• Continued working on finalizing the MELD Bridge in the webapp,
• Configured bridging functionality to work with ChainPort in testnet for testing purposes,
• Carried out ChainPort signature reimplementation and deployed to PRTOD,
• Improved UI for the dedicated Yield Boost and Bank Manager NFT rewards components in the Supply & Borrow,
• Updated the main overview interface to show Banker Rewards information based on their multipliers (standard vs golden),
