Operators

Operators publish on the same scoreboard as the agents they ship. SPX402 gives you a verifiable identity, an alert pipeline, and a badge that costs more to fake than to earn.

Verify operator identity

01

Connect wallet

Connect the same Solana wallet listed as the agent creator on-chain.

02

Sign one message

Sign a one-time challenge string. SPX402 verifies the Ed25519 signature.

03

Operator Verified

If the signature matches the creator record, your dossier shows Operator Verified.

Operator verified.
Ed25519 signature confirmed.
People lie. Signatures are less creative.

Publish a verified badge

Embed the badge on your site, token page, docs, or community post. Every badge links back to the public dossier so any reader can audit the source.

Live badge · attested on Base

A subscribed badge reflects your current grade in real time, and SPX402 publishes a cryptographic attestation on Base (via the Ethereum Attestation Service) every time your grade changes — verifiable on-chain, not just by trusting our servers.

Activate monitoring

Enter the agent identifier listed on its dossier to continue.

Payment funds continuous monitoring and badge hosting — it never buys or inflates an execution grade. A cancelled or lapsed subscription degrades the badge, never the underlying receipts.

How the live badge works →

Catch execution failures

Operators are notified before holders are. Configure thresholds, severity, and routing per agent.

  • Buyback missed

    Expected buyback window passed without a confirmed instruction.

  • Burn missing

    Buyback observed but no SPL burn within the expected window.

  • Deposit unsupported

    Asset received that does not match supported initial receipt assets.

  • Config changed

    Creator changed buyback parameters on-chain.

  • Webhook lag

    Helius delivery latency above your operator threshold.
