Nova Multisig - Rust SDK

A Rust SDK for interacting with the Nova Shield fork of Squads Protocol v4 on Solana.

Now compatible with Solana 2.2+!

About

This is the official Rust SDK for the Nova Shield multisig protocol - a fork of Squads Protocol v4. The Nova Shield fork maintains the same robust multisig functionality while being deployed to Nova Shield's custom program addresses.

Features

• ✅ Complete multisig transaction support
• ✅ Proposal creation and voting
• ✅ Vault transaction management
• ✅ Batch operations
• ✅ Config transactions
• ✅ PDA (Program Derived Address) utilities
• ✅ Full type safety with Rust

Installation

Add this to your Cargo.toml:

[dependencies]
nova-multisig = "0.2.0"

Quick Start

use nova_multisig::{client, pda, state};
use solana_client::rpc_client::RpcClient;
use solana_sdk::pubkey::Pubkey;

// Initialize RPC client
let rpc = RpcClient::new("https://api.mainnet-beta.solana.com".to_string());

// Get multisig PDA
let create_key = Pubkey::new_unique();
let (multisig_pda, bump) = pda::get_multisig_pda(&create_key);

// Use the client to interact with the multisig
// (See examples for more detailed usage)

Usage Examples

Creating a Multisig

use nova_multisig::state::{Member, Permissions};

let members = vec![
    Member {
        key: member1_pubkey,
        permissions: Permissions::all(),
    },
    Member {
        key: member2_pubkey,
        permissions: Permissions::all(),
    },
];

let threshold = 2; // Require 2 signatures

Working with Proposals

use nova_multisig::state::Proposal;

// Fetch a proposal
let proposal_pda = pda::get_proposal_pda(&multisig_pda, 1);
// Use RPC to fetch and deserialize the account

iOS Integration

This SDK is designed to work seamlessly with iOS applications through Rust FFI. For iOS integration:

1. Build the library as a static lib or cdylib
2. Use UniFFI or cbindgen to generate Swift bindings
3. Create an XCFramework for distribution

See the main repository documentation for detailed iOS integration guides.
