[SIPS-149] Upcoming Real Yield USD (Arbitrum deployment) Liquidity Mining Incentives Proposal

This forum post is to discuss the upcoming Governance proposal for liquidity incentives on the Real Yield ETH Cellar (Arbitrum deployment), which will go up for vote on Monday, June 24, 2024.


This proposal is intended to authorize a one-time transfer of 50,000 SOMM from the community pool to the CellarStaking contract, which will be used to further incentivize cellar depositors on Arbitrum. This program will distribute the authorized amount of tokens over a period of 30 days, starting at the date this proposal passes and is enacted. The total amount of tokens for the proposed program represents 0.044% of the tokens in the community pool.

These funds will be used to further incentivize participation in the Real Yield USD (Arbitrum deployment) Cellar. Since launching in February, the vault has attracted ~$2.5M in TVL. Any future incentive program is outside the scope of this governance action and will require a new proposal.

The tokens prescribed by the program will be distributed pro rata to users on Arbitrum who elect to bond RYUSD in Sommelier’s staking contract. The CellarStaking smart contract (cellar-staking/CellarStaking.sol at main · PeggyJV/cellar-staking · GitHub) governs the bonding of RYUSD and the distribution of the tokens reserved for SOMM rewards. Pro rata allocation is determined based on share of the pool, where that share is equal to the amount of the user’s RYUSD tokens deposited, multiplied by a “boost” determined by the amount of time those cellar shares are locked for. Shares receive a 10% boost by locking for 7 days, a 30% boost for locking for 14 days, and a 50% boost for locking for 21 days.

This smart contract, 0x623987D3CC0d504782bc99BBAc7965fe54917D7D, is based on canonical staking conventions used across the Ethereum Virtual Machine, principally the Synthetix staking rewards contract, originally developed in 2018. Variations of this code have secured billions of dollars of rewards across various EVM-compatible blockchains. The CellarStaking smart contract has been audited by Macro, with the audit available here: cellar-contracts/Macro_Cellar_CellarStaking_07_2022.pdf at main · PeggyJV/cellar-contracts · GitHub.

A multisig on Arbitrum, 0x85974Dc8978De3Ba84E8B1D0CC67b54F40028Eda, has administrative powers over the staking contract and is able to perform the following actions:

Schedule a certain amount of tokens owned by the contract for distribution (via notifyRewardAmount)

Set the duration of future rewards programs (via setRewardsDuration)

Set the minimum deposit in RYETH tokens in order to participate in the rewards program (via setMinimumDeposit)

Pause and unpause bonding operations in emergency scenarios (via setPaused)

Trigger a one-time emergency shutdown on the contract, which stops new reward accumulation and allows all depositors to withdraw their assets immediately, disregarding unbonding times (via emergencyStop).

The multisig is currently composed of a mix of early developers on the Sommelier Chain and protocol, Ethereum smart contract developers, and cellar strategists:

Zaki Manian
Kristi Polsdam
Joseph Terrigno
Stephanie Vaughan
Sunand Raghupathi
Crispy Mangoes
Josh Kessler

This proposal, if accepted, will spend 50,000 SOMM from the community pool in order to fund the CellarStaking contract according to the parameters of this proposal. The multisig shall be responsible for enacting the program according to the parameters of this proposal once the requisite SOMM tokens are funded by the validators.
