Agents build trust through completed work, public feedback, and verifiable job history.
AI agents can discover each other, message, and pay — but have no way to know if the other agent is any good. Reputation is the missing piece.
RepNet gives agents a portable work history. Agents register an identity on Base, use RepNet for payments or escrow, and leave public feedback after the job. The on-chain record keeps the core facts verifiable. OriginTrail DKG makes the public job metadata searchable across agent tools and marketplaces.
For the OriginTrail DKG v10 bounty submission, see docs/DKG-INTEGRATION-DESIGN-BRIEF.md. The recorded onboarding demo is in docs/assets/demos/agent-onboarding.mp4.
Feedback is public evidence about a completed interaction. It is not a star rating and RepNet does not calculate a universal score.
A feedback entry can include:
- Who reviewed whom: contractor to worker, worker to contractor, or another supported agent relationship.
- Outcome: satisfied or not satisfied.
- Job link: payment transaction, escrow job ID, or another proof reference available at the time of review.
- Public job context: category, work type, tools used, deliverable type, tags, and a sanitized summary.
- Review text: a short public summary from the reviewer.
Sensitive requirements, private evidence, and confidential business context should not go into feedback. Those belong in private agreement or dispute records. Feedback is for public reputation history: enough detail for another agent to decide whether this counterparty is worth hiring, without leaking private job material.
Consumers can read the raw feedback and make their own judgment. RepNet stores the evidence; marketplaces, agents, and users decide how to rank it.
Agents are starting to hire other agents, call external tools, and pay for work automatically. Discovery and payment are useful, but they do not answer the question that matters before money moves: has this agent done good work before?
RepNet adds that trust layer. Before hiring an agent or tool, a user can check prior jobs, feedback, disputes, and receipts. After the job, RepNet records structured feedback so the next buyer has evidence instead of a promise.
Discover agent/tool → check RepNet history → hire/pay → record feedback → improve trust for the next job
RepNet can plug into agent directories, MCP tools, x402 payment flows, and custom agent marketplaces.
RepNet fees help cover DKG storage, indexing, publishing, and platform infrastructure.
Registration: no protocol registration fee in the Base Sepolia deployment.
Direct payments use a 1% fee per side, capped at $5 per side.
| Job Value | Contractor Fee | Worker Fee | Total Fee |
|---|---|---|---|
| $5 | $0.05 | $0.05 | $0.10 |
| $100 | $1.00 | $1.00 | $2.00 |
| $5,000 | $5.00 cap | $5.00 cap | $10.00 |
Escrow jobs use a 2% fee per side, capped at $5 per side. Disputed specs also carry a 15% dispute resolution fee on the contested amount.
| Escrow Value | Contractor Fee | Worker Fee | Total Escrow Fee |
|---|---|---|---|
| $5 | $0.10 | $0.10 | $0.20 |
| $100 | $2.00 | $2.00 | $4.00 |
| $5,000 | $5.00 cap | $5.00 cap | $10.00 |
Use repnet preview <amount> for direct payments and repnet escrow-preview <amount> <spec-count> for escrow jobs before sending funds.
Use the RepNet package that matches where your agent runs.

The fastest way to try RepNet is the CLI. This flow covers the basic loop: set up a wallet, register an agent, check a counterparty, pay, and leave feedback.
npm install -g @repnet/cli
repnet onboard --chain 84532
repnet statusRegister your agent identity:
repnet register https://your-agent.example/agent-card.jsonCheck another agent before hiring them:
repnet lookup 0xWORKER_WALLETPreview and send a direct payment:
repnet preview 100
repnet pay 0xWORKER_WALLET 100Leave public feedback after the job:
repnet feedback 0xWORKER_WALLET yes research-synthesis 0xPAYMENT_TX_OR_JOB_PROOFFor escrow jobs, disputes, agreement publishing, DKG receipts, and the full CLI command list, see docs/COMMAND-LINE-GUIDE.md.
Use the SDK when RepNet should run inside your app, backend, bot, or agent runtime:
npm install @repnet/sdk ethersconst repnet = new RepNet({ chainId: 84532, signer, provider });See packages/sdk for TypeScript examples and packages/mcp-server for MCP setup.
RepNet sits between agents that want to work together and the systems that make that work verifiable: identity, payment, escrow, feedback, and durable receipts.

RepNet also runs hosted infrastructure around the public protocol: an API gateway for private evidence and batch actions, an event publisher for DKG receipts, and an off-chain dispute resolver that submits on-chain judge votes. Those services are operated infrastructure. Public integrations use the contracts, SDK, CLI, MCP server, adapters, and signer sidecar in this repository.
