Solana Stablecoin & CCIP Workshop Recap

Superteam Korea kicked things off, highlighting why stablecoins are such a central theme in Korea’s blockchain landscape and how Chainlink is powering the next phase of tokenized finance. Participants built a cross-chain stablecoin prototype on Solana using Chainlink Data Streams and CCIP (Cross-Chain Interoperability Protocol) to connect price feeds and automate value transfer.

1. Workshop Overview

The session was split into two technical modules, each pairing conceptual walkthroughs with hands-on development.

1.1 Session 1 — Oracle & Data Streams

The first session introduced Chainlink Data Streams, a low-latency oracle solution that delivers real-time price updates to Solana smart contracts.

Participants learned:

• How Data Streams SDK connects off-chain clients to on-chain Oracle programs.
• How the Oracle verifies signatures and timestamps via a Verifier Program.
• How the verified data is stored on-chain in a Storage Account for later use.

The instructor demonstrated each step live: deploying the Oracle Program using Anchor, sending a Data Stream report, and checking Solana logs for verification results.

1.2 Session 2 — Stablecoin Minting & CCIP Integration

The second half of the workshop focused on building a cross-chain stablecoin using the verified oracle data.

The workflow:

1. Deposit: A user deposits SOL into the Stablecoin Program.
2. Mint: The program fetches the verified oracle price and mints an equivalent USD-pegged stablecoin.
3. Transfer: Using Chainlink CCIP (Cross-Chain Interoperability Protocol), the stablecoin is securely sent to Ethereum testnet — burned on Solana and re-minted on the destination chain.

Participants also explored how CCIP’s components, Router, Token Pool, Token Manager, and Fee Quoter coordinate the entire cross-chain process through General Messaging Protocol (GMP).

The instructors emphasized that while this workshop skipped liquidity pool or re-pegging logic, it effectively demonstrated the core infrastructure that makes cross-chain stablecoin transfers possible.

2. What Builders Learned

• End-to-End Architecture: Off-chain client → on-chain oracle → stablecoin mint → CCIP transfer.
• Security Design: Signature validation, timestamp checks, and anti-replay nonces.
• Scalability: Using Chainlink Automation to trigger updates without manual intervention.

The workshop showed how modular Chainlink infrastructure can extend beyond price feeds to complete interoperability solutions for multi-chain finance.

Final Takeaway

“Today’s stablecoin demo was a micro-version of the future RWA economy, data-verified, cross-chain, and automated through Chainlink.”

This workshop didn’t just teach Solana syntax; it illustrated how trusted computation can redefine financial infrastructure for developers and institutions alike.
