Watch on YouTube: Building a Production Cardano SDK: From Validators to dApp

Highlights​

  • How community savings groups work, where social trust can fail, and the experiment: what happens when the treasurer is a validator?
  • The three-layer architecture: Aiken validators, the Effect-based SDK, and the demo dApp.
  • CIP-68 token pairs for on-chain identity.
  • ProgramRunner execution modes (unsafeRun, safeRun, and program) and the typed error taxonomy.
  • CLI demo: creating an account on Preprod and inspecting the CIP-68 token pair.
  • Demo dApp: creating a circle, joining from another wallet, and observing the pooled funds increase.
  • Q&A on first-recipient default risk, dispute handling, guarantor models, and future multisig governance.
