Receiving a wallet address vs contract address using V3Pool

[Luca-Blight]

sample of the code that generates the address:

 const poolAddresses = validTokenPairs.map(([tokenA, tokenB]) =>
    V3Pool.getAddress(tokenA!, tokenB!, feeAmount!)
  );

  const poolInfoPromises = poolAddresses.map((poolAddress, index) => {
    const [tokenA, tokenB] = validTokenPairs[index];
    console.log(`Fetching pool data for address: ${poolAddress}`);
    console.log(`Token A: ${tokenA?.address}`);
    console.log(`Token B: ${tokenB?.address}`);
    console.log(`Fee Amount: ${feeAmount}`);

    return getPoolInfo(poolAddress, feeAmount).catch((error) => {
      console.error("🚀 ~ poolAddress, failed to fetch pool data:", poolAddress, error);
      return undefined;
    }); 

token info used and address returned:

The getAddress method computes the plausible pool address from the parameters provided (the pool does not necessarily need to exist). You need make sure that such a pool is initialized.
