Wu said that the referendum proposal for Polkadot Treasury No. 1439, co-sponsored by Bifrost and Hyperbridge, has been approved. The proposal aims to allocate $3.5 million to DEX collaborations in the Ethereum, Arbitrum, Base and BSC blockchain ecosystems to provide liquidity for DOT and vDOT (DOT LST). Developers can carry out cross-chain combination and application development around DOT/vDOT in the above-mentioned blockchain ecosystem based on this liquidity, combined with Hyperbridge's cross-chain function and Bifrost's SLPx SDK, and share the benefits.
