veSync Protocol Update — Epoch1-3

4 min readJun 6, 2023

veSync celebrated its successful launch on May 15 and has since seamlessly operated through three epochs. As we stand on the cusp of concluding Epoch 3 and embark on the journey toward Epoch 4, it’s time to reflect upon and share the milestones we have reached and the strides we have taken.

Application Update: Statistics Banner, Rainbowkit, and UI Improvement

We have added a protocol statistics banner at the top of the application. This banner displays the following data: protocol TVL, real-time price of governance token ($VS), market cap, circulating supply, and countdown to the next epoch. By providing this data, we hope to help you make informed investment decisions and not miss any voting opportunities during each epoch.We are proud to introduce the new and modern Rainbowkit, replacing the old and laggy wallet connector that only supported four kinds of wallets. Rainbowkit is more lightweight and visually appealing.

Additionally, the dev team has fully refactored the smart contract-interacting code and fixed known bugs. On the swapping page, users can now swap “Half” or “Max” of their token balance. We believe that these updates will provide users with a better UI experience on veSync.

veSync Ongoing security auditing with Zokyo

We have invited Zokyo as our auditing partner to conduct a thorough and secure audit. The veSync smart contracts code has passed auditing three times, with the first two being Solidity auditing from PeckShield and Velodrome auditing from Code4rena. The third and final audit is being conducted by Zokyo, with an estimated finishing date at the end of June.

We believe that this security audit will make veSync more secure and ensure that all user funds are safe.

Zokyo is a web3 security firm that specializes in smart contract auditing (Solidity, Move, Rust, etc.), penetration testing, token economic design and review. They have audited LayerZero, Umami Finance, Polygon, 1inch, RDNT Protocol, and other DeFi protocols, and have a good reputation in the industry.

veSync Stat Dashboard Live on Sentio

-> Link to Dashboard

About Sentio: Sentio is an end-to-end observability platform that helps you gain insights, secure assets, and troubleshoot transactions for your decentralized applications.

Currently, Dune does not support zkSync era, so we had to find our own solution to display the protocol data to users. Clear protocol statistics, including token holders, locking ratio, swap volume, and TVL in different pools, can help veSync investors understand where we are. We collaborated with Sentio to fetch the zkSync Era on-chain data and turn it into readable and user-friendly dashboards. Additionally, we are working on a series of data APIs for developers. With these APIs, developers can easily build veSync stat bots on Telegram and Discord.

veSync all Smart Contracts are Verified on zkSync Explorer

Smart contract verification and open-source are important for security and safety, but they can be challenging in the zkSync era. This is because zkSync is not 100% EVM-compatible, and there is currently a bug in the verification plugin.

Fortunately, the veSync team has fixed the bug, found a verification solution, and completed the contract verification work. The smart contract includes all functional smart contracts and liquidity pool contracts created by the factory.

Partner with TProtocol, the first LSD solution for stablecoin

The zkSync official bridge portal for wTBT (a token from TProtocol) is now live. Users can bridge wTBT from Ethereum to zkSync and then provide liquidity to the wTBT-USDC pool on veSync to enjoy triple yield rewards (wTBT interests, TProtocol airdrop, and vsSync reward).

About TProtocol: TProtocol is the first DeFi composable LSD solution for stablecoins and the next generation DeFi infrastructure.

veSync Integration: Firebird & Impermax

veSync has now integrated with Impermax and Firebird.

Firebird is a DEX aggregator that is fully integrated with veSync. Users can swap $VS tokens on Firebird. Additionally, a large amount of ETH or USDC swapping with Firebird on the zkSync era will use liquidity pools on veSync.

Impermax is a decentralized lending protocol. Users can lend, borrow $VS tokens, and engage in leverage yield farming on veSync.
