vaults.fyi

Vaults.fyi is a DeFi infrastructure platform designed to simplify onchain earning by providing a unified API for yield discovery, execution, tracking, and monetization. It abstracts the complexity of interacting with multiple DeFi protocols and chains, allowing developers to integrate yield opportunities into their products with minimal effort.

The platform powers earning functionality for major ecosystem players including Kraken, Jumper (LI.FI), Arbitrum, and Gauntlet. It aggregates data and actions across 80+ DeFi protocols and 20+ blockchain networks such as Ethereum, Solana, Base, Arbitrum, and BNB Chain.

Vaults.fyi provides four core capabilities through a single integration:

1. APY data and historical metrics across protocols and vaults

2. Ready-to-sign transaction payloads for deposits, withdrawals, claims, and redemptions, executed non-custodially against the underlying protocol contract directly with no proxy or intermediary in the path

3. Position tracking and onchain attribution

4. Built-in monetization, where integrators earn revenue share on the protocol rebates their flow generates

Vaults.fyi acts as a middleware layer that enables wallets, exchanges, and applications to access yield strategies without building custom integrations for each protocol. It provides APY data, historical metrics, and ready-to-sign transaction payloads for core DeFi actions like deposits, withdrawals, claims, and redemptions—all executed non-custodially directly against protocol smart contracts.

Additionally, Vaults.fyi introduces built-in monetization, allowing integrators to earn revenue through protocol rebates generated from user activity. This makes it not only an infrastructure solution but also a revenue-enabling layer for DeFi-enabled products.
