Infrastructure 🏗

Ethereum

• Eclipse launches mainnet for developers. Eclipse is the first SVM L2 on Ethereum, combining the best of Solana’s speed with Ethereum’s liquidity.

L2s

• Nimbus Eth2, the Nim implementation of the Ethereum Beacon Chain, released v24.7.0 with beacon API improvements and fixes.

Solana

• Tensor Protocol released the V2 versions of RESTful APIs, SDKs for both JS & Rust, and programs.

Security 👾

• Ackee Blockchain Security introduces the Solana Auditors Bootcamp 2024, the online bootcamp for Solana developers to learn to audit Solana programs and help secure the ecosystem.
• Solidity introduces the Underhanded Solidity Contest 2024, uncovering anti-patterns and loopholes in the Solidity language design and using them to hide malicious back doors within seemingly innocuous Solidity code.
• Astroport, a decentralized exchange, suffered a hack resulting in losses of roughly $6.4M.
• Convergence, a DeFi protocol based on Curve, suffered a $210K exploit due to a vulnerability in Convergence's CvxRewardDistributor contract.
• Dimitar Tsvetanov shares Chinmay Farkya’s article “The risks of EIP-712”, covering the key pitfalls and best practices to prevent signature replay across chains.

Bug Bounties 🐞

• Backpack, the crypto wallet and exchange, launched a bug bounty program on HackenProof with bounties of up to $100,000.

Product Launches 🚀

• Eclipse, the first SVM Layer2 network, has launched its mainnet for developers on Celestia. Eclipse is a Solana Virtual Machine that combines Solana’s speed with Ethereum’s liquidity.
• Elixir, a modular blockchain project focused on providing liquidity for decentralized orderbook exchanges, has rolled out its synthetic dollar ‘deUSD’ to challenge Ethena’s USDe.
• Movement, an Etherem L2 network, launches its public testnet with the MOVEDROP program. Users can get involved with the testnet and start completing quests.
• Echelon, the first lending protocol on Movement L2, is live on the testnet. Users can claim test tokens from the faucet and start testing on Echelon.
• Lava Network, a Cosmos appchain for blockchain RPC, launches its mainnet. Lava lets chains quickly attract, aggregate, and coordinate RPC providers by creating incentive pools.
