Crab Network Features
- Providing smart contract solutions: Crab Network DVM is compatible with the Ethereum virtual machine, and supporting Dapps such as Defi and NFT to easily migrate to Polkadot and Pangolin testnet.
- Cross-chain interoperability: Relying on the innovative bridge technology of the Darwinia Network, it also provides an entrance to the Polkadot ecology for projects that have been deployed on public blockchains such as Ethereum and BSC.
- Evolution Land Crab Continent GameFi system: The new continent of Darwinia ecosystem cross-chain game Evolution Land has been deployed on Crab, will soon launch the new NFT+Defi GameFi system.
- Faster and easier user experience: Crab network can bring users a very high-quality experience, including very low transaction fees and ultra-fast transaction confirmation speed.
Crab Network is going to participate in the Kusama Parachain Slot Auction
Kusama is a multi-chain network. Parachains can be accessed through slots. Parachains and Kusama jointly form an interoperable blockchain network. Kusama guarantees the security of the entire network, while parachains provide a variety of capabilities for the entire network. All parachains must participate in the parachain auction to obtain the right to rent a slot.
The Crab network needs to crowdloan enough KSMs to win the parachain auction. Crab Network chooses to crowdloan KSMs in a trustless way. During Crab’s parachain lease, these KSMs will be “locked” in the Kusama Crowdloan.
KSM holders lock their tokens in the Crowdloan for a period of time (48 weeks) to help Darwinia Crab rent a slot. In return for these KSM holders, participants will receive CRING, RING, NFT, BTC as rewards.
Crab PLO Strategy
PLO Strategy
- Bidding Period: Considering the first few parachains to connect may experience stability issues, we plan to begin bidding for a slot in the 4th round.
- Range: Lease periods on Kusama are 6 weeks long and we will bid for a block of four, making our lease duration 6 months. The longer lease duration will ensure long-term stability of Crab network.
PLO Rewards
We have set aside 25% of CRING and 1% of RING token supplies for Kusama PLO over the next 10 years.
In addition, Evolution Land NFT rewards (land, chests, apostles) on the Columbus continent launched on the Crab network and Dawning continent launched on Heco Chain will be provided to supporters after successful bidding.
Our super jackpot is 1 BTC, and one lucky user will find this BTC when they claim their land.
Guaranteed rewards
Every 1 KSM donated by supporters of Crab during the Crowdloan will earn a reward of about 25 CRING per day immediately at the end of the auction.
For example, Alice contributes 10 KSM on the third day of the Crowdloan and the Crowdloan lasts 7 days.
Then Alice is expected to win 5*10*25, 1250 CRING in total.
Rewards for a successful bid
After successfully winning the slot, we will distribute a 240,000,000 CRING prize pool and a 6,000,000 RING prize pool.
Supporters will share the prize pool rewards according to their percentage share of total contributions in the Crab Crowdloan Fund.
30% of the prize pool will be released immediately and the remaining 70% will be vested for 48 weeks and released in a linear fashion according to a weekly distribution schedule.
For example, Alice joins in to support the Crab Crowdloan and contributes 10 KSM.
She is expected to earn:
Also at the same time, our supporters will receive one lottery ticket for every KSM contributed. The lottery tickets will be valid during the draw for Evolution Land NFT prize packages, including:
- 1 : 10 is the proportion of Gold Chest to Silver Chest.
- Lottery tickets will expire 20 days after Crab successful bidding.
BTC Prize Lotto
In addition to NFT rewards, We will also offer a Mystery BTC Super Prize hidden somewhere in the NFT land. Within 20 days after the parachain auction is finished, all players who get the Evolution Land NFT Legendary Package lucky draw will have a chance to win the BTC lotto prize!
How to qualify for winning the BTC Lotto
For example, Alice participates in the Crab crowd loan and contributes 10 KSM; in return she receives 10 lottery tickets. Within 20 days after Crab wins the parachain, Alice is able to participate in the Evolution Land NFT package lottery and if she is lucky enough, will win a Legendary NFT reward (including land, apostle, drill.)
The BTC Super Prize is hidden in the NFT land reward, so Alice has a chance to win the 1BTC jackpot.
How to win the BTC Lotto
The total number of users who are eligible to participate in the BTC lottery is recorded as n (that is, the total number of users who have won the Legendary NFT package), we will take the hash of future bitcoin chain block modulo n and mark the remainder as m. The user who draws the m-th land in chronological order will win the BTC Prize. In order to ensure the fairness of the results, we will post them on Github.
To see the list of players who won through the lottery, please stay tuned! We will post the winners list on the Crab official website and our social media channels.
How to develop on Crab
Crab is compatible with the Ethereum Virtual Machine (DVM). DApp Based on the Ethereum virtual machine, can be migrated to the Crab network seamlessly or with a small amount of modification. More projects that have been deployed on other public chains after the cross-chain bridge is opened can directly choose to develop on Crab and easily enter the Polkadot ecosystem.
Whether it is a new deployment or a migration, Darwinia Dev Team provides technical support, developers can test on Pangolin testnet.

About CRING
CRING is the token of the Darwinia Crab network, CRING holders can participate in staking and on-chain governance.
Crab has the same parameters as Darwinia Mainnet, and uses the same Staking mechanism and inflation model. Crab’s tokens are CRING and CKTON, the initial supply of CRING is 2000M, and the initial supply of CKTON is 0.
Crab Network is a long-term valuable network. Some RINGs are allocated to Crab Network as backing assets to make it serve as a canary network with real economic incentives and massive gaming theory testing, not just working a testnet.
