). Denser 15-minute sampling on 4–5 Sep caught spikes the two-hourly grid missed: 7.13 gwei at 23:37 UTC on 4 Sep and 2.95 gwei at 20:21 UTC.
Three phases. On 29 August the base fee sat near 0.10 gwei, which looks like the network’s floor at the time. It roughly doubled on each of the next three days, reaching 0.49 gwei on 1 September. Since then it has held in a 0.37–0.49 band, with short spikes an order of magnitude higher. The lowest fee we saw in the last 24 hours was 0.377 gwei, on a block using only 0.5M gas — a block that empty should have let the fee decay further, which suggests the floor itself has moved up from 0.10.
Why gas fees rose
Robinhood Chain is built on the Arbitrum stack. Its base fee works like Ethereum’s: there is a target amount of gas per second, and when blocks consistently use more than the target the base fee climbs; when they use less, it decays toward a floor. So the question “why did gas rise” is really “what filled the blocks”. We compared the last 24 hours with the same window six days earlier.
| 29–30 Aug | 4–5 Sep | Change | |
|---|---|---|---|
| Median base fee | 0.138 gwei | 0.405 gwei | 2.9× |
| Gas used per block (avg) | 2.99M | 4.29M | 1.4× |
| Transactions per block (avg) | 13.0 | 16.0 | 1.2× |
| Transactions per day (est.) | 11.2M | 13.7M | 1.2× |
| Pons launches per hour | ~876 | ~1,370 | 1.6× |
48 and 96 sampled blocks respectively; per-day figures extrapolate the per-block average across the 858,278 blocks a day the chain produces at its measured 100.7 ms block time. Launch rate from TokenLaunched event counts on 30 August and 5 September.
Note what did not happen: transaction count rose only 20%. What rose was gas per transaction — blocks carry 43% more gas with 20% more transactions, because the mix shifted toward heavier calls. Launching a token costs about 3.8 million gas, 25 times a curve trade, and launches are up 60%. Even so, launches account for only about 3.4% of all gas used; the bulk of the growth is trading through routers, curves and Uniswap pools, which run 130,000 to 250,000 gas each.
Sustained demand above the target is exactly the condition under which an Arbitrum-style base fee ratchets up and stays up. The spikes to 3 and 7 gwei are bursts — a launch that draws a crowd of bots, a token graduating — and they decay within the hour.
What the chain is earning
On an Arbitrum-stack chain the base fee is not burned; it is paid to the chain’s operator. Multiplying each sampled block’s gas by its base fee gives a per-block fee, and the average across the day gives a revenue estimate.
Lower figure of each range weights blocks by the median fee, upper by the mean; the gap is the spikes. 96 and 48 sampled blocks respectively, extrapolated to 858,278 blocks a day. We report the range rather than a point because a handful of 7-gwei blocks move the mean materially. Base fee only; this is not a complete revenue figure.
Priority fees do nothing here
Wallets will still offer you a “priority fee” slider. On this chain it is decorative. The sequencer orders transactions first-come, first-served, and every receipt we checked settled at exactly the base fee regardless of the tip declared.
- In block 55,395,343, two of eight transactions declared a priority fee of up to 0.5 gwei. Every receipt in the block shows
effectiveGasPriceequal to the block’sbaseFeePerGasof 0.4093 gwei. - Our own 29 August curve buy declared a tip and settled at 0.114592 gwei — the base fee of its block, to the wei.
- The receipt’s
gasUsedForL1field is zero, and an ETH transfer estimates at exactly 21,000 gas: unlike Arbitrum One, there is no separate L1 data surcharge added to your gas. What you see is the whole fee.
Compared with other chains
Because there is no L1 surcharge, the gas price is the whole story, and it can be compared directly. At 20:03 UTC on 5 September we read the current gas price on five networks in the same minute.
eth_gasPrice on public RPCs. Ethereum L1 was unusually quiet; the L2 figures exclude their L1 data component, which Robinhood Chain does not charge, so per-transaction costs on Arbitrum, Base and Optimism are somewhat higher than the bars suggest.
Read plainly: at that moment Robinhood Chain charged about five times Ethereum mainnet’s price per unit of gas, twenty times Arbitrum One’s and roughly seventy times Base’s. A curve-sized trade of 156,494 gas cost $0.16 here against $0.03 on Ethereum. The comparison flatters L1 because L1 was empty, and it is still true. Our Robinhood Chain vs Base vs Solana comparison found Base 28× cheaper per unit a week earlier; the gap has since widened.
How much ETH to bring
Gas is paid in ETH and there is no faucet, so you bridge it in. Budget for the spike, not the median.
| Plan | At 0.405 gwei | At 7.13 gwei | Bring |
|---|---|---|---|
| 10 curve trades + 3 approvals | $1.59 | $28 | 0.015 ETH |
| Launch one token with a dev buy | $3.81 | $67 | 0.03 ETH |
| Deploy an ERC-20 and fund a V3 pool | $1.06 | $19 | 0.01 ETH |
Gas from the table above; pool funding assumed at roughly 400,000 gas for mint plus approvals. “Bring” is a comfortable reserve at the peak rate, excluding the ETH you intend to trade or deposit. Fees on top of gas — the 1% Pons curve fee, any creator tax, the swap interface’s cut — are covered in how to buy meme coins on Robinhood Chain.
Frequently asked questions
How much are Robinhood Chain gas fees?
At the 24-hour median base fee of 0.405 gwei on 5 September 2026: about $0.02 to send ETH, $0.05 to approve or transfer a token, $0.13–$0.16 to trade on a Pons curve, and about $3.81 in gas to launch a token. During the day’s peak of 7.13 gwei every figure was roughly 18 times higher.
Why are Robinhood Chain gas fees rising?
Because blocks are carrying 43% more gas than a week ago — heavier transactions, not many more of them — and the Arbitrum-style base fee climbs whenever demand stays above the target. Transaction count rose 20%; median base fee rose 2.9× to 0.405 gwei, with spikes to 7 gwei during bursts of launch and graduation activity.
Does Robinhood Chain use ETH for gas?
Yes. There is no separate gas token. The base fee is paid to the chain operator rather than burned, and there is no additional L1 data fee: an ETH transfer costs exactly 21,000 gas and the receipt’s gasUsedForL1 is zero.
Does a priority fee speed up my transaction on Robinhood Chain?
No. The sequencer is first-come, first-served, and every receipt we checked settled at the block’s base fee regardless of the tip declared. Set the priority fee to zero and the max fee comfortably above the current base fee.
Is Robinhood Chain cheaper than Base or Arbitrum?
Not per unit of gas on 5 September 2026: 0.41 gwei against 0.02 on Arbitrum One and 0.006 on Base, both of which then add an L1 data charge that Robinhood Chain does not. In absolute terms a trade still costs cents on all three; the difference matters mostly for launching contracts and for high-frequency bots.
