The Learni story
Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1ERC-721 Fundamentals: Implement the standard interface with OpenZeppelin (Solidity, Hardhat)
Dive into the advanced ERC-721 interface extension using OpenZeppelin libraries for a solid and secure foundation, set up your Hardhat environment for rapid unit tests, implement core functions like balanceOf and ownerOf on real enterprise cases, perform practical minting exercises with gas optimization, and produce a first deployable and audited contract in a group to validate professional skills.
Module 2Advanced ERC-721 Token Management: Minting, Burning, and Secure Transfers (Foundry, Deployment Scripts)
Master batch minting and conditional burning mechanisms in ERC-721 for dynamic NFT collections, use Foundry for advanced fuzzing tests and attack simulations, develop automated deployment scripts with customizable parameters, apply these skills to a red thread enterprise project like an NFT gallery, optimize events for perfect indexing on Etherscan, and end with a collaborative code review to boost your professional blockchain skills.
Module 3Metadata and Royalties in ERC-721: Integrate ERC-2981 and Dynamic URIs (IPFS, Pinata)
Integrate advanced JSON metadata with dynamic tokenURI for unique and evolving NFTs, combine ERC-721 with ERC-2981 for automated royalties on secondary sales, upload to IPFS via Pinata for full decentralization, test real cases like generative artworks in an enterprise setting, develop hooks for post-mint metadata updates, produce a complete deliverable with documentation for marketplaces, and gain autonomy for certifying Web3 projects.
Module 4ERC-721 Integrations: Marketplaces and Off-Chain (OpenSea, Moralis, The Graph)
Connect your ERC-721 contracts to OpenSea and Rarible via metadata standards and lazy minting, integrate indexers like The Graph for performant subgraph queries, use Moralis for secure real-time off-chain APIs, simulate sales and transfers on a mock marketplace in-person, apply to an enterprise case like a play-to-earn game, optimize gas fees for scalability, and finalize an integrated prototype ready for production to enhance your professional skills.
Module 5ERC-721 Security and Deployment: Audits, Upgrades, and Production (Slither, Echidna, Mainnet)
Audit your ERC-721 smart contracts with Slither and Echidna to detect reentrancy and overflows, implement proxy patterns for upgrades without downtime, deploy on Sepolia then Ethereum mainnet with multisig wallets, analyze real hacks like those on OpenSea to strengthen your code, produce a complete audit report and monitoring plan, and conclude with a red thread project defense to certify your advanced professional blockchain development skills.

* contact us for remote delivery feasibility** ratio varies depending on the program
Skills assessment methods
Assessment of skills acquired during the Training ERC-721 - Developing Secure NFT Smart Contracts program is performed through:
- During training: case studies, hands-on labs and professional scenarios
- End of training: self-assessment questionnaire and skills evaluation by the trainer
- After training: completion certificate detailing acquired skills
Program accessibility
Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.
Enrollment terms and lead times
Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.
Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
