seoTitle: Solana DeFi Development, Markets, Swaps, and Trading
description:
  Build trading systems, integrate DEXs and oracles, and run financial
  applications on the chain where DeFi settles in milliseconds for fractions of
  a cent.
---

Solana's single global state, ~400ms block times, and sub-cent fees make it the
home of onchain finance and DeFi: every program - DEXs, lending markets,
oracles, perps - is composable within a single atomic transaction. This section
is the workflow layer for building financial applications; it links down to
[Core Concepts](/docs/core/transactions) and the
[cookbook](/developers/cookbook) for the underlying mechanics.
