DAT - Distributed Access Token

Document

• DAT Run Online
• What is DAT
• Example
• AI Vibe Coding

Requirements

• Node.js 24 or newer. The encoders use Uint8Array.fromBase64/toBase64/fromHex/toHex, which land in Node 24; on Node 20/22 every encode and decode throws a TypeError.
• ESM only. This package ships a single ES module entry point — import it with import { ... } from 'saro-dat'. There is no CommonJS (require) build.

Support Platform

• Rust
• Java, Kotlin
• Javascript, Typescript
• C#
• Python
• Go
• Ruby
• C/C++ (Vcpkg)
• Cert(Key) Server (Docker)
