AMPL is the first rebasing currency and a key DeFi building block for denominating stable contracts. The AMPL protocol adjusts total supply daily based on market conditions, transferring volatility from price to supply. Like Bitcoin, AMPL’s elastic supply policy does not rely on traditional banks or lenders of last resort. Because of this unique approach, AMPL can be used as a true unit of account to denominate smart contracts.
The aAMPL token, a custom aToken on Aave, is planned to be entered into polling with the goal of being integrated into the Aave ecosystem, and was formally submitted as AIP37.
Further resources regarding Ampleforth can be found on their website, https://www.ampleforth.org/.
The bug bounty program is focused around its smart contracts and is mostly concerned with:
- The loss of user AMPL deposits
- Theft of unclaimed yield
- Freezing of AMPL on Aave for 1 hour or longer
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.
Only vulnerabilities that are directly affecting aAMPL and the yield generated from aAMPL are considered under this bug bounty program. For example, if yield can be stolen from staking of other aTokens, they will not be considered for a reward.
Payouts up to USD 50 000 are handled by the Ampleforth team directly and are denominated in USD. However, payouts are done in ETH, USDT, USDC, or AMPL, at the discretion of the team.
- USD $50,000
- USD $10,000
