APR Math & Mining Partition
Units:
- 1 XLM = 10,000,000 stroops
- Contract values use i128 stroops
Top APR:
- Fetched from Algolia
ratingReplicaIndex(desc by APR) - Escrow allocation (does not exceed 0.3 XLM) =
min(1 XLM * topAPR% / 100, 0.3 XLM)
Mining partition on 1 XLM:
- Escrow invest:
escrow = min(1 * apr% / 100, 0.3) - Remaining:
rem = 1 - escrow - Issuer payment:
pay = rem / 2 - User equity invest:
equity = rem / 2
Both escrow and equity invests are converted to stroops (× 1e7) before calling invest.
Example:
- topAPR = 25%
- escrow = min(1 * 0.25, 0.3) = 0.25
- rem = 0.75
- pay = 0.375
- equity = 0.375
- invest calls receive 2,500,000 and 3,750,000 stroops respectively.
