ADD: WEWESwap Migration V1

[jpthor]

Overview

1) Migration contract 2) Simple LM Contract 3) Farming Contract

Migration Contract

• Move LP NFT from WEWE-WETH to WEWE-USDC on BASE.UNIv3

• Collect Rewards (WEWE+WETH)

• Sell WETH to USDC (user now has WEWE-USDC)

• Deposit in LM Contract

• LM Contract does the new Deposit as Owner

• Refund the balance that can't be deposited in the band

LM Contract

• 1 infinity band, no rebalancing
• should support dual-token (WEWE+USDC) + single-token deposits (WEWE OR USDC)
• migration should use dual-token
• Everyone else later, will use single-token deposits

Tokenised Membership

(ERC20 + ERC777)

• approveAndCall() // you can stake in 1 transaction
• transferAndCall()

Yield Collection

• LM contract accrues the WEWE, USDC yields

• anyone can call collectFees(), which sells WEWE fees to USDC and bring back to LM Contract

• let this function be public for a bot to call, or anyone, and wrap this when someone collects their yield.

• LM.claimFees() is when a user gets their share of the USDC yield

• LM.claimFees() wraps LM.collectFees() which grabs the total Vault yield

• So this way someone collecting their USDC will collect the standby fees for everyone else (a perpetual loop)

• claimFees() needs to use Masterchef rewardDebt function https://dev.to/heymarkkop/understanding-sushiswaps-masterchef-staking-rewards-1m6f

Farming Contract && Token Minter (CHAOS)

Rewards Token Minter has in-built emission schedule, which mints itself along a Reward tokens are claimed inside itself

Owner Functions 1) Set the global Emission Rate tokensPerBlock (set to 0 to turn off) 2) Whitelist LM Contract Vault Tokens (adds to array) 3) Set weights per LM Contract (for any vault)

examples
setVaultWeight(index, weight) onlyOwner
[1, 1, 1] sum is 3, so a vault is ⅓ = 33%
[2, 0, 1], sum is 3, first vault is ⅔, second vault is disabled, 3rd vault is ⅓

setting a weight to 0 effectively disables it

1) CHAOS Rewards ERC20 minter has a collectEmissions(pool) public anyone can mint the new allowed supply (to itself) 2) Users staked Pool Tokens in the Farming Contract 3) Users also call collectEmissions(pool) to get the entitled REWARDS PER POOL
