DEXes

DEX deployments on Stable for spot trading, liquidity provision, and on-chain routing. Stable is on the Official Uniswap v3 Deployments List: the Uniswap v3 contracts on Stable are governance-recognized as canonical and are routed through Stable Swap as the default frontend.

Quoting a swap

Quoter V2 returns the expected output for a given input without executing a trade. Use it from any EVM tooling pointed at Stable's RPC.

Replace <TOKEN_IN>, <TOKEN_OUT>, <AMOUNT_IN>, and <FEE> (one of 100, 500, 3000, 10000) with the values for the pool you're quoting. For application integration, prefer the Uniswap v3 SDK or the Universal Router pointed at the addresses above.
