PolkaBridge ( https://polkabridge.org/) is a new DeFi made to be a bridge between Polkadot and other blockchains. It is a decentralized platform containing a DEX that gives us the option to Swap our assets from other blockchains to assets using the Polkadot blockchain. This interconnectivity is achieved without any centralized third party being involved. PolkaBridge when fully developed it will offer: a DEX with Swap option for native tokens of other blockchains and Polkadot tokens Lending Yield Farming for liquidity providers A deflation mechanism with 10% burn rate of fees A predictions market After connecting to the PolkaBridge launchpad (https://launchpad.polkabridge.org/#/) with Metamask we enter the main page of the platform: A complete tutorial on how to join the launchpad is given by the PolkaBridge team in this medium post: https://polkabridge.medium.com/polkabridge-launchpad-tutorial-50e8e80905d4 . It requires some steps as holding PBR or other properties that user has to set, and for each pool there are different requirements. There will be public pools with almost no requirements to join and private pools with certain criteria. Polkabridge contract is audited by CertiK.io. It is one of the first projects on Polkadot with the migration of PBR ERC20 token in the Polkadot parachain testnet in progress. The PolkaBridge token is already trading in Uniswap and a centralized exchanges Gate.io, MXC and Bilaxy.

As a Substrate-based open bridge protocol between chains, Darwinia focuses on building the future Internet of tokens, including the exchange, sharing, and marketing of decentralized tokens. Darwinia Network is the first chain of games in Polkadot. Darwinia Network development is based on Polkadot and Substrate framework. Later, Darwin network will become a parachute of Polkadot network. What is Darwinia Network Darwinia Network is an open protocol of decentralized heterogeneous cross-chain and a bridge chain built on substrate. Darwinia won the Web3 Foundation grant and joined the Substrate Builders program. Darwinia was selected to join the Web3 Foundation Bootcamp program. Darwinia focuses on building exchange, sharing and token market between decentralized chains. Darwinia also builds infrastructure for single-chain application upgrades, including Defi, games, DEX, NFT market, etc. Darwinia Network is part of the Polkadot ecosystem and, at the same time, it differs from Polkadot, Darwinia Network focuses on the cross chain token. Blockchain Dapps can easily perform cross-chain token transactions and transfers through Darwinia Network. For example, Cryptokitties can transform its NFT (Kitties) into Ethereum into NFT into EOS through the Darwinia chain; Ethereum players and EOS players can play the Evolution Land game simultaneously through the Darwinia network. At the same time, thanks to the Polkadot ecosystem, Darwinia Network can connect to a wider range of games and players. Main Characteristics: Interconnection of block chains In Polkadot Ecosystem Decentralized Economic Model RING> Darwinia Network native tokens are RING, RING can be used as a gas for transactions. The gas includes transaction fees, contract execution fees, network bandwidth fees, storage fees and more. KTON> To encourage users to make long-term commitments and promises, users can choose to block RINGs for 3 to 36 months in the Staking process, and the system will offer a KTON token as a reward for users who participate in Staking. Staking>The Darwinia Network will distribute RING as an incentive to Staking participants. The Staking process can also be understood as the POS mining process, where the miner obtains energy from Staking by committing tokens to POS mining. Token DEX is a decentralized application based on Darwinia's cross chain bridge as the core technology, which can perform automatic cross chain transactions between tokens. NFT Market The decentralized nft auction market, which supports nft auctions from different blockchain networks through inter-chain auctions, creates a new scenario of circulation between NFT chains Max Supply: 10.000.000.000 Resource: https://darwinia.network/
