PolkaBridge

PolkaBridge is a cross-chain decentralized finance protocol currently running on Ethereum, with PBR as an ERC-20 token and an ecosystem planned across Ethereum, Polygon, BSC, Harmony, Moonbeam and Polkadot. The protocol consists of three modules: the cross-chain AMM charges 0.2% per swap as designed in its whitepaper, with 80% going to liquidity providers and 20% routed to an address that buys back and burns PBR, forming a deflationary farming loop; the Launchpad lets users who stake PBR take part in initial offerings of new projects; and farming plus staking modules round out the stack, with PBR doubling as collateral for network activity and a governance credential.

In market terms, PBR has a total supply of about 74.89 million tokens, traded near $0.0008 in October 2026 with a market capitalization in the tens of thousands of dollars and recordable turnover close to zero, down more than 99% from a high around $3.91 in November 2021 and hitting a low near $0.00015 in February 2026. The protocol is now mainly recorded by data platforms as a long-tail cross-chain DeFi sample, with on-chain swap and launchpad activity at extremely low levels.
