Cardano: Smart Contracts Done Right

Build on the world's first peer-reviewed blockchain. Cardano's scientific approach delivers formally verified smart contracts that are secure by design.

Why Cardano for Smart Contracts?

🔬

Academic Rigor

Every feature is peer-reviewed by academics and formally specified before implementation.

🛡️

Formal Verification

Mathematical proofs ensure your smart contracts behave exactly as intended.

⚡

Sustainable & Scalable

Proof-of-stake consensus uses 99% less energy than proof-of-work chains.

Cardano's Unique Advantages

Extended UTXO Model

Cardano's eUTXO model combines Bitcoin's security with Ethereum's programmability.

Benefits:

  • Predictable transaction fees
  • No failed transactions eat fees
  • Parallel transaction processing
  • Better security properties
# Transaction always succeeds or fails completely
validator :: Datum -> Redeemer -> ScriptContext -> Bool

Plutus Smart Contract Platform

Write smart contracts in Haskell with the full power of functional programming.

-- Example: Time-locked vesting contract
vestingValidator :: VestingParams -> () -> () -> ScriptContext -> Bool
vestingValidator params () () ctx =
  let
    info = scriptContextTxInfo ctx
    signedByBeneficiary = txSignedBy info (beneficiary params)
    deadlineReached = contains (from $ deadline params) (txInfoValidRange info)
  in
    signedByBeneficiary && deadlineReached

Native Multi-Asset Support

Create tokens without smart contracts. First-class multi-asset ledger.

  • No smart contract needed for basic tokens
  • Same security as ADA
  • Minimal fees for token transfers
  • Built-in token bundles in transactions

Marlowe for Financial Contracts

Domain-specific language for financial contracts. No coding required.

Perfect for:

  • Escrow agreements
  • Swaps and options
  • Loans and bonds
  • Insurance contracts

Hybrid Solution: XRP + Cardano

Real-World Example: Decentralized Marketplace

XRP Handles:

  • • Instant payments between users
  • • Order details in memo JSON
  • • Real-time notifications
  • • Cross-border settlements

Cardano Handles:

  • • Escrow smart contracts
  • • Dispute resolution logic
  • • Reputation tokens
  • • Governance mechanisms

Integration Pattern:

1. User initiates purchase with XRP payment (includes order JSON in memo)
2. Cardano smart contract receives notification via oracle
3. Contract locks funds in escrow until delivery confirmed
4. Upon confirmation, contract releases payment
5. XRP transaction with completion details notifies all parties
