​[See Liquidity Provisioning section] ​
How do I report a bug in your system?
​[See bug bounty rules]​
Has Clipper been audited?
Clipper went through source code audits with Solidified and Quantstamp. [See Audits] 
Wallet Questions
How do I connect my wallet?
Connect to your wallet by clicking "Connect Wallet", then select your network, and choose your wallet. A prompt from your wallet will pop up to log in. 
I have a hardware wallet. Can that be used as well?
Yes, any hardware wallet that is compatible with your crypto assets’ token standards can be used with Clipper.
Liquidity Provisioning (LP) Questions
How is Clipper's liquidity program different than other DEXs?
See [Liquidity Provision].
Will there be a limit on how much I can deposit?
Yes. You will be limited in your deposit to keep the pool at an ideal volume for retail traders. When you connect your wallet, you will be able to see you deposit limit. 
How long will my deposit be locked before I can withdraw?
Your deposit will be locked for a short period of time that varies with each chain. You will be shown your deposit lock period once you've connected your wallet. After the period has ended, you can unlock it, then withdraw. 
Who can add a deposit?
Anyone who has whitelisted their wallet address has the chance to participate in Clipper's liquidity program. You can whitelist your wallet during registration periods. View registration events here. If you miss a registration period, don't worry, there will be more.
How does a token's current balance in the pool affect the value of a deposit?
Liquidity providers will be granted a larger number of pool tokens (and therefore, a higher percentage of pool ownership) for depositing assets that are currently undersupplied in the pool.
By looking at the star rating next to each asset, you can see how it's supply in the pool will impact your deposit. (i.e. An asset rated with 3 stars is undersupplied, therefore a deposit of this asset may be more likely to increase in value. An asset rated 1 star or 0 stars is oversupplied in the pool, therefore a deposit of this asset may be less likely to increase in value.)
What policies ensure that the Clipper pool will remain at the optimal size for small trades?
The pool is restricted to whitelisted addresses and a deposit limit. This regulates the total amount of deposited capital in the Clipper pool.
How do I get on the whitelist? You should include XYZ on the whitelist!
We want active members of the community to participate, so we are taking a whitelist approach. Currently, whitelisting involves being an active and verified member in one or more Discord servers, including the Clipper discord server.
Questions about Transaction Issues
I'm having problems transacting on Polygon. Is it a problem with the Clipper website or with my wallet?
To check, disconnect your wallet and refresh the page (be sure that the red button says "Connect your wallet"). If you are able to get a quote for the assets you want to swap, then the problem is with your wallet, specifically, with the RPC endpoint that you used to set up the Polygon network.
We suggest the following RPC endpoints for Polygon:
1.We believe that Polygon-RPC is the best anonymous public choice. Set your RPC URL to https://polygon-rpc.com to use it.
2.​Infura is robust, stable, and highly performant. It is what the Clipper developers and website use. It is free for individual accounts but signing up requires a credit card.
3.​https://rpc-mainnet.matic.network/ OR https://rpc-mainnet.maticvigil.com/ are less favored but can be used if necessary. We have frequently observed problems with these endpoints.
We've also found Polygon to be more unreliable than the ETH mainnet, and so you may be observing issues with the Polygon network itself as opposed to the specific RPC endpoint you've selected.
If you cannot get a quote from the webpage after disconnecting your wallet, then the problem is with the Clipper website and we'd appreciate you letting us know in Discord.
Why did my transaction fail ?
The most likely explanation is that your order took too long to reach Clipper's on-chain market maker. In Clipper's FMM architecture, the market maker's quotes are only valid for a certain window of time (which changes based on chain). Please try again.
Why is my transaction pending for so long?
The most likely explanation is that the gas price associated with your transaction was too low for miners to consider including it in a new block. Depending on your wallet, you may be able to cancel your pending transaction, or to re-submit it with a higher gas price. Etherscan maintains a detailed "Gas Tracker" page with frequently updated estimates of execution price and timeliness.
Will my gas cost be refunded?
As is typical for interactions on blockchains, any gas that was not consumed by a transaction on Clipper will be refunded to its sender.
Questions about Governance and Tokens
When will you have governance?
​[See Governance]​
Why can't I find the token I am looking for?
Clipper was designed to offer the best trading prices for ordinary crypto traders, for the most popular and commonly traded cryptocurrencies. In order to do so, Clipper’s liquidity pools need to be carefully optimized, and it would not be beneficial to our users if we included a wide catalog of less frequently traded tokens, at the cost of maintaining our core assets and user base.
What bridge does Clipper use for Moonbeam assets?
For USDC, USDT, WETH, WBTC, and DAI, Clipper uses the Nomad Bridge. We believe this bridge is the safest, most secure, most trusted bridge to transmit assets onto Moonbeam. It was specifically recommended to us by the PureStake team that operates Moonbeam.
For MOVR, Clipper uses the Meter Passport bridge from Moonriver onto Moonbeam. We selected this bridge because MOVR is the native token on Moonriver.
How do I get air drops?
No airdrops have been announced by Clipper.
If you see any posts about upcoming airdrops, giveaways, or any other unexpected promotion, be sure to verify the authenticity of the message and sender and always be on the lookout for impersonators and other scammers.
Will Clipper have its own Token?
Clipper does not yet have its own token.
