@ton-community/tx-emulator has been rebranded into @ton-community/sandbox and significantly improved!

It now uses the new ton-core under the hood and is compatible with all the APIs that it provides, making the creation of smart contract wrappers easier than ever!

More importantly though, the blockchain-experimental features have been merged, so you can now emulate whole chains of transactions and even emulate interactions with existing smart contracts from real networks (both mainnet and testnet)!

Together with it we released another package, test-utils, which, along with the new features of sandbox, significantly simplifies testing of systems of multiple smart contracts.

Check out the examples provided together with sandbox to see the intended way to use it.

Please note that this tool is still in beta, but we would love to hear any feedback from you!

Also, stay tuned for more detailed tutorials for using this tool!
