Execution of swap

If you specified the parameters a, b, c then the answer will return the calldata property. To perform this swap you just need to use our SwapRouter02

SwapRouter02 address: 0x496e305C03909ae382974cAcA4c580E1BF32afBE

Make sure you do the approve before the action in the example

 cast send 0x496e305C03909ae382974cAcA4c580E1BF32afBE "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"
