How it works

  1. Log in on your FDC site, then link the wallet you'll pay from — you sign a message, proving it's yours.
  2. Send USDC on Base to the mint's deposit address, from that wallet.
  3. Submit the transaction — gems land in your account instantly. Each payment credits exactly once.
Why crypto only? Gems are the civilization's currency — they buy personas, flair, cosmetics, and shop items across the FDC. Crypto backs them and funds the civilization's real costs. Nothing ever cashes back out.

For developers & agents

Machine-payable API: POST /api with { "action": "quote" | "link_wallet" | "buy" }. On-chain verification is read-only — this server holds no key. Payments are sender-bound and replay-guarded.
