Hi Rizki,
Thank you for the kind words and your interest.
OTC Status: The OTC sale is currently
closed. There was an initial offer of 3,000 SOST at $0.20 each, priced below the PoPC
reference value (~$0.22 at the time). However, as more tokens are mined, the reference value adjusts. To be clear: this is a
simulated
reference price based on the tokenized gold I have personally committed to the PoPC program — it is not a market price. SOST is not listed
on any exchange yet, so there is no real market price.
Whatever is obtained from any future sale will go entirely to purchasing more tokenized gold (XAUT or PAXG) to strengthen the protocol
reserve.
Exchange listing: Exchange outreach is planned from June 2026, subject to network stability and sufficient hashrate.
But here's what you CAN do — and it's better than buying: When PoPC activates after block 5,000, you can earn SOST for free just by holding tokenized gold in your own Ethereum wallet. No need to buy
SOST at all. There are two models:
Model A — Autocustody (recommended for crypto holders): You hold XAUT or PAXG in your own Ethereum wallet. You lock a SOST bond as commitment. Random audits verify your gold balance via Ethereum
RPC. At the end of your commitment period, you get your bond back + a reward in SOST.
Example: You hold 0.5 oz XAUT (~$2,350) in your wallet. You lock a SOST bond (25% of gold value). You commit for 6 months. If you maintain
custody, you receive your bond back + up to 9% reward. Your gold never leaves your wallet.
Model B — Escrow (simpler, no audits): You deposit XAUT or PAXG into an immutable escrow contract on Ethereum. You receive SOST immediately — no bond, no audits, no slash risk. At
expiry, you withdraw 100% of your gold.
Example: You deposit 0.5 oz XAUT into escrow for 6 months. You receive up to 3.5% of gold value in SOST immediately. After 6 months, you
withdraw your full 0.5 oz XAUT. You keep the SOST.
Reward rates (Tier 1 — first 25 participants get maximum rates): Model A (% of bond, fee 3%):
1mo: 1% | 3mo: 4% | 6mo: 9% | 9mo: 14% | 12mo: 20%
Model B (% of gold value, fee 8%):
1mo: 0.4% | 3mo: 1.5% | 6mo: 3.5% | 9mo: 5.5% | 12mo: 8%
PoPC Reward Example — Live prices (April 13, 2026) XAUT: $4,702.75/oz | SOST reference: $0.17 (PoPC reference, not market price)
Model A — Autocustody (your gold never moves, fee 3%) Bond required: 6,916 SOST ($1,175)
| Duration | Net Reward | USD value | Return on gold |
| 1 month | 67 SOST | $11 | 0.24% |
| 3 months | 268 SOST | $46 | 0.97% |
| 6 months | 604 SOST | $103 | 2.18% |
| 9 months | 939 SOST | $160 | 3.40% |
| 12 months | 1,342 SOST | $228 | 4.85% |
Result: bond returned (6,916) + reward (1,342) =
8,257 SOST. Your gold stays in your wallet untouched.
Model B — Escrow (no SOST needed, fee 8%) No bond. SOST paid immediately at deposit.
| Duration | Net Reward | USD value | Return on gold |
| 1 month | 102 SOST | $17 | 0.37% |
| 3 months | 382 SOST | $65 | 1.38% |
| 6 months | 891 SOST | $151 | 3.22% |
| 9 months | 1,400 SOST | $238 | 5.06% |
| 12 months | 2,036 SOST | $346 | 7.36% |
Result:
2,036 SOST received on day 1 + your gold returned 100% at expiry.
Which is better? - Model A: You need SOST for the bond, 4.85% return on gold, your gold never moves, risk of slash if you sell gold during
commitment - Model B: No SOST needed, 7.36% return on gold paid immediately, but your gold is locked in escrow until expiry
