The Project

The problem

Wallets and notification services need to know when an address sends or receives funds, without running a full indexer.

What it does

GET /block/current: returns the latest parsed block.
POST /subscribe/{address}: starts monitoring an address.
GET /transactions/{address}: returns inbound and outbound transactions for it.
Swagger UI documents the whole API.

How it’s built

/internal/rpcclient: JSON-RPC communication with an Ethereum node.
/internal/parser: core parsing and in-memory storage.
/api: HTTP layer, with make targets to build, test, run and generate the docs.
