latestRoundData()in your contract. - Use Chainlink VRF for provably fair random number generation in gaming, NFTs, and lottery applications.
- Set up Chainlink Automation (Keepers) to trigger smart contract functions based on time or custom conditions.
Key Features
- Decentralized price feeds provide highly accurate, tamper-resistant price data for thousands of asset pairs across DeFi.
- Chainlink VRF generates cryptographically provable random numbers for fair gaming, NFT minting, and lotteries.
- Automation (Keepers) reliably triggers smart contract functions based on schedules, price thresholds, or custom logic.
- CCIP (Cross-Chain Interoperability Protocol) enables secure cross-chain token transfers and messaging.
- Proof of Reserve verifies that tokenized assets and stablecoins are properly backed by their claimed reserves.
