A Reactive Yield Automation built as a Uniswap v4 hook. When your USDC exits its range, capital routes to Compound V3 within the same block — recalled just-in-time before the next swap executes. Zero off-chain infrastructure. Each position is an on-chain NFT.
PROTOCOL FEATURES
Every component eliminates idle capital and maximises yield. Autonomously, trustlessly, on-chain.
Idle capital automatically flows to Compound V3 the moment your position exits range. No decisions, no clicks, no keeper bots — the Reactive Network fires within the same block.
Built natively into Uniswap v4. Deposit USDC, earn yield. Works with every wallet and every Uniswap tool — no new UI to learn, no additional contracts to manage.
RangeMonitorRSC on Reactive Network subscribes to your hook's events and fires callbacks in the same block — JIT recall returns capital before the next swap executes. No off-chain infrastructure.
Every liquidity position is a transferable ERC-721. Position state, yield accrued, and routing history — all on-chain, all queryable.
APYVerifier rejects any source reporting more than 2x its trailing TWAP before capital moves — a compromised adapter cannot drain the pool. Contracts are unaudited; verify the logic in libraries/APYVerifier.sol.
Swap fees scale with yield utilisation — when more capital is earning yield, the fee rises to compensate LPs for reduced pool depth. Computed on-chain by DynamicFeeModule.
SYSTEM ARCHITECTURE
Every claim on this page is backed by on-chain contracts, passing tests, and verifiable provenance.
THE PRIMITIVE UNDERNEATH
IdleCapitalYieldModule is an abstract Solidity contract providing reusable idle-capital yield routing for any Uniswap v4 hook. Inherit it to get position tracking, four callback hooks, and RSC-triggered yield routing — zero product coupling.
contract MyHook is IdleCapitalYieldModule {
constructor(IPoolManager pm, YieldRouter router, address asset, address owner)
IdleCapitalYieldModule(pm, router, asset, owner)
{}
}Proves the module works with zero StableStream-specific code. Inherit, deploy, route. 11 tests verify position tracking, access control, and yield routing — all independent of the reference implementation.
contract MinimalHook is IdleCapitalYieldModule {
constructor(
IPoolManager _poolManager,
YieldRouter _yieldRouter,
address _usdc,
address _owner
) IdleCapitalYieldModule(_poolManager, _yieldRouter, _usdc, _owner) {}
}Reactive Network RSC fires callbacks within the same block — no bots, no cron jobs, no oracles.

What you would have to reimplement from scratch — and what IdleCapitalYieldModule gives you for free.
| You would build | IdleCapitalYieldModule gives you |
|---|---|
| Position tracking (open, close, query by owner) | 3 public functions, 1 struct, 8 events |
| Range detection (tick math, beforeSwap / afterSwap) | 4 hook callbacks, in-range / out-of-range events |
| Yield routing (deposit to external protocol, track, recall) | routeToYield / recallFromYield, YieldAccounting |
| Dynamic fee scaling (yield ratio → swap fee) | getDynamicFee() |
| Rate limiting (per-block caps, cooldown, JIT bypass) | POSITION_COOLDOWN_BLOCKS, MAX_CALLBACKS_PER_BLOCK |
| Automation (event → callback chain) | RangeMonitorRSC — deploy once, subscribe automatically |
| APY safety (anomaly detection, risk scoring) | APYVerifier (TWAP), RiskEngine |
| Multi-source routing (Compound, Aave, native staking) | YieldRouter with IYieldSource adapters |
| Gas optimization (EIP-1153 transient storage) | TransientStorage library |
| Tests against edge cases and security invariants | 161 tests across 11 suites |
