Hot Topics in the Community#
Topic 1: How to quickly send transactions to contracts in Foundry#
- Use the format "address(P).call(calldata)", where "0x" can be omitted.
- Use the format "address(P).call(hex"1234")" to directly send calldata.
- Use Tenderly for faster transaction simulation.
- Use Forge test to check if the contract needs modification.
- Use cast publish TX to send calldata.
Topic 2: Discussion on server resource configuration and prices#
- Choosing appropriate resource configuration can optimize server performance.
- UCloud has poor routes for returning to China.
- AWS has higher prices.
- Vultr provides 10G bandwidth and NVMe hard drives for $120/month.
- Choosing the right cloud server can reduce costs, for example, UCloud's 1C1G server is $56/year.
- Some people choose to rent high-performance servers for data crawling, website building, etc.
Topic 3: Discussion on decentralized exchanges (DEX)#
- Matcha and 1inch are similar and have their own pairs.
- Disabling Matcha's 0x RFQ can avoid OTC order flooding.
- Odos has relatively good exchange rates but high gas fees.
- Dodo has a beautiful interface design.
- 1inch has limit orders but requires Fusion.
- ETH to stablecoin swaps are preferred on-chain.
- The liquidity source of 1inch is unclear.
- OK exchange rates are between Odos and 1inch.
- Setting a minimum slippage or using privacy nodes can avoid sandwich attacks.
