What Is Walrus?

Walrus is a decentralized storage and data availability protocol designed to store large, unstructured "blob" data such as video files, images, AI models, datasets, and NFT assets. Traditional blockchains are expensive and impractical for storing large files, while centralized cloud storage requires trusting a single provider. Walrus aims to sit between these extremes, offering decentralized, verifiable, and programmable storage at a cost that scales for large data. It is important to distinguish this project from unrelated namesake meme tokens; the WAL described here is the storage protocol from the Sui ecosystem.

Walrus was built by Mysten Labs, the same company that created the Sui blockchain. George Danezis, a co-founder and Chief Scientist at Mysten Labs and a professor of computer security at University College London, is among the project's co-founders and authors of the Walrus whitepaper. The protocol reached mainnet, and the WAL token generation event took place, on March 27, 2025. Walrus is closely tied to Sui: it uses Sui Move smart contracts as its coordination and control layer, so storage on Walrus can be programmed, tracked, and governed directly on Sui.

The technical core of Walrus is an erasure-coding scheme the team calls "Red Stuff," a two-dimensional encoding approach. Rather than replicating every file in full across many nodes (which is costly), Red Stuff splits a blob into fragments called slivers and distributes them across the network's storage nodes. The data can be fully reconstructed from a subset of these fragments, which lets Walrus achieve high availability at a replication factor of roughly 4.5x, far lower than the overhead of full replication. The design is self-healing, meaning the network can recover lost fragments and restore data when individual nodes fail or drop offline.

The WAL token is native to the Sui blockchain. Its Sui contract type is 0x356a26eb9e012a68958082340d4c4116e7f55615cf27affcff209cf0ae544f59::wal::WAL, which can be viewed through Sui block explorers such as Suiscan or SuiVision. WAL serves several functions in the protocol: users pay in WAL to store data, storage node operators stake WAL to participate and earn rewards, and holders use WAL to vote on governance decisions. The protocol also includes mechanisms that burn tokens through penalties, reducing supply under certain conditions.

WAL has a maximum supply of 5 billion tokens, with roughly 2.457 billion in circulation. At that circulating supply the market capitalization is approximately 77 million US dollars, giving Walrus a fully diluted valuation in the range of 155 million US dollars. The token launched with a market debut around March 2025 and reached its peak price in roughly May 2025, but its price has declined substantially since that peak, in line with much of the broader altcoin market during that period.

Walrus has attracted significant investment and adoption. In March 2025, the Walrus Foundation announced a 140 million US dollar token sale led by Standard Crypto, with participation from a16z crypto, Electric Capital, Franklin Templeton, and others. By 2025 the network had grown past petabyte scale in stored data and reported more than 200 projects building on it. As of the current writing, no security hacks or exploits of the protocol have been publicly reported. Investors should be aware, however, of token unlock schedules: a large investor unlock began on March 27, 2026, releasing roughly 350 million WAL after a one-year cliff, which increases the circulating supply and can create selling pressure.

Getting Started With Walrus

Getting started with Walrus involves setting up a Sui-compatible wallet and acquiring WAL tokens, or building on the protocol as a developer:

  1. Step 1: Set up a Sui-compatible wallet such as the Slush wallet (formerly Sui Wallet), Suiet, or Phantom's Sui support. WAL is a native token on the Sui blockchain.
  2. Step 2: Purchase WAL on a centralized exchange that lists it, or acquire SUI and swap it for WAL on a Sui decentralized exchange.
  3. Step 3: Transfer your WAL to your own Sui wallet for self-custody.
  4. Step 4: Optionally, stake WAL with a storage node operator to help secure the network and earn rewards, or use WAL to pay for storing data on Walrus.

For developers, Walrus provides documentation, a command-line client, and SDKs for storing and retrieving blobs, along with Sui Move interfaces for building storage-aware applications. A cost calculator is available to estimate storage pricing before committing data.

How to Get a Walrus Wallet?

WAL is a native token on the Sui blockchain, so it can be stored in any wallet that supports Sui assets:

Slush (Sui Wallet)

Slush, formerly known as the Sui Wallet, is the official wallet developed by Mysten Labs for the Sui ecosystem. It is available as a browser extension and mobile app, and supports SUI, WAL, and other Sui-based tokens with native staking and dApp connectivity.

Suiet

Suiet is a popular open-source wallet dedicated to the Sui blockchain, available as a browser extension and mobile app. It supports all Sui-based tokens including WAL and offers a straightforward interface for managing assets and connecting to Sui applications.

Phantom

Phantom, widely known as a Solana wallet, has added support for the Sui blockchain. It can hold and manage Sui-based tokens such as WAL alongside assets from other chains, making it a convenient multi-chain option for users who already use Phantom.

How to Buy Walrus?

WAL is available on both centralized and decentralized exchanges. Because it is a Sui-native token, buyers should ensure their wallet and withdrawal network are set to Sui:

Centralized Exchanges

WAL is listed on several centralized exchanges, including Binance, Bybit, KuCoin, Gate.io, and LBank. Most offer WAL against stablecoins such as USDT. After purchasing, you can withdraw WAL to a Sui-compatible wallet by selecting the Sui network for the transfer.

Decentralized Exchanges

On the Sui blockchain, WAL can be swapped on Sui-based decentralized exchanges such as Cetus and Turbos Finance. Connect a Sui wallet, then trade SUI or a stablecoin for WAL directly on-chain. Always verify the WAL token contract address before swapping to avoid imitation tokens.

Latest Walrus News

Since its March 2025 mainnet launch and token generation event, Walrus has focused on positioning itself as a verifiable data platform for AI builders, emphasizing storage that users control across apps, providers, and AI agents. The network passed petabyte scale and reported more than 200 projects building on the protocol during 2025, though the WAL token's price fell substantially from its peak around May 2025.

A notable recent development is the investor token unlock that began on March 27, 2026, releasing roughly 350 million WAL after a one-year cliff. Unlocks of this size expand the circulating supply and can add selling pressure, so prospective holders should factor the ongoing vesting schedule into their expectations alongside the protocol's continued growth in stored data and integrations across the Sui ecosystem.
