Introduction
Stoa is the PropAMM hub on Elysium: pools priced live by professional makers, with every swap checked against other venues before you sign.
What Stoa is
Most AMMs price a trade with a fixed formula. On Stoa, every pool is priced by makers who post bid and ask quotes on-chain, block after block. That is called a proactive AMM, or PropAMM. Because Elysium produces a block every 100–200 ms, makers can update prices several times a second at low cost.

How Stoa launches
Stoa launches router first. On day one every swap is checked against Uniswap on Elysium and filled there, so trading works before any maker pool holds inventory. Maker pools join the same router as curators come online, and win whenever they quote a better price. Nothing changes for you as a trader.
