Developer resources#

The following developer resources help you get started developing on the Concordium network.

Official resources#

  • See Node setup for information about the requirements to run a node and the available platforms for nodes.

  • See SDKs and APIs for links to SDKs and APIs for development

  • See Smart contracts for general information about smart contracts

  • GitHub

  • Concordium standards and updates

  • See How to create proofs for dApps and services for information about how to write statements that interact with Concordium wallets.

  • For information about how to create proofs to verify identity for dApps and services see Create proofs.

  • See dApp examples for a list of dApp examples and their resources.

  • For testing purposes, a node is available on testnet to use when testing smart contracts and dApps. You can use this node for API calls of chain methods only with gRPC v2 and gRPC web. The address is on port 20000 (gRPCv2 and gRPC-web). You can use this node for API calls of chain methods only. This node is maintained by Concordium, but Concordium does not guarantee availability. The status of this node is available on the Testnet status page.

  • The VSCode extension can help you develop Concordium smart contracts. The extension sets up the editor for development, installs the cargo-concordium smart contract development tool for all supported platforms, and provides commands in the editor for the essential workflows, such as building and testing smart contracts.

  • An external transaction logger service

Concordium Proof Explorer#

If you want to familiarize yourself with how proofs work and can be constructed, you can use the Concordium Proof Explorer to create proofs and send them to a Concordium Wallet for Web to see how they interact with account credentials and verifiable credentials. The Concordium Proof Explorer works on Testnet. You can use the Web3Id Issuer Front End to create verifiable credential to test with the proof explorer.

Example dApps#

Concordium has a selection of example dApps that you can clone to make your own dApps or for inspiration. Additionally, all of these example dApps are hosted so you can try the functionality on Concordium’s testnet.

Block explorers#

The following are links to the block, node, and status explorers.
