Band Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. Blockchains are great at immutable storage and deterministic, verifiable computations. However, they cannot access trusted real-world information available outside their networks. Band Protocol enhances smart contract functionalities by granting them access to reliable data without any central points of failure. Decentralized Finance applications need price feeds on token swap and loan collateralization process. With Band Protocol’s built-in price oracle, developers can build DeFi with an absolute peace of mind that the price feeds they’re using are robust and tamper-proof. BandChain is designed to be compatible with all smart contract platforms and blockchain development frameworks. In a trustless and decentralized manner, BandChain does all the heavy lifting jobs of pulling data from external sources, aggregating, and packaging them.

Scale your DApp to Polkadot with Acala, an Ethereum-compatible smart contract platform optimized for DeFi. Acala is the decentralized finance network and liquidity hub of Polkadot. It’s a layer-1 smart contract platform that’s scalable, Ethereum-compatible, and optimized for DeFi with built-in liquidity and ready-made financial applications. With its trustless exchange, decentralized stablecoin (aUSD), DOT Liquid Staking (LDOT), and EVM+, Acala lets developers access the best of Ethereum and the full power of substrate. Access DOT-based assets and derivatives, Polkadot-native decentralized stablecoin, Polkadot ecosystem assets, and cross-chain assets from Bitcoin, Ethereum and beyond. Acala’s chain is customized for DeFi and can continue to upgrade without forks to integrate new features requested from developers. For example, on-chain ‘keepers’ automate protocol execution to better manage risks and improve user experience, or transaction fees payable with virtually any token.
