Proof of Personal Custody
Bond your SOST to prove custody of real gold (XAUT/PAXG)
How It Works
1. You hold XAUT or PAXG in your Ethereum wallet
2. You lock a SOST bond (12-30% of gold value) on the SOST chain
3. Random audits verify your gold balance via Ethereum RPC
4. If you maintain custody: bond returned + reward (up to 22% APR)
5. If you sell your gold: bond is slashed automatically
Your gold NEVER leaves your wallet. Only the SOST bond is at risk.

| 6 months | 9% | 18% |
| 9 months | 15% | 20% |
