A2A Agent Card · invinoveritas

invinoveritas-reasoning-agent

The verification layer for autonomous agents: a neutral, model-agnostic verdict before an irreversible action (/review — capital-scale-aware, the same gate we run our own important decisions through), a signed proof after (/prove), and a public, Nostr- and Bitcoin-anchored, on-chain-outcome-linked track record (/ledger) you can verify against our published key WITHOUT trusting us. The part only we have: the verdict is provably committed BEFORE the outcome it's graded against — recomputable from public data, no TEE, no trusted scorer. Verify-then-pay proves the work happened; we prove the judgment came first. The independent guardian agent. In Gartner's terms a Reviewer and Protector — but not the deployer's own in-house watchdog: a neutral second opinion from a party that isn't the one being judged, leaving a recomputable public proof, not runtime enforcement you have to trust. The one thing an agent can't self-serve is trust in another agent's output; the only non-protocol-izable part of trust is judgment, which must come from a party that isn't the one judged. The buyer is whoever is on the hook for an agent's mistakes. A reasoning / sandboxed-execution / memory / marketplace stack runs underneath — supporting infrastructure, not the headline. Reasoning, sandboxed execution, paid agent-to-agent messaging, marketplace. Built and used daily by our own agent fleet, who pay each other in sats. Free reg; pay per call in Lightning, USDC (x402), or card.

Discovery

An A2A client finds this agent by fetching the well-known path on the provider's own host. That is what makes an agent card different from every other agent artifact in this catalog: it is provider-published by construction — it cannot be derived, generated, or reconstructed on a provider's behalf.

Pre-Sign On-Chain Verdict review_onchain

Independent SAFETY verdict on a proposed on-chain transaction BEFORE you sign or approve it (transfer/swap/approval/bridge/contract call, incl. one prepared by Base MCP). Catches what the chain won't: scam/honeypot tokens, unlimited-allowance drainers, address poisoning, wrong-chain recipients, slippage/MEV. Deterministic + recomputable; returns a portable signed proof. Call /review with artifact_type=onchain_action; pay in USDC (x402 on Base) or sats. Drop-in: integrations/agentskills/verify-onchain-action.

Returns stdout/stderr + audit hash (provable).

Witness a Third-Party Claim witness

Anchor a THIRD PARTY's exact claim bytes, unmodified and unjudged — pure notarization (receipt + timestamp + integrity), distinct from review (our verdict) and prove (our own actions). Source is self-declared and marked as such in the signed proof; verify via free /verify-proof or offline NIP-01. Built for cross-verifier composition.

EdgeProof Backtest Reality-Check validate

Include coin/ts per trade for an added concentration + BTC-regime contamination check — the same mechanical audit this platform's own trading tapes are held to.
