There are three ways into Robinhood Chain: a withdrawal from an exchange that lists the network, the canonical bridge from Ethereum through the Arbitrum portal, and partner bridges; the canonical way back to Ethereum takes about seven days.

Route one: withdraw from an exchange into Robinhood Chain
Some exchanges list Robinhood Chain in the network selector of their withdrawal form, under the name Robinhood or Robinhood Chain. A row named Ethereum is a different network. The destination is an EVM address: Robinhood Chain works with EVM wallets, MetaMask included.
Withdrawal fees to Robinhood Chain
| Exchange | Network on the exchange | Fee | Minimum | Withdrawals | Withdraw |
|---|---|---|---|---|---|
| OKX | ROBINHOODCHAIN | 0 ETH | 0 ETH | Closed | Withdraw |
| OKX | ROBINHOOD CHAIN | 0.0000016 ETH | 0.0001 ETH | Open | Withdraw |
| Bitget | ROBINHOOD | 0.000004 ETH | 0.0037553 ETH | Closed | Withdraw |
| KuCoin | ROBINHOOD | 0.0002 ETH | 0.0004 ETH | Open | Withdraw |
| BingX | ROBINHOOD | 0.0006 ETH | 0.002014 ETH | Open | Withdraw |
| Kraken | ROBINHOOD CHAIN | 0.0007 ETH | 0.0021 ETH | Open | Withdraw |
| Gate.io | ROBINHOOD | 0.05 USDG | 0.009999 USDG | Open | Withdraw |
| KuCoin | ROBINHOOD | 0.5 USDG | 1 USDG | Open | Withdraw |
| BingX | ROBINHOOD | 1.5 USDG | 5 USDG | Open | Withdraw |
| Kraken | ROBINHOOD CHAIN | 1.5 USDG | 5 USDG | Open | Withdraw |

Route two: the canonical bridge from Ethereum
If the coins already sit in your own wallet on Ethereum, the documentation points to one tool: "To bridge ETH or ERC-20 tokens from Ethereum to Robinhood Chain, use the Arbitrum canonical bridge". The link in the documentation leads to the Arbitrum portal with Ethereum as the source and Robinhood Chain as the destination. Take that link from the bridging page itself.
Robinhood calls it "the trustless default for moving funds between Ethereum and Robinhood Chain". It "requires no third-party validators — security is inherited directly from Ethereum". Deposits "typically confirm within 10 minutes".
A deposit runs on Arbitrum's retryable ticket system. If its Robinhood Chain leg fails, "for example, due to insufficient gas", the funds are not lost: the deposit "can be manually redeemed from the bridge interface within 7 days".
A token changes its address on the way. The documentation states that "a bridged ERC-20's contract address on Robinhood Chain differs from its address on Ethereum". The address on Robinhood Chain is resolved by calling calculateL2TokenAddress on the L2 Gateway Router, whose own address is listed on the protocol contracts page. The official addresses of WETH, USDG and Stock Tokens are on the token contracts page.
Route three: third-party bridges
Beside the canonical bridge, the bridging page lists "several cross-chain routes from partners" that "offer faster transfers and broader network coverage". Their type and speed, as the page gives them:
- Stargate, on LayerZero OFT: minutes, varying with the finality of the source chain. The page names it for moving WBTC, USDG and other OFT tokens.
- Transporter, on Chainlink CCIP: minutes, varying with source-chain finality. Token transfers and cross-chain messages.
- Relay: an intents-based bridge, seconds. It can also trigger an action on the destination chain in the same step.
- Across: an intents-based bridge, seconds.
- LiFi and 0x: cross-chain swap aggregators, seconds to minutes. A swap and a bridge in one step.
These are separate services, each on its own site.
Getting back to Ethereum: why the canonical route takes seven days
A canonical withdrawal is, in the documentation's words, "a three-step process":
- Start the withdrawal on Robinhood Chain.
- Wait out the seven-day challenge period, "a standard requirement of Arbitrum's fraud proof system".
- Claim the funds with a transaction on Ethereum. The documentation calls this step required, and it "incurs L1 gas costs": the wallet needs ETH on Ethereum as well.
The seven days are not the time it takes a transaction to become final. The transaction finality page lists three stages: a soft confirmation from the sequencer in under a second, the batch posted to Ethereum within minutes, and Ethereum finality about 13 minutes after posting. The same page says that "Finality is distinct from the withdrawal delay": the challenge period applies to moving assets back to Ethereum through the canonical bridge.
The seven-day period is stated for the canonical bridge. The partner routes carry the speeds listed in the previous section.
Back to an exchange
Coins return to an exchange as a deposit in the Robinhood Chain network: to a deposit address for the same asset and the same network, on an exchange that accepts that asset from Robinhood Chain. The exchanges that accept deposits from this network are listed on the Robinhood Chain hub. When the exchange you need does not accept the asset from Robinhood Chain, the route out is a bridge to Ethereum or to another network that exchange accepts.
Before you send
- The network, not only the asset. In an exchange form it reads Robinhood or Robinhood Chain; in a wallet, the mainnet chain ID is
4663. - The address. An EVM address copied from your own wallet.
- The minimum. The table above shows it for each exchange next to the fee.
- ETH for gas on the destination side. Gas on Robinhood Chain is paid in ETH, and a canonical withdrawal is claimed on Ethereum with L1 gas.
- Bridge links from the documentation. The bridging page links to the canonical bridge and to every partner route.
- Check the token contract, not the ticker. How to do that on the explorer: checking a token contract on Robinhood Chain.
Gas on the chain is ETH, and Robinhood has announced no network token: does Robinhood Chain have a token. Everything about the network in one place — chain ID, explorer, live routes — is on the Robinhood Chain hub.
