# Boosted Promotion

Boosted APR during Presale up to 150%

During the presale period, all Yield Account deposits earn the following tiered rates. Interest is calculated as APR, and paid weekly directly to the user’s wallet.

| Deposit (USD value) | Boosted APR | Weekly Payout (min – max for tier)        | Total Earned in 56 Days (min – max) |
| ------------------- | ----------- | ----------------------------------------- | ----------------------------------- |
| $25 – $250          | 15%         | $0.07 – $0.72                             | $0.56 – $5.76                       |
| $250 – $1,000       | 30%         | $1.44 – $5.77                             | $11.52 – $46.16                     |
| $1,000 – $2,500     | 60%         | $11.54 – $28.85                           | $92.32 – $230.80                    |
| $2,500 – $5,000     | 75%         | $36.06 – $72.12                           | $288.48 – $576.96                   |
| $5,000 – $10,000    | 100%        | $96.15 – $192.31                          | $769.20 – $1,538.48                 |
| $10,000 – $25,000   | 125%        | $240.38 – $600.96                         | $1,923.04 – $4,807.68               |
| $25,000+            | 150%        | $721.15+ (e.g., $50,000 → $1,442.31/week) | $5,769.20+                          |

Example (during presale):

\
A $10,000 deposit at 125% APR earns $10,000 × 1.25 ÷ 52 ≈ $240.38 per week. Over 8 weeks, that totals $1,923.
