Don't let this gap widen
Companies that ignore blockchain checkout sessions lose market share to the competition.
Studies show that 65% of Web3 projects fail due to a lack of internal expertise in decentralized payments.
Developers without these skills see their careers stagnate with salaries 30% lower.
Not taking this certification training exposes your organization to costly delays and rapid skill obsolescence.
Act now to secure your professional future.
Participants discover the basics of Checkout sessions on blockchain through practical exercises on Remix IDE and Ganache. They explore Web3 concepts, create a first simple smart contract, and test payment flows. Real-world enterprise cases illustrate DeFi use cases. At the end of the day, each learner delivers a functional and documented basic contract to validate the training outcomes.
This day deepens Checkout sessions with intermediate Solidity features. Professionals use Hardhat to deploy contracts on testnet, integrate price oracles, and simulate DeFi payments. Pair workshops on real enterprise scenarios help consolidate skills. The final deliverable is a complete checkout module with unit tests and a technical report.
Learners connect their Checkout sessions to existing DeFi protocols using Web3.js and MetaMask. They deploy automated payment flows, manage gas fees, and secure transactions. Concrete case studies from blockchain companies guide the exercises. Each participant submits an integrated prototype ready for a production environment, certifying the training outcomes.
The final day focuses on production deployment of Checkout sessions and their continuous optimization. Professionals learn to monitor contracts with Tenderly, manage updates, and audit Solidity code. A collective final project simulates a full rollout for a company. Deliverables include a monitoring dashboard and a presentation of results to validate certification.
