Insufficient Gas on Robinhood Chain
Gas on Robinhood Chain (chain ID 4663) is paid in ETH, so an 'insufficient gas' error almost always means the sending address does not hold enough native ETH to cover the wallet's estimated transaction cost. It is not a chain-side error — the wallet is refusing to broadcast a transaction it knows will fail underfunded.
This flow shows how to confirm the balance on Blockscout, how to read the wallet's estimate honestly (including buffer for gas spikes), and safe ways to top up. Never sign a transaction just because the wallet lets you override the warning.

Likely causes
Ordered by frequency: native ETH balance on chain 4663 is below the estimated cost; the estimate is inflated by an unrelated failing simulation (e.g. missing approval); the wallet is reading balance from a stale RPC; the account you think holds ETH is not the account the dapp is calling from.
Safe checks
1. Open the sending address on robinhoodchain.blockscout.com and confirm the native ETH balance directly from chain state. 2. Compare that number to the wallet's shown estimate, including any buffer the wallet adds. 3. Confirm the dapp is calling from the same address you just checked — a common trap is having two accounts in one wallet and funding the wrong one.
Resolution steps
If balance is genuinely low, bridge in a modest amount of ETH via the official Robinhood Chain bridge and confirm it arrived on chain 4663 before retrying. If balance is fine but estimate is high, the underlying transaction is likely failing for a different reason (approval, revert) — fix that root cause instead of raising the gas ceiling.
Escalation limits
Never raise gas limit repeatedly to force a transaction through — an underfunded transaction cannot succeed by paying more, and a failing transaction that consumes gas still consumes gas even when it reverts. If two attempts fail, stop and re-diagnose rather than escalating spend.
Prevention
Keep a small ETH float on chain 4663 above your typical transaction cost so a modest gas spike does not block trades. Bridge in round amounts to avoid pinning the balance at exactly the estimate.
Frequently asked questions
Is gas on Robinhood Chain paid in a special token? No. Robinhood's own docs specify that gas on chain 4663 is paid in native ETH. There is no separate gas token; if you see one asked for, treat it as a red flag. Why does the wallet estimate change between clicks? Because it re-simulates the transaction against current chain state. If pool state, allowance, or nonce changed, the simulation cost can move. That is normal and not evidence of manipulation. Can I just increase the gas limit to fix this? No. Gas limit is a ceiling, not a top-up. If your balance is below what the transaction would spend at the base fee, no limit change fixes it. Bridge in more ETH instead.
