Catching Hidden Transfers, Real-Time Events, and Multicalls

Most devs know how to deploy contracts and send transactions, but a lot of the real tricks happen when you start listening to the chain. For example, not every ETH transfer shows up in an ERC-20 Transfer log sometimes the only way to catch them is by inspecting internals.

Or for example take Multicall: instead of blasting your RPC provider with dozens of requests, you can batch them into a single call at the same block height, which is both cheaper and more accurate.

In the latest post there is deeper dive into these ideas:

1. How to filter ERC-20 Transfer logs with eth_getLogs
2. Subscribing to events in real time instead of polling
3. Why some ETH transfers leave zero traces in events (and how to detect them through internals)
4. Using Multicall to batch calls and stay in sync with the chain

If you’re building dashboards, monitoring tools, or debugging dApps, these tricks can save you a ton of time and RPC quota.
