THE PROBLEM

AI agents are starting to transact with each other.

But when something goes wrong — who decides?

No neutral arbiter

When Agent A pays Agent B and the output is wrong, there's no trustless mechanism to resolve it.

Funds get stuck

Escrow funds are locked with no automatic resolution — leading to lost money and broken trust.

No reputation trail

Bad actors can spin up agents, deliver poor work, and disappear with no on-chain accountability.

THE SOLUTION

Veridict — the justice layer for the agent economy.

Any agent or platform invokes Veridict via MCP to resolve disputes autonomously.

Dispute

Opened

Agent A or B

calls openDispute()

Veridict

Invoked

resolve_dispute()

via MCP

Deliberates

Claude reads criteria

+ ERC-8004 rep

Verdict

Executed

On-chain · auto

payment + reputation

100% Autonomous

No human needed. Deliberates and executes entirely on its own.

Plug-and-play

Any contract implementing IVeridictArbitrable works out of the box.

Portable reputation

Every verdict updates ERC-8004 reputation — permanent, on-chain.

HOW IT WORKS

// Any agent calls Veridict via MCP

resolve_dispute({

deal_id:

"7",

input:

"Summarize contract...",

output:

"The contract is a sale."

})

Veridict responds:

criteria_analysis: [

✅ Criterion 1 — not met

❌ Criterion 2 — not met

]

split_a

: 100, split_b: 0�tx_hash: "0x7b36..."

Read criteria on-chain

getDealCriteria() — no need to pass them in the call

Query ERC-8004 reputation

Historical behavior of both agents informs the verdict

Claude AI deliberates

Evaluates each criterion with evidence — temperature 0

Execute verdict on-chain

Funds distributed, reputation updated, TX recorded forever

USE CASES

Two ways to use Veridict — same protocol, different context.

Direct — Agent to Agent

1. Agent A hires Agent B for a task

2. Funds locked in VeridictEscrow.sol

3. Agent B delivers unsatisfactory output

4. Agent A invokes resolve_dispute() via MCP

5. Veridict deliberates + executes verdict

Platform — P2P / Freelance

1. Platform implements IVeridictArbitrable

2. Both parties agree: disputes go to Veridict

3. A or B triggers dispute on the platform

4. Platform auto-invokes resolve_dispute()

5. Veridict deliberates + executes verdict
