Robinhood Chain vs Arbitrum One: same technology, different chains
Robinhood Chain uses Arbitrum's technology, so people often assume it is part of Arbitrum One, or that a token on one is the same as a token on the other. It is not. They are separate networks with separate balances.
Side by side
| Arbitrum One | Robinhood Chain | |
|---|---|---|
| Built with | Arbitrum Nitro | Arbitrum Orbit / Nitro |
| Settles to | Ethereum | Ethereum |
| Gas token | ETH | ETH |
| Chain ID | 42161 | 4663 |
| Sequencer | Run by Offchain Labs | Run by Robinhood, first come first served |
| Governance | The Arbitrum DAO, with the ARB token | Robinhood with an eight-seat security council (two Robinhood seats; Offchain Labs, Chainlink Labs, Paxos, BitGo, Fireblocks and Talos one each) |
| Native token | ARB (governance) | None |
| What trades there | A broad DeFi ecosystem | Stock Tokens, a Uniswap deployment, launchpads like Pons and Pools.trade, and memecoins |
| Explorer | Arbiscan and others | robinhoodchain.blockscout.com |
What "built on Arbitrum" means
Orbit is Arbitrum's kit for launching your own chain. Robinhood used it the way a company might use an open-source database: same engine, separate deployment. Robinhood Chain posts its data to Ethereum directly, not through Arbitrum One, and withdrawals use the same roughly week-long challenge period. See Robinhood Chain bridge.
Why the difference matters to a trader
- Balances do not carry over. ETH or tokens on Arbitrum One are not on Robinhood Chain until you bridge them.
- Same ticker, different contract. A token on Arbitrum One presented as a Robinhood Chain coin is a common trick. Check the chain ID and the official explorer.
- Different control. Arbitrum One's rules are set by its DAO. Robinhood Chain's sequencer and upgrades sit with Robinhood and its council; see is Robinhood Chain decentralized.
Holder checks are the same
Whichever chain a coin is on, the questions do not change: who holds it, are they linked, what did the dev do. Whodl reads Robinhood Chain coins through its explorer; paste a contract into the web chat. Compare Robinhood Chain with other memecoin chains in Robinhood Chain vs Base and Robinhood Chain vs Solana.
