1.2 Key Technological Facts

Avalanche is a high-speed smart contracts platform that supports sub-second finality and Visa-level throughput.
Avalanche features complete support for the Ethereum Virtual Machine, and thus, Ethereum tooling works out of the box. Truffle Suite, Remix, MetaMask, MEW, and all your other favorite Ethereum tools.
Avalanche supports application-specific-sharding, empowering developers to launch applications that conform to their own specific needs.
