Summary: ERC-6551 is a new NFT standard allowing NFTs to hold assets, interact with contracts, and have on-chain identity, enabling use cases like composability and provenance tracking.
What is ERC-6551:
- Gives NFTs capabilities of a smart contract wallet
- NFT can hold assets, interact with contracts, evolve over time
How ERC-6551 works:
- Uses registry compatible with ERC-721 NFTs
- Deploys proxy contract as token-bound account for each NFT
Use cases:
- Composability: NFT bundles assets
- Identity: Interact independently with dApps
- Provenance: Transaction history beyond ownership
- Dependency: Owns assets that enhance functionality
Challenges and limitations:
- Lack of support from major NFT projects
- Increased attack surface for hackers
- Added complexity for users
Conclusion:
- Could revolutionize NFTs by making them more dynamic
- But adoption and compatibility issues remain
