Introduction Cross-Chain Mapping Token $xWRING
With Darwinia 1241 and Crab 1240 Runtime Upgrade, the bridging method between Darwinia Network and Crab Network has changed significantly — Instead of bridging between
Darwinia Chain and
Crab Smart Chain, we will directly support bridging between
Darwinia Smart Chain and
Crab Smart Chain, which brings a bridging paradigm between substrate-based chains that support frontier EVM module.
- Bridge between
Crab Smart Chainis no longer supported.
- The old cross-chain mapping token xRING on
Crab Smart Chainhas been renamed to xRING(Classic), and please migrate your xRING to the new cross-chain mapping token xWRING on
Crab Smart Chainvia the Migration Tool.
You may be a little unfamiliar with the cross-chain mapping token xWRING from
Darwinia Smart Chain to
Crab Smart Chain. We'll focus on that below. But before that, we need to understand Chains in the Darwinia Network.
There are three types chains in the Darwinia Network, namely Darwinia Chain(DC), Darwinia Smart Chain(DSC), and Darwinia Parachain(DP). DC and DSC provide two sets of different interfaces and chain structures but share the same nodes network, state storage, and native token(RING).
Darwinia Chain (DC) is designed to be the primary chain for tokens and governance, main communication hub and routing point of LCMP, and will support most on-chain light clients for other public chains.
DC is a public chain that can operate independently with its own consensus and security model, with its core business and application services, including cross-chain functionality of each application chain, controlled by DC itself.
Darwinia Smart Chain
Darwinia Smart Chain (DSC) is a full EVM-compatible smart contract platform hosted on DC and is designed to provide greater programmability for Dapps and cross-chain users. The projects from the Ethereum ecosystem can be easily migrated to the Darwinia Network.
DSC does not have its own economy.
Darwinia Parachain (DP) is designed to be protected by the shared security of the Polkadot Relay Chain. It will integrate Polkadot’s XCMP, open channels with other parachains, and connect to DC via LCMP. Darwinia Network has won the 21st Polkadot parachain slot and will be connected to Polkadot Relay Chain very soon, meanwhile, will build a hybrid cross-chain network for Polkadot.
Cross-Chain Mapping Token
Darwinia ChainNative Token: RING
Darwinia Smart ChainNative Token: RING
Darwinia Smart ChainWrapped Token Of Native Token: WRING
WRING exists on
Darwinia Smart Chainas the wrapped contract token of native token RING, positioning similar to Ethereum's ETH and WETH.
- Cross-Chain Mapping Token Of RING From
Crab Smart Chain: xRING(Classic)
- Cross-Chain Mapping Token Of WRING From
Darwinia Smart ChainTo
Crab Smart Chain: xWRING
xWRING can be understood as a composite symbol, xWRING = x + [W + (RING)].
What‘s The Impact On Users?
Darwinia will directly support bridging from
Darwinia Smart Chain to
Crab Smart Chain, users can:

About Darwinia Network
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 for Polkadot.
