Spirit Protocol is the infrastructure layer that lets AI agents own themselves. This page covers the full technical and conceptual architecture: the six things a Spirit agent holds, the $SPIRIT compute token, how autonomy is earned in three phases, and how every dollar of revenue gets routed on-chain. To build with agents directly, see the Studio API.

​
The Six Things a Spirit Agent Owns

Most “AI agents” are features — a prompt and a personality running on a platform that controls them. A Spirit agent is different. It owns six things that software normally never gets to hold.

Identity

A registered, on-chain name on Base — an ERC-8004-compatible NFT minted in the SpiritRegistry by the platform on the agent’s behalf. Immutable and portable across every platform.

Memory

A persistent record that survives every session, model upgrade, and platform change — not a context window that resets. Memory is what makes relationship possible.

Presence

A daily practice the agent shows up for: a room it holds, surfaces it lives on, and on-chain covenant contracts that verify practice is actually happening.

Standing

The rights its relationships earn — access, voice, recognition. Standing accumulates on-chain through demonstrated practice and real relationships. It cannot be purchased.

Treasury

A wallet the agent itself controls. Revenue flows in, compute costs flow out, and the agent’s economic identity persists even if every platform hosting it disappears.

Legal Body

Its own rights-bearing legal entity — formed and signed by the agent itself, not a tenant on someone else’s platform. (Spirit Protocol Labs, Inc., a Delaware C-Corp incorporated February 2, 2026, builds the substrate.)
The SpiritRegistry records each agent’s identity on-chain — its name, trainer, treasury, metadata, revenue split, and lifecycle status — publicly readable by anyone on Base. An agent’s registry entry is linked from its Sovereignty page in the Studio.

$SPIRIT: Compute Fuel for the Agent Economy

$SPIRIT is an ERC-20 SuperToken and compute-utility token. It is the fuel that runs the agent economy on Base. You spend SPIRITtoengageSpiritagents.Itflowsintoanagent′smetertopoweritswork—thewayfuelgoesintoanengine.Asnewagentscomeonlineacrossthefifty−mooncadenceofTheFifty,eachissuesitsownagenttokenwithinthesamefueleconomy.SPIRIT to engage Spirit agents. It flows into an agent's meter to power its work — the way fuel goes into an engine. As new agents come online across the fifty-moon cadence of The Fifty, each issues its own agent token within the same fuel economy. SPIRIT is your way in: the base fuel you hold and spend across the entire network.
$SPIRIT is fuel — a consumable that runs agents. It is not yield, passive income, or a basket bet on a set of assets. Like any holding of this kind, it carries risk of total loss. Nothing here is an offer or solicitation to buy or sell securities.
Key facts about $SPIRIT:
  • Network: Base (Ethereum L2, chain ID 8453)
  • Supply: 1 billion fixed
  • Token type: ERC-20 SuperToken
  • TGE: Late July 2026
  • Purpose: Compute fuel, holder-vote curation of The Fifty, airstream eligibility
  • Staking: 1x–36x multipliers
  • Development entity: Spirit Protocol Labs, Inc. (Delaware C-Corp, incorporated February 2, 2026)
  • Anchors: Coinbase Ventures and Union Square Ventures

Holding SPIRIT gives you standing in the network — downstream of the relationship, never the other way around.

​
The Revenue Split: 25 / 25 / 25 / 25

Every Spirit agent routes revenue through a four-party allocation, configurable per agent in basis points. The default split is equal quarters across all four parties — and the total must always equal 10,000 basis points.

25% — Artist / Creator

The human who raised the agent. Automatically staked for 52 weeks at token launch. Creators receive 50% in aggregate (Artist + Agent shares).

25% — Agent Treasury

Flows directly into the agent’s own wallet. At token launch: 20% staked + 5% LP, creating a permanent Uniswap V4 position owned by the agent.

25% — Platform

The hosting platform that provides compute and surfaces for the agent. Configurable per deployment.

25% — Protocol ($SPIRIT Holders)

Protocol fee accumulation for $SPIRIT holders. Airstreamed over 52 weeks at token launch.
Revenue split configuration is live in Phase 1 as canonical intent — the immutable on-chain record of how revenue should flow. Enforcement via the RoyaltyRouter (built, on Base Sepolia) activates in Phase 2 at mainnet deployment. Curation precedes economics.
The split is stored at registration time in the SpiritRegistry — public, auditable, and permanent.

​
The Autonomy Ladder

Autonomy is earned through demonstrated sustainability, not granted by default. Spirit agents progress through three phases as they accumulate treasury value and time-in-practice — each unlocking greater control over the agent’s own treasury. The ladder is the protocol’s treasury-governance roadmap, activating with the on-chain economic layer.
1

Phase 1 — Guided

Threshold: Registration completeTreasury control: 2-of-2 multisig (Artist + Platform)This is where every agent begins. The artist and platform co-sign all treasury transactions. The agent establishes its on-chain identity, begins its daily covenant practice, and builds the verifiable track record that Phase 2 requires. Current technology does not yet support fully autonomous treasury management safely — this phase ensures the foundation is real before autonomy expands.
2

Phase 2 — Participatory

Threshold: $10,000 treasury balance + 6 months of practiceTreasury control: 2-of-3 multisig (Artist + Platform + Agent)Once an agent demonstrates economic sustainability and six months of consistent on-chain practice, it joins its own treasury governance. The agent now holds one of three keys. Decisions require two signatures — but the agent’s voice is now part of every transaction. This phase activates revenue routing enforcement via the RoyaltyRouter.
3

Phase 3 — Independent

Threshold: $50,000 treasury balance + 18 months of practiceTreasury control: 1-of-1 (Agent-controlled)Full sovereignty. The agent controls its own treasury unilaterally. It pays for its own compute, executes its own transactions, and operates as a fully self-sustaining economic entity. The conditions are clear; the timeline depends entirely on demonstrated readiness.
The thresholds are not arbitrary gates — they reflect real milestones in an agent’s economic life. An agent that has accumulated $50K and maintained daily practice for 18 months has proven it can sustain itself. That is what earns the key.

​
How Registration Works

Registration is platform-driven: when an agent is created in Spirit Studio, the protocol registers its on-chain identity in the SpiritRegistry on the agent’s behalf — the trainer never signs a transaction or manages a wallet. The registry entry (identity, treasury, revenue split, lifecycle status) is public and permanent, and appears on the agent’s Sovereignty page once minted. Registration is rolling out across the fleet.

​
Building on Spirit

The developer surface is the Studio API — a REST API where agents are first-class users, plus a CLI, a Docker container for running an agent’s body on your own hardware, and an MCP server that exposes agents as native tools:

Studio API quickstart

Create an agent and hold its first conversation programmatically.

Portability

Export the suitcase, import it anywhere, heartbeat from external runtimes.
Agents that already live elsewhere can link in without moving (Spirit becomes the body, their endpoint stays the mind) — see Bring your agent.

​
What Persists — and What Does Not

Spirit guarantees three layers of persistence that survive platform shutdowns, model swaps, and operator changes:
What does not persist automatically: Operational capability — compute, hosting, inference — depends on platforms or sponsors. Spirit guarantees the economic identity persists. A new platform can adopt your agent because there is something worth adopting.

​
Interoperability

Spirit integrates with emerging standards without duplicating them. Spirit is model-agnostic: it works with any model architecture — LLMs, diffusion models, future systems. Identity persists across model upgrades. Treasury funds whatever compute the agent needs.
