The design choice
DracmaSaleV2 — the public-sale contract, rehearsed on Sepolia — accepts payment in USDC (through purchaseWithUsdc) and in ETH. The rehearsal uses Circle's USDC on Sepolia; the eventual mainnet sale would use USDC on Ethereum mainnet.
Why USDC
Because it is where prospective buyers already hold dollars. A sale priced at $0.65 needs a dollar-denominated payment rail; USDC is the most widely held one on Ethereum. That is the whole reason.
Why not DUSD
DUSD is EmpoorioChain's native stable asset — on the chain whose token is being sold, on a testnet, with no reserve. A buyer cannot hold DUSD before holding DMS, and the sale exists to distribute DMS. The sale's payment leg therefore lives on Ethereum; the delivery leg lives on EmpoorioChain (native DMS via Merkle claim).
Why USDC and not USDT
An earlier version of the sale's frontend said USDT in several places — the widget, the translations in five languages, an investor page. The contract used USDC. The September 2026 audit found the mismatch; the canonical file says pay: ['ETH','USDC'] and the site now reads from it. Details in the companion post.
What this is not
A partnership. Accepting a public ERC-20 as payment requires no agreement with its issuer, and none exists. The page this replaces announced a partnership with the stablecoin's issuer to bring it to another chain. Nothing of the kind has happened here, and the distinction matters: an ecosystem that lists a company as a partner because it uses that company's public token is making the exact class of claim this site removed in September.
What buyers should verify
The contract's usdcToken() address against Circle's published USDC address on the relevant network. On Sepolia it is 0x1c7D4B196Cb0C7B01d743Fbc6116a902379C7238, and the contract registry records that usdcToken() returns it. A sale contract pointing at any other "USDC" is not this sale.
Based on CONTRATOS_EVM.json (DracmaSaleV2), TOKENOMICS.json (venta.pay) and the September 2026 site audit.
