Walrus just leveled up (again). The Walrus TypeScript SDK now ships with two massive upgrades: ✅ Upload Relay for faster, more reliable uploads ✅ Native Quilt support for bundling small files like a pro Let's dive into what's new, and why it matters for devs 👇

Walrus is powering a growing wave of onchain data apps. Since Mainnet launch: 📦 869+ TB stored 💡 Used by all 4 winners of Programmable Storage at Sui Overflow 🛠️ 35+ builds at ETHGlobal Cannes 👀 Chosen by teams like @GetSwarmed, @TradePortxyz, @Linera_io

🧠 First, a quick reminder of why the Walrus TypeScript SDK exists. It's the de facto toolkit for building experiences where users manage their own data - paying for storage from their personal wallets and owning their data like assets. If you're building apps where wallet = user = owner, this SDK is for you.

The upgraded TypeScript SDK is built for real-world apps like: 🧾 Wallet-based storage flows 📱 Mobile & web experiences 📶 Resilient uploads in low-connectivity conditions 💳 User-pays-onchain models Now let’s talk Upload Relay.

⚡ Upload Relay = The performance lane for uploads It takes the load off client apps by: - Handling data distribution to nodes - Making uploads more reliable on shaky networks - Simplifying infra (no need to run full cloud stacks) Your users = happy. Your infra = lean.

🔐 Don't want to trust a 3rd party? You don’t have to. Upload Relay is: - Lightweight enough to self-host - Detectable if compromised - Wallet-compatible (supports SUI payments) Want to monetize? Relays can accept tips in any Sui-compatible token.

Now with Quilt support too! The new WalrusFile API supports under one common abstraction both: 📂 Large blobs 🧶 Small bundled files (via Quilt) Making it dead simple to build apps that store any data type - from AI models to doc signers.

🦭 Walrus is here to make data uploads seamless, resilient, and dev-friendly. The new SDK + Relay unlock a world of apps: From cross-chain CDNs and GitHub backups to zk-whistleblowing and decentralized AI. Build what's next on Walrus.
