Safe{Con}2 Workshop - From Key Management to Custom Metadata and Relayed Calls

Program

The goal of this workshop is to present a few features enabled by account abstraction and the LUKSO "Universal Profiles" standards.

🔑 Key Management

In this example we will present and demo the Key Manager (based on LSP6).

📝 Custom Metadata

The LUKSO standards supports custom metadata (based on ERC725Y). These metadata can be used for storing NFT information, profile information, received tokens, or anything you need.

📢 Relayed Calls

The LUKSO Universal Profile account (based on LSP0) unlocks relayed calls capabilities and gasless transactions. This example will show how to relay a message.
