DappRadar - an application that allows you to track various aspects, such as viewing statistics and details of different dapps, checking ratings and statistics of DeFi projects, reviewing statistics of various NFT collections on different blockchains, tracking your or someone else's NFT portfolio or cryptocurrencies in three networks (Ethereum, BNB Chain, Polygon), monitoring cryptocurrency statistics, and much more. Most of the functionality that can be useful to you is entirely free.
Gas Price Estimation Websites
**Gwei, Blocknative** - two of my favorite websites for gas estimation. These sites will tell you how much it will cost to approve an NFT, swap ETH for WETH, create a collection, and more.
Transaction Tracking
Zapper - one of the best trackers for your wallets. You can add all your wallets in one place and monitor changes in these wallets. You can also group them, for example, create two groups, one with wallets of different influencers and the other with all your wallets. You can track them collectively and see the total balance and more. Another advantage is that it has a mobile app.
Distribute ETH or Tokens Between Wallets
MultiSend - a website that helps you quickly distribute ETH or tokens to various wallets.
Generate a Tax Statement
NFTBank - a website where you can obtain a statement of your transactions for tax reporting.
Check Token Unlock Schedules
Token Unlocks - a site where you can check when a project's tokens will be unlocked and what percentage of the total supply that represents. You can use this information to your advantage.
