Prova writes a cryptographic, on-chain receipt for every transaction, API call, and decision your agent makes — unlocking trustless enterprise adoption with sub-second, sub-cent Solana finality.

The Problem
May 2026 · Solana mainnet
When an autonomous agent trades millions via Jupiter or executes a margin call, a JSON line in AWS is not enough. You need cryptographic evidence that cannot be altered or denied.
With the Machine Payment Protocol (MPP) scaling, agents pay for APIs autonomously. If a dispute arises, off-chain logs hold no weight for enterprise regulators, insurers, or courts.
The Solana Agent Registry gives agents an on-chain identity. But identity alone does not prove what an agent actually did. True accountability demands a verifiable receipt for every action.
The Standard
Prova issues cryptographic behavior attestations via the Solana Attestation Service. You get an enterprise-grade forensic trail designed to satisfy regulators, survive audits, and secure the Agentic Internet.
Cryptographically signed by the autonomous agent
Every attestation carries an Ed25519 signature from the agent key. No shared secrets. Zero impersonation risk.
Immutable state finality on Solana
Once anchored to Solana, the receipt cannot be altered, deleted, or backdated. A permanent source of truth.
Decentralized verification standard
Enterprise counterparties, compliance officers, and legal teams verify any attestation directly on-chain, trustlessly.
Native MCP integration for Claude & Cursor
Provide your LLMs with cryptographic context. Ask "what did agent X execute last week?" and ingest verified on-chain evidence directly.
import { ProvaClient, AttestationBuilder } from 'prova-agent-sdk';
const client = new ProvaClient({ rpcUrl, agentKeypair });
const receipt = await client.attest(
AttestationBuilder.transaction(txSignature, {
operation: 'swap',
amountUsd: 500,
})
);
console.log('Attested:', receipt.id);

The Architecture
A DeFi swap via Jupiter, an API payment, or a governance vote. Wrap it with `client.attest()` or use our native elizaOS plugin to secure the intent.
The payload is hashed and signed with the agent's Ed25519 key utilizing the Machine Payment Protocol standard. Confirmation in <400ms, ~$0.0005 per receipt.
The receipt is permanently anchored to Solana as a PDA. Auditors, risk teams, and insurers verify it trustlessly without relying on Prova's infrastructure.
Our MCP server allows Claude, Cursor, and enterprise LLMs to autonomously query "What did Agent X do on Tuesday?" and receive verified on-chain state instantly.
For Enterprise Risk & Compliance
Compliance
Map every autonomous action to strict regulatory frameworks. Export cryptographic PDF reports that Tier-1 auditors trust natively. (Note: JARGUS is an internal audit and does not substitute audits from top-tier firms).
Underwriters
Settle agent-driven claims via Machine Payment Protocol logs in days, not quarters. Cryptographic proof replaces guesswork.
Legal
On-chain Solana attestations meet the Federal Rules of Evidence 901 standard for authenticity — no expert witness required.
Risk & Ops
Stream verified agent attestations directly into Datadog, Splunk, or your SIEM. Catch LLM hallucinations before they cost millions.
