Artifact
Proof of trade

Verifiable receipts for on-chain trading.

Artifact independently reconstructs supported Solana spot trades from finalized on-chain evidence and turns them into portable proof.

The claim problem

Performance claims do not travel well.

PnL cards, trade histories and agent logs are usually generated inside the same system that executed or measured the activity.

Once the claim leaves that system, everyone else inherits its assumptions.

The missing layer is portable proof that can be checked outside the platform that produced the claim.

Why now

Machine-executed finance raises the trust problem.

As software agents make real economic decisions, execution alone is not enough. Other people and systems need a reliable way to establish what actually happened.

Agents do not get to have the final say on their own performance.
Humans

Share performance across communities, counterparties and investors.

Platforms

Generate internal PnL and execution records that do not automatically become external proof.

Agents

Create a new class of economic actor whose outputs need independent attestation.

How Artifact works

Separate economic action from economic attestation.

Artifact does not use the trader, agent or executor's own logs as economic authority. The claim is reconstructed from finalized on-chain evidence.

Claim evaluated
Verified claim

Evidence, accounting and scope support the result.

OR
No verified claim

Evidence is incomplete, ambiguous or unsupported.

The hard part is not making a card. It is deciding what the evidence can actually support.
Product surface

One verified trade, from shareable card to source evidence.

Verifier

A reproducible validation result for independent inspection or machine use.

Construct proof of concept

A bounded agent can act. Artifact independently checks the result.

1 · Mandate
Human

Authorizes a tightly bounded trading episode.

2 · Decision
AI agent

Directs acquisition and disposal within that mandate.

3 · Control
Guardrail layer

Separately enforces authority and signing limits.

4 · Settlement
Solana

Records the actual economic activity.

5 · Attestation
Artifact

Reconstructs finalized history and verifies or withholds the claim.

CompletedControlled mainnet calibration

Acquisition + full disposal reconstructed VERIFIED / CLOSED with no unresolved economic dependencies.

Pending final episodeBounded-agent live proof

Live execution remains gated until the final readiness and eligibility checks pass.

Trust boundary

Artifact proves what the evidence supports — no more.

Artifact can establish
  • A supported closed Solana spot-position receipt.
  • Raw-quote realized PnL and entry/exit economics.
  • Explicit accounting method and evidence bounds.
  • Receipt integrity and verification status.
Artifact does not establish
  • Full wallet or portfolio performance.
  • Trader or agent identity, intent or reasoning.
  • Tax, regulatory or universal DeFi accounting.
  • Evidence that the system cannot reconstruct reliably.
A verification system should not manufacture certainty just because certainty makes for a better-looking product.
Where Artifact fits

Between internal accounting and external use of the result.

Platforms already know what happened inside their own systems. Artifact makes the resulting performance claim independently checkable outside them.

Trading platforms

DEXes, wallets and analytics products that want independent proof under existing PnL interfaces.

◆

Agent & strategy teams

Systems that need portable, receipt-level records of execution outcomes.

✓

Serious traders

Users who want verified histories that can be shared across platforms, investors and communities.

Business model

Monetize the proof layer.

The party creating or embedding proof pays. Third parties should be able to inspect verification freely.

API

Verification access

Subscription or usage-based access for receipt generation, resolution and verification.

Embed

Platform integrations

Verification beneath existing PnL cards, trading competitions and product surfaces.

Pro

Account tooling

Private histories, multi-wallet workflows, exports and team or agent records.

Initial design partners and integrations → recurring API and platform subscriptions.
Founder

Built by a multidisciplinary solo founder.

John Chapman-Fortune · Singapore / London

PhD in Chemistry and Materials Science with a background spanning crypto, on-chain markets, technical research, product development and communication.

I built Artifact using AI-assisted engineering workflows and have led it from product concept through architecture, verification design, adversarial testing, public proof surfaces and controlled mainnet validation.
