“I found CRAB and WCRAB on Crab Smart Chain, and xWCRAB on Darwinia Smart Chain, what should I understand about these token symbols? And how can I get them?”

Let’s clear the token parameters of Crab chains first:

Crab Chains Token Parameters

Crab Parachain Native Token: CRAB
Crab Chain Native Token: CRAB
Crab Smart Chain Native Token: CRAB
Crab Smart Chain Wrapped Token Of Native Token: WCRAB

WCRAB exists on Crab Smart Chain as the wrapped contract token of the native token CRAB, positioning similar to Ethereum's ETH and WETH.

📌 NOTE: In order to make the protocol more concise and understandable, the Dev Team has decided to research and test the technical feasibility of the merge between Crab Chain and Crab Parachain.

Cross-Chain Mapping Token xWCRAB On Darwinia Smart Chain

Cross-Chain Mapping Token Of WCRAB From Crab Smart Chain To Darwinia Smart Chain: xWCRAB

xWCRAB can be understood as a composite symbol, xWCRAB = x + [W + (CRAB)].

Crab Network (Crab) is a canary network with real economic value for Darwinia, positioning similar to Polkadot’s Kusama Network. As Darwinia’s canary network, all new things come to the Crab first to be tried in live, therefore, Crab also contains 3 chains correspondingly, which are Crab Chain, Crab Smart Chain, and Crab Parachain. Crab Smart Chain of Crab Network positioning is similar to Darwinia Network's Darwinia Smart Chain.

About Darwinia & Crab

Darwinia is a cross-chain messaging infrastructure, which provides a light client-based, programmable, universal cross-chain messaging network for decentralized applications. Now, we’ve successfully used Darwinia’s light-client cross-chain messaging protocol(LCMP) to bridge cross-chain messages between substrate-based chains, and even between substrate-based chains and EVM chains, meanwhile, Darwinia provides developers with an SDK, so they can easily integrate cross-chain capabilities into their Dapps. This will have profound implications for cross-chain interoperability, and Darwinia as a cross-chain messaging infrastructure will facilitate the building of a hybrid cross-chain network.

Crab is a canary network with real economic value for Darwinia, positioning similar to Polkadot’s Kusama Network, which is a programmable cross-chain platform for Dapps. It is substrate-based, EVM-compatible, and connected to Kusama.
