Community Hot Topics#

Experiences with friend.tech's race and number grabbing#

1. The project developer monitors new users and fans' numbers on the base using smart contracts, and starts buying operations when the conditions are met, but there are also cases of condition errors, so caution is needed.
2. Someone mentioned the method of grabbing money on the base, including obtaining the addresses of influencers and waiting for them to deposit, and then continuously making purchases. This strategy is considered effective.
3. The discussion involves comparisons of different encryption projects, including FTRoom, BSC imitation disk, etc., as well as their own experiences and profits.
4. The discussion also mentioned the method of using AI to batch grab numbers, and some users shared their profit situations, including 0.1u and 0.5u. In addition, some people are concerned about whether the shareholding only increases and does not decrease.
5. Someone mentioned that a user's key may have rug risk and needs to be vigilant. At the same time, some users mentioned that the bot they use only makes purchases.

Discussion on alternative proxy tools#

1. In the discussion, someone asked if they are using soft routers and mentioned that they are using OpenClash. Another person answered affirmatively and said they are using OpenClash, but encountered problems.
2. Another person said that they have fully adopted Surge and believe it is more worry-free. Someone asked if Surge can be installed on a soft router and suggested buying a Mac Mini M2 as a soft router and using the Surge client on Mac. However, someone also mentioned that their Mac is facing performance issues and a series of configuration problems.
3. Someone plans to buy a Mac Mini M2 on Pinduoduo to use as a router.

Requesting and storing transaction data in the tens of millions#

1. In the discussion, someone mentioned dealing with transaction data in the tens of millions and asked whether to use MySQL or big data databases (such as ClickHouse) for storage. Someone suggested using ClickHouse.
2. The discussion involves storing balance data of USDT and WETH liquidity pools and stating that there are 9 million data on-chain. They want to store the data locally to improve query efficiency without relying on APIs.
3. Someone mentioned that using API to query prices is not enough and needs to find the price of a specific block number. Other members suggested using RPC service providers to obtain balance data of block numbers and addresses, with Ankr mentioned as a free choice.
4. The discussion involves analyzing the historical transaction data of tokens, calculating the buying and selling prices at that time, and how to obtain the price of a specific block number. It is recommended to use Ankr's archival node to obtain the required data.
