A Prism coin trades in an ordinary Rhea DCL pool, so it can be bought on the coin's page, on Rhea, through any router or aggregator that reads Rhea, or from a Telegram bot.

On the coin page

Pick buy or sell, type an amount, and confirm in your wallet. The panel quotes the swap off Rhea itself and sets a minimum output from your slippage tolerance. If the pool cannot fill the swap within it, the swap is refused and your tokens come straight back in the same transaction.

A NEAR-paired coin is bought with plain NEAR: the wallet wraps it and sends it to Rhea in one receipt, and a sale pays you back in plain NEAR.

A first buy of a coin also registers your wallet on it (a one-time storage deposit of about 0.00125 NEAR), in the same prompt.

From anywhere else

The pool id is coin | pair asset | 10000. Rhea's app, DexScreener and GeckoTerminal list it within minutes of the first trade; the coin page links to all three.

From another chain

Every coin page has a Buy from any chain card. Pick what you hold (ETH on Ethereum, Base or Arbitrum; USDC on Base, Arbitrum, Ethereum or Solana; SOL; BTC), an amount, the NEAR account to receive on — or your EVM address, which receives on its NEAR twin account controlled by the same wallet — and a refund address on your chain.

The card gives you a deposit address. Send exactly the amount shown before the deadline. NEAR Intents swaps it into the coin's pair asset and delivers it to the Prism router, which buys the coin in its pool and sends it to you. If anything fails on the way — the price moved past the slippage bound, the coin is not live — the input comes back: on your chain if the swap did not complete, as the pair asset on NEAR otherwise. The card follows each step until the coin lands.

What a swap costs

1% of the swap, taken by the pool. A taxed coin also charges its tax on every buy and every sale; the quote shown is what you receive after it. See Fees, tax and dividends.
