Sprinter Sprinter is programmable credit infrastructure for the onchain economy. We finance the gap between when value is promised and when it settles — and we replace overcollateralisation with guardrails, for risk-managed credit and maximum capital efficiency. Every payout, redemption and crosschain fill is honoured before the originating funds land, so someone has to fund the delay. Sprinter funds it just in time, and is repaid by the settlement itself. 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 November 2025, Sprinter has processed over $400M 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. We call the mechanism Closed-System Embedding: a credit account whose egress is constrained, a policy that governs what the funds can do, and a recovery path that unwinds repay-first.
  • 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.
