NFT liquidity on Robinhood Chain: the Anvil AMM and the Interns desks

Robinhood Chain has two ways to trade NFTs without waiting for a counterparty. The Anvil NFT AMM prices a whole collection against a vault, the same way a token AMM prices a pool, so you can buy or sell a StonkBroker in one transaction at a known price. The Interns desks are the peer to peer version: anyone opens a desk, stakes tokens or NFTs into it, and earns the fee on every fill. Both are live on stonkbrokers.io/marketplace.

The Anvil NFT AMM

The Anvil AMM (anvil.clutch.market) is the NFT liquidity protocol behind the StonkBrokers marketplace. A collection deposits NFTs into a vault paired with a collection token; buys pull an NFT out at the curve price and sells push one in. The StonkBrokers market uses $STONKBROKER as its collection token, so every broker trade is also $STONKBROKER volume.

The flat ETH fee splits half to the treasury and half to Clock In, which is one of the reasons every trade on the floor grows the stock token distributions to holders. The Trade tab also carries a trait filter and a broker number lookup that shows whether a broker in the vault still has its two interns inside.

Deploy an Anvil market for your collection

The Anvil factory is permissionless. Any team can create a market for an ERC-721 collection on Robinhood Chain for a flat 1 ETH creation fee, seed it with NFTs, set the swap and snipe fees, and turn on soft staking and loans. Markets on Ethereum, Base, and ApeChain run on the same factory generation. Reward streams let a team airdrop any ERC-20 to activated holders as a 30 day drip. Start at the create market wizard. Third party teams licensed under the protocol's BUSL terms, such as Chain Mancers, Yardkeepers, Card Wall, and the Nightshades factions, already run their collections this way.

The Interns desks

The Interns desks are run by the Stonk Interns and open to every collection. Three desk types:

• Stake tokens, desk buys NFTs · you post bids along a price ladder and hold what the desk buys until you withdraw.
• Stake NFTs, desk sells NFTs · you list along an ask ladder and collect the quote token as they fill.
• Stake both, Anvil two way · the desk relists what it buys at spot times your delta, so it market makes continuously.

Every fill pays a 9.99% fee in kind, 66% to the desk depositor, 25% to the intern Clock In engine, and 9% to the protocol. Desks quote in ETH, $STONKBROKER, USDG, and Robinhood stock tokens on Robinhood Chain, in ETH, WBTC, USDC, USDT, APE, and XAUt on Ethereum, and in APE, WAPE, ApeUSD, and USDC.e on ApeChain. The floor is a gallery sorted by USD ask with a cart that routes across desks for the best price, and Bids does the same for sellers.

OpenSea and royalties

Both collections also trade on OpenSea through Seaport, the only order book marketplace on Robinhood Chain. StonkBrokers carries a 6.66% royalty and Stonk Interns 9.99%, enforced by ERC-721C transfer validators, with the proceeds flowing into Clock In. Sales are tweeted live by the StonkBrokers sales bot.
