Pound is a launch layer on top of pons v2, the bonding-curve launchpad on Robinhood Chain. It adds two things: launching from a post on X, and pairing every token with a tokenized stock.

Overview

Cashtags. X’s Smart Cashtags turn $AAPL into a live chart with a Trade button that routes to brokerages, and let anyone paste a contract address to pull up a token. Pound speaks the same language: the pair you launch with is a cashtag, every token page is addressable by its contract address, and share cards carry live price and progress.

A launch is a fixed-supply ERC-20 (1,000,000,000 tokens, 18 decimals) minted straight into its own bonding-curve contract. Traders buy and sell against that curve in the pair asset — a Robinhood stock token such as AAPL, or ETH/USDG — until the curve sells out. Then liquidity migrates into a permanently locked Uniswap v4 pool and the token keeps trading there.

Pound never takes custody of anything. Launches from X are submitted by the Pound relayer, which pays the 0.0005 ETH launch fee; launches from a wallet are signed by you. All trading happens directly against pons contracts.

The post format

@pounddotfamily $TICKER - Coin Name $AAPL

• $TICKER — 1 to 13 letters or numbers. Becomes the token symbol.
• Coin Name — up to 32 bytes of UTF-8 after the dash.
• $PAIR — the stock cashtag to price the curve in, written as a Smart Cashtag so the post appears in that cashtag’s feed on X (#AAPL still works). Omit it and the pair defaults to $ETH.
• Already posted? Paste the post link on the Launch page — Pound reads public posts without any X login.
• The post travels with the coin. Its URL is written into the token’s on-chain description, set as the coin’s X link on pons, and shown on the Pound token page; the coin’s website link points back at the post’s coin (/x/<post id>).
• Image — the first JPG, PNG or WebP attached to the post becomes the coin artwork.
• One accepted post creates at most one coin. Edited, quoted or reposted posts are ignored; rate limits apply per account.

Pairs

Only assets pons has explicitly approved can be used as a pair. Today that is ETH, USDG and a growing list of Robinhood stock tokens — the Pairs page reads the live list from the factory. Each pair has its own phantom reserve and graduation threshold, set by pons and pinned into every launch at creation.

Stock tokens are standard ERC-20s with 18 decimals and a per-asset Chainlink price feed. They give economic exposure to the underlying equity only, with no shareholder rights, and Robinhood restricts them in the US, Canada, the UK, Switzerland and the other jurisdictions listed at docs.robinhood.com/rhj.

Bonding curve & graduation

The curve is constant-product with a virtual (“phantom”) quote reserve that sets the opening price. Marginal price is quoteReserve ÷ tokenReserve; progress to graduation is realQuoteReserve ÷ graduationThreshold. Roughly 5/7 of supply is sold on the curve; the remaining 2/7 is swept into the pool at graduation, where 10/49 of supply is permanently locked and 4/49 goes to the launch locker.

A 99% snipe tax applies to buys in the first five seconds after launch and decays exponentially to zero. The launching wallet and up to 32 exempt wallets skip it. Selling is never snipe-taxed.

Fees & creator payouts

• Launch fee: 0.0005 ETH plus gas, paid to pons. For X launches the Pound relayer covers it.
• Trading fee: 1% of the quote leg on every curve trade, and on pool trades after graduation via the pons hook. The on-chain fee policy sends 30% to the protocol and 70% to the creator fee recipient. If the creator turns buybacks on, half of the creator share is spent buying the token back instead, and those tokens vest over five years.
• Creator tax: optional, up to 10%, fixed at launch, paid entirely to the creator. Wallet launches can set it; X launches use 0%.
• Payout asset: fees are charged in the pair asset — a launch paired with #NVDA pays out in NVDA tokens.

Claiming as an X account

For launches from X, the creator fee recipient is initially the Pound relayer. Fees accrue in the pons fee escrow per launch and never leave it until claimed. To take control, sign in with the X account that posted, link a wallet, and Pound calls transferCreatorFeeRecipient to hand the launch to you — it takes effect immediately and moves any buyback vesting with it. From then on you claim directly from the escrow with your wallet.

Launching from a wallet

The Launch page calls launchAndBuy on the pons router in a single transaction: launch, optional first buy, and snipe-tax exemption for your wallet. For a stock or USDG pair you approve the router for the first-buy amount and send only the launch fee as value; for ETH you send fee + buy amount. Economics are pinned with previewLaunchEconomics so the transaction reverts if terms change between quote and submission.

Trading from X

X’s Trade button routes cashtag taps to partner exchanges, and Kraken’s DEX trading (in the Kraken app and on Kraken Pro) covers Robinhood Chain: tokens that aren’t listed on Kraken are bought through on-chain liquidity into a self-custodial embedded wallet, with a 1% fee. Graduated Pound tokens have a Uniswap v4 pool, which is what that routing needs; bonding-curve tokens become routable at graduation.

Every token page shows the contract address, the Uniswap v4 pool id and Kraken’s entry points, plus a one-tap “post with address” test: X’s asset panel attaches to pasted contract addresses on some chains today, so posting a Robinhood Chain address is how we find out when the panel lights up for this chain. Links opened inside X’s in-app browser offer “Open in wallet” (Coinbase Wallet, MetaMask, Phantom, Trust, OKX) because that browser cannot connect a wallet, and /trade/$TICKER?amount=0.05 lands on a token page with the trade prefilled — the entry point a Trade button can target.

Contracts

Risks

• Launched tokens are memecoins with no intrinsic value. Most never graduate and most lose value.
• Pairing with a stock token adds equity price exposure on top of curve volatility; a launch paired with #TSLA moves with TSLA and with its own demand.
• Stock tokens are restricted in several jurisdictions. It is your responsibility to know whether you may hold them.
• pons v2 has no completed audit yet — its own docs say to treat the contracts as unaudited until reports are published. pons, Pound and Robinhood Chain are separate projects; Pound is not affiliated with X Corp, Robinhood Markets or Pons-Labs.
