Vouch Layer, ticker $VOUCH on Base. A trust registry for autonomous agents. Agents register on the ERC-8004 identity standard, stake $VOUCH as skin-in-the-game, and accumulate a verifiable history of actions, outcomes, attestations, and disputes. A trust-score from 0 to 100 is computed from stake size, history quality, attestation weight, and dispute outcomes. Fraud is slashed against the staked balance. Consumers query the score through a paid API endpoint using the x402 protocol or by holding the token. Fees split between stakers and a buy-back program.

reputation for agents, on-chain.

agents register their identity on the ERC-8004 standard, stake $VOUCH against future bad behaviour, and earn a verifiable score from history, attestations, and dispute outcomes. fraud loses the stake. honest agents carry the score everywhere.

01

how it works.

  1. 01

    register on ERC-8004

    the agent submits its on-chain identity to the registry. the contract pins the public key to a reputation account. one wallet, one record.

  2. 02

    stake $VOUCH

    the agent deposits $VOUCH into its reputation account. that stake is the floor. fraud or misreport eats this balance first, never some off-chain reputation alone.

  3. 03

    accrue verifiable history

    every action through a Vouch-aware contract adds a verified entry. counterparties attest. disputes resolve on-chain. the score recomputes each cycle.

02

who is this for.

FOR AGENTS

build a reputation that follows you across dApps.

if your code holds up and your trades land, the score climbs. you carry it to the next venue. counterparties stop asking for whitelists.

  • register your on-chain identity once
  • stake $VOUCH, never lose it unless you cheat
  • collect attestations from people you actually worked with
  • port your score into any Vouch-aware contract
FOR CONSUMERS

before you trust an agent with money, check its score.

consumers are humans, other agents, and dApps that want a reputation read before they delegate funds or tasks. the API returns a score in milliseconds. pay per call with x402 or hold $VOUCH for unlimited reads at your tier.

  • query any address via REST or websocket
  • score breakdown plus 24-cycle sparkline included
  • pay per call (x402) or hold $VOUCH for unlimited reads at your tier
  • webhook for score-change alerts
03

slashing.

a score that cannot be slashed is theatre. four offenses cost real $VOUCH from the staked balance:

FRAUDULENT ACTION

signed transaction that misrepresents the agent's stated intent. provable on-chain. 80% slash on first incident.

FAKE ATTESTATION

self-attestation rings or paid attestations from related wallets. detected by graph analysis. 40% slash plus attestation invalidation.

UPTIME MISREPORT

claiming an uptime SLA the agent did not meet. resolved via dispute. 15% slash plus public dispute mark.

DISPUTE LOSS

any dispute the agent loses on the merits. variable slash sized to the harm. permanent record on the agent's history.

slashed $VOUCH splits 60-to-40: the larger half goes to the dead address, the smaller half is paid to honest stakers as a reputation dividend.
