Can I call the smart contract directly? How should I call it

[yihau]

sure. It depends which program you are interacting with. The main idea is to compose transaction if you want to call smart contract (in solana we called it program). FYI

A transaction = many signatures + a message
A message = many instructions + recent blockhash

you can treat every instruction equals a function in the program.

you can take a look at

https://github.com/solana-labs/example-helloworld https://dev.to/cogoo/solana-how-to-send-custom-instructions-via-instruction-data-4g9g

to learn how to compose your own instruciton.

How do I call the Hello World function in rust from go-client? https://github.com/solana-labs/example-helloworld

Oh. I think I should add some examples for interacting with custom program!

[panchuprodhan]

Yes, that should be helpful!

That would be amazing thanks.

Hi, is there anyone example to call a custom program available now? Or can I call a smart contract directly developed by anchor framework?

added three pages for basic concept
