# Sauce documentation

Build programmable EVM and Solana transactions with `@eco-incorp/sauce`, and compose EVM
executions into Eco intents. Solana execution uses the direct Kitchen client; the
[legacy SVM intent helper](guides/solana.md#svm-destinations-in-eco-intents) is incompatible
with the released engine.

**New here?** Follow the [quick start](guides/quick-start.md), explore
[token and protocol globals](guides/protocols-and-tokens.md), then
[create and fund an intent](guides/intents.md). Complete programs live in the
[examples](examples/README.md).
