ERC-8004 Inference-as-a-Service: Build on Ethereum

Frequently Asked Questions

01.Can I start with an MVP for an Inference-as-a-Service layer?

Yes. A minimal viable IaaS layer requires only the ERC-8004 Identity Registry deployment, one off-chain inference node, and a basic payment escrow contract. Most operators ship an MVP in 12-16 weeks with a specialized partner. You can add reputation tracking and zkML validation in later sprints without redeploying core contracts.

02.What is included in a smart contract audit cost for an ERC-8004 IaaS deployment?

Audit cost for a standard ERC-8004 IaaS stack typically covers three registry contracts plus payment escrow logic. Costs range from approximately 15,000 to 40,000 USD depending on contract complexity and auditor tier. Timeline is usually two to four weeks. Always budget for a re-audit after any post-launch changes to registry logic.

03.How does ERC-8004 differ from running a private inference API?

A private inference API has no verifiable identity, no composable reputation, and no trustless payment settlement. ERC-8004 anchors every inference provider to an on-chain identity derived from ERC-721, publishes reputation scores that any smart contract can read, and enables payment rails that settle conditionally on validation results. This means your clients can verify provider trustworthiness without relying on your word alone.

04.Which Ethereum layer should I deploy my IaaS registry on?

Most operators deploy the Identity Registry on Ethereum mainnet for finality and composability, then route inference jobs and payments through a Layer 2 such as Base or Arbitrum to reduce gas costs. ERC-8004 launched on Ethereum mainnet in January 2026 and subsequently expanded to Base. Run heavy-throughput workloads on L2 and anchor critical reputation data to mainnet.

05.Do AI inference providers on ERC-8004 need to comply with MiCA?

MiCA primarily governs issuance and trading of crypto-assets, not AI inference services. However, if your IaaS platform accepts stablecoin or token payments, those token mechanics may fall under MiCA Article 45 disclosure rules. GDPR applies if you process any personal data during inference. EU AI Act obligations depend on the risk classification of the models you serve. Always obtain qualified legal counsel before going live in the EU.
