⭐ Features

Snapshot Management

Implemented by the community FLIP Fest: (#92) @bluesign 🙌
The new snapshot feature exposes a new emulator management HTTP API allowing you to commit a new block on demand and save and restore from a snapshot. Committing a new block is possible by calling endpoint GET /emulator/newBlock whereas saving or restoring from a state is possible with a call to GET /emulator/snapshot/{name} - in case there is no existing state by that name it will create a new one or if there is an existing state it will restore to that moment in the blockchain.

Predeployed Contracts

Implemented by the community FLIP Fest: (#88) @mwufi 🙌
The emulator can be started with even more pre-deployed contracts. Use the --contracts flag and FUSD, NonFungibleToken, ExampleNFT, NFTStorefront will be deployed for you. If there are more contracts you wish to add to this list please feel free to create a PR on the emulator repository.

Dev Wallet Integration

Implemented by the community FLIP Fest: (#90) @bluesign 🙌
The emulator is featuring dev wallet integration. You can easily start dev wallet by starting the emulator with --dev-wallet flag and even specify a port on which the dev wallet will be listening with a --dev-wallet-port flag. This way you have a more complete set of features already integrated in your dev environment.
