iExec adds confidential tokens

iExec publicly demonstrated its new Confidential Token product on March 30, 2026 and is showcasing it at conferences such as EthCC while running a developer challenge to build on the stack. (messari.io) (binance.com) The Confidential Token is delivered as a reversible wrapper for ERC-20 tokens — that means an existing token can be converted into a wrapped, private version and later converted back to the original token without changing the underlying asset. (iex.ec) (dorahacks.io) Under the hood the feature is built on iExec’s Nox layer, which pairs normal blockchain smart contracts (the on‑chain programs that enforce rules) with off‑chain Trusted Execution Environments — secure pieces of hardware or software that run code without exposing the sensitive data they process. (dorahacks.io) (iex.ec) The Confidential Token implementation keeps balances and transfer amounts encrypted off‑chain while the chain receives cryptographic proofs that a transfer is valid, and it includes selective disclosure so specific third parties (for example auditors) can be granted access to decrypt particular records on demand. (iex.ec) (binance.com) iExec has been positioning this privacy stack for Layer‑2 networks and already integrated TEE‑based tooling with Arbitrum, and the company says its native RLC token will be used to power privacy services and accounting inside that ecosystem. (chainwire.org) (decrypt.co) To accelerate adoption iExec is running the Vibe Coding Challenge (March 24–May 1, 2026) that invites builders to create confidential apps on Nox using the new Confidential Token primitives, with API credits and a prize pool for participants.
