Quick guide#

Install Rust
Install cargo concordium or the Concordium smart contract VSCode extension
Install concordium-client
Import a wallet key into concordium-client
Install Concordium Wallet for Web

These setup steps are explained in detail here. An overview of the developer documentation will help you to find the topics that you are interested in.

Note

There is a public Concordium testnet node available at node.testnet.concordium.com on port 10000 (GRPCv1) and port 20000 (gRPCv2 and gRPC-web). You can also run your own node, but that will take some time to catch up to the newest blocks and thereby be usable.

You can check that you have access to the node by executing the command:

$concordium-client consensus status --grpc-port 20000 --grpc-ip node.testnet.concordium.com

The command will return a list of values relevant to the consensus if you have a connection to the Concordium testnet node.

DApp examples#

An overview of different dApp examples is available to get started.
