MELD Dev Diary 58

Welcome! In our Dev Diaries, we delve into the continuous advancements and meticulous fine-tuning of the MELDapp. Here is last week’s progress:

• Added Receive flow for NFTs (from now on ASSETS and NFTs have separate SEND & RECEIVE flows),
• Fixed crypto amounts formatting & rounding rules,
• Fixed gas calculation on native tokens on EVM,
• Multiple UI fixes and tweaks (e.g. market info widget font sizes, wrong icons for tokens in the RECEIVE flow, ‘transactions in queue’ copy change and more),
• Deployed gMELD to MELD wrapping and MELD to gMELD unwrapping behind friends & family addresses whitelist (launching to public soon),
