[ARFC] aAMPL Second Distribution

Simple summary

A proposal for a follow-up distribution of 758’000 in stablecoins from the Aave Collector to allow full withdrawals by aAMPL suppliers to Aave v2 Ethereum, the consequence of the problem detected at the end of 2023.


In December 2023, a problem was detected on the AMPL custom reserve on Aave v2 Ethereum, causing an unexpected inflation of AMPL-related balances and supply, not following the intended design by the Ampleforth team.

After further analysis and remediation strategy, the Aave governance approved and executed a proposal on April 17th to provide approximately 300’000 USDC for aAMPL holders to claim. This was designed as an initial and interim distribution, with the sole objective of providing liquidity for users affected as soon as possible. Meanwhile, the service provider of the Aave DAO and the Ampleforth team completed further analysis for a final distribution proposal; this one.


To fully understand the problem at hand and the rationale of this distribution, we recommend mandatorily reading its specification on the Aave forum AMPL problem on Aave v2 Ethereum - #155 by ChaosLabs, to make an informed decision.

In summary, this proposal recommends making claimable 758’000 stablecoins from the Aave Ethereum Collector, in addition to the already distributed 300’000 USDC, making a total of approximately $1,057,677.

Some key points output of the analysis are:

  • Decisions when doing the analysis have been made to favor aAMPL holders, whenever it was subjective generally, but always trying to maintain objectivity on the expected dynamics of AMPL on Aave.
  • Real returns of supplied AMPL on Aave have been recalculated from the freezing period until the expected execution time of the proposal (beginning of May 2024). This approach, compared to calculating from market inception, preserves four times more AMPL for users, maximizing welfare for AMPL suppliers.
  • The previous analysis resulted in identifying a claimable amount of 351,579 AMPL as of December 16th, 2023, after rectifying highly evident artificial inflation within the 764,303 aAMPL total supply. As a reference point, debt levels were observed to be at 42,847 AMPL during that period.
    As further compensation for the time passed since December during which funds were not withdrawable, the latest on-chain rate is applicable on the 351’579 AMPL: 256% compounding for more than 4 months, which results in a total of 882’869 AMPL, or $1,057,677.
  • Uniform 100% utilization from 16th December 2023 to the beginning of May 2024 is considered, disregarding the underlying rebases of AMPL. This also tries to heavily increase the amount received by aAMPL holders, as once again, debt levels are currently just 72K vAMPL, compared to the much greater compensation amount.
  • Pricing claims at $1.198 price per AMPL, despite the price falling below and negative rebases accruing on the aAMPL supply since.
  • Any holding by the Aave Collector contract is not included in the compensation, to increase the amount received by other aAMPL holders.
  • Interest generated from the 300’000 available on 17th April to withdraw is discounted, as those funds are fully claimable by users.
  • Minor adjustments may occur during the AIP stage but will not significantly impact the compensation amount.

The Ampleforth team agreed to compensate 40% of the total after proposal execution, as stated on https://governance.aave.com/t/ampl-problem-on-aave-v2-ethereum/15886/128, which will be done after Aave fully approves this distribution.

Regarding the technical details, the proposal will:

  • Initiate a distribution campaign of the 758’000 stablecoins (or any other stablecoin recommended by Aave treasury service providers) on the Merkle platform, which has already been used for the initial interim distribution.
  • Optionally, authorize any further technical update on the AMPL v2 Ethereum reserve to be done if required on the AIP stage.


This proposal was created by BGD Labs and Chaos Labs within their respective engagements for technical services with the Aave DAO. Its execution will depend exclusively on the decentralized Aave governance approving it.

Next Steps

  1. In parallel with this Snapshot vote, preparing the final technical details of the AIP.
  2. If the Snapshot outcome is YES, escalate to the on-chain AIP stage.

With the description of the distribution done already 3 days ago leaving appropriate time for discussion and awareness of the community, in coordination with Chaos Labs we have created the ARFC Snapshot.

Voting will start in approximately 24 hours, participate :ghost:



After the positive outcome on the ARFC Snapshot, and following the governance procedures, we have created a on-chain AIP for this second distribution for aAMPL holders, denominated in aUSDC (USDC on Aave v3), following the recommendations of finance service providers.

It is possible for users to check in advance in the document HERE, and similar as with the initial distribution, we will share the Merkle link to claim once the proposal gets executed.
