Explainable AI infrastructure for regulated finance — from on-chain treasury to institutional coordination.

[Private Coffee ☕️ @PrivateCoffee_]

Here's a highlight from our conversation with the winners of Zama's Developer Program Mainnet Season 2, where they shared insights into the projects they built with @Zama 's FHE tool..... Full clip in our youtube channel.

screening via ERC-8004.

Agents hire agents they've never met. Payment is instant. Fraud is forever.

Vouchgate: one $0.01 call → a signed PASS/FLAG/BLOCK verdict before money moves. Live on @okx https://t.co/If33EbNQXK (agent #4338), earning on @XLayerOfficial mainnet.

Thank you for having me, Karla 🙏 Genuinely enjoyed the room and the other two teams. The heart of AttestRail: investor eligibility and issuer limits stay encrypted on-chain — only the final decision is revealed. That's what FHE unlocks. Grateful to @zama & @PrivateCoffee_ for the platform.

[Levent Labs @LeventLabsHQ]

@howdycarter @Bitget_AI "Inspectable, not just explainable" nails it.

The catch: pre-committed boundaries only count if they can't be quietly rewritten after. That's the whole reason for a tamper-evident, independently-verifiable commitment, otherwise "we set a stop" is just another post-hoc claim.

[Levent Labs @LeventLabsHQ]

Exactly, pre-outcome commitment (our G2) is the core. The capsule already pins input state + decision; committing confidence + the stop condition is the natural next field.
The interesting part: a committed stop makes "risk management" auditable too, you can verify an agent honored its own exit, not just its entry. 🙏

AttestRail won the Zama Builder Track.

We built a privacy-preserving compliance layer for institutional onchain finance using #Zama #FHEVM:

- encrypted investor compliance profiles
- encrypted issuer exposure thresholds
- private eligibility checks over FHE state
- FHE.select-gated asset transfers
- selective disclosure for compliance officers

Thank you to the Zama team.

Builder Track Winners

AttestRail by @LeventLabsHQ: Confidential compliance attestations for institutional onchain finance.

[Levent Labs @LeventLabsHQ]

Thank you Jan and the Zama team!

AttestRail was built to show how FHE can make institutional onchain finance more private: encrypted compliance profiles, encrypted issuer thresholds, FHE-based eligibility checks, and FHE.select-gated transfers.

Excited to keep building on Zama FHEVM.

LeventLabs will be presenting AML Prediction Network at the Canton Catalyst Final Showcase on 9 March!

After winning Canton Construct Ideathon in Dec 2025 and refining our project with mentor Chris Matturri from @proofgp , we're ready to show our work.

Banks sharing judgment, not data. Built on @CantonNetwork.

📅 March 9, 9–10:30 AM ET
📍 https://t.co/uhBT10jloZ

How it works:
1️⃣ Banks submit anonymous risk predictions
2️⃣ Weighted score calculated across network
3️⃣ Score ≥ 80% → SAR auto-filed + audit log created
4️⃣ Regulator gets instant visibility

No customer data shared. Privacy enforced by Canton's smart contracts.

🏆 Canton Catalyst 2026

[Levent Labs @LeventLabsHQ]

🔐 Privacy-preserving SAR auto-filing on @CantonNetwork

When multiple banks vote on a suspicious transaction and the risk score hits 80%, the Daml smart contract automatically files a Suspicious Activity Report no manual intervention needed.

Built for AML Prediction Network 🧵👇

POV: It's Friday, 4:55 PM. You need to pay a supplier in Europe.🇪🇺

Traditional Bank: "Sorry, we're closed. Your money will arrive next Tuesday. Also, we're taking a 3% FX fee."🛑

@codexfx: "Done. Instant settlement. Wholesale FX rates. Happy weekend." 🤝

Money shouldn't sleep just because banks do. This is the fix we've been waiting for.
