01 / TOOLBOX
A balance check you can inspect.
Native Balance Check reads one public EVM address at a fixed block. It checks the network and block freshness, then returns JSON and an exit code your existing automation can use.
- One address, one HTTPS RPC, native assets with 18 decimals
- Configurable total deadline; 5 seconds by default
- Standard-library Python; no installation dependencies
- 35 local tests covering success, bad responses and timeouts
The Gumroad starter kit includes the complete source, tests and English/Chinese guides. Suggested contribution: $5; $0 gets the same files.
QUICK START
