The brief: ship dApps on Nox, iExec's confidential smart contract layer using Confidential Tokens to bring real privacy to DeFi & RWA.

Ever wonder how an on-chain request becomes a confidential off-chain computation in @iEx_ec Nox?

Meet the Ingestor,  the mailroom clerk of the protocol.

It watches the chain, reads NoxCompute events, sorts them by transaction, and drops each bundle onto a reliable conveyor belt (NATS JetStream) for the Runner to pick up.

Runs inside Intel TDX. Resumes exactly where it left off after a restart. No gaps, no double-processing.

[iExec Developer @iExecDev]

The "Use AI to build on NOX" guide shows you step-by-step how to unlock artificial intelligence capabilities right within the protocol.

Expect best practices, code examples, and a seamless setup.

Ask Claude to write you a confidential token. Watch it ship.

Dev tip: on Nox, your smart contract NEVER sees plaintext values.

It works with handles, which are references to ciphertexts. The encrypted text never appears in the clear on-chain.

You write standard Solidity. Confidentiality is handled under the hood by attested TEEs.

Cleanest read on the 2026 confidentiality thesis

Not hiding everything. Selective disclosure: holder decides who reads what, revocable, enforced onchain.

Great breakdown @Altcoin_daddy

Privacy isn't a feature you bolt on at the end, it's an architecture choice

That's exactly what Nox is built for, ready when you are, devs

[ALTCOIN D/G\DDY 🇹🇹🇳🇬 {A.D}𓃵 @Altcoin_daddy]

What makes @iEx_ec Nox different from normal Web3 tools?

Most Web3 tools help developers build on-chain apps.They help with smart contracts, wallets, tokens, transactions, frontend integrations, and all the usual parts of building in Web3 and that is useful. But one thing most of these tools do not really solve is privacy.

In a normal Web3 app, a lot of important data is public by default.
Wallet activity can be tracked.
Balances can be seen.
Payments can be followed.
Positions in DeFi can be monitored.

That is one of the tradeoffs of building on public blockchains. And this is where Nox Protocol stands out. Nox is different because it is not just helping developers build on-chain but It is helping developers build apps that can use sensitive data without exposing that data publicly on-chain.

That is a very important difference. So instead of saying everything must be visible because it is Web3, Nox introduces a different idea Some parts of an app can stay private while the app still works on-chain. That is why I think of Nox as a privacy layer for Web3.

It gives developers a way to start building things like:
private balances
confidential DeFi apps
privacy-friendly vaults
selective disclosure systems
RWA apps with protected sensitive data
What makes this interesting is that privacy is not treated like an extra feature added later.

It becomes part of how the app is designed from the start And I think that is where Web3 is heading.Because if blockchain wants to serve real users, businesses, and institutions, then not everything can stay fully public forever.

People want the benefits of being on-chain But they also want control over sensitive information. That is what makes Nox feel different from normal Web3 tools. It is not only about helping developers build. It is about helping developers build with privacy in mind.

OK, it's time to clarify three words people keep mixing up:
Privacy VS Confidentiality VS Anonymity

Builders, did you know you can open a support ticket directly from Telegram?

No forms, no waiting, just shoot us a message and our team picks it up

Bring privacy to your DeFi app without rewriting it.

Docs are solid, give it a read

[iExec RLC @iEx_ec]

The confidentiality layer on-chain finance has been waiting for.

🎙️Building Confidential Prediction Market: LIVE w/ DarkOdds https://t.co/YKxA17UROI

[iExec Developer @iExecDev]

You don't post your medical records on a billboard.
You hand them to one doctor.

Same logic on-chain:

addViewer(handle, auditor) → only that auditor decrypts that balance.

Selective disclosure: privacy by default, transparency on demand.

This is what Nox stands for.

[iExec Developer @iExecDev]

Nice shoutout from @Altcoin_daddy

The real unlock here is for devs. Confidential contracts inside an environment they already know turns private vaults, hidden positions and selective disclosure from theory into something you can actually prototype.

Hey builders

Nox is live on @arbitrum

RWAs, institutional DeFi, payroll, treasury flows… all the use cases that couldn't live on a fully transparent chain now have a path

Start integrating, docs are open 👇

[iExec RLC @iEx_ec]

Nox is live on @arbitrum testnet.

iExec brings Programmable Privacy to RWAs & DeFi:

✅ Encrypted smart contract execution
✅ Selective disclosure
✅ Auditability on demand

Nox is built for financial systems that cannot operate with full public transparency.

Start integrating ➡️ https://t.co/6oOGkBgMS0

Wondering how confidential agent payments actually work under the hood?

@martinlecl got you, LIVE in 6 hours

Don't sleep on this one

[iExec Developer @iExecDev]

How do you let an AI agent pay for stuff without leaking its keys or its data?

Spoiler: x402 for the rails, ERC-7984 for confidential tokens, TEEs for execution.

Martin breaks it all down next week 🔥

[iExec Developer @iExecDev]

Proud to see the @bondoncredit team heading to SF 🚀

Agentic credit that actually holds up powered by TEE on the iExec stack

Smash that @PlugandPlayTC Demo Day

[bond.credit @bondoncredit]

It’s the agents’ time to shine in sunny SF.

See you soon at the @PlugandPlayTC Demo Day.

One more time, huge congrats to the winners of the iExec Vibe Coding Challenge 🏆

🥈 RWAOS: Best Institutional Architecture
🥉 DarkOdds: Best Confidential Prediction Market

Real confidential apps, real code, GG to all builders 🛠️

The real insight: Nox isn't just hiding values, it's computing on them

• Diam → confidential price comparisons on sealed bids
• RWA OS → private transfers with selective disclosure
• DarkOdds → encrypted payout math at resolution

Private storage is easy, private logic is the unlock

[iExec Developer @iExecDev]

Shipping confidential logic shouldn't mean:
write → deploy → wait → check → repeat

It should just be: write → npx hardhat test

That's what we're cooking with @iexec/hardhat-nox

Coming soon
