# DeFiKit

> Unified access to DeFi lending, vaults, stablecoins, and yield strategies across 80+ networks

DeFiKit is the Yield.xyz kit for integrating **DeFi and stablecoin yield** through a single, non-custodial interface — spanning lending markets, vault strategies, liquid staking, and RWAs across 80+ networks and 2,900+ opportunities.

## Core capabilities

* **Unified API for enter / exit / manage** — Ready-to-sign, ordered unsigned transactions across DeFi strategies. Your stack signs and broadcasts.

* **Rich metadata for discovery and approvals** — TVL, capacity signals, APY windows, and risk signals for informed decision-making.

* **40+ DeFi protocols (and growing)** — Consistent primitives and lifecycle-aware position tracking across Aave, Compound, Morpho, Yearn, Ethena, and more.

* **Multi-chain coverage** — Same protocols, same API across Ethereum, Base, Arbitrum, BNB Chain, Polygon, and 80+ networks.

* **OAV support (optional)** — Optimized Allocator Vaults for auto-compounding, reinvestment, and cross-chain routing with configurable deposit/management/performance fees.

* **Security posture** — SOC 2 Type I completed; Type II in progress (expected Q1 2026). See [Security & Compliance](/documentation/shield-security/security-compliance).

## Integration at a glance

<Steps>
  <Step title="Discover DeFi opportunities">
    List supported yields with metadata (APY, TVL, capacity) using the [Discovery API](/api-reference/YieldsController_getYields).
  </Step>

  <Step title="Request an action">
    Call `enter`, `exit`, or `manage` for a chosen yield. See [Actions](/documentation/core-concepts/actions) for the full model.
  </Step>

  <Step title="Sign & submit">
    Execute ordered transactions using your wallet/custody infrastructure. See [Transaction Submission](/documentation/build-with-api/transaction-submission).
  </Step>

  <Step title="Track positions">
    Use balances to track lifecycle states, rewards, and follow-up actions. See [Balances & Positions](/documentation/core-concepts/balances-positions).
  </Step>
</Steps>

## OAV & monetization

**Optimized Allocator Vaults (OAVs)** are optional smart contract wrappers that enable:

* **Auto-compounding / reinvestment** — Automatic reward harvesting and redeployment
* **Cross-chain routing** — Optimal yield allocation across networks
* **Fee monetization** — Configurable deposit, management, and performance fees

OAVs are deployed per-partner and can be customized to your business model.

## Security & compliance

DeFiKit inherits Yield.xyz's security posture:

* **SOC 2 Type I** — Completed
* **SOC 2 Type II** — In progress (expected Q1 2026)
* **Non-custodial architecture** — Yield.xyz never holds user funds or keys
* **Shield integration** — Transaction decoding, validation, and intent verification for institutional flows
