The project comprises of:

• An on-chain multi-sig wallet program
• A client library that helps construct requests to the multi-sig wallet program

The multi-sig wallet program provides the following instructions:

• Initialize wallet and add initial key
• Add new owner public key with corresponding weight (requires authorization)
• Remove owner (requires authorization)
• Invoke any instruction to another program (requires authorization)

Each owner public key has its own weight (0~1000). Any authorized instruction requires the total signature weight to be at least 1000.

The following dependencies are required to build and run this example, depending on your OS, they may already be installed:

• Install node
• Install npm
• Install docker
• Install the latest Rust stable from https://rustup.rs/
• Install Solana v1.4.7 or later from https://docs.solana.com/cli/install-solana-cli-tools

This example connects to a local Solana cluster by default.

Enable on-chain program logs:

$ export RUST_LOG=solana_runtime::system_instruction_processor=trace,solana_runtime::message_processor=debug,solana_bpf_loader=debug,solana_rbpf=debug

Start a local Solana cluster:

$ npm run localnet:update
$ npm run localnet:up

View the cluster logs:

$ npm run localnet:logs

Note: To stop the local Solana cluster later:

$ npm run localnet:down

$ npm run build:program

$ npm run start

Solana maintains three public clusters:

• devnet - Development cluster with airdrops enabled
• testnet - Tour De Sol test cluster without airdrops enabled
• mainnet-beta - Main cluster

Use npm scripts to configure which cluster.

To point to devnet:

$ npm run cluster:devnet

To point back to the local cluster:

$ npm run cluster:localnet
