What Is PBR？
PolkaBridge is a decentralized cross-chain protocol designed to act as the primary bridge between Polkadot and other blockchains. It will also introduce supporting DeFi features, to complement the bridging services. It currently operates on the Ethereum blockchain and is planning to migrate to the Polkadot blockchain, in the near future. Other chains support would be added in the future, as per the requirements. The PBR token is the native asset of the PolkaBridge project. It exists primarily as a ERC-20 token on the Ethereum blockchain for now, but will be introduced on the Polkadot blockchain soon.
