Sprinter

Sprinter, built by the ChainSafe team, lends pooled capital to cross-chain solvers so they can fill orders without pre-funding, while Stash manages LP capital across chain pools, rebalancing and netting rails and passive lending such as Aave. The solver-credit controls constrain use but do not let the depositor enforce a fixed advisor-approved venue allocation after deposit. That continuing portfolio management is more fundamental than the approximately $1.20M TVL observed on 2026-08-16, so the version-1 delegated-allocation dossier rejects Stash V1 at zero.

Review triggers: events that reopen the verdict
• Enforces an immutable client-specific allowlist and limits for solvers, chains, rebalancing rails and passive-yield venues, with debt, losses and allocations independently observable
• Demonstrates a proposed-size stressed redemption for the selected lock term through every active solver and strategy exposure without new subscriptions or manager substitution

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism applicability

Sprinter Stash LPs deposit USDC on Base and receive spUSDC-LP. The pool supplies usage-constrained, zero-collateral credit to allowlisted cross-chain solvers, while capital can earn base yield through Aave. Sprinter states that liquidity is automatically managed across supported-chain pools using rebalancing and netting protocols. The depositor receives one claim while the system changes credit, venue and chain exposure after deposit, directly satisfying the shared delegated-allocation dossier.

Current observation and lifecycle

The DefiLlama protocol API read on 2026-08-15 classified Sprinter as Yield and reported approximately $1.19M on Base. Sprinter announced the live Stash app in November 2025 and now documents a broader Sprinter Credit V2 alongside Stash Solver Credit V1. This record remains scoped to the Base Stash liquidity measured by DefiLlama, not every destination chain or every newer credit product.

Control and exit applicability

Stash uses MPC validation, allowlisted routers, restricted transaction use and repayment-sink priority to constrain uncollateralized solver credit, but LPs still depend on solver repayment, MPC operation, contracts, Aave and cross-chain execution. Current materials describe no-lock deposits as well as 3-, 6- and 12-month lock choices. Redemption therefore depends on the selected lock and available pool liquidity rather than a guaranteed immediate par exit.

Why the class rule decides

MPC validation, allowlisted routers and repayment priority bound solver actions, but they do not freeze the LP portfolio to mandate-approved venues and caps: the system chooses solver credit, passive yield and cross-chain inventory paths after deposit. The version-1 delegated-allocation dossier therefore controls regardless of size. Reopen only if a named Stash pool enforces an immutable client-specific allowlist and limits, publishes independently verifiable solver, chain, venue, debt and loss exposure, and demonstrates proposed-size exits for every lock choice without new subscriptions; compare with direct approved lending positions.

Class rule

The delegated allocation class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
