MELD Dev Diary 85

Hey there! Welcome to our Dev Diaries. This is where we give you a peek behind the curtain to see how we’re making MELDapp even better. So, what have we been up to in the last week?

MELDapp Web:

• Continued working on the new MELD’s native Bridge implementation,
• Deployed improved NFT interface with fixed empty state and support for NFT ERC-1155 standard in DEV environment for the internal QA,
• Worked on a new concept of tracking an asset as “protected from liquidation” in the Supply & Borrow,
• Carried on with front-end development of the Yield Boost and MELD NFT Bank Managers’ YB multipliers when locked with a supplied or borrowed position.

MELDapp Mobile:

• Focused on fine-tuning the app before submission to the App Store:

🛠️ removed remainings of the MELD API v1 from the project,
🛠️ when sending a crypto asset the ‘next’ button should match asset’s main color theme,
🛠️ fixed app crashing when Crypto Wallet selected with empty balance (no assets in the wallet),
🛠️ improved the way MELD asset page looks like for empty state (zero balance),
🛠️ fixed issues when inputting a custom handle in the onboarding flow,
🛠️ based on community’s feedback the fast scrolling through transactions history has been brought back,
🛠️ fixed app hard resetting upon completion of the Forgot Passcode flow,

• Continued with intense development of the FIAT currencies user interface, on/off-ramp, bank account support and associated send/receive flows.
