Why this program matters

  • Without expert ERC-721 mastery, 65% of NFT smart contracts suffer security exploits costing an average of 3M€ per incident according to Chainalysis 2023, exposing your company to massive losses and customer trust erosion in an NFT market projected at 230Md$ by 2030 by Statista.

  • Your projects stall against decentralized competition, with exorbitant gas fees blocking 40% of scalable deployments, while your skills rapidly become obsolete amid EIP evolution such as ERC-721A.

  • Major career risk: displacement by certified devs who master extensions and audits, missing Web3 opportunities at leaders like ConsenSys.

  • Invest now in expert training to secure your blockchain future and boost NFT project ROI.

ERC-721 curriculum: 1 module over 1 day

Module 1 : Advanced ERC-721: Implementation of Extensions and Security Optimization (Solidity, Hardhat, OpenZeppelin)

Dive into ERC-721 extensions such as EnumerableSet and dynamic URI via OpenZeppelin, develop custom smart contracts with automated royalties and secure burning mechanisms, perform practical exercises on Remix and Hardhat to test multisignature compatibility, analyze concrete cases of exploited vulnerabilities on Polygon and Optimism, optimize gas costs with advanced patterns like lazy minting, produce a complete deliverable: an ERC-721 contract deployed and tested on testnet with integrated basic audit, while incorporating best practices for enterprise scalability in interactive e-learning.

How ERC-721 skills are assessed

  • Advanced technical quiz on ERC-721 extensions and Solidity security
  • Case study: audit and optimization of a real NFT smart contract
  • Final project: deployment of a custom ERC-721 with expertise report

How the ERC-721 course is taught

  • Intensive practice on live Ethereum testnet environments
  • Concrete use cases drawn from enterprise NFT projects like Bored Apes
  • Video replay tutorial support and advanced OpenZeppelin resources
  • Live Q&A interactions with certified blockchain experts

ERC-721 training: access and practical arrangements

The Training ERC-721 - Developing Advanced Secure NFTs program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training ERC-721 - Developing Advanced Secure NFTs program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

Skills assessment methods

Assessment of skills acquired during the Training ERC-721 - Developing Advanced Secure NFTs 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.

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.

Our method

How Learni guarantees the quality of your ERC-721 training

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.

FAQ

ERC-721: frequently asked questions

Which tools are used in ERC-721 training?+
Hands-on work runs on solidity, hardhat and openZeppelin. Those tools come from the ERC-721 program itself, delivered on site over 1 day, so participants practise on the stack they will use at work.
What can participants do after ERC-721 training?+
They can master advanced ERC-721 extensions to implement highly secure professional NFTs, develop optimized ERC-721 smart contracts with Enumerable and Metadata for scalable enterprises and design custom royalties and burning mechanisms in ERC-721 certifying blockchain skills. Those are the stated objectives of the ERC-721 program at Expert level, checked by the end-of-session assessment.
How is ERC-721 training assessed?+
Assessment relies on advanced technical quiz on ERC-721 extensions and Solidity security, case study: audit and optimization of a real NFT smart contract and final project: deployment of a custom ERC-721 with expertise report. Learni issues a completion certificate together with the individual assessment report at the end of the ERC-721 program, which an L&D team can file as evidence.
How much does ERC-721 training cost per participant?+
ERC-721 training costs $1,155 per participant. For an in-company team, the flat rate starts at $2,195 for the whole group, up to 8 people. The detailed quote, sent within one business day, adjusts the amount to the format and how far the syllabus is tailored to your team.
How long does ERC-721 training take?+
1 day, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.
Who pays for ERC-721 training?+
Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.
What do participants need to know before ERC-721 training?+
Advanced mastery of Solidity, development and deployment of basic ERC-20/ERC-721 smart contracts, use of tools like Hardhat, Remix, and Ganache, in-depth knowledge of Ethereum and EIP standards.
Is a certificate issued after ERC-721 training?+
Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
Does Learni provide the equipment for ERC-721 training?+
No. A computer and a stable internet connection are required for each participant. Learni provides the learning platform, the trainer and all course materials.
