Toolchain

Node.js

The workspace targets Node.js 22.18.0 or ≥ 24.12.0. Use nvm or fnm to manage versions:

# fnm (recommended — fast, written in Rust)
curl -fsSL https://fnm.vercel.app/install | bash
fnm install 24
fnm use 24
node --version  # v24.x.x

Sui and Walrus CLIs — suiup

All Sui and Walrus binaries are managed by suiup, a version manager analogous to rustup:

# Install suiup
curl -sSfL https://raw.githubusercontent.com/MystenLabs/suiup/main/install.sh | sh
# suiup installs to ~/.local/bin/suiup; symlinks at /usr/local/bin/sui and /usr/local/bin/walrus

# Install the testnet-channel binaries
suiup install sui@testnet
suiup install walrus@testnet

# Pin the Sui version the Move packages are tested with in CI
suiup install [email protected]
suiup switch [email protected]

# Verify
sui --version     # sui 1.80.0-…
walrus --version

Checking for updates

suiup show    # installed and active versions
suiup status  # check whether newer testnet releases are available

When a new testnet release ships, install and switch:

suiup install [email protected]
suiup switch  [email protected]
suiup install [email protected]
suiup switch  [email protected]

Sui wallet

Install any Sui-compatible wallet browser extension. Slush is recommended for development.

Create a new address for testnet work:

sui client new-address ed25519
# Copy the address shown and fund it from the testnet faucet

Fund the address from the Sui testnet faucet.

Repositories

Each package is a standalone repository with its own lockfile — there is no monorepo install. Clone what you need and work in it directly:

git clone https://github.com/meddleware-org/sealed-storage-client.git
cd sealed-storage-client && npm install && npm test && npm run type-check

Apps depend on the SDKs through npm; to develop an app against an unpublished SDK change, use npm link (or an overrides entry pointing at a local path) in the app.
