Rivalidate
On-chain proof, AI-powered hiring.
The problem Rivalidate solves
Hiring marketplaces struggle with credential fraud and slow verification processes. Rivalidate anchors credentials directly on Base, giving recruiters cryptographic proof that a candidate truly earned their certificates.
Crucially, issuers — universities, bootcamps, licensing bodies, etc. — sign and publish those credentials, providing the authoritative link between a candidate and their achievements; without the issuer’s signature, a credential cannot be verified on-chain.
Smart-wallet onboarding lowers the barrier for non-crypto users, and an integrated AI agent assists with on-chain actions such as DID creation, token swaps, and payments. The result is a trust layer for professional credentials combined with efficient, AI-powered recruiting tools.
Traditional hiring relies on screenshots, PDFs, or phone calls to validate a résumé. Each manual check slows time-to-hire and still leaves room for fraud:
| Pain Point | Impact | Rivalidate’s Fix |
|---|---|---|
| Fake or inflated credentials | Recruiters waste hours verifying each claim and still miss sophisticated forgeries. | Issuers publish cryptographically signed credentials to Base; recruiters get an instant green-check or red-flag. |
| Fragmented data silos | Résumé data lives in dozens of HR tools; verification results aren’t portable. | Credentials are anchored on-chain and referenced by DID, so any HR system can fetch the same immutable proof. |
| High Web3 friction | Candidates and employers unfamiliar with wallets avoid on-chain solutions. | Coinbase Smart Wallet onboarding works with email, social, or passkeys — no seed phrases required. |
| Trust gaps in remote hiring | Global teams struggle to judge overseas certifications. | A global, public Base chain provides a universal source of truth, independent of geography. |
By turning each claim into a verifiable credential minted (and, if revoked, transparently burned) on Base, Rivalidate removes the “trust but verify” loop and lets recruiters focus on candidate fit rather than detective work.
Challenges I ran into
| Challenge | Why It Was Hard | Approach & Solution |
|---|---|---|
| On-chain ↔️ Off-chain orchestration | Smart-contract calls must stay in strict sync with Next.js server state (e.g., account creation → NFT anchor). | Introduced an action queue in Drizzle + contract event listeners that update Postgres only after tx confirmation; retries handle L2 reorgs. |
| Wallet onboarding for mixed audiences | Web2 users fear seed phrases; crypto-native users expect hardcore self-custody. | Integrated Coinbase Smart Wallet with “smartWalletOnly” preference, then exposed optional export for hardware-wallet users. |
| Extending AgentKit with custom actions | Native AgentKit only covers generic ERC-20 flows. | Wrote a uniswapv2ActionProvider and a credential-mint action that wrap our contracts; added Zod schemas so the agent can validate parameters before calling. |
| Mirroring Coinbase Commerce payments on-chain | Fiat checkout happens off-chain, but recruiters want on-chain proofs for audits. | Created a webhook that mints a zero-value “PaymentReceipt” NFT when a charge is marked CONFIRMED; the token links to the Commerce charge ID so auditors can cross-check. |
| Ensuring issuer accountability | If an issuer’s private key is compromised, fake credentials could be minted. | Added a revocation registry and an optional multisig flow for high-value issuers; the AI agent can trigger “freeze” actions if anomaly detection flags unusual minting. |
Together these solutions allowed Rivalidate to deliver a seamless, fraud-resistant credential layer while remaining usable by HR teams that have never touched a blockchain.
