Reading the chain

One ocean,one pool,every shore.

PANTHA trades in a single Uniswap v4 pool on Ethereum. Base reaches the same pool in rounds through Stargate. Both shores meet one price, because there is one place where the price is made.

Panthalassa, the one ocean around Pangaea The supercontinent Pangaea drawn in dots, the single ocean around it, and the one pool as a red point in that ocean. A solid route reaches it from the Ethereum shore; a dashed route reaches it from the Base shore, in rounds through Stargate. Base, in rounds through Stargate Base Ethereum, direct Ethereum the one pool PANTHALASSA PANGAEA

Show the route from

Two shores, one pool. Ethereum swaps in it directly; Base orders cross to it in rounds and come home filled.

The problem

A coin that opens a pool on every chain splits its liquidity into shallow pools, each making its own price.

What it causes

Arbitrage pulls the prices back together, and every gap it closes is paid for by the pools. Pangea opens a coin in five pools on five chains and works this way.

Panthalassa

One pool, holding the whole billion from the day it opened. Nothing to arbitrage between shores, and every seller, on either chain, is paid from the full depth.

Swap in the pool

Swap ETH for PANTHA, or back, in the one pool, in one transaction. You choose the slippage; the page quotes the pool and sets your least amount out.

  • 1% of the ETH side of every swap goes to the owner.
  • The Uniswap app cannot route this pool, because its hook takes the 1% through return deltas. The trade page builds the swap itself, through Uniswap's Universal Router.
Trade on Ethereum
Base, in rounds

Leave an order in the Shoal

Leave a buy or a sell on Base with your own price limit. Orders gather in rounds of up to 64; anyone closes a round; it crosses to the pool through Stargate, every order fills against its own limit, and the round comes home.

  • Buyers get Base PANTHA and any ETH that did not buy. Sellers get ETH and any PANTHA that did not sell.
  • Least buy 0.0005 ETH, least sell worth the same. An order pays its share of the round's cost, never more than 2% of what filled, and nothing if it did not fill.
