Sprinter is **programmable credit infrastructure for the onchain economy**. We replace overcollateralisation with guardrails — for risk-managed credit and maximum capital efficiency.

Apps plug in through a single API and get the full credit stack: flexible terms, adaptive guardrails, and economics powered by DeFi. The end user never touches a protocol — they just get credit that's personalised, adaptive, and affordable. Since October 2025, Sprinter has processed **over \$300M in credit volume with zero shortfalls**.

## Why Sprinter

* **Programmable, not overcollateralised** — credit policies encode what funds can be used for, at what scale, and under what conditions. Less capital posted for the same line; repayment is enforced, not hoped for.
* **Fast and secure** — self-serve API live in hours, custom policies in days. Non-custodial via MPC, with continuous health monitoring and automated risk execution.
* **Productive capital** — collateral keeps earning yield while it backs the credit line; liquidity providers earn blended yield from two stacked sources.

## Who builds on Sprinter

* **Neobanks & Card Programmes** — let users spend against their DeFi holdings without selling, while the program earns yield on held assets. Built on the **Sprinter Credit** API.
* **Crosschain Solvers** — access zero-collateral crosschain liquidity to fill intents, repaid from the user's source-chain deposit. Built on **Sprinter Liquidity**.
* **Asset issuers & AI agents** — instant redemption liquidity, and autonomous, policy-bound credit lines.
