Gas Fees for Trading on Robinhood Chain
Gas on Robinhood Chain (chain ID 4663) is paid in native ETH, priced per unit of computation. Every write — an approval, a swap, a bridge deposit — consumes a different amount of gas depending on the exact call, so the cost of trading a token is not a single number but a distribution that shifts with the router used and the pool the trade routes through.
The two questions worth answering before every trade are: do I hold enough ETH on chain 4663 to cover both the approval and the swap, and is the current base fee high enough that a small swap is going to look expensive relative to its output? Neither has a universal answer, but both are cheap to check.

What costs gas in a normal trade
A first-time swap pays for one approval transaction and one swap transaction. Repeat swaps of the same token from the same router skip the approval. Multi-hop routes cost more gas than single-hop routes because they touch more pool contracts inside the same swap.
Keeping enough ETH for both legs
Running your ETH balance to zero on the input side is a common failure: the swap consumes the ETH you would have used for gas on the next transaction. Keep a small reserve sized to at least a few typical trades so an approval or a fix-up transaction is not blocked by an empty balance.
Limitations
Any specific gas figure quoted here would go stale between blocks. Check the current base fee on Blockscout or the wallet's fee UI at the time of the trade; ranges published in guides are not a substitute for a live read.
Frequently asked questions
How much ETH should I keep for gas? Enough to cover several typical transactions at the current base fee, plus a buffer for any fix-up transactions like a re-approval or a manual revoke. The exact amount depends on live gas at trade time. Why did an approval cost less than the swap? An approval writes a single storage slot on the token contract. A swap runs the full pool logic — possibly across multiple hops — and typically touches more state, so it consumes more gas. Do failed transactions still cost gas? Yes. If a transaction reverts on chain 4663 you still pay for the computation up to the revert. That is one reason to size slippage and minimum output carefully rather than accept repeated retries.
