NFTs on Robinhood Chain, explained
New to Robinhood Chain, or just curious what all the Oozlings fuss is about? Here is what the network is, where its NFTs trade, and how to make sure you are looking at the real thing.
What is Robinhood Chain?
Robinhood Chain is an Ethereum Layer 2 network built with Arbitrum technology (Arbitrum Orbit). Its public mainnet went live on July 1, 2026. Like other Layer 2s, it batches transactions and settles them back to Ethereum, which keeps fees low and confirmations quick.
Because it speaks the same language as Ethereum (the EVM), everything you know about Ethereum NFTs carries over. Collections are ERC-721 or ERC-1155 contracts, you pay gas in ETH, and wallets like MetaMask or Rabby work once the network is added.
The one thing to remember: Robinhood Chain is its own network. An NFT on Robinhood Chain does not show up on Ethereum mainnet, and ETH on mainnet has to be bridged before you can use it here.

Where Robinhood Chain NFTs trade
- OpenSea. OpenSea added Robinhood Chain on July 11, 2026. You can browse it with the Robinhood Chain network filter. OpenSea's Seaport trading contract is deployed on the chain.
- Element. Element also lists Robinhood Chain collections. Oozlings shows up there under the same contract address: element.market/collections/oozlings.
A marketplace is just a storefront. The NFT itself lives in the contract on Robinhood Chain, so the same token can appear on more than one marketplace. What matters is that the contract address and network match the ones the project publishes.

How to check an NFT contract
- Get the address from the source. Use the project's own website or official X account, not a reply, DM or ad.
- Open it on the explorer. Paste the address into Blockscout. You should see a token contract with the expected name and symbol, and a history of real transfers.
- Match the marketplace. On OpenSea, open the collection's details and check that the network says Robinhood Chain and the contract address is identical, character for character.
- Watch for lookalikes. Copycat collections reuse names and art. A different address means a different collection, even if everything else looks the same.
- Be careful with signatures. Buying an NFT is one transaction. If a site you didn't open yourself asks you to approve all your tokens, close it.
Example: checking Oozlings
Oozlings are weird little aliens from The Ooze Pits, an NFT collection built on Robinhood Chain. Here's what the checks above look like for us:
- Contract address: 0x674bF3477B4021C5E1aA27d7100DA6C8eEe0AC03
- On the explorer: Oozlings on Blockscout. The contract reports its name and symbol as
Oozlings. - On OpenSea: opensea.io/collection/oozlings, network Robinhood Chain, same address.
- Every token has a holder page at oozlings.com/oozling/<id> that reads the current owner and days held straight from the chain. No wallet connection needed.
Got one? Make a profile picture or X banner with the Pit Kit, look up any Oozling in the OozDex, or read the lore.

FAQ
What is Robinhood Chain?
Robinhood Chain is an Ethereum Layer 2 network built with Arbitrum technology. Its public mainnet went live on July 1, 2026. It runs the same kind of smart contracts as Ethereum, so NFTs there work just like NFTs on Ethereum, but transactions are faster and gas fees are usually much lower.
What is the chain ID of Robinhood Chain?
The mainnet chain ID is 4663 (0x1237 in hex). The testnet uses 46630. If your wallet shows a different chain ID, you are on the wrong network.
What do I pay gas with on Robinhood Chain?
ETH. You need a little ETH on Robinhood Chain itself to buy, sell or move an NFT. ETH sitting on Ethereum mainnet has to be bridged over first.
Where can I buy NFTs on Robinhood Chain?
OpenSea has supported Robinhood Chain since July 11, 2026, and you can filter OpenSea by the Robinhood Chain network. Element also lists Robinhood Chain collections. Always open a collection from the link on the project's own website or X account.
Can I use MetaMask with Robinhood Chain?
Yes. Any EVM wallet such as MetaMask or Rabby works once you add the network with chain ID 4663 and the official RPC URL. Our step-by-step guide walks through it.
How do I know an NFT collection is the real one?
Compare the contract address. Get it from the project's official site or X account, then check that the marketplace listing and the block explorer show the exact same address on Robinhood Chain. Names and pictures are easy to copy. Contract addresses are not.
