Yield Alpha

Earnings use simple pro-rata math (no compounding in v1):

earnings = principal * (apyPct / 100) * (horizonDays / 365)

Alternative APYs come from live dashboard market data (`rate.currentPct`, falling back to `basePct`). Manual current APY is user-entered.

Switching costs are labeled estimates: exit fee, entry fee, gas by chain, time cost during transfer, and optional early-exit penalty. Override inputs when you know exact protocol terms. Estimates never silently present as measured fees.

grossAlpha = altEarnings - currentEarnings
netAlpha   = grossAlpha - switchingCostUsd

Alternatives are ranked by net Yield Alpha in USD. Sponsorship never changes this order.

• MOVE when net Alpha clears the larger of $25 or 15 bps of principal, and alternative durability is at least 40/100, without an unusually high outlier with weak history.
• STAY when net Alpha is negative beyond the larger of $10 or 5 bps of principal, or the alternative has no usable rate.
• WATCH for thin edges, weak durability, or insufficient history.

Durability is derived only from existing dashboard rate history fields: stability score, durability enum, history coverage, deviation from 7d/30d medians, decay state, outlier state, and stability label. Insufficient history caps the score at 35.

Wallet scan is read-only and never requests a signature. The public RPC adapter reads known Aave aUSDC and Morpho MetaMorpho USDC vault balances on Ethereum, Base, and Arbitrum. It does not invent balances. A live Yield.ly APY is attached only when exactly one pooled market matches an Aave aUSDC balance. Morpho vault balances stay without an APY, because a generic Morpho USDC row is not that vault. Other chains and tokens stay on the manual calculator.

Settled MOVE outcomes are not archived. The track record page says so, and it does not show a return.
