multisig-lite

A native SOL multisig on-chain program for Solana Blockchain.

Currently, there are five instructions to provide the queued multisig transfer operation:

1. create
2. fund
3. create_transfer
4. approve
5. close

Examples

Here is how to create a new multisig account on-chain.

Please refer to the multisig_lite::multisig_lite module level documentation for the other instructions' example.

use std::rc::Rc;

use solana_sdk::commitment_config::CommitmentConfig;
use solana_sdk::pubkey::Pubkey;
use solana_sdk::signature::read_keypair_file;
use solana_sdk::signer::Signer;
use solana_sdk::system_program;

use anchor_client::{Client, Cluster};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let url = Cluster::Devnet;
    let funder = Rc::new(read_keypair_file(
        shellexpand::tilde("~/.config/solana/id.json").as_ref(),
    )?);
    let opts = CommitmentConfig::processed();
    let pid = multisig_lite::id();
    let program = Client::new_with_options(url, funder.clone(), opts).program(pid);

    // Gets the PDAs.
    let (state_pda, state_bump) =
        Pubkey::find_program_address(&[b"state", funder.pubkey().as_ref()], &pid);
    let (fund_pda, fund_bump) = Pubkey::find_program_address(&[b"fund", state_pda.as_ref()], &pid);

    // Creates a multisig account.
    let sig = program
        .request()
        .accounts(multisig_lite::accounts::Create {
            funder: funder.pubkey(),
            state: state_pda,
            fund: fund_pda,
            system_program: system_program::id(),
        })
        .args(multisig_lite::instruction::Create {
            m: 2, // m as in m/n.
            signers: vec![funder.pubkey(), Pubkey::new_unique(), Pubkey::new_unique()],
            q: 10, // transfer queue limit.
            _state_bump: state_bump,
            fund_bump,
        })
        .signer(funder.as_ref())
        .send()?;

    Ok(())
}
