Technology Recap:


  • Binance is working to integrate the Lightning Network for deposits and withdrawals. 

  • Thomas Voegtlin posted to the Lightning Dev mailing list suggesting BOLT11 invoices be extended to optionally allow a receiver to request two separate payments from a spender. Each payment would have a separate secret and amount.

  • A proposal was published to upgrade Polygon Proof-of-Stake (PoS) to a zkEVM (zero-knowledge Ethereum Virtual Machine) validium. This would be a first-of-its-kind decentralized ZK layer-2.

  • EigenLayer announces the deployment of Stage-1 Eigen on Ethereum mainnet. This marks a major milestone in their mission to create a permissionless environment for innovation.

  • L2Beat unveils “Stages”, a maturity ranking for layer-2 projects. This builds off of Vitalik Buterin’s view on milestones for rollups. 

  • ARPA Network’s mainnet is now live on Ethereum! ARPA allows dApp developers to use a random number generator, multi-party computation tools, decentralized voting systems, and more directly via ARPA. 

  • Reserve is deepening its involvement into Curve Finance by making a $20M investment in their governance ecosystem.

Hacks | Vulnerabilities | Exploits:

  • On June 16, 2023, Pawnfi was attacked on Ethereum in a flurry of transactions due to failing to verify whether the NFT had actually been transferred when users used a specified NFT as collateral for borrowing. 

  • On June 17th, 2023, Midas Capital was exploited on BSC which resulted in a loss of ~$600K. Midas is a fork of Compound and the attack is very similar to the vulnerabilities found in Hundred Finance and Silo Finance that were disclosed on June 17th as well. The root cause is a rounding issue in the lending protocol.
