Development network and test contracts.

Development Contracts Node

We provide a patched substrate-contracts-node to run your test network.

Running

Run the development node

docker run -p 9944:9944 --rm ghcr.io/web3labs/finality-contracts-node:latest

You will see an output similar to this one

Now you can connect with Polkadot.js explorer to the node

Example Contracts

Example ink! smart contracts are stored in the folder example-contracts/. To build the contracts in such a way that they can be verified through the ink! Verifier Service, check out the documentation for generating verifiable packages. We also have a tutorial that explains in detail how to build, upload and verify your contract.

If you want to skip the step of generating the package, you can also find generated packages in the folder verifiable-packages/. We have the contracts built for both ink! 4.0.0-beta (for uploading to Rococo-Contracts parachain) and also ink! 4.0.0-alpha.3 (for uploading to our local testnet). More information about the support of different versions is available here.
