# The Easiest Way to Integrate with DeFi Yield

The Gauntlet Developer Kit gives you everything you need to add yield to your app — curated vaults, battle-tested infrastructure, and a complete integration layer so you don't have to build it yourself.

* **Gauntlet Vaults** — Institutional-grade yield strategies curated by Gauntlet across DeFi protocols and chains
* **Vault Infrastructure** — Responsive, flexible, and secure onchain protocols and offchain systems that power those strategies
* **Gauntlet SDK** — Single client for vault discovery, deposits, withdrawals, positions, and attribution. Wraps the API for data and communicates onchain via your RPC URLs for transactions.
* **Gauntlet API** — The raw REST API underneath the SDK. Use it directly if you need full control or are working outside TypeScript.
* **Gauntlet Developer Portal** — Register your app, provision API keys, track attribution, and manage payments

## Why Gauntlet Developer Kit?

* **Easiest Access to DeFi Yield** — A single API to access, compare, and interact with yield opportunities across all Aera and Gauntlet vaults.
* **Seamless Integration** — Integrate once and support all vaults and strategies.
* **Chain-Agnostic** — Works across EVM and non-EVM ecosystems, including Ethereum, Base, Optimism, Arbitrum, and Solana.
* **Monetizable** — Earn fees on deposits routed through your integration. Fee recipients are configured onchain via the FeeVault contract, with built-in attribution tracking for volume reporting and revenue reconciliation.
* **Proven in Production** — Powers Aera and Gauntlet-managed vaults, backed by a team with 8+ years of DeFi experience and a long track record managing substantial TVL across DeFi protocols.
