A blockchain is a public network maintained by many independent validators rather than a single company. Shiga is built on EVM-compatible networks — Ethereum and fast, low-cost Layer 2s such as Optimism and Base — where transactions settle in seconds for a tiny fraction of traditional costs. By contrast, rails like SWIFT can charge up to ~$20 and take days. Because these networks are decentralized, you keep self-custody and full control of your wallet.
