Overview

iExec is a French-based decentralized GPU marketplace for confidential computing, where tasks run in Intel TDX enclaves with on-chain proof. It’s for developers and enterprises needing privacy-preserving computation, not casual users. While legally transparent and technically robust, it lacks public pricing and has limited adoption, making cost evaluation difficult.

What you can rent

You can rent confidential computing capacity via iExec’s marketplace to run applications on GPU-accelerated, TEE-protected infrastructure. The service supports arbitrary workloads through Docker containers, executed in Intel TDX Trust Domains. You do not rent raw GPUs directly; instead, you pay RLC to execute specific tasks (iApps) on protected data. There is no self-serve hosting or direct GPU model selection.

Contract & terms

Contracts are flexible with no fixed term - each task is a separate on-chain agreement. RLC is staked during execution and unconsumed amounts are recoverable afterward. There is no published maintenance fee, refund policy, or uptime SLA. Payouts occur per completed task via automated on-chain settlement. Minimum stake and payout thresholds are not publicly specified.

Proof & verifiability

Yes, iExec provides hardware-attested proof: tasks run in Intel TDX enclaves, with remote attestation verified by the Secret Management Service. Proof of Contribution (PoCo) ensures on-chain validation of execution authenticity. This was audited by Consensys Diligence in 2020. Results are consensus-validated across workers, offering strong verifiability.

Reliability & history

iExec SAS is a registered French company (SIREN 823070925) with a documented legal address and nine years of operation since 2017. No red flags around fraud or non-payment exist. External sources note strong tech but poor market timing and low adoption. The 2026 migration from Bellecour to Arbitrum was transparently communicated, indicating operational continuity.

Pricing

iExec does not publish public USD or RLC prices per task - pricing is set dynamically by providers in the on-chain marketplace. Enterprise buyers must contact sales. You pay in RLC only, with no fiat option. No KYC is required for protocol use, but RLC staking is mandatory during task execution. Exact costs depend on task complexity and provider bids.

Verdict

iExec offers one of the most verifiable and legally clear decentralized compute environments, ideal for privacy-sensitive use cases. However, the lack of transparent pricing and limited adoption make it impractical for most users. Consider it only if you need confidential computing with hardware-level attestation.

// iExec FAQ

Is iExec legit?

Based on our checks as of 2026-09-24: iExec scores 6.3/10 in our weighted review. We logged no red flags. User reports and operator background are documented with dated sources in the meta-review below.

What do I actually get when I use iExec?

You get access to run verified, confidential computations in Intel TDX enclaves via the PoCo protocol. You do not own hardware or rent GPUs directly - instead, you execute tasks in a decentralized, privacy-preserving environment.

What are the total costs and fees?

There is no fixed fee structure. You pay RLC per task, with pricing set by providers in the marketplace. RLC is staked during execution and unconsumed amounts are returned. No additional fees are published.

Is there a minimum purchase or trial option?

Minimums are not publicly specified. You must stake RLC to run a task, but small test tasks are possible. No free trial is advertised, though low-cost testing may be feasible via the SDK.

How do payouts work?

Payouts are made in RLC per completed task, distributed automatically on-chain to the app, data, and worker providers. Settlement occurs after PoCo validates the TDX attestation and task completion.

What happens if iExec shuts down?

If operations cease, the decentralized nature and on-chain logic may allow continued use, but reliance on centralized components (e.g., Secret Management Service) could disrupt service. Your RLC remains in your wallet.

How does this compare to buying hardware or coins directly?

iExec offers confidential execution you can’t replicate with direct hardware or coin purchases. But for general compute or speculation, buying GPUs or RLC outright is simpler and more predictable.
