MELD Dev Diary 02

Lending & borrowing
MVP design

Finalized first release features set:

• lending and borrowing,
• CDP liquidation including yield level low to no risk;
• LP NFTs are being developed. Supply NFTs will be used to act as a receipt and mark liquidity providing positions in the protocol.

Writing the functional specifications for architecture

MELD Staking & Vesting

• Fixed double satisfaction issue (we now only allow a single vesting position withdrawal per transaction).
• Deployed vesting and staking to the preview testnet including contract and config updates.

Akamon Bridge

• Completed integration tests, fixed configuration conflicts and broken CI issue so we can deploy Akamon Beta to preview testnet next week.

Infrastructure

Identified and deployed bug fixes on mainnet infrastructure:

• Failure to create 6-month staking positions
• Unable to send assets (ADA, MELD tokens) via the MELDapp
• Node sockets which connect our API, Indexer, DB-sync, and other servicies to cardano-node keeps crashing.

The team has re-started all services and is testing different solutions to make the system more stable.

• Deployed newest versions of Cardano node and db-sync (cardano-node:1.35.3, cardano-db-sync:13.0.4) on mainnet.
• Increased storage sizes on both EC2 instance and on RDS storage.

Reconfigured the following components of Cardano stack and MELD stack for preview network:

• Staking/Vesting: cardano-node, cardano-db-sync, meld-api, meld-index.
• Akamon: cardano-node, polygon-node, ipfs, graph-node, akamon-api, akamon-cardano-index, akamon-node.
