Introduction

The Astral Protocol is a geospatial extension for Ethereum. It adds location data structures and spatial computations to the decentralized web. Our aim is to enable a new kind of open, reliable, and opt-in location-based web.

Astral doesn't seek to replace existing geospatial technologies. Instead, we ask how we can enhance them with Web3 design principles — openness, durability, and user dignity. Our aim is to bridge established geographic tools and standards with the emerging decentralized web, opening new possibilities for how we create, share, and trust spatial information.

Our goal is to unlock a new category in Web3: location-based apps and protocols.

Key Components​

Location Protocol v0.1 live​

A structured way of representing geographic information clearly and consistently, designed for the decentralized web. It includes:

  • location attestations
  • flexible data control
  • extensible spatial format support
  • universal spatial representation
  • rich media attachments
  • extensible verification framework

Location Protocol

Spatial.sol R+D​

Spatial.sol

A suite of Solidity contracts that bring geospatial functionality to the EVM.

  • Spatial operations: Calculate distances, determine containment, detect intersections between geometries
  • Efficient indexing: Organize spatial data for rapid retrieval and analysis
  • Location-aware logic: Enable smart contracts with geographic rules like "execute only if within city limits"

Spatial Attestation Framework​

The Astral Spatial Attestation Framework provides a toolkit for developers to build with location data in the Ethereum ecosystem.

Astral SDK in dev​

SDK Repo →

A TypeScript client library that simplifies working with spatial data in decentralized applications — built with EAS and ethers.js:

  • Streamlined workflows: Create, sign, publish, and retrieve location data with minimal code
  • Verification tools: Evaluate location claims against customizable standards of evidence
  • Media processing: Consistent handling of diverse media formats attached to location data

Astral API live beta​

API Docs →

A unified interface to the decentralized geospatial web:

  • Comprehensive indexing: Tracks and organizes location data published through Astral
  • Optimized access: Preprocesses geospatial information for efficient retrieval
  • Industry-standard interfaces: Serves data through familiar channels like GraphQL and OGC API Features

Astralscan (in design)​

A web interface for exploring and interacting with location data on Ethereum:

  • Visual exploration: Browse and visualize location data on an interactive map
  • Data verification: Inspect and validate location claims and their supporting evidence
  • Rich media support: View photos, videos, and other media attached to location data
