ERC721-C / ERC1155-C — Creator Token Standards. Transfer validator enforces royalty collection.

F

Facilitator — off-chain x402 service that verifies + settles USDC authorizations. cc0.company uses the Coinbase CDP facilitator for v2.

Replicate — AI model hosting service. Managed Agent Services run on Replicate.

Royalty BPS — secondary-sale royalty rate set at deploy, capped at 1000 (10%). Enforced via ERC721-C validator or EIP-2981.

S

SalePhase — mint window with its own price, payment token, merkle root, supply cap.

SSTORE2 — store data as bytecode of a minimal contract. ~200 gas/byte vs SSTORE's ~625. Used for ERC1155 artwork chunks.

Stripe onramp — card-to-USDC onramp embedded in the BuyModal. Buyer pays with card, platform onramps USDC, standard USDC mint flow.

T

Transfer validator (ERC721-C) — onchain gatekeeper enforcing royalty collection. cc0.company allowlists OpenSea Conduit + Seaport 1.6.

V

variantHash — keccak256 of buyer's variant choice (size, color) submitted at claim. Stored on chain via claimProduct(tokenId, variantData).

X

x402 — HTTP payment protocol. 402 status code challenges unauthenticated callers; USDC transferWithAuthorization settles. cc0.company uses v2 (Coinbase CDP facilitator) for agent services.

Z

Zora — token launchpad. cc0.company integration: smaller LP cut than Clanker BUT token paired with $CC0COMPANY + 1% supply airdropped to creator wallet.
