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.

​
What you can build

Wallets & Super Apps

Embed DeFi yields directly into wallet UX — let users earn on idle assets with one tap.

Neobanks & Fintechs

Offer competitive savings rates backed by DeFi protocols, with full compliance controls.

Custodians & Asset Managers

Enable institutional clients to access DeFi yield with custody-grade signing workflows.

Treasury & Corporate

Optimize idle treasury assets across lending markets and stable yield strategies.

​
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.

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.
