1) Add WalletConnect button element to connect user wallets. 2) Add Toolblox Workflow element to call transitions or load data from a workflow. Multiple elements can be added to call many smart-contracts.
3) If you need to upload data to IPFS (free decentralized file storage) - add the Toolblox Web3Storage element.

Prerequisites:
1) Create smart contract workflow in toolblox.net
2) Configure WalletConnect Project Id, Toolblox API Key and, optionally, Web3Storage Token in plugin settings.
3) To access properties of the Workflow item in Bubble, configure a new API Connector to act as object proxy.
