Assurance and Risk

PreviousAuditNextRoadmap

Last updated 1 year ago

The VBUSD code contains the following assurances:

  • Admins cannot arbitrarily mint VBUSD

  • wstETH-ETH swaps are limited to a certain slippage

  • Multi-step redemption prevents reentrancy attacks

  • Multiple in place to ensure full collateralization

  • Reserves can be rescued from the contract in case of a bug

In addition:

  • The project is fully decentralized (no centralized exchange involvement)

  • Project-specific Hardhat Solidity testing scripts have been created and used

  • Many applied tests of the contracts have also been done and passed

  • The consists of very ethical and all-around cool people

The protocol also has systemic risks of which all users should be aware:

  • GMX Insolvency: If GMX traders win overall, or if the GMX protocol is exploited, their asset vault could be drained, and we could be unable to redeem our short position for full value

  • Slippage: The protocol is required to complete swaps during certain operations, which may result in slippage if the liquidity is insufficient. However, we only swap on major pairs such as WETH-wstETH, on the DEXs with the deepest liquidity.

  • Changes in leveraged trading market participation: Funding fees could turn negative, and we could be charged maintenance fees on our short. This would be a , as longs have traditionally been more popular than shorts

  • Extreme volatility: Excessive fluctuations in ETH price could result in repeated GMX position opening fees from , especially if the delay between short position closing and opening is longer than anticipated. However, it seems unlikely for significant losses to occur via this route, as we do not expect reinitialization to occur often, and it will only occur when ETH moves in the upward price direction.

  • Extreme network congestion: Gas fees could rise exponentially, resulting in fees that make it impractical to

  • VBUSD Technological risk: some aspect of the all-new DeFi primitive's code could be faulty

  • GMX technological risk: some aspect of the all-new GMX Synthetics code could be faulty

  • Team risk: The protocol could be halted if the team loses one or more key members. An orderly wind down would be conducted in that case.
