Products
Euler's core building block is the vault. EVK vaults can stand alone or connect into lending markets, while EulerEarn vaults allocate deposits across approved strategies. The Euler app, the SDK, and the Data API provide different ways to use or build on these products; the app is open source and can be self-hosted.
This page is about Euler's product lines. A curator's product in the Toolbox is something else: a named group of that curator's vaults on one chain; see Markets and products.
Vaults can form isolated collateral-debt pairs, pooled borrow markets with selected collateral, or cross-collateralized clusters. Each market configures its own collateral relationships, oracles, interest-rate models, hooks, caps, governance, and liquidation parameters.
Product lines
EVK vaults are the primitive the rest of the stack is built from: isolated markets connect them for lending and borrowing, and EulerEarn allocates deposits across them.
ERC-4626 lending vaults with borrow support, hooks, caps, governance, and configurable collateral relationships. Every Euler market and Earn product is built from these vaults.
EVK vaults connected into collateral and borrow markets with scoped risk. Use them for asset-specific lending, tokenized asset markets, and markets with custom collateral, oracle, cap, and LTV configuration.
ERC-4626 aggregation vaults where deposits are allocated among strategies permitted by the vault's configuration.

- Price Oracles: valuation routes and units of account.
- Interest Rate Models: how vault borrow rates respond to utilization or time.
- Hooks: operation-specific policy checks and custom logic.
- Curate: deployment, configuration, governance, and operations.
