Sprinter Liquidity
Sprinter Liquidity is a credit-based liquidity protocol that connects stablecoin LPs with the actors who need funding for a settlement delay — crosschain solvers filling intents, and asset issuers offering instant redemptions and subscriptions on assets that settle T+X. It bridges the gap between passive capital and high-frequency demand for short-duration credit.Two ways to access it
Solve RFQ is the path for asset issuers, wallets and applications: you get a firm quote with liquidity reserved behind it, plus a transaction to send. Sprinter builds the order and fills it. The Liquidity API is the path for crosschain solvers running their own fill infrastructure: you get a borrow quote and an MPC-signed authorization, and you run the fill and settlement yourself. See the Integration Guide.Issuing an asset with a settlement delay? Go to the Asset Issuer quickstart for onboarding and the two runtime calls, and Pricing & Credit Facilities for what a fill costs and whether you want shared liquidity or a dedicated facility.
Why Sprinter Liquidity?
For Liquidity Providers
Sprinter Liquidity is for liquidity providers looking for an attractive yield opportunity based on a new DeFi primitive:- High Yield & Low Risk: Sprinter Liquidity utilizes multiple yield sources to maximize capital efficiency and returns: LPs earn from service fees paid by solvers to access credit as well as proven passive yield sources (such as lending protocols) ensuring low risk.
- Secure & Credible: MPC-secured multi-party threshold signing, risk mitigation mechanisms, and smart contract audits by Veridise and Spearbit/Cantina make Sprinter Liquidity a secure platform. Built in partnership with ChainSafe, a team with 7+ years of industry expertise across core protocol development, standardization/EIPs and security audits/council work.
For crosschain DeFi
Sprinter Liquidity enables capital-efficient crosschain execution by removing the need for pre-funded liquidity pools or collateralized loans. Liquidity is automatically managed across chains via a variety of rebalancing and netting protocols. At launch, Sprinter Liquidity initially supports solvers filling orders in:- Across
- LiFi Intents
- Mayan Finance
- Rhinestone
How Sprinter Liquidity Works
- Liquidity Providers deposit USDC on Base from any chain into the protocol’s liquidity hub - Receiving spUSDC-LP tokens in return. Liquidity is then managed across the pools on supported chains.
- Solvers access liquidity instantly, without collateral – Solvers execute their fills through Sprinter Liquidity. After a fill is completed via credit, Sprinter receives the deposited funds on the source chain, repaying the credit and keeping profits for LPs and solvers. It works as a closed credit system — Closed-System Embedding — where the MPC validates all intents to be filled and ensures credit will be repaid.
- LPs earn blended yield – Yield combines a passive baseline from lending protocols such as Aave with the borrow fees paid for access to credit. Capital is deployed where it is needed and earns the baseline while idle.
- Once fills are completed, Sprinter receives funds on the source chain, repays the credit, and distributes profits to LPs and solvers.
- Destination Networks - Base, Arbitrum, Optimism
- Tokens - DAI, ETH/WETH, USDC, USDT, WBTC
- Protocols - Any EVM crosschain bridge/swap protocol such as 1inch Fusion+, Across, Debridge Liquidity Network, Everclear, Mayan.Finance with many more upcoming
- Rebalancing/Inventory Management - CCTP, native Bridges, Everclear
How Sprinter Liquidity Enables Zero-Collateral Loans
Sprinter Liquidity enables solvers to borrow liquidity with near zero collateral, and achieves this through a series of mechanisms below:1. Approved Solvers
On launch only approved solvers can access credit. These solvers:- Undergo screening and onboarding by the Sprinter team
- Must use authenticated API keys tied to their accounts
- Are rate-limited and monitored to ensure responsible usage
- Fill accuracy and repayment behavior
- Volume solved and protocols interacted with
- On-chain and off-chain repayment events
2. Transaction-Level Guarantees
Each fill is validated against the user’s original intent using:- Verified source deposits (e.g. via Across)
- MPC-signed authorization signatures
- Controlled function execution (via calldata)
3. Protocol Guardrails & Limits
Sprinter enforces:- Per-solver daily limits (to minimize exposure)
- Per-transaction liquidity caps
- Circuit breakers triggered by irregular repayment behavior
- Slashing (or bond requirements) for higher-risk integrations
4. Solver Risk / Repayment
Liquidity pools initiate the execution, not the solver. The solver does not pull funds itself, but merely instructs the pool and as such never custodies capital. There are no scenarios where a solver can “not execute” or misdirect funds.5. Liquidity Provider Risk
Sprinter Liquidity is a closed credit system with controlled flows, so solvers cannot lose LP funds. The remaining risks are the same as any DeFi protocol: Security risks in the protocol itself and in the protocols we use (e.g. Aave). We only integrate with partners who meet strict security standards and have strong audit histories as ourselves.Fees
Sprinter Liquidity handles crosschain liquidity fills. Revenue is generated from the spread between the amount the user deposited on source and the amount provided on the destination.Revenue Components
- Fill Revenue: Amount user deposits on source - amount sent to user on destination
- Borrow Costs: Cost of liquidity borrowing and crosschain repayment.
- Solver Costs: Gas fees and execution costs fronted by solvers.
Profit Calculation
Monthly Distribution
- Withdraw raw profits from liquidity pools.
- Deduct solver gas costs.
- Distribute monthly fill profits to:
Initial fee split is reviewed monthly by governance.
