Overview

Sprinter Credit is a programmable credit layer for individuals and agents. We don’t just issue credit — we make credit configurable. The first version of Sprinter Credit (V1) provided zero-collateral credit for crosschain solvers and processed over $200m USD in volume within the first months. With V2 we take credit beyond solvers and bring the benefits of programmable credit to neo finance and the agentic age. On a high-level, Sprinter Credit (V2) consists of the following components:
  1. Credit Engine The core credit issuance and management system. Handles credit line creation, drawdowns, repayments, and liquidations across supported networks.
  2. Supported Assets & Strategies Collateral assets, earn vaults, LTV parameters, and chain support — all in one reference.
  3. Policy Engine Credit policies enable Sprinter Credit to 1) provide favorable credit conditions and 2) enable users and applications to constrain usage of credit.
  4. Liquidity Layer The Sprinter Credit Liquidity Layer provides the liquidity required for the credit engine. The Sprinter Credit Liquidity Hub & App allow Liquidity Providers to earn yield by providing capital.
Sprinter Credit enables applications to get purpose-fit credit lines for their users:
  • Card Programmes fund card spend just-in-time, so users don’t have to hold assets idle
  • Neobanks provide a DeFi-powered liquid savings account, so users can spend their assets while having them earn yield in DeFi
  • Agents access a human-delegated undercollateralized credit line to trade extended leverage on Hyperliquid

Supported Chains

The Sprinter API uses CAIP-2 identifiers for chain references. CAIP-2 (Chain Agnostic Improvement Proposal 2) is a standard format for identifying blockchains: namespace:chainId — for EVM chains this is eip155:<chainId>. You’ll see CAIP-2 identifiers in API responses (e.g. the chain field in contract calls) and as path/query parameters in several endpoints.
