Chain basics
What token does Robinhood Chain use for gas?
Robinhood Chain uses ETH for gas on both mainnet and testnet. There is no separate native token.
Because it is an Arbitrum Orbit chain, gas has two components: L2 execution and the L1 calldata cost of posting the batch. Transaction receipts expose the second as gasUsedForL1, expressed in L2 units.
You can read the current L1 base-fee component through arb_getL1BaseFeeEstimate. Providers that treat Robinhood Chain as a generic EVM chain typically drop gasUsedForL1 from receipts, which makes accurate fee accounting impossible.
