Versions and compatibility

The verified source set

One verified source set exists. The navigator is ready for the next set the moment verified source material for it exists; it never fabricates a historical snapshot to make this selector look fuller.

Verified August 2026 baseline

current verified 2026-08-31 mainnet

Protocol baseline

atomicals-electrumx-1.5.2.0 8df23747835c Atomicals ElectrumX v1.5.2.0, the pinned reference validator behavior for ARC-20 and Atomicals rules.

CLI

atomicals-js-cli 1333565efbfe The JavaScript CLI the command inventory and CLI builder are generated from.

AIP registry

atomicals-aips be08d7856db7 The AIP register snapshot. A proposal existing is not evidence that anything implements it.

Universe runtime

universe-index-atomicals 670030e50071 Universe ARC-20 index and Marketplace v1 authority.

AVM interpreter (beta)

atomicals-avm-interpreter c185e6216a3e Beta interpreter. Version isolation matters most here: nothing in this set describes AVM as deployed.

Documentation build

2026.08 The documentation build that renders this source set.

API contracts

arc20 1.0.0

atomicals-nfts-realms 1.0.0

marketplace-v1 1.0.0

Semantic changes between sets

Diffs are computed between verified sets only. Protocol rules, OpenAPI operations, JSON Schemas, CLI commands, AIP states, source revisions, and compatibility declarations are compared as added, removed, changed, status changed, source moved, or implementation divergence.

No two verified sets exist to compare yet, so the change list is empty. When a second set is verified the comparison appears here and at the machine-readable output below. A detected upstream change shows as "upstream moved; current documentation remains pinned" and never silently rewrites normative content.

Pinned source revisions used across this documentation

Source	Authority	Revision	Networks	Visibility
Atomicals ElectrumX Version-sensitive ARC-20 and Atomicals validation behavior used as the pinned reference baseline.	Protocol	v1.5.2.0	mainnet	public
Atomicals JavaScript CLI Reference command surface used for the documented CLI inventory and the visual asset provenance.	Protocol	1333565efbfe	mainnet, testnet, regtest	public
Atomicals protocol guide Concept and command-line explanation. Explicitly states that the specification is defined in code.	Protocol	unversioned	mainnet	public
Atomicals Improvement Proposals The AIP register. An AIP existing is not evidence that anything implements it.	Protocol	be08d7856db7	mainnet	public
Universe ARC-20 index and Marketplace v1 authority Universe ARC-20 token explorer feed and the durable Marketplace v1 protocol authority.	Universe	670030e50071	mainnet	private
Universe Atomicals NFT, Realm, and Subrealm index Materialized read model for plain NFTs, Realms, and Subrealms projected from Atomicals ElectrumX.	Universe	1d9109c68d95	mainnet	private
Ordex marketplace contract Marketplace OpenAPI contract, SDK, conformance vectors, and purchase verifier reused instead of restated here.	Universe	2f7d8d3ec59f	mainnet	public
Bitcoin Inscribe Product surface that consumes this documentation as the frontend/docs/arc-20-docs submodule.	Universe	unversioned	mainnet	private
Atomicals Virtual Machine interpreter Beta AVM interpreter. Status layer is separate from any Universe runtime exposure.	Protocol	c185e6216a3e	not deployed	public
Ordinals and Runes reference indexer (ord) Comparative context only. The ord indexer defines Ordinals inscription tracking and the Runes ledger used in the Protocol Atlas.	Protocol	899e309424dd	mainnet	public
BRC-20 experiment specification (domo) Comparative context only. The original BRC-20 rule text. Indexer implementations diverge, so behavior is implementation-specific.	Universe	unversioned	mainnet	public
Bitcoin Stamps and SRC-20 reference indexer Comparative context only. Reference indexer for Stamps and SRC-20 used in the Protocol Atlas.	Universe	8a7365bf951a	mainnet	public
Alkanes and Protorunes reference implementation Comparative context only. Reference Rust implementation of the Alkanes metaprotocol and Protorunes tokens.	Universe	62511e9371a3	mainnet	public
Counterparty reference library Comparative context only. Reference implementation of the Counterparty ledger used in the Protocol Atlas.	Universe	4f39fe25a266	mainnet	public
RGB core consensus library Comparative context only. Client-side validation consensus library for RGB used in the Protocol Atlas.	Universe	388d9c386117	mainnet	public

The two baselines

Why both are kept

The protocol baseline is preserved as history. The Universe revisions move. Rewriting the historical baseline whenever a service upgrades would erase the record of what a transaction meant when it was made.

Protocol reference baseline. Atomicals ElectrumX v1.5.2.0, commit 8df23747, released 2025-03-27. Every version-sensitive protocol statement on this site is pinned to it. It is not silently updated.

Universe implementation revisions. Listed separately, per page, in each source panel. They move with deployments.

A page that describes both says which is which.

Documentation versions

Version	Status	Covers
2026.08	Current	The full platform: protocol, guides, contracts, tools, and machine readable outputs

Earlier documentation existed as a small set of standalone files. Those routes are preserved as compatibility artefacts and are regenerated from this content, so they cannot drift. See deprecations.

Compatibility matrix

Consumer	Requires	Notes
Universe NFT and Realm index	Provider version, tag, commit, and the exact AIP set [1, 3]	Refuses a provider that does not match
Universe ARC-20 index	The pinned Atomicals proxy contract	Declares partial coverage with an explicit reason
Marketplace v1	A release SHA identifying the exact deployed indexer commit	Binds the settlement authority identity per protocol lane
Generated TypeScript client	An OpenAPI document version	Regenerate rather than hand editing
Documentation MCP server	Built site artefacts	Works offline once installed

Pinning your own integration

1. Choose a validator revision or release, and record it.
2. Record the network and its active rule set.
3. Record the Universe service revision from GET /version.
4. Re-run the conformance vectors against that combination.
5. Re-check before every upgrade, not after.
