XRPL Edition

Master the XRP Ledger
from consensus to production

Every module builds toward one real product

You don't do isolated exercises. From Module 00 to Module 14, you build a tokenized Real World Asset issuance platform. By the end, it can issue compliance-grade tokens, gate trading with on-chain KYC, escrow proceeds, and price assets with on-chain oracles.
