When your business relies on analyzing DeFi credit and capital efficiency, "good enough" data doesn't cut it. You need to see the whole picture across every chain.

For Sprinter, a solver-powered liquidity protocol, this data is the engine behind their business development pipeline. But as a lean team, they faced a classic dilemma: burn engineering cycles building custom indexers or find a unified API that actually works.

Here is how Sprinter uses Zerion API to obtain institutional-grade protocol intelligence without the infrastructure burden.

What is Sprinter? 

Sprinter combines solving-as-a-service infrastructure with credit-based cross-chain liquidity. It has two main products: 

  • Sprinter Stash — a credit protocol that connects LPs who deposit funds and solvers who can take out uncollateralized loans to execute their strategies, 
  • Sprinter Solve — an API that enables the execution of intent-based swaps.

For these products, Sprinter has several different types of partners, including dapps, wallets, and protocols.  

The challenge: The debt blind spot

Sprinter is based on rigorous research.

Before engaging with a partner, the team delves into onchain data, analyzes address behaviour, and simulates scenarios. They look at this data for all chains where they operate: Ethereum mainnet, OP, Base, and Arbitrum. They need to answer complex questions:

  • Who are the power users on this protocol?
  • What are their deposits and outstanding borrowings?
  • How do these positions perform historically?

The team tried several solutions but hit a wall: while most providers could see deposits, they couldn't get clear data on debts. Without liability data, accurately modeling credit risk is impossible.

The alternative was to build custom indexers for every protocol and every chain. That was a non-starter. 

"I have zero interest in building and maintaining indexers. We have more critical jobs to do." — Gregory Markou, Founder at Sprinter

The solution: One API for the full balance sheet

Sprinter turned to Zerion API’s DeFi protocol positions endpoint. Unlike other providers that only surface simple token balances, Zerion provided the complete picture Sprinter needed:

  1. Full liability visibility: Sprinter could see outstanding debt alongside deposits, enabling accurate credit risk modeling.
  2. Mutilchain data: Sprinter could fetch data across all its chains with a single API call. 
  3. Unified schema: Instead of wrestling with raw RPC calls, Sprinter pulls normalized, ready-to-use data directly into their analytics pipeline for further analysis.

The impact: The "BD superpower"

Implementing Zerion API changed how Sprinter sells.

With its Zerion-powered dashboard, Sprinter gets more insight into the protocol’s user base than even the team they are pitching.

"With Zerion, I can do a quick scan, walk into a BD meeting, and tell you all about your protocol. I probably have more info than most teams do on their own protocols." — Gregory Markou, Founder at Sprinter

Key outcomes

  • Zero maintenance: Sprinter avoided the cost and headache of building chain-specific indexers.
  • Faster deal cycles: Instant access to protocol usage allows for rapid qualification of BD opportunities.
  • Better risk models: Complete data on borrowings and transaction history powers more accurate backtesting and pricing simulations.

What’s next

Sprinter continues to scale its credit and capital modeling capabilities. 

By using Zerion as their wallet data layer for onchain memory, they can focus on their core product, trusting Zerion to handle the complexity of multi-chain indexing.
