Vesper provides a platform for easy-to-use Decentralized Finance (DeFi) products. Vesper's DeFi products deliver ease-of-use in achieving your crypto-finance objectives. The Vesper token (VSP) is the core economic engine that facilitates the building and expansion of Vesper’s capabilities and its community.
The Vesper project rests on three pillars:
Vesper Products: At launch, Vesper offers a variety of interest-yielding "Grow Pools" that enable users to passively increase their crypto holdings by simply selecting the desired aggressiveness of their strategy and the digital asset held. The Vesper Grow Pools represent the first product on the Vesper platform. More will be developed and presented over time.
Vesper Token: VSP incentivizes participation, facilitates governance, and catalyzes user contribution. Users earn VSP through pool participation and, later, participating in Vesper's continuous improvement.
Vesper Community: Vesper is building a user community that sustains and grows the product portfolio, facilitates progressive decentralization, and enables users to build new products while earning a share of that product's fees.
The bug bounty program is focused around Vesper’s smart contracts and the prevention of loss of user funds. It has its rewards for critical vulnerability disclosures matched by the Armor Alliance Bug Bounty Challenge.
Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.
Rewards for critical bug reports are further capped at 10% of economic damage.
Payouts are handled by the Vesper team directly and are denominated in USD for payouts up to USD 100 000 and are done in VSP. For payouts above USD 100 000, the remaining amount is covered by the Armor Alliance Bug Bounty Challenge and is paid in ARMOR with a vesting period of up to 24 months.

Out of Scope & Rules
The following vulnerabilities are excluded from the rewards for this bug bounty program:
- Attacks that the reporter has already exploited themselves, leading to damage
- Attacks requiring access to leaked keys/credentials
- Attacks requiring access to privileged addresses (governance, strategist)
- Incorrect data supplied by third party oracles
- Not to exclude oracle manipulation/flash loan attacks
- Basic economic governance attacks (e.g. 51% attack)
- Lack of liquidity
- Best practice critiques
- Sybil attacks
The following activities are prohibited by bug bounty program:
- Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
- Any testing with pricing oracles or third party smart contracts
- Attempting phishing or other social engineering attacks against our employees and/or customers
- Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
- Any denial of service attacks
- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
