Pair

Any Robinhood token with $1k+ of DEX liquidity can be a coin's pair on Pair, and new pools are picked up every 10 minutes. That covers the stock tokens (NVDA, TSLA, SPY, QQQ, COIN, MSTR and the rest), USDG, and the community coins that migrated off their launchpads. A coin paired with NVDA is priced in NVDA and bought with it, at the same 1% fee as an ETH pair, and its creator is paid in NVDA. Paste any token address into the pair search on the launch page to check it.

Coin pages on Pair now show both halves of a move: the coin against its pair and the pair against ETH, with the chart switching between USD, ETH and the pair. Explore now groups coins by pair, ranked by 24h volume, with tabs for Robinhood, Solana, Ethereum, Base and BNB Chain; coin links also preview on X and Telegram with the coin's image, pair, market cap and chart. pair.cx/explore

A Pair coin can never trade below its launch price in its pair. The whole supply starts in one Uniswap v4 position from the starting price upward, minted as a position NFT to 0x...dEaD in the launch transaction (100% of the launch liquidity burnt). Sellers can only sell back what was bought, so if every holder sells, the pool lands back on its starting price. Graduation at 4.15 ETH worth bought leaves the pool, the position and the floor exactly where they are, and trading never pauses for a migration. The floor is counted in the pair: a coin paired with USDG has a floor in dollars, a coin paired with pBTC a floor in BTC.

A coin's price in ETH is its price in its pair times the pair's price in ETH, and that second number has always come with the chain. The article goes through how Pair lets a creator pick it from five chains: one buy followed through the contracts, where every price comes from, and each attack we ran against the pools on a fork of Robinhood mainnet (pump the asset 5% and sell: 0.969 ETH back on 1 ETH, the same as a calm round trip).

What one buy of a coin paired with any cross chain pair does, inside a single Robinhood Chain transaction: 1. Your ETH enters the cross chain pair pool. Let's say the cross chain pair is PSOL - its hook reads SOL's and ETH's prices, checks both are fresh, and sells you pSOL at the higher of SOL's live price and its 30-minute average; 1.5% stays in that pool's ETH reserve. 2. The pSOL enters your coin's own Uniswap v4 pool, which takes 1% (half to the creator, claimable from the coin page) and sends you the coin. A sale runs the same two pools backwards and pays ETH from the reserve at the lower of the two prices, so a short spike on SOL's markets pays nothing to whoever bought before it. Nothing is bridged: the only thing that crosses from Solana is the price.

A coin's price in ETH is two prices multiplied: the coin against its pair, and the pair against ETH. Until now the chain picked that second half for every coin on it (SOL on Solana, BNB on BNB Chain, ETH on Robinhood). Pair is live on Robinhood Chain, and the creator picks it. Pair your coin with ETH, any Robinhood token with liquidity (USDG, stock tokens, PONS), or one of 344 Pair tokens that follow SOL, BNB, PEPE, BONK and the top coins of Solana, Ethereum, Base and BNB Chain. When SOL runs, every coin paired with pSOL runs with it in ETH; buyers still pay with ETH, in one transaction, on one chain. CA: 0x3024d06034a3fc1faf85f11fabb491c25ff7e5fd pair.cx
