I am exploring crypto token development and would appreciate some advice from people familiar with blockchain projects. What should come first: defining the token's purpose, selecting a blockchain network, designing tokenomics, or developing the smart contract?

I have also been looking at providers such as Techzarinfo to understand the technical side of custom blockchain projects. I want to avoid making decisions that could create problems later with security, transaction costs, or scalability. If you have experience launching a token, what would you do differently if you were starting again today?
