API 2.0 is currently in public beta and runs in parallel with v1; we're polishing edge cases and releasing tweaks to ensure the migration can be accomplished smoothly.
The documentation for API v1 can be found here.

Welcome to Yield.xyz

Yield.xyz is the most complete API for integrating non-custodial, on-chain yield — including staking, restaking, liquid staking, DeFi lending, RWA yields, vaults, and more. Whether you're building a wallet, custody platform, neobank, exchange, or on-chain agent, Yield.xyz gives you one standardized interface to access yield across 70+ networks.

Designed for full self-custody, the API constructs complete transaction flows but leaves execution and signing entirely in your control — compatible with browser wallets, smart contract accounts, MPC, and institutional custody platforms.

Originally developed as the backbone of Omni, one of the most advanced staking wallets in Web3, our infrastructure has been refined through years of production use and real-world feedback. Today, it powers Yield.xyz — the trusted yield layer behind platforms like Ledger, Zerion, and Tangem, serving 4M+ users and supporting hundreds of millions in monthly volume.

Why Yield.xyz?

• Unified Interface — Every protocol and opportunity is abstracted into a consistent, schema-based format: one format for metadata, one for actions, one for balances.
• Instant Integration — No need to write custom logic for Cosmos staking vs. Aave lending — integrate once, support everything.
• Self-Custodial by Design — Transactions are returned fully constructed but never executed — you sign and broadcast using any infrastructure: wallets, smart contracts, or custody platforms.
• Battle-Tested Infrastructure — Built on the stack that powers millions of real-world transactions and billions in TVL.
• Composable — Chain together multiple yields to build cross-chain workflows (e.g. bridge + stake + restake) in a single declarative call.
• Chain-Agnostic — Works across EVM and non-EVM chains, including Ethereum, Cosmos, Tron, and soon Solana.
• Monetizable — Configure deposit, performance, and management fees or earn validator rebates directly in your integration.

What You Can Build

• Wallets — Add staking, DeFi flows with full control over UX, signing, and monetization.
• Custodians & Fintechs — Offer on-chain yield on crypto or stablecoin balances with full transparency and fee control.
• AI Agents — Query all available yield actions and execute optimal strategies using standard schemas.
• Aggregators & Infra — Compose multi-step flows using a unified transaction model — no chain-specific code required.

What You Get

• Yields — Each yield represents an opportunity: staking, restaking, lending, vaults, or RWA strategies — with standardized metadata, reward mechanics, and execution logic.
• Actions — Each yield supports consistent actions like enter, exit, and manage, using schema-based inputs.
• Balances — Retrieve unified views of user positions across all lifecycle stages: active, pending, cooldown, claimable, and more.
• Protocols — Yields can be grouped under known brands or ecosystems (e.g. Aave, Cosmos, EigenLayer) for easy discovery and filtering.

Developer Experience

API

Use our REST API to discover yields, construct transactions, and manage user positions. Everything is normalized across chains, lifecycle-aware, and compatible with your existing infra. Explore the API reference to get started.

SDKs

For TypeScript projects, our SDKs offer a type-safe interface over the API — with built-in helpers for signing, formatting, and transaction management. Supports hardware wallets, mnemonics, and contract wallets out of the box.

Guides & Recipes

Get started in minutes with our Core Concepts and ready-made code recipes — covering common flows like staking, restaking, claiming, or multi-step actions.
