Cardano2VN Teaches Developers to Build Token Swap Apps
The free Building with Aiken course adds three lessons on creating a Cardano swap application, from smart contract logic to a working browser interface.

Cardano2VN has expanded its Building with Aiken course with a third module focused on peer-to-peer token swaps. The module combines video instruction and public source code to teach developers how to build an application for creating, accepting and cancelling exchange offers.
Token Swaps Within Cardano
The application lets a user lock assets under predefined exchange conditions. Another participant can fulfil those conditions to complete the swap, while the offer’s creator can cancel it and retrieve the locked assets.
The exchange takes place entirely within Cardano. Lessons connect the network’s handling of ADA and native tokens with the validation rules controlling how contract-locked assets are spent.
Security exercises address “double satisfaction,” a vulnerability in which one payment can incorrectly satisfy conditions attached to multiple contract inputs. The module examines checks designed to prevent that behavior.
Connecting Aiken, MeshJS and Next.js
Each technology handles a distinct part of the application. Aiken defines the on-chain spending rules, MeshJS constructs transactions, and Next.js provides the user interface.
The project-based format takes learners beyond an isolated contract. They also build the components needed to connect a wallet, interpret a user’s action and submit the corresponding transaction.
The swap module follows Secret Number and Vesting. The broader roadmap covers 12 projects, including NFT membership, multisignature treasury management, marketplaces and peer-to-peer lending. This describes the planned course scope, not the number of completed video modules.
Free Cardano Learning Resources
Building with Aiken received a 43,500 ADA allocation through Catalyst Fund 13. The proposal targets developers who are not native English speakers, providing free instruction and open-source examples for Cardano application development.
The swap code is an educational resource. The reviewed materials do not establish an independent security audit or readiness to manage real funds.
Vietnamese video lessons are linked from the forum announcement alongside the Cardano2VN learning platform. The public GitHub repository contains the application code, with English versions of the introductory documentation and course outline available to developers outside the Vietnamese-speaking audience.
