if you are dev,i recommend you use code to estimate gas instead of a fixed value,

thanks for replying, we are building application which will be deployed on multiple evm based chains.
We will try with above method sure.

Still we are curious to know when or what kind situation this 1.5M may not be sufficient and the transaction might revert due to insufficient gas.

I don't have data, but some complex defi txs might exceed this,like flashloan? or loop loan.bridge or contract deploy.
estimate gas and plus 10-20% overhead is the best choice since you wan't let user waste gas if txs failed
