- The marketplace is OpenSea — the same Seaport order format as Ethereum, on an EVM chain whose native coin is ETH.
- No per-action fee. Unlike Solana, a bot on Robinhood Chain is charged only when an order fills — 0.1%.
- The buyer pays the ask; the seller pays the fees. The opposite of Tensor and Magic Eden on Solana.
- A "5% royalty" can cost 10%. Some collections publish two separate required creator fees — check before listing.
- Bids are WETH, listings are ETH — a Seaport rule: an offer cannot be made in a chain's native coin.
- Non-custodial. Transactions are signed in your own wallet, and cancelling an unfilled offer returns the WETH in full.
What Robinhood Chain is
Robinhood Chain is an EVM chain, so if you have traded on Ethereum everything will be familiar: wallets are 0x addresses, the native currency is ETH, and NFTs are ERC-721 or ERC-1155 rather than Solana's SPL and compressed formats.
What makes it interesting for trading is that it is new. The order books are thinner and the competition for a good listing is far lighter than on Ethereum — and most NFT automation simply does not support the chain yet, so a bot that does is at an unusual advantage.
The marketplace is OpenSea
There is no separate Robinhood NFT marketplace to learn. Trading happens on OpenSea, using the same Seaport order format as Ethereum — so a listing is a signed Seaport order and an offer is a signed Seaport offer, exactly as elsewhere.
Chadbot maintains that order book from OpenSea's websocket rather than polling an API on a timer, so a new listing, a re-price or a cancel shows up as it happens rather than on the next poll. The same feed drives the bots, so a sniper reacts to the event itself rather than to a refresh.
What a sale actually pays you
This is the part that surprises people, and it is worth getting right before you list rather than after your first sale.
On Tensor and Magic Eden the buyer is charged the marketplace fee and the royalty on top of the ask, so a seller receives the full asking price. OpenSea works the other way: the buyer pays exactly the ask, and the marketplace fee and every required creator fee are taken out of the seller's proceeds.
There is a second trap on top of that. A collection can publish more than one required creator fee, and OpenSea marks each one as either required or optional. A collection that looks like it charges a 5% royalty can in fact deduct two separate 5% fees plus OpenSea's own 1% — 11% in total, none of it avoidable.
The bots that run here
All three bot types work on Robinhood Chain, and none of them charges you for the work of staying competitive:
- Bidding bots keep a collection offer live and competitive, re-pricing as the book moves — see how auto-bidding works. Offers are denominated in WETH.
- Listing bots list and re-price for you, following the floor down but never below a minimum you set, so a bot cannot sell into a collapse at any price.
- The sniper auto-buys the instant a listing lands at or under your maximum — by floor, by rarity rank or by specific traits — with budget, buy-limit and lifetime guardrails, and a paper mode for testing a rule without spending anything.
Why running a bot here is free until it works
On Solana, Chadbot charges a small per-transaction fee for each action a bot takes. On Robinhood Chain there is no per-action fee at all. A bidding or listing bot costs 0.1% when an order actually fills, and nothing while it waits, re-prices or cancels — so a bot that sits on the book for a week without filling has cost you only network gas.
The sniper is charged only on a completed buy, at 10% of the buy price, falling to 8%, 6% or 5% for Chadbots NFT holders.
Why bids are WETH and listings are ETH
A Seaport offer cannot be denominated in a chain's native coin, so bids are made in wrapped ETH (WETH) while listings are priced in ETH. That is a property of the order format, not a Chadbot decision, and it is the same on Ethereum.
Chadbot wraps and unwraps as needed and shows each amount in the currency it is actually denominated in. It never converts one chain's total into another's — an ETH figure and a SOL figure are never added together.
FAQ
What is Robinhood Chain, and where do its NFTs trade?
Robinhood Chain is an EVM chain, so it behaves like Ethereum rather than Solana: wallets are 0x addresses and the native currency is ETH. Its NFT marketplace is OpenSea, running the same Seaport order format as Ethereum. Chadbot reads that order book from OpenSea's websocket rather than polling it, so listings and bids appear as they happen.
What does Chadbot charge to run bots on Robinhood Chain?
Nothing per action. On Solana the bots charge a small per-transaction fee for each bid edit or reprice; on Robinhood Chain and Ethereum there is no per-action fee at all. A bidding or listing bot costs 0.1% when an order actually fills, and nothing while it waits, reprices or cancels. The sniper is charged only on a completed buy, at 10% of the buy price, falling to 8%, 6% or 5% for Chadbots NFT holders.
Why did I receive less than I expected when my NFT sold?
Because on OpenSea the fees come out of the seller's side, and a collection can require more of them than the headline royalty suggests. The buyer pays exactly the asking price; the marketplace fee and every required creator fee are deducted from your proceeds. Some collections publish two separate creator fees, so a listing that looks like it carries a 5% royalty can deduct 10%, plus OpenSea's own 1%. Chadbot reads each collection's required fees directly from OpenSea and shows whether the royalty is optional or mandatory before you list.
Why are my bids in WETH when listings are in ETH?
It is a Seaport rule, not a Chadbot choice. An offer cannot be denominated in a chain's native coin, so bids are made in wrapped ETH while listings are priced in ETH. Chadbot handles the wrapping and shows each amount in the currency it is actually denominated in, rather than silently converting one into the other.
Can the sniper run on Robinhood Chain?
Yes. It watches the live OpenSea feed and buys the instant a listing lands at or below your maximum price, and it can target a collection floor, a rarity rank or specific traits. The same budget, buy-limit and lifetime guardrails apply as on Solana, and paper mode lets you test a rule without spending anything.
Does Chadbot hold my funds on Robinhood Chain?
No. Chadbot is non-custodial on every chain it supports. Transactions are signed in your own wallet, and an unfilled offer can be cancelled to return the WETH to you in full.
