Developer guide
This guide introduces all the concepts needed to build applications that use Walrus as a storage or availability layer. The overview provides more background and explains in more detail how Walrus operates internally.
This developer guide describes the following:
- Components of Walrus of interest to developers that wish to use it for storage or availability.
- Operations supported through client binaries, APIs, or Sui operations.
- The Sui structures Walrus uses to store metadata, and how they can be read from Sui smart contracts, or through the Sui SDK.
Refer again to the glossary of terms as a reference.
The current Devnet release of Walrus and Walrus Sites is a developer preview intended to showcase the technology and solicit feedback from builders. All storage nodes and aggregators are operated by Mysten Labs and all transactions are executed on the Sui Testnet and use Testnet SUI which has no value. The state of the store can and will be wiped, at any point and possibly with no warning. Do not rely on this developer preview for any production purposes, it comes with no availability or persistence guarantees.
Furthermore, encodings and blob IDs may be incompatible with the future Testnet and Mainnet and developers will be responsible for migrating any Devnet applications and data to Testnet. Detailed migration guides will be provided when Testnet becomes available.
Also see the Devnet terms of service under which this developer preview is made available.
