If you use the LP whitelisting to disable public LPs, and wish to add liquidity yourself later, you will need to add your DSProxy address (if you're using the GUI) to the whitelist in order to do so. You would think this wouldn't be much of a problem, since they would be buying at the initial price (which should be set higher than market). If you contribute significant long-term liquidity to the platform, you can apply to have smart contract deployment gas costs reimbursed from the Balancer Ecosystem fund. Liquidity Bootstrapping Pool. The liquidity bootstrapping event is here! These times default to 2 hours and 2 weeks, meaning the weights cannot change faster than every 2 hours, and once you start a gradual update, you cannot add a token or do a manual update for 2 weeks. The Balancer Liquidity Bootstrapping Pool event is an excellent way to buy GDT at preferred prices. It is possible for "whales" to unbalance your pool by adding large amounts of "single-sided" liquidity, instantaneously changing the prices, possibly enough to induce arbitrage and impermanent loss. That way anybody front-running your pause transaction will pay a 10% fee on top of the high price. Liquidity Bootstrapping Pools (LBPs) are smart Balancer pools that allow projects to optimally bootstrap liquidity for their tokens. ), In an LBP, buyers suffering sticker shock need only wait for the weights to adjust and the price to start dropping. Since the core of the strategy is changing weights, you absolutely need to enable that right. If you need to call removeToken to reuse the pool, remember you can always "buy out" the other LPs. For instance, to go from 96%/4% to 30%/70%, the start weights would be 24/1, and the end weights would be 7.5/17.5 - notice that both total to 25. Via the Balancer subgraph Use price oracles. Watch out for some subtleties here! For example, if you believe the fair price for your token is $2, you may want to consider an opening price that is up to $10. Perhaps you have a staking protocol, and encourage LPs to stake their BPTs for additional earnings. The change in price gradually incentivizes investors to buy your token in exchange for the reserve asset(s), which then changes the balances of assets in the pool. Buyers can set this to a higher value (e.g., 1-2%), to increase the chances of success. Also keep in mind that contracts cannot change state by themselves - weights only change when someone calls. The Radicle network will offer 3.75m Radicle tokens over 48 hours, from 25.2.2021 ~16:30 UTC till 27.2.2021 ~16:30pm UTC. Bitcoin; Alt Coin; Ethereum; Technology; Exchanges; Globe announces the upcoming Balancer Liquidity Bootstrapping Pool for GDT. Changing the target pool weights influences price, such that increasing the weight of an asset increases its relative price, and vice versa. For instance, if your weights are very close to the min/max weight boundaries, could fail in some edge cases where the total would temporarily be exceeded. You can't beat human nature. Though most LBPs are two-token pools (e.g., a project token and a single reserve currency, usually a stable coin), it is possible to have three tokens, or more. If you take this approach, there are a few things to keep in mind. This is possible because projects can provide only a small fraction of the total pool value in ETH and/or DAI (e.g. How do I change the weights of my LBP while it’s live? We've tried to make it as clear and straightforward as possible - but there are subtleties the GUI handles that you would need to hand-code in a script. At the end of the sale, Remove Liquidity to recover the proceeds; i.e., the reserve balance, plus any unsold tokens. Though most LBPs are two-token pools (e.g., a project token and a single reserve currency, usually a stable coin), it is possible to have three tokens, or more. We have observed an initial price spike on just about every LBP (possibly just lots of retail volume on the initial announcement) - and avoiding this is one reason to delay the start of the LBP. The design of the LBP tends to keep the sale price fairly even (or slightly declining) during the sale. Some LBP owners might want to allow public LPs; Uniswap does, after all. However, it is possible to create the pool first, and start the actual sale (= gradual weight change) a few hours or days later, with trading paused in between. There is a simulator available for this case. Balancer is a protocol for programmable liquidity that allows anyone to create liquidity pools. If you are launching an LBP and want to make sure that your token is listed on the exchange before launch, please. To transfer it back, just call setController again from that script, setting it to your DSProxy address. If you want to do an LBP this way, while ensuring there won't be a price spike, you have several options: 1) The only absolute sure way, for teams with the technical expertise to do so, is to deploy and pause in the same transaction The contract always interpolates linearly between the start and end weights - but the resulting price curve will only be linear if the weight totals match. Globe will auction 4.00% (16,000,000) of the total $GDT token supply in a Liquidity Bootstrap Pool (LBP) by Balancer. So the upshot of all this is if you intend to allow public LPs on your LBP, maybe you don't need the add/remove token right. If this is a one-off auction, you can enable the right, and redeem through two "removeToken" calls. The Whitelisting round was oversubscribed by more than 500X. (This would surely be the case for "perpetual synthetic" pools that add and remove synthetics as they are minted and expire.). All the other LPs wishing to withdraw their liquidity would get their proceeds entirely in DAI. pools during the sale, it would be a good idea to mention in your announcement that there is only one official pool - which does not allow adding liquidity - and any users who add liquidity to any "imposter" pools, or send them to any account they do not control, will lose funds if they fail to withdraw them before the end of the sale. A smart pool is a contract that controls a Balancer core pool, which contains the tokens and is used on the exchange. In this case, it's important to make your users aware there might be "counterfeit" pools, and clearly direct them to your pool, whose tokens your staking contract accepts. No, you do not need any additional capital beyond the initial seed amount based on the starting weights you’ve selected for your pool. After providing the initial seed capital needed to launch an LBP, do I need to deposit additional capital later? One project was recently launched that way. If you need to call, to reuse the pool, remember you can always "buy out" the other LPs. If it changes too much, the transaction will be rejected - but you will still be charged some gas. Tokens do not need to request to be listed on the exchange, as it is done proactively. allow adding liquidity - and any users who add liquidity to any "imposter" pools, or send them to any account they do not control, will lose funds if they fail to withdraw them before the end of the sale. In the upcoming LBP sale, a … This does not mean you’re trying to sell the token above what it’s worth. In practice, we have seen that the market is efficient. To transfer it back, just call. What are the recommended starting and ending weight configurations for an LBP? Trước khi tìm hiểu Liquidity Bootstrapping Pool mình sẽ nhắc lại các loại pool của Balancer.. Dành cho những bạn chưa biết thì Pool của Balancer có 3 loại gồm 1) Shared Pool 2) Private Pool và 3) Smart Pool. Here's the general process to deploy a Liquidity Bootstrapping Smart Pool, conduct the token sale, and recover the proceeds: When you've decided on parameters as described above, create the smart pool. There is a case where you might want to retain both pausing and swap fee rights: the delayed launch LBP. And they must have the tokens available to do it. (Best practice is to copy/download it, then customize to your own use case. Watch out for some subtleties here! Since smart pools are created with swapping enabled, pausing is a separate transaction, so it is possible to "front-run" the pause transaction and perform a swap before the pause takes effect. If you contribute significant long-term liquidity to the platform, you can apply to have smart contract deployment gas costs reimbursed from the Balancer Ecosystem fund here. If the pool controller has the add/remove token right, they might not even be the same tokens. See Balancer’s Liquidity Bootstrapping Pool … Pinterest. Unless you need the maximum 98%/2% (49/1 denorm) weights, it's best to use weights that sum to a lower total number (e.g., 38/2), and put the project token first in the list when you create the pool, so that the weight, would be processed first. You can submit your pool metadata on this form (e.g., token symbol and name, icons for the token and pool, descriptive text, a url for the sale page, etc.). Consequently, if the controller tries to destroy the pool after the sale with calls to removeToken -- it won't work, because they won't have enough pool tokens. See the, page for staking and other special cases. This may seem counterintuitive, but since LBPs work differently than other token sales, your starting price should be set much higher than what you believe is the fair price. Google+. The Balancer Liquidity Bootstrapping pool will follow the Initial DEX Offering on Polkastarter. The models below are only an illustration of the basic operation of the LBP function. Also, the protocol prevents adding more than half the current balance of any token in a single transaction. Large initial balances (and swap fees) mitigate this risk. The liquidity bootstrapping pool will kick off on the 14th of February 2021, via Balancer. The bottom line is, there will very likely be an initial price spike, so "delayed" LBPs are vulnerable to this kind of front-running. Balancer is an automated portfolio manager and trading platform on Ethereum. You then have time to educate your consumers to buy slowly and not get rekt. If you want to re-use the pool (e.g., there are "phases" or multiple releases), you can leave this right disabled, and retrieve the proceeds through repeated calls to exitPool. (If they are impatient, they can call the public pokeWeights function themselves to tell the contract to update weights to the proper values at the current block.). Via a Liquidity Bootstrapping Pool (LBP) Get Balancer data. We would recommend at least 3 days, but you are certainly free to make it shorter if you believe it would better serve your particular case. You could also prevent others from adding liquidity through the cap right. For instance, a balance of "10" in wei would be "10000000000000000000" for DAI (with 18 decimals), but "10000000" for USDC (with 6 decimals). As an ERC20 utility token, GDT provides discounts on trading fees and also naturally decentralizes long-term ownership of the token away from Globe and to its community via buy & burn so that every trade uses some GDT as fuel. However, this depends on the market buying pressure, which can only be estimated until the sale actually begins. It is essentially a "Uniswap" pool before the sale starts. ), to request eligibility for governance token rewards. The price is derived from two values - balances and weights. Your weight "flipping" schedule determines how the weights will change over time, but (unless you intervene with further issuance or buybacks), balances only change through trades: mostly people buying your token with the reserve currency. Can I deploy/control the LBP from a script? You can refer to the large test suite for many examples of how to interact with the CRP, and both the CRP suite and the Vue app contain helper functions for things like slippage and adding/removing liquidity. You want to enable as few rights as possible. For instance, to go from 96%/4% to 30%/70%, the start weights would be 24/1, and the end weights would be 7.5/17.5 - notice that both total to 25. Further experimentation with AMMs has led to the creation of liquidity bootstrapping pools (LBPs). This makes sense - otherwise, pool owners could "drain the pool" just by calling, Depending on the balances, removing one of the tokens "might" work. In an LBP, buyers suffering sticker shock need only wait for the weights to adjust and the price to start dropping. In this era of high gas prices (not to mention high ETH prices), many traders try to lower the fees by entering lower values. If you're 250 pool tokens short of what you need to remove the project token, you can join with 250 pool tokens' worth of DAI, after which removeToken will succeed. You can choose up to 7 other tokens to be used as reserve assets in your LBP token sale. Even though it's irrational, and the LBP announcements all encourage people to wait, we have observed an initial price spike in nearly every LBP to date. Decide on critical parameters, such as sale duration, starting and ending weights, and estimate the demand (i.e., expected sale rate), using the LBP simulator to adjust the settings until you are happy with the resulting price curve.
