# Binance Incubation Projects By [Web3 World ](https://paragraph.com/@web3-world-2) · 2023-01-21 --- Bracket labs ( Twitter ) is one of 12 projects ( article link ) selected for Binance Labs’ fifth-season incubation plan. bracketx is its first product (decentralized options), currently it has three functions: bracket, channel, and epoch. Bracket has launched the Arbitrum one main network , and channel and epoch have just launched the Arbitrum Goerli test network . Make sure that the wallet has eth in the Arbitrum Goerli test network, if not, you can join ( official DC ) to lead the water. Click on the channel and enter /claim + address + Both to receive eth and usdc. Next, enter the test network: first introduce the first function BRACKET. In the upper right corner of the page, you can choose BTC, ETH and then buy call or put options. There are also bnb, sol, etc. on the main network. There are 5x and 10x leverage on the testnet, and only 10x on the mainnet. Click on the 4-hour 5-times BTC call option: This call option means that the BTC price will rise to the range of 20940-21982 within four hours after the purchase, and the maximum gain of 5 times can be obtained. Here 20940=20836 (1+ 0.5%), corresponding to the underlined part in the figure, 0.5% non-fixed value, please refer to the official document for details on the pricing model (related links can be found in official-links of dc). The minimum purchase is 10U, denominated in ETH. The max buy in the figure shows the maximum purchase amount, and the liquid depth is the funds deposited in the fund. This part will be discussed later. After purchasing, click on my trades-owned-bracket to see the order you just placed. The active and time buttons are used to sort your past orders. As you can see in the picture below, there is a green claim button. This button will only appear when the bracket you purchased makes money. You can choose to exercise the right immediately, or wait for it to be automatically executed when it expires. The second function channel introduction: select buy-channel on the web page, and select btc and ETH in the upper right corner. The difference here is that it is not bullish or bearish, but whether the price will be within a certain range in the future. Take the btc channel that triples in 24 hours as an example: Suppose I buy 10u at btc 21112, if btc stays between 20437-21788 (21112±3.1%), the value of this channel will gradually increase from 0 over time , the value accumulates over time. If the price is still in the range or breaks through this range after 24 hours, the order will be automatically settled (the settlement ratio of the breakout range should be based on the actual situation). Click on my trades-owned-channel to find the order just now. Before entering the epoch, I would like to introduce the function of fund first: risk: fund can be regarded as the seller of the option, as the seller can receive the buyer (buy) premium (premium), the previous example of bracket is 10u, if it is 5 times the option in 4 hours, then you may lose 50-10=40u (this is rare, btc will rise or fall by more than 5% within 4 hours). Click on fund-bracket, you can choose btc or ETH, there is a step before the first deposit is approve, and then deposit usdc before reset (dc can receive 10000 at a time), if you want to withdraw, change the number to 0. Then choose the liquidity pool you want to deposit into. You can click depth to view the percentage with the best depth and then fill in or click the = sign to match the current depth. After setting, click the update button at the bottom of the page. --- *Originally published on [Web3 World ](https://paragraph.com/@web3-world-2/binance-incubation-projects)*
