How to Add Robinhood Chain to MetaMask: The Wrong Chain ID Trap That Looks Like Lost ETH
- Add Robinhood Chain manually with chain ID 4663. The RPC URL alone won’t save you.
- Gas is paid in ETH on the L2; fees are a fraction of a cent, but you still need bridged ETH on Robinhood Chain.
- After adding, paste your address into Blockscout before assuming funds are missing — MetaMask doesn’t switch networks automatically.
- For memecoins on BigPump, pre-graduation trades carry a 1% pool fee only; creator tax and holder dividends start after graduation.
Your ETH isn’t lost. It’s sitting on Ethereum mainnet while MetaMask shows you the wrong network. I watched a friend paste the Robinhood Chain RPC into MetaMask three times, then declare the network broken. It wasn’t broken — he just never switched. This is the exact setup for Robinhood Chain, an Ethereum Layer‑2 built on Arbitrum Orbit technology where gas is paid in ETH and the chain ID is the number that actually matters: 4663.
Chain ID 4663 is the only number you should trust. A custom network name and a matching RPC URL mean nothing if the chain ID is wrong.
Add Robinhood Chain to MetaMask with these exact settings
MetaMask doesn’t ship with Robinhood Chain in its default network list. You add it manually. Open MetaMask → network dropdown → Add network → Add a network manually. Then enter these values, not a screenshot from a random group chat:
| Field | Value |
|---|---|
| Network name | Robinhood Chain |
| RPC URL | https://rpc.mainnet.chain.robinhood.com |
| Chain ID | 4663 |
| Currency symbol | ETH |
| Block explorer URL | https://robinhoodchain.blockscout.com |
Network name is cosmetic — I use “Robinhood Chain” so I don’t confuse it with Ethereum mainnet. The RPC URL and chain ID must be exact. There is no separate gas token here: gas is paid in ETH, just on an L2, and network fees are a fraction of a cent.
The wrong-chain-ID trap that makes you think your ETH is lost
Here’s where people get rugged by their own wallet. They add the network, glance at MetaMask, and see zero. Their stomach drops. They assume the bridge lost their funds. In most cases the ETH is still on Ethereum mainnet, or they simply stayed connected to Ethereum mainnet after adding the new network.
Do this before you panic: copy your address, paste it into Blockscout, and see what the chain itself says. If the explorer shows your ETH on Robinhood Chain and MetaMask shows zero, you’re likely on the wrong network selection. Switch manually in MetaMask to the network you just added. If the explorer shows zero, your funds haven’t arrived yet or are still on mainnet — check how to bridge ETH to Robinhood Chain.
I’ve seen people add “Robinhood Chain” with a random chain ID from a bad tutorial and then wonder why transactions fail. The only way to be sure is the network settings dialog: the chain ID must read 4663. Not 46, not 466, not “Robinhood Mainnet”. That one number is the difference between being on the real L2 and staring at a testnet fork.
Once MetaMask is on Robinhood Chain, here’s how to actually use it
Adding the network is only step one. You still need ETH on Robinhood Chain for gas. Yes, ETH. The chain doesn’t have a separate gas token, which is why bridging matters. If you haven’t bridged yet, your wallet balance on Robinhood Chain will be empty even if Ethereum mainnet has plenty of ETH. Use the official bridge from Ethereum mainnet, and remember fees are tiny once you’re on the L2.
If you’re here because you want to trade or launch memecoins, the next stop is checking what’s live on the chain. I use BigPump’s token board to see new launches and graduated tokens on Robinhood Chain. BigPump is a launchpad where tokens start on a bonding curve, then graduate to Uniswap V2 with liquidity locked. Before you buy, know this: pre-graduation trades on the bonding curve only have a 1% pool fee; the creator tax and holder dividends only kick in after graduation on Uniswap. That changes the math on when you enter. If you want the full picture before you ape, read this guide on Robinhood Chain memecoins.
Robinhood Chain has Uniswap V2, V3 and V4 deployed, plus other DEXes, so BigPump isn’t your only option. After you add the network, spend five minutes checking actual chain data instead of chasing the same “wen balance” panic.
FAQ
Why does MetaMask still say “Wrong network” after I added Robinhood Chain?
Adding a network doesn’t always switch to it automatically. Open the network dropdown in MetaMask and click Robinhood Chain. Also check that the chain ID in settings is 4663. If MetaMask says that chain ID is already used by another network, review your added networks and remove the duplicate.
Do I need a different gas token for Robinhood Chain?
No. Gas is paid in ETH, the same ETH you know from Ethereum mainnet. You just need ETH on Robinhood Chain itself. Bridged ETH from mainnet works fine, and transaction fees are a fraction of a cent.
Can I add Robinhood Chain automatically from a website instead of typing the RPC?
Yes. Many dapps offer an “Add to MetaMask” button that fills in the network parameters for you. That’s fine as long as you verify the chain ID is 4663 before confirming. Never enter your seed phrase or private keys anywhere. If a site asks for that after adding a network, close the tab. If tax behavior still confuses you, the BigPump FAQ clears up a lot.
If you only do one thing after reading this, check the chain ID.
- Open MetaMask network settings.
- Confirm the chain ID is 4663.
- Paste your address into Blockscout to verify the actual balance.
- Bridge ETH only through the official bridge — gas is paid in ETH on Robinhood Chain.
