The Polkadot Treasury 1439 referendum proposal co-sponsored by Bifrost and Hyperbridge was passed yesterday. The proposal aims to allocate 3.50 million US dollars (about 25 million yuan) in the top DEX cooperation in the Ethereum, Arbitrum, Base, BSC blockchain ecosystem for DOT and vDOT (DOT LST) to establish liquidity. Developers can use the liquidity, Hyperbridge cross-chain and Bifrost SLPx SDK to freely carry out cross-chain combination and application development around DOT/vDOT in the above blockchain ecosystem, and share the proceeds to take advantage of Polkadot's cross-chain interoperability.
