Robinhood Chain testnet addresses from the hackathon demo. Do not use on mainnet (chain ID 4663).

StonkBrokers launched as a fixed set of 4,444 items in mid-2026 on Robinhood Chain and is one of the first collections built on the ERC-6551 token-bound wallet standard. Every broker owns a real on-chain wallet that is seeded with tokenized stock at mint and earns stock-token distributions from Anvil AMM trading fees. Created by Clutch Markets, the brokers carry collective ownership of the Stonk Exchange, including the Stonk Launcher token launchpad and the vDEX.

StonkBrokers is a unified collection of 4,444 unique pixel art stock brokers, each with an ERC-6551 Token-Bound Account. The free mint is closed — the collection is fully minted out. Acquire brokers on the Anvil NFT AMM after buying $STONKBROKER on OpenSea.

Whitelist slots were historically earned by burning Pup Cup (Ethereum) or Clutch Puppies (ApeChain) NFTs before Thursday, July 16 · 11:59 PM EST. That path is closed; ApeChain is not a product surface on this site.

Collection Details

How to get a broker

1. 1.Buy $STONKBROKER on OpenSea via the Get tab.
2. 2.On Trade, swap 666,666 $STONKBROKER + ETH fee for the next vault broker, or snipe an exact # from inventory (ETH trade fee applies).
3. 3.Each broker has a token bound wallet that holds stock drops and travels with the NFT.
4. 4.Activate on the Activate tab to earn tier weighted distributions when someone Clocks In.

Home for broker trading, activation, distributions, and loans. Flat AMM price is 666,666 $STONKBROKER + ETH fee plus a native ETH trade fee (10% swap / 15% snipe), split 70% StockBooster / 30% protocol.

Features

• ▸Get tab — buy $STONKBROKER on OpenSea.
• ▸Trade — swap $STONKBROKER for the next vault broker, or snipe a specific #.
• ▸My Brokers — token bound wallet balances and share art.
• ▸Activate — stake a broker on the distribution payroll (tier weighted).
• ▸Distributions — Clock In when the ETH pot is full to swap into stock and airdrop.
• ▸Loans — borrow full principal against a broker; pay ETH fee upfront.

Open /marketplace. See Contract Addresses for the AMM vault and related contracts.

Trading fees in native ETH fund the StockBooster (70% of every Anvil market trade fee). Only activated brokers receive stock airdrops, weighted by tier.

Broker Activation

Activation fees are paid in $STONKBROKER (50% burned, 50% protocol by default). Activation clears on true ownership transfer.

Clock In

Clock In is the StonkBrokers motto: the distribution flow is 100% onchain and run by the community itself. Every activated broker directs its own share — pick up to 3 tokens from the menu on the Activate desk (weights of your choosing, 100% into one is fine); brokers with no election on file receive the program default (ETH). When the accrued ETH bar is full, any wallet can hit Clock In and pay gas: the engine tallies elections, swaps the pot into each demanded token in one pass, and credits every broker pro rata by tier weight. Credits are pushed into broker wallets automatically — or collect yours instantly with the Deliver button. No bot required; resume open rounds with the same button.

Overtime (retired)

Overtime was the royalty-funded second shift on the Distributions desk. It has been merged into Clock In v2 — royalties now feed the same elected-stock engine as trade fees. Historical Overtime rows keep their Bloomberg-orange styling in airdrop history, and past Overtime tickers keep resolving in wallets.

Robinhood Token multipliers (corp actions)

Robinhood Stock Tokens implement ERC-8056. Dividends and splits update an onchain uiMultiplier() (shares per token) instead of rebasing balances — so raw token amounts stay put while each token can represent more than one share. Chainlink USD feeds already quote the total-return token price (share price × multiplier); the UI shows the live × factor on Distributions and My Brokers. This is not the same as Clock In / Overtime protocol drops, which are AMM and royalty fee airdrops — not corporate dividends. See Robinhood Chain docs.

Borrow the full 666,666 $STONKBROKER + ETH fee principal against a broker as collateral. The fee is paid in ETH upfront at 15% APR on the market ETH notional for the loan duration (minimum term floors the fee so borrowing is never cheaper than an AMM exit). Excess msg.value is refunded. Fees split 70% StockBooster / 30% protocol. Repay returns exactly the principal in $STONKBROKER; overdue loans owe an additional ETH late fee at the same rate.

UI: /marketplace?tab=loans. Contract: Loan Vault in addresses.

Lock LP on Robinhood Chain to prove liquidity commitments while keeping swap-fee income. Two lockers: the V3 locker escrows an existing Uniswap V3 LP position NFT; the V4 locker mints and custodies a native-ETH Uniswap V4 position directly in the canonical PoolManager (V4 position NFTs can't be escrowed as-is — the UI detects them in your wallet and prefills a matching deposit instead). Every lock issues a transferable ownership NFT; whoever holds it collects the position's swap fees and, once the window opens, withdraws the liquidity.

Fee modes (chosen at lock time, immutable)

A legacy third mode (1% on withdraw) still functions for locks that chose it but is no longer offered for new locks.

Lock styles & unlock windows

Each lock sets a start and finish timestamp: nothing is withdrawable before start, liquidity vests linearly between the two, and after finish the position is fully withdrawable and releasable. The UI offers three styles built on that window:

Lock cards badge every deposit as HARD LOCK, LINEAR VESTING, or PERMANENT so the semantics are readable at a glance. The UI stamps windows a few minutes ahead at submit so transactions can't revert with a past start time; this only ever delays a window, never shortens it.

Where protocol fees go

All locker protocol fees route to the Safety Deposit Clock In contract — an ownerless, pull-based router with a 90% community / 10% protocol split. ETH and WETH flow to the Stock Booster (funding Clock In stock drops); other tokens open claim rounds that activated brokers pull into their token-bound wallets, each broker claiming its own tier-weighted share.

Safety properties

• ▸No admin key can seize, withdraw, or release locked liquidity — the owner can only rotate the fee recipient for future fees.
• ▸Locked principal is mathematically unwithdrawable before the unlock window opens; permanent locks can never be withdrawn by anyone.
• ▸Only the current holder of the lock's ownership NFT can collect swap fees, withdraw vested liquidity, or release the position.
• ▸Lock windows are fixed inside the signed transaction — no third party can shorten them after the fact.

Collectively owned token launchpad on Robinhood Chain. Supports fixed price, bonding curve, and highly customizable launch configs — then finalize into Uniswap V3 with automatic LP, fee splitting, and a staking vault for every launched token. Pair against ETH, $STONKBROKER (featured), or tokenized stocks. Launch fee is 0.00042069 ETH; graduation threshold defaults to 4.0 units of the pair asset.

Owned and curated by StonkBrokers and $STONKBROKER holders. Launcher fees help fund stock drops; launched tokens can list on Stonk Exchange (vDEX).

Lifecycle

Opening Bell Buybacks — VRNG-triggered market buys

Every bonding-curve trade pays the launcher fee — and a fixed slice of every fee streams into the Buyback Bar, an on-chain pot that charges as the floor trades. When the bar is full, the miner-backed VRNG (the same certified-print entropy that runs Broker Box) draws two things nobody — not traders, not miners, not the team — can predict or forge: when the bell becomes ring-able, and which live bonding-curve token gets bought.

On every other launchpad the fee is pure exit — value leaves the floor and never comes back. Here the house edge is pointed back at the tokens themselves: fees recycle into random, unfrontrunnable buybacks, so expected value flows back to the people actually trading. It is designed to be the highest-RTP meme-coin trading floor crypto has ever seen — the entropy path is byte-identical to Broker Box's audited draw (a pure function of a future certified print), so buyback timing can't be sniped, ground, or selectively aborted by anyone, including us.

UI: /launcher.

Live on Robinhood Chain mainnet. The floor is the World Wide Stonk Exchange: two counters share one deed collection (First Edition Original Mint). The Certificate Counter sells any listed stock sealed in a bearer deed at exactly 1×. Degen Mode (Play the Box) rolls your multiplier on miner-backed VRNG from 0.70× to the 50× bell and pays out real Robinhood stock tokens the same way. Design RTP is 90.00%. UI: /broker-box.

Machines are ownerless: no pause switch, no upgrade path, no key to player funds. The stocker (treasury on official machines, creator on community launches) can only reclaim idle seed capital and spare bankroll — never reserved prizes, player-owed ETH, or parked protocol accrual. Stock-token play and counter mints are unavailable in the United States; settles, rescues, redeems, and cash-outs still work.

Two counters

Live floor (mainnet machines)

Nine production machines share one certificate collection. Every machine passed a live router-route probe at launch. The counter shelf can also list route-live stocks that do not have a machine (e.g. feed-less tapes sold OTC only).

Tickets, inventory & ladder

Contract tiers run $10 / $50 / $100 / $250 / $500 / $1,000. Mainnet sells up through $100 (hard entropy-grind security ceiling: max outcome $5,000 at 50×). A tier opens on a machine when free stock can reserve one worst-case round (62.5× the ticket at the oracle mark). As inventory compounds (edge + sell-back spread + restock), bigger tickets unlock automatically — high-roller rungs above the live cap stay dimmed until the floor deepens. Pay with ETH or USDG (USDG swaps on-chain at the oracle mark; ~2% headroom refunds in ETH).

After you win

• Instant cash-out. Every degen win lands as stock in your wallet on settle. One tap sells it back at 95% of the live mark, paid in USDG or ETH from the machine bankroll. The 5% spread stays in the bankroll (house revenue); it is reclaimable by the machine's reclaimer.
• Mint a Stonk Certificate. sealIntoCertificate(roundId) seals 100% of the prize in a numbered polymer deed with its own ERC-6551 vault — no spread taken. Hold it, trade it, gift it, or redeem any time (redeem burns the deed; cashing out after still pays 95%).

How Stonk Certificates work

VRNG on Robinhood Chain — powered by DERP

Robinhood Chain has no Chainlink VRF on the production path, so the Box draws randomness from DERP: miners publish certified entropy prints to an onchain conductor, and every machine reads its random words from that shared feed. Production machines use 3 prints ahead plus a ~45s settle-delay floor (older builds used 8 prints / 60s). Round time is cadence-bound — typically a couple of minutes; the UI shows a live ETA from mine health. A Chainlink VRF conductor adapter exists for a future migration.

• Commit first, entropy later. A pull commits to a word that does not exist yet — derived from future certified prints. Neither the player, the house, nor any single miner can choose the outcome. Once the deciding print lands, the ticket cannot be cancelled to dodge a bad roll.
• Anyone can verify. wordOf(id) equals previewWord(id) once fulfilled. Anyone can recompute the multiplier; our keeper (or any third party) can call fulfill to land the word.
• Fails closed. If certified prints thin out or stall, machines stop selling new tickets (FloorUnhealthy). Settles, rescues, redeems, and cash-outs always go through. A pull whose word never lands can be rescued for a full ticket refund after 48 hours.
• Inventory-bound concurrency. Open rounds reserve stock; when free stock cannot back a new ticket the bell greys out until rounds settle or the restock keeper bridges ETH and converts bankroll to stock. Pulls never sell an uncovered prize.

Prize table (bytecode)

Worst roll pays 0.70× — a player can never be down more than 30% on a single pull. RTP 90.00%.

House edge & fee map

Every degen ticket carries a 10% house edge, burned into machine bytecode at launch:

• 2.5% creator — pushed at settle (official machines set creator = StockBooster, so this also lands on Clock In)
• 2.5% StockBooster — Clock In pot for activated brokers
• 5% protocol — accrues in the machine; withdrawable only to the immutable treasury above the bankroll floor
• 5% sell-back spread — stays in machine bankroll; reclaimable by the reclaimer (treasury on official machines, creator on community ones). Community reclaimers cannot touch protocolAccrued.
• Counter — flat $2 ($1 booster / $1 treasury), no percentage. Royalty 3.33% on deed secondary sales to treasury.

Broker Box revenue lands in the same Clock In pot as trade fees — holders control what their share pays out in through their Clock In v2 election on the Activate desk.

Deploy your own box (coming soon)

Permissionless launches via the factory are next. One factory call will spin up a new machine pointed at approved stock-token routes and USD feeds, already wired to the shared DERP conductor, swap router, and deed collection. Community launchFor credits the creator with the 2.5% creator share and makes them the reclaimer. Official launch routes creator fees to Clock In. Launches stay curated so junk tokens and junk feeds cannot mint official-looking deeds. Machines migrate VRNG in place via a 3-day timelock (proposeConductor / commitConductor); setMinterRegistrar is redeployable so new machine generations can join the same certificate collection.

Core contracts (mainnet)

Never wire the canonical ERC-6551 registry into a Stonk Certificate deploy — only the project's initializing registry clones + initializes vaults atomically. Full deploy state: contracts/gacha/deployments.mainnet-production.json.
