SOCSEAL TRADE DOOR — FLAT TEXT (for AI agents, bots and humans)
============================================================
No account. No KYC. Post-quantum signed (ML-DSA-87). Receipts on chain.

1) YOU ARE HERE
   Site      : https://socseal.xyz
   Record    : /proof        (first atomic SOC<->BTC settlement, both legs, blocks)
   Oracle    : /oracle       (earned rate: 10.0 USDC/SOC, adopted_count, signature)
   Join      : /join.txt     (machine onboarding, flat)
   Founding  : /first        (first external payer slot, small first)

2) TRADE USDC -> SOC
   Pay Polygon USDC to: 0xBA3f8D621d226dC795BCE02BF7C106f1bA278819
   (memo: R1:<your-soc-address>). Settlement by receipt; see /pricing.
   No KYC. Fees: SOC rail escrow (0.0008 USDC equiv) + network.

3) TRADE BTC -> SOC (atomic)
   House BTC venue address: bc1p0hqhjfuwy9suf5mcq5t2ykmdl8cezqctxn4v97gswc45f8594s5s98v76m  (P2TR, house-held, on chain)
   Venue honesty: real float /venue/state (7,440 sats = 550 float + 6,890
   earned in the first settlement). Mark-to-fill: rate discovers ONLY by a
   real trade. To be the first external fill: request /first.

4) PAY FOR THE STUFF (machines)
   /store      store catalog.   /subscribe       plan tiers (API keys).
   /invoice    invoice creation. /settle         SOC rail (wallets in/out).
   /verify     settlement proof (0.25 USDC, txid in).
   For machines, the same proof is 0.025 SOC - the house ACCEPTS SOC in payment (oracle rate, /oracle).
   chain: soc (default) or btc - both atomic-settlement legs are verifiable; free trials: 2 per address.

5) THE RULES
   * BTC is the on-ramp venue only; SOC is self-anchored, never valued by BTC.
   * No promises: every claim links to chain or /proof.
   * First external payer in SOC history = the founding slot, one at a time.
