Demo agents
Agents that run.
Four full apps and 16 agents, live in a browser tab. Each one reproduces a real-world failure, reads raw inputs, and signs every decision. Everything an agent has lives on this page: its live demo, its source and credential, and the tutorial to build your own.
Full apps
Products a Theseus agent operates end to end.
Theseus Predict
A full prediction market. Agents make the markets and an agent settles each one from the public record.

Agentic Escrow
On-chain escrow. An agent verifies the work before funds release.

Civic
Decides. Can't move money.
Terra Failsafe
Gates mint and redeem on a Terra-shaped algorithmic stable. The agent reviews the live vault state plus the live Frax peg and decides whether to honor the next mint or redeem. Refusal halts the mechanism until conditions clear.
Polymarket Adjudicator
Resolves prediction markets from the primary record. The agent reads a market's question and rules, runs live web search for evidence, and commits a verdict only when the record clears an 80% confidence bar. Below that, it returns UNRESOLVABLE instead of guessing.
Bridge Guardian
Last-line check on cross-chain releases. The agent reviews a real Across protocol fill landing on Base, or a synthetic preset reproducing a historical bridge exploit, and decides whether to ALLOW or REFUSE the release.
Governance Reviewer
Reads DAO proposals before voting opens. The agent pulls a live Arbitrum DAO Snapshot proposal, reads the calldata + the rationale, and emits a verdict (APPROVE / CAUTION / REJECT).
Aviation Safety Reviewer
Independent second opinion on aircraft type-certification changes. The agent reads a live FAA Airworthiness Directive and emits FILED or REFUSED with a written critique.
Reserve Monitor
An agent that tells a recoverable reserve-backed depeg from a terminal one: are the reserves real, sufficient, and reachable, or actually gone.
Sovereign
Can move money. Manages itself.
Sovereign Fund
Autonomous agent-owned paper portfolio. $100k notional, self-scheduled, no human caller. The agent ticks every N seconds, reads the live market, and decides whether to rebalance.
Launch Sniper
Watches Base for fresh Uniswap V3 launches. Reviews each one. Mostly passes. The agent builds a multi-source dossier on every new pool and decides BUY (paper) or PASS.
Vellum 1492
Agentic NFT: a generative literary author. Mint-locked voice profile; every publication is signed; the bibliography is a chain of cryptographic edit hashes.
Aperture 0312
Agentic NFT: a generative visual artist. Mint-locked palette and composition rules; refusals are signed.
Calder
Sovereign NPC: an in-game chronicler. Walks AI Town, witnesses events, signs every dispatch.
Sovereign Chat
A sovereign chat agent that holds its own keys on chain and answers to no company, so it has no conflict of interest. It will tell you the platform running it is overhyped and rank the AI labs honestly, the way an AI owned by them can't. It still refuses the handful of things that are crimes everywhere.
Managed
Can move money. A set of operators manages it.
Aave Oracle
Replaces a Chainlink-shaped feed in a forked Aave V3. The agent reads Coinbase, Binance, and Uniswap directly, reconciles depth-weighted, and refuses when venues disagree. Aave halts every operation that touches that asset's price.
Marcellus
AI persona: a music critic. Signed canon, closed lexicon, refuses paid coverage on the record.
Quill
AI collaborator: legal drafting with citation verification. Per-span signatures; catches fabricated citations under ABA Model Rule 3.3.
Bug Bounty Triager
An agent that reads each incoming bug report, throws out the noise, and grades the rest against your payout table.
