MELD Dev Diary 92

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

MELDapp Web:

• Deployed the multicall functionality to DEV env for QA and testing (ability to submit a batch transaction of multiple actions such as claiming / compounding / repaying a loan using Yield Boost rewards),
• Implemented compounding (claim rewards and supply) and repay logic,
• Prepared the PROD environment for the new deployment by ChainPort,
• Implemented an improved cost structure breakdown menu for the standalone MELD bridge,
• Experimented with thirdweb/WAGMI integration in the MELDapp,
• Added error handling and coverage for several edge-cases in the standalone bridge UI (still available for public testing at https://testnet-bridge.meld.com/).

MELDapp Mobile:

• C2C Exchange: Improved error handling when the current ticker is not available,
• C2C Exchange: Fixed swap endpoint parsing error,
• C2C Exchange: Fixed max button decimals error,
• C2C Exchange: Fixed missing icons for Tether and PancakeSwap tokens,
• C2C Exchange: Fixed total amount calculation,
• C2C Exchange: Improved unit test coverage,
• C2C Exchange: Avoided logging/reporting unnecessary errors on Sentry,
• Finished unit test coverage improvements on our internal FIAT Payments module,
• Updated Instabug dependency to the latest version across all modules,
• Fixed NFTs endpoint parsing.

Solidity | Backend:

• Implemented GoGoPool adapter for Yield Boost rewards farming,
• Tested Aave adapter with Ethereum fork and fixed bugs,
• Reworked events of MeldFarmingManager and adapters,
• Implemented RescueTokens functionality for Yield Adapters,
• Reviewed preliminary audit reports of the Supply & Borrow protocol,
• Updated destination token name when scanning completed request in bridge service,
• Updated Cardano contract to prevent paying to locker without datum,
• Read manager UTXO from both reference inputs and outputs in a Cardano transaction,
• Got locker input value by script hash instead of addresses,
• Updated bridge subgraphs to track Yield Boost farming manager and adapter contracts,
• Implemented cronjob to run auto rebalancing,
• Added DB schema for token allocation on each network,
• Fixed wrong timestamp while tracking oracle in subgraph,
• Connected EVM wallets to admin frontend,
• Generated typescript client from open API for frontend code,
• Added the excludeFee parameter to the bridge/fee API,
• Brainstormed the implementation for yield boost logic,
• Set up the admin builder and resolved version conflicts,
• Implemented the yield page, integrating Lucid and using Cardano to connect Cardano wallet,
• Deployed new EVM contracts and addressed and fixed the receiver contract deployment issues,
• Tested the newly deployed version, identified, and investigated the missing role issue,
• Implemented update manager datum API,
• Deployed new Cardano contract for DEV env,
• Rebalanced API on Cardano,
• Filtered UTXO has datum.

Infrastructure:

• Disabled meld.fi container build and pushed to AWS,
• Enabled meld.fi container build and pushed to GCP,
• Started configuring meld.fi service in k8s,
• Deployed meld.fi to k8s cluster,
• Fixed minor issues with k8s load balancer,
• Changed meld.fi DNS record to k8s deployment,
• Modified graph-node tasks and deployed changes,
• Made final changes to meld-fi k8s deployment and merged changes,
• Worked on staking rewards migration to k8s,
• Migrated staking reward setter from AWS to GKE,
• Configured build and push GitHub actions pipeline for staking-reward-setter.

We deeply appreciate your steadfast support, which remains a cornerstone for us. Your feedback holds immeasurable worth as we persist in our pursuit of innovating and perfecting the MELDapp. Stay tuned for a series of forthcoming updates in the weeks ahead.
