Deploy regular solana (not anchor) on mainnet

Question

I'm looking to deploy a regular solana program written in Rust (not anchor) on mainnet. For some reason I can't rewrite it using anchor solana. I have searched online and all failed. Does anyone know the detailed answer?

Answer 1

You use cargo build-sbf or cargo build-bpf (depending on you used version) to build your program. That will build a .so file in your target/deploy directory. From there you can use the solana program deploy command to deploy your program. To see relevant info about that run solana program deploy --help.

Answer 2

1. Run cargo build-sbf or cargo build-bpf (depending on version) to build your program. That will build a .so file in target/deploy directory.

2. To deploy on mainnet, you need a wallet containing real SOL. Copy wallet private key

and paste it in the javascript code below

const bs58 = require('bs58')
const fs = require('fs')
b = bs58.decode(
    'your private key'
)
j = new Uint8Array(
    b.buffer,
    b.byteOffset,
    b.byteLength / Uint8Array.BYTES_PER_ELEMENT
)
fs.writeFileSync('key.json', `[${j}]`)

3. Try run above code to create key.json file

4. Run solana config set --url https://api.mainnet-beta.solana.com

5. Run solana program deploy -k *path_to_key.json* *path_to_.so_file*
