We have been quiet, on purpose.
For the past few months, we have been heads down building towards something bigger, and we are excited to reveal where we have landed.
Credit has always carried the same promise: the freedom to act before the money catches up, to do more than your current balance allows, to move on your own terms. It is the thing that gives people and businesses real agency in the financial system, and yet the infrastructure behind it has barely changed in 30 years. Terms are rigid because the technology is rigid, rates are expensive because the plumbing is expensive. The promise was real, but the engine behind it was not.
We have already seen what happens when you rebuild financial architecture from scratch. Stablecoins did it for payments, and overnight they became programmable, global, and structurally cheaper. That same transformation is now possible for credit, and almost nobody is building it.
Sprinter has been focussed on credit for a while, but we started by solving a different problem. We set out to make crosschain transactions seamless, built solver infrastructure, and it worked. The next step was to take it beyond the solver use-case, and the deeper we went into how people and applications actually move value, the more we kept running into the same gap. Every path eventually led back to credit: the missing layer, the primitive that nobody had built yet, and the one that would unlock the most value if someone did.
And so we got to work.
Today we are showing you the first piece of this makeover. A new Sprinter, enhanced from the ground up with new infrastructure, a new identity, and a new level of ambition. All driven by a single conviction.
Credit runs on Sprinter.
This is not just a cosmetic rebrand, it reflects a fundamental shift in what Sprinter is and where we are going.
We are a credit engine. Any application, whether they are building for consumers, businesses, or autonomous agents, can plug in via a single API and offer credit that actually works. That means flexible terms instead of one-size-fits-all, adaptive risk management instead of static rules, and economics that benefit the borrower because the collateral backing every credit line is productive, generating yield that makes credit cheaper by design.
The complexity stays under the hood, and the end user just gets better credit.
The new brand is just the beginning. Over the coming weeks, we will be sharing what we have been building behind the scenes, including a major upgrade to our core infrastructure and something entirely new for consumers.
We are not ready to say more just yet. But if you believe credit is the next great layer of finance to be rebuilt, and that the team that builds the engine will define how it works, then you will want to pay attention to what comes next.
Explore the new Sprinter, and stay tuned for what’s next.

Part I asked what are we pricing when we quote a rate and answered with expected loss, capital, and margin. Part II focused on mechanism and guarantees. The final part of this series focuses on programmable, usage-constrained credit.
The moment you treat guarantees as code, you can underwrite routes and states rather than people. This part develops a concrete architecture for usage‑constrained credit in cross‑chain intent fulfillment, then generalizes it to other closed‑loop loans.
A solver receives a revolving credit line that can only be spent on executing a specific intent. Funds never touch the solver’s externally controlled wallet. At the destination chain, proceeds are swept into a repayment sink that pays the lender first. Only the surplus, if any, can leave the system. Misuse is structurally impossible; underwriting focuses on route risk.
Route risk in PD/LGD/EAD terms
An intent is posted and claimed (see Fig. 2). The solver locks a bond. The credit vault authorizes the source‑chain router to fund the route, tagging the bridge transfer so it can only land in the destination‑side sink. The destination router can call only whitelisted venues. When the trade completes, the sink retains principal, accrued interest, and protocol fees, and emits an attestation back to the source. Upon confirmation, accounting rolls forward and any surplus is released to the solver or shared with the user. If anything fails, timeouts and partial‑repayment rules determine how bonds are seized and how insurance funds step in.
No user pre‑funds the destination; the protocol fronts capital. The rate charged is the price of route risk: bridge failure, stale oracles, thin books, message delays. Loss given default is bounded by the repayment sink, by the solver’s bond, and by an insurance pool. Exposure at default is the funded notional during execution. Tightening allowlists, reducing timeouts, and sizing bonds cheapen the rate by cutting expected loss.
Once you have repayment sinks and allowlisted routers, many “closed‑loop” credits fall out: merchant payouts where settlement currency must be converted along the way; RWA vaults where incoming cash flows must amortize a facility before any dividends are paid; programmatic capex loans that can buy only specific on‑chain inventory. The technology is the same; only the whitelists and oracles change.
Code cannot erase risk; it only reshapes it. Priority becomes a matter of contract logic rather than contract law. Solvency depends on buffers that reflect finality lags and market depth at the destination. Reversibility is limited to what the mechanism allows; once a sink pays out, the system needs a credible path to recover mis‑routed funds. These constraints are not bugs—they are the design surface.
We started with rates as prices of risk, moved through mechanisms for moving value while we wait, and ended with guarantees that can be expressed as law or as code. The practical takeaway is simple: separate pricing from plumbing. Price the thing you actually risk (people, positions, routes); then pick the lightest mechanism that keeps obligations safe—ideally one that nets and batches until the boundary, backed by guarantees you can verify. As more cashflows originate on programmable rails, expect guarantees to migrate from paper to code and for non‑deliverables, repayment sinks, and risk engines to become standard parts of product design.

Join us to shape the future of onchain credit.
Sprinter Stash’s app will officially go live tomorrow at 12pm CET, unlocking a new way for DeFi participants to earn rewards by contributing USDC liquidity to Sprinter Stash.
But this isn’t just about staking and waiting. It’s a chance to be part of the next wave of crosschain liquidity infrastructure — and earn real rewards for doing so. For those who jump in early, the benefits get even better.
Sprinter Stash is a dynamic liquidity layer designed to power crosschain execution within the Sprinter protocol. Liquidity providers deposit USDC into the protocol through an intuitive interface, selecting the chain they want to deposit from and locking their funds for a chosen duration.
Once deposited, Stash takes over, algorithmically distributing and rebalancing liquidity across supported chains based on live solver demand. This allows solvers to borrow credit on destination chains without collateral, enabling instant, capital-efficient execution across the ecosystem.
When a transaction is filled, the borrowed funds are repaid on the source chain. From there, profits flow back to LPs, who earn from a combination of solver fees, passive yield, and Stash points.
It’s liquidity that works harder — and smarter.
When Stash goes live tomorrow, the race to rewards begins! We will be kicking off a series of events as part of the Sprinter Olympics, where you can earn Stash Points, a new rewards system that tracks your contributions across the Sprinter ecosystem.
The first event will be The 100M Stash, where you can earn Stash Points by depositing USDC into Sprinter Stash and locking your liquidity for a chosen duration. Stash points will be distributed 1:1, for every $1 staked, you receive 1 Stash point.
More ways to earn will be revealed in the coming weeks, in addition to the leaderboard going live soon - so keep stacking points and we’ll see who’s leading the race.
Sprinter Stash rewards liquidity providers with points, and yield that scales based on how long you lock your funds. The longer you commit, the higher your multiplier, starting at 0.4x for a 3-month lock, up to a generous 2.2x for a 12-month commitment.
And for early adopters, there’s an additional reason to act fast: deposits made within the first 48 hours of each milestone unlock a 100% SPRNT bonus on your USDC deposit, on top of your regular rewards. No extra steps required — just show up early, and your bonus will be automatically applied.
To kick things off, we’re rewarding our earliest Stashers with both base multipliers and bonus points.
