PDP 33: Bribe centric config set

Posted on behalf of the mStable ProtocolDAO

Simple Summary

It is proposed to modify system configuration for a 6 week period, specifically the govFee and RevenueRecipient for mUSD, to redirect a predefined percentage of system revenue to Votium in order to capitalise on the under-utilised vote bribing market and generate circular effects for mUSD.


This proposal is based on the following pieces of information:

  • Curve emits huge rewards each week, distributed proportionately to votes on their gauges
  • Current mStable yield farming methods are inefficient and produce a low ROI for the protocol
  • It is possible to “bribe” veCRV/cvxCRV voters to vote for a specific gauge. This effectively allows for very high leveraged yield farming opportunities due to the huge CRV emission

mStable trialed this for one week with a $9k bribe through https://votium.app/ (targeting all cvxCRV votes) and seen mUSD supply in the mUSD-3Crv pool increase from 1.2 - 14m.

This proposal seeks to provide a set of experimental configurations that allow mStable to fully capitalise on this opportunity. This will be done in coordination with a large initial injection of $MTA, to ensure that the initial TVL is high and this configuration has sufficient network effects to take effect.


As defined in the abstract, current mStable yield farming methods are inefficient. This proposal seeks to generate circular effects for mUSD without the use of the existing $MTA emission.

mStable is in a unique position, because when the mUSD supply rises, so does the system revenue. The system can then use this revenue (collected in $mUSD) to buy $MTA and to fund with it the next batch of bribes. This causes a positive feedback loop that can grow $mUSD supply (until the market becomes 3-4x more saturated, however even after this point, the bribes should still cause the TVL to float high).

  • Having higher system revenue will have knock on effects to SAVE, increasing the TVL and user base there independently
  • This should have positive effects on the $MTA price as our overall network effects will dramatically increase

The bribe market is still unsaturated/inefficient. This is changing and is likely to get more saturated in the coming weeks, so capitalising asap is important.


A new IRevenueRecipient will be deployed, with the following features:

  • the ability to deposit $MTA into Votium, once per two weeks
  • configurable bribePct variable, that determines the % of $mUSD held to be deposited into a child IRevenueRecipient (could be used for sending surplus bribe $ to for example buy CVX for longer term farming)
  • configurable IRevenueRecipient, initially set to be the existing Buy & Make pool depositor

The following settings will be changed:

  • setSavingsRate will be called with 5e17 on SavingsManager, setting the percentage of system revenue set aside to be 50% (note: this requires an upgrade to SavingsManager)
  • setRevenueRecipient will be called, setting the mUSD Revenue Recipient to be the above
  • Swap and Redemption fee on mUSD will be changed to 4e14 and 20e14 respectively
  • Caps will be removed on the Liquidator for the mUSD integrations (note: there is currently less than the existing cap available, so this in effect has no change)

During this period, mUSD system revenue from Feeder Pools and Polygon will also flow to the new IRevenueRecipient by default.

Should the parameter set seem to be operating poorly during this period, resulting in a net negative revenue for SAVE (i.e. mUSD TVL goes below $60m), the savingsRate will be updated with a relative amount, between 10% (existing) and 50% (proposed).

Start date will be immediately following successful resolution of this proposal, and last for 6 weeks, after which time the settings will be reverted.

Next Steps

Pending no significant changes to its content, this proposal will be taken to snapshot vote on Monday, 18th October 2021. Voting will be open for a 5 days window to give adequate time for a concurrent discussion. Governors can change their vote at any time should the discussion sway their decision. We look forward to hearing what MTA token holders have to say and seeing how they cast their votes.


This proposal is very opportune now. I would like to ask for everyone’s understanding that this proposal is posted on such short notice because of the sensitive timing and coordination that was required to make this happen. We will still put the voting up for the whole 5 days as we usually do.


I think this is really interesting - great idea. Very much supportive


Totally in support of this. Curve inflation is huge and the current mechanisms to distribute it through gauges is still on its early days i.e bribing is still cheap
The extra TVL / amount bribed ratio speaks for itself.

The proposal was amended in the following way:

Added buy $MTA:
The system can then use this revenue (collected in $mUSD ) to buy $MTA and to fund with it the next batch of bribes.

Changed $mUSD to $MTA:
the ability to deposit $MTA into Votium, once per two weeks

Vote is live: Snapshot

Definitely a big fan of this, as it is taking a very opportunistic stance on this whole bribing take, and we’re still early with the deployment for this, so could see this potentially be huge for the ecosystem and especially savers!

I don’t see any Votium bribes since the original trial of 14,400 MTA to Votium arount October 5th. Are the revenues still being aggregated and plan to be used in the near future?

I think this might have been answered in Discord already? If not here is the address that supplied the MTA Address 0xd0f0f590585384af7ab420be1cfb3a3f8a82d775 | Etherscan
