Description

Build contract or set of contracts to allow projects to manage liquidity mining reward distribution. The contracts must at a minimum be able to do the following:

• Accept an LP token for lockup
• Accept a separate governance token to be rewarded
• Distribute governance token periodically to users based on their share of total LP tokens locked. This may accumulate for them to claim.
• Allow users to claim rewards
• Optional: Allow the contract instantiator to create multiple reward tiers based on lockup time (e.g., 100 tokens per block for 1 day lockup, 200 tokens per block for 1 month lockup, etc)
• Allow contract creators to specify whether it is a timed lockup or an unlocking time similar to how Osmosis handles lockup

Context

Liquidity mining is the process of distributing ownership of a protocol as a reward to users who provide assets (“liquidity providers”, LPs) to the protocol or to facilitate trade on a decentralized exchange.

The Osmosis chain on Cosmos has enabled this for a limited set of cases. The Osmosis protocol distributes its native token OSMO to LPs of specific AMM pools to bootstrap liquidity and allow trading of those tokens. To receive these distributions, users must lock their liquidity tokens and agree to an unlocking period (Osmosis allows 1 day, 7 days, and 14 days as their unlocking period).

The goal of this bounty is to solve this problem more generally and to allow projects to offer liquidity mining rewards to LPs in major Cosmos DEXs (Osmosis and Gravity DEX to start) with flexible structures.

Acceptance Criteria

• Functionality present in the description is met
• Local demonstration which locks an LP token from the Agoric AMM is shown
