📖Spire Overview

Spire is the first based rollup stack called Based Stack on Ethereum, enabling app developers to create their own appchains as based rollups. It enables appchains to interact with Ethereum's liquidity and protocols natively (think: cross-chain swaps).

Based Stack appchains provide decentralized preconfirmations for lightning-fast UX, as well as customization for any use case.

📡 Preconf Router

The Preconf Router is an important piece of the complete Spire appchain vision as it enables the abstraction of preconfirmation complexity from users. Users that opt-in to the Preconf Router can access the benefits of fast preconfirmations without switching wallets, as the Preconf Router implements (and extends) the standard Ethereum JSON-RPC API:
