EVM Smart Contract Development for AI Provenance

We build custom, audited smart contracts on Ethereum and EVM chains to immutably record and verify AI-generated provenance data for NFTs, ensuring tamper-proof history and ownership.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, gas-optimized smart contracts built by Web3-native engineers.

We architect and deploy production-grade smart contracts that are secure by design and gas-optimized for mainnet. Our process ensures your core logic is robust and cost-effective from day one.

  • Full lifecycle development: From architecture and Solidity/Rust coding to deployment on EVM/Solana/Cosmos.
  • Security-first approach: Adherence to OpenZeppelin standards, comprehensive unit testing, and integration with leading audit firms.
  • Gas optimization: Every contract is profiled and refined to reduce user transaction costs by 15-40%.

We deliver contracts you can stake your protocol's reputation on, with a focus on upgradability, pausability, and clear administrative controls.

Our engineers specialize in:

  • DeFi Primitives: Custom AMMs, lending pools, yield aggregators, and derivative contracts.
  • NFT & Token Standards: ERC-20, ERC-721, ERC-1155 with advanced features like staking, royalties, and dynamic metadata.
  • Cross-Chain & Layer 2: Native development for Arbitrum, Optimism, Polygon, and bridge integration.

EVM DEVELOPMENT FOR AI PROVENANCE

Core Technical Capabilities

We architect and deploy secure, verifiable smart contracts that anchor AI model provenance, training data, and inference results directly on-chain, creating immutable audit trails for compliance and trust.

01

Provenance & Attribution Smart Contracts

Design and deploy custom ERC-721/1155-based contracts to tokenize AI models, datasets, and outputs. Each token's metadata immutably stores hashes of source code, training parameters, and data lineage.

02

On-Chain Verification & Attestation

Implement verifiable credential patterns (EIP-712, EIP-4844) for cryptographic attestations of model performance, bias audits, and regulatory compliance, signed by authorized validators.

Gas-Optimized Data Anchoring

Engineer cost-efficient methods for storing and referencing off-chain data (IPFS, Arweave, Ceramic) using event logs and Merkle proofs, minimizing on-chain storage costs by up to 90%.

DELIVERABLES & GUARANTEES

Business Outcomes for Your Platform

Our EVM smart contract development for AI provenance delivers concrete, auditable results that directly impact your platform's security, trust, and market position.

01

Immutable AI Model Provenance

Deploy custom smart contracts that permanently record AI model training data, parameters, and version history on-chain. This creates an unbreakable chain of custody for model lineage, enabling verifiable claims about model origin and preventing data poisoning or unauthorized modifications.

Automated Royalty & Attribution

Implement on-chain royalty distribution for AI-generated assets. Our contracts automatically execute micropayments to data providers, model creators, and fine-tuners based on verifiable usage, ensuring fair compensation and transparent economic flows within your ecosystem.

FROM CONCEPT TO PRODUCTION

Our Proven Development Process

A systematic, security-first approach to building AI provenance smart contracts that are secure, scalable, and ready for mainnet deployment.

01

Discovery & Architecture

We define your AI model's data lineage requirements and design a custom EVM architecture. This includes selecting the optimal data anchoring strategy (on-chain hashes, zk-proofs, or hybrid) and token standards (ERC-20, ERC-721, ERC-1155).

EVM Smart Contract Development for AI Provenance

Frequently Asked Questions

Common questions from CTOs and technical founders about implementing secure, auditable provenance for AI models and data on EVM blockchains.

A standard implementation takes 3-5 weeks from kickoff to mainnet deployment. This includes 1 week for requirements & architecture, 2-3 weeks for development and internal testing, and 1 week for a third-party security audit. Complex systems with custom consensus or multi-chain logic may extend to 8 weeks. We provide a detailed project plan with weekly milestones.
