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.

cast call 0xb070179E7032CdA868b53e6C1742F80c9e940d1A \
  "quoteExactInputSingle((address,address,uint256,uint24,uint160))(uint256,uint160,uint32,uint256)" \
  "(<TOKEN_IN>,<TOKEN_OUT>,<AMOUNT_IN>,<FEE>,0)" \
  --rpc-url https://rpc.stable.xyz

(amountOut, sqrtPriceX96After, initializedTicksCrossed, gasEstimate)

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.
