Darwinia Crab Network (referred to as: Crab Network) is an economically valuable canary network for Darwinia, and its positioning is similar to that of Kusama Network for Polkadot. Expect Chaos is a reasonable expectation. The Crab network is mainly to provide an advanced simulation environment for Darwinia's upgrade and application deployment, and to conduct various radical experiments. The Crab network not only includes a complete software operating environment and network environment, but also includes the economic environment of economic games.
Crab network is the first cross-chain NFT chain in the Polkadot ecosystem. It provides smart contract solutions, is compatible with the Ethereum virtual machine, and supports Defi, NFT and other Dapps to easily migrate to Polkadot. Relying on the bridge technology innovation of the Darwin network, it also provides an entrance to the Polkadot ecology for projects that have been deployed on public chains such as Ethereum and BSC. The parameters of the Crab network are the same as those of the Darwinia main network, and use the same staking mechanism and inflation model.

There are two kinds of tokens in Crab Network. They represent different economic strategies of Crab Network. They are intended to make Crab more rational and stable.

The native token of Crab Network is CRAB, which can be used as gas for transactions. Gas includes transaction fees, contract execution fees, network bandwidth fees, storage fees, etc.
In order to encourage users to make long-term commitments, users can choose to lock CRAB for 3-36 months during the Staking process, and the system will provide CKTON tokens as rewards for users participating in Staking.
