How SPA Works

The mechanics behind systematic, risk-gated DeFi yield management.

What SPA Does

SPA is an autonomous yield optimizer for onchain stablecoins. It runs daily scans of whitelisted DeFi lending protocols, applies a deterministic risk gate to every proposed allocation, and rebalances between protocols when drift exceeds a threshold. There is no discretionary human override in the execution path. There is no LLM in the execution path.

What SPA Does Not Do

Does not use leverage (Core/Preserve strategies)
Does not use unaudited protocols
Does not bypass RiskPolicy gates
Does not rely on LLMs for execution decisions
Does not hold non-stablecoin assets
Does not make discretionary overrides

Daily APY Scan

Every day, SPA executes a full scan of supported protocols to collect current yield data.

Data source DeFiLlama Yields API — primary APY feed
Adapters Dedicated read-only adapter per protocol
Sanity check APY bounds [2%, 40%] — anything outside triggers a flag
Schedule Daily cycle (automated via scheduler)
Output Timestamped JSON log per cycle

Protocol Adapters

Each supported protocol has a dedicated read-only adapter. Adapters normalize APY, TVL, and pool metadata into a standard format for the allocation engine. No write access at scan stage.

RiskPolicy v1.0 Parameters

A deterministic, hard-coded gate. No human, no AI, no strategy can override these parameters.

Parameter Value
TVL floor $500M minimum
Per-protocol cap 25% of portfolio
Tier 1 minimum allocation 60%
Cash buffer 5%
APY lower bound 2% (avoid dust yields)
APY upper bound 40% (sanity cap)
Monthly drawdown kill switch −5%
Max single-asset concentration 40%

Risk-Gated Rebalancing

Rebalance triggered when allocation drift exceeds threshold
Each rebalance proposal checked against full RiskPolicy
If any gate fires → rebalance blocked, reason logged
Blocked rebalances visible in Dashboard → Risk Blocks tab
Human cannot override blocked rebalance in paper trading phase

Strategy Tournament

Multiple strategies compete on risk-adjusted performance. The tournament ensures only the best-performing approach gets capital allocation.

Participants

Multiple strategies run in parallel on paper
