Jumper Earn
Powering yield discovery and cross-chain actions with vaults.fyi
Overview
Jumper Earn is a personalized yield discovery and execution engine that enables users to move from idle assets to earning positions through a single, intent-based workflow.
This experience is powered in part by the vaults.fyi API, which provides standardized yield data, transaction payloads, position tracking, and attribution across DeFi. Combined with Jumper’s cross-chain routing and LI.FI Composer, users can discover and deposit into vaults across networks without managing complex multi-step flows.
This case study highlights how integrators can use the vaults.fyi API to power yield discovery, execution, and measurable distribution at scale.
The Problem: Scattered DeFi Yields
Despite DeFi’s growth, yield opportunities remain fragmented across chains and protocols. Users face several sources of friction:
Discovery fragmentation: Yield opportunities are spread across dozens of chains and protocols, each with different interfaces and standards.
Asset mismatch: Users often do not hold the exact asset required by a vault, requiring swaps or bridging before depositing.
Execution complexity: Moving from an asset on Chain A to a vault on Chain B can require multiple manual steps (approve → swap → bridge → swap → deposit).
Data staleness: Inaccurate or delayed data can result in failed or suboptimal transactions.
These frictions reduce conversion from yield discovery to actual deposits and create significant integration overhead for applications attempting to unify the experience.
The Solution: A Unified Intent Engine
Jumper Earn reduces this complexity by unifying discovery, execution, and tracking into a single flow.
By integrating the vaults.fyi API, Jumper can access standardized, real-time yield data across 75+ curated opportunities without building and maintaining protocol-specific integrations. This allows Jumper to focus on routing, UX, and cross-chain execution while relying on vaults.fyi for normalized yield intelligence.
The result is an experience that moves users from any asset on any chain to a target vault through a streamlined intent-based workflow.
How Jumper Earn Uses the vaults.fyi API
Jumper Earn integrates vaults.fyi to power yield data, transaction flows, and measurable referral attribution across vault providers.
Market & Vault Data
Jumper Earn uses vaults.fyi as a data layer for:
vault metadata and strategy descriptions
real-time and historical APY and TVL
yield and incentive breakdowns
This standardized data enables consistent comparisons across protocols and reduces the need for custom data pipelines per integration.
vaults.fyi provides market data coverage across all opportunities surfaced in Jumper Earn.
Transactional Support
For many supported vaults, vaults.fyi provides transaction payloads for:
Token Approvals
Deposits
Withdrawals (including multi-step flows where user enters a redemption queue)
These payloads feed into Jumper’s routing engine and transaction orchestration logic.
When execution requires more complex routing—such as cross-chain swaps or multi-step flows—Jumper routes user intents through LI.FI Composer, which bundles actions into a single, user-friendly execution flow.
This hybrid model allows Jumper to support a wide range of protocols while minimizing per-protocol integration work.
Today, vaults.fyi supports a significant portion of Jumper Earn’s transaction flows, with LI.FI Composer complementing cross-chain and multi-step execution.
Position Tracking
vaults.fyi position endpoints help power Jumper’s portfolio visibility by:
detecting existing vault positions
tracking deposited balances
supporting cross-chain portfolio views
This allows Jumper to present a unified yield dashboard without integrating directly with each protocol’s indexing logic.
Adoption Tracking & Attribution
Beyond user-facing functionality, vaults.fyi provides infrastructure for measuring vault distribution and adoption.
Using vaults.fyi data and dashboards, Jumper can:
track inflows originating from Jumper Earn
monitor net TVL associated with their integration
attribute deposits to specific providers (protocols or curators)
This creates a shared attribution layer between:
Integrators, such as Jumper, driving user flows
Providers, such as Gauntlet or Midas, supplying vault strategies
Both sides can reference a neutral, onchain-based source of truth rather than relying on manually reported or fragmented analytics.
For integrators, this supports optimization of recommendations and user flows. For providers, it improves visibility into distribution performance and partnership impact.
The attribution dashboard is currently in beta, with Jumper among the first integrators using it.
Example User Flow
Wallet Connection: Jumper detects assets and existing positions.
Yield Discovery: Relevant vaults are surfaced to the user.
Vault Selection & Execution: The user selects a vault and confirms the action. Swaps, bridges, and deposits are orchestrated via Jumper routing and LI.FI Composer using vaults.fyi payloads where applicable.
Post-Execution Tracking: Positions are tracked using position data from vaults.fyi and other sources.
Results
By integrating the vaults.fyi API, Jumper Earn:
Reduced integration overhead Access to multiple protocols through a single API removed the need for many custom integrations.
Improved conversion Streamlined discovery-to-deposit flows reduced time-to-yield for users.
Enabled measurable distribution Attribution and TVL tracking improved visibility for both Jumper and vault providers.
Standardized yield data Consistent data improved comparability and user decision-making.
Summary
Jumper Earn demonstrates how integrators can deliver end-to-end yield experiences, combining:
vaults.fyi for yield data, transaction support, and attribution
Jumper and LI.FI for routing and cross-chain execution
For builders, this integration model shows how a single API can support discovery, execution, tracking, and attribution—reducing integration complexity while enabling measurable distribution across DeFi.
