How do I earn Liquidity Mining Rewards?
To earn $UMA rewards, you need to Mint and LP your Synth Tokens.
Mint a Synth by depositing Collateral
Provide the Synth and the paired asset (usually the same as the collateral) as liquidity in the specified AMM pool.
How do you determine how much Collateral to split between Minting and LPing?
Decide how much collateral you want to deploy toward minting and LPing a synth. [totalInvestment]
Check what the current GCR of the synth you want to mint is. You can find this on the page where you mint synths.[GCR]
Check what the ratio of the AMM pool assets you will LP in and divide the ratio of the collateral by the ratio of the synth. [poolRatio]
A normal uniswap or sushiswap pool is 50/50 so this ratio would be 1
An 80/20 balancer pool with 80% synth and 20% collateral would be
0.2 / 0.8 = 0.25
Enter the above parameters into the following equation:
((GCR/ (CGR + poolRatio)) * totalInvestment).This gets you the total amount of collateral you should use to mint. Use the rest to pair with the synth in the AMM pool.
Do I need to maintain my Collateral Ratio?
While the GCR limits the amount of new synthetics that can be issued, this ratio does not have to be maintained in order to avoid liquidation. The collateral requirement for all synthetic assets is 1.25 — meaning that if your CR <1.25, a liquidator may terminate your position.
As long as your CR stays above 1.25, nothing will happen. You can increase your CR at any time by depositing more collateral into your position.
Can I close my uSTONKS position before expiry?
Yes, you can redeem your uSTONKS for your USDC collateral back at any time before expiry.
If you redeem all of your minted uSTONKS, you’ll receive your full USDC collateral back.
If you redeem a portion of your minted uSTONKS, you need to maintain a leftover position of at least 1 uSTONKS token. Your CR will be adjusted accordingly post redeeming uSTONKS.
For example, you deposit 8,400 USDC and mint 10 uSTONKS tokens.
- You can redeem 10 uSTONKS token at anytime and withdraw your full 8,400 USDC collateral back. The price of uSTONKS at the time of mint or withdraw doesn’t effect the amount of returned collateral.
- If you want redeem only 5 uSTONKS, you’ll receive 4,200 USDC in collateral back. Redeeming a portion of your uSTONKS will return you a collateral amount proportional to the amount of synths redeemed. Your CR will remain the same post-redeeming process.
I used all of my USDC to mint uSTONKS and now need some USDC to LP. What can I do?
No problem. You can just “redeem” excess uSTONKS and receive the USDC needed to LP with.
How do I manage my Collateral Ratio?
You may one day want to deposit additional collateral to your uSTONKS position to avoid liquidation. Or you may also want to withdraw excess collateral if the collateral ratio has moved in your favor.
You can withdraw excess collateral in one of two ways: “Instant Withdraw” or “Request Withdraw.”
Instant Withdraw
You can withdraw excess collateral from your uSTONKS immediately, so long as the resulting CR is at least as high as the GCR. This provides peace of mind that you won’t be liquidated after making this withdrawal.
Request Withdraw (for Advanced Users only)
If you want to withdraw enough USDC to bring your CR below the GCR, you can do so by requesting a withdrawal. This is a two part process: you first submit a withdrawal request to the uSTONKS smart contract that indicates the amount of collateral you wish to withdraw and the timestamp of the request.
During a two-hour period, the ecosystem checks to see if the withdrawal brings the CR below the Minimum Collateral Ratio (1.25.) If this happens, you will be liquidated.
If this process elapses without liquidation, you can withdraw collateral from your position up to the amount requested.
Please note that the “Request Withdraw” is for advanced users only. Please only use this option if you are very familiar with the UMA and Degenerative Finance interface and mechanism.
How can I cancel a pending “Request Withdrawal”?
You are able to cancel a withdrawal request. While this functionality is not available on our UI (but will be in our Degenerative Finance V2 update!) you can call the action on Etherscan:
1. Go to the uSTONKS EMP contract on Etherscan: https://etherscan.io/address/0x4F1424Cef6AcE40c0ae4fc64d74B734f1eAF153C#writeContract
2. Navigate to the contract tab and click on “Write Contract.”
3. Click on “Connect to Web3” and connect your wallet (Metamask or Wallet Connect, for example.)
4. Click on “Cancel Withdrawal” and then click “Write.”
5. Follow prompts to sign and send transaction with your Web3 wallet. If you are worried about liquidation, use a normal or fast gas price.
6. Wait for transaction to be mined.
What happens at expiry?
At expiry, uSTONKS settles at the NYSE and NASDAQ prices of the underlying ticker assets.
If you purchased uSTONKS on Uniswap, you can let the token expire and settle your uSTONKS at the price of the underlying collateral (uSTONKS price (at expiry)*number of uSTONKS held)
If you minted uSTONKS and the position is still open at expiry the contract will calculate the value of the tokens you minted and unlock the rest of your collateral.
For example, you deposited 8,400 USDC and minted 10 uSTONKS tokens. At expiry the index price is calculated at 420 USDC per token. The 10 uSTONKS tokens are worth 4,200 USDC. You can settle your 10 uSTONKS for 4,200 USDC. The remaining 4,200 USDC will be unlocked from your collateral.
In case you sold or lost 1 uSTONKS, you would still hold 9 uSTONKS and be able to claim 8,400 USDC — 420 USDC = 7,980 USDC at expiry.
What is 2 Hour TWAP?
2 Hour TWAP Price is the Time Weighted Average Price from the last 2 hours on the highest liquidity Automated Market Maker pool (Uniswap for the time being.)
The 2 Hour TWAP is used to: a) Calculate the number of synths that can be minted b) Calculation basis for liquidations
