Cadence Advantages

This series explores the unique advantages and capabilities of Cadence smart contracts on Flow, demonstrating how Cadence's innovative features enable powerful development patterns that aren't possible on other blockchain platforms. From native data availability to seamless transaction composition, these tutorials showcase why Cadence represents the future of smart contract development.

Tutorials

Compose with Cadence Transactions

Learn how to compose with someone else's on-chain contracts by writing a Cadence transaction that conditionally calls a public contract on testnet, then extend it to mint NFTs when conditions are met—no redeploy required. This tutorial demonstrates Cadence's powerful composition model, showing how you can build complex application logic that interacts with multiple contracts in a single atomic transaction. You'll work with the Flow CLI dependency manager, learn to set up NFT collections, and view results using Flowscan.

Native Data Availability with Cadence Scripts

Discover how Cadence scripts provide native data availability, allowing you to query any on-chain data directly from Flow's state without relying on external indexers or APIs. This comprehensive tutorial shows you how to build scripts that can discover and query NFT collections across multiple child accounts using Hybrid Custody, then extend it to include both NBA Top Shot and NFL All Day NFTs. You'll learn to filter and process NFT collections, extract specific metadata, and compare Cadence's native data availability with Solidity's limitations.

Conclusion

Cadence's unique features—from resource-oriented programming to native data availability and seamless transaction composition—represent a fundamental advancement in smart contract development. These tutorials demonstrate how Cadence enables developers to build sophisticated applications with capabilities that simply aren't possible on other blockchain platforms, while maintaining security and developer experience as core principles.
