1. Pick a currency
USD, EUR, JPY and ten more.

USD, EUR, JPY and ten more.
Name, ticker and a buffer of at least 100 USDG.
1 $EURO = €1, fixed at launch.
The token and its vault deploy together.
At the signed FX price. 0.10 % each way, paid into the buffer.
Mint
USDG in, $EURO out.

Redeem
$EURO in, USDG out.

Wallets, apps and markets see one fixed target.
Launched as 1 $EURO = €1.
Nobody can change it later.
One token tracks one currency, for good.










A browser wallet on Robinhood Chain testnet (46630), a little test ETH for gas and at least 100 USDG for the locked buffer. Then pick a currency, a name and a ticker, and launch.
No. Tickers are unique per factory, first come first served, so nobody can launch a second, fake $EURO.
A signed price. The server reads two free FX sources (ECB via Frankfurter and open.er-api) and refuses to sign if they differ by more than 1%.
0.10% to mint and 0.10% to redeem. Every fee goes into that token’s buffer; there is no protocol revenue on testnet.
The creator seeds a locked buffer of at least 100 USDG that nobody can ever withdraw. It covers the currency rising against the dollar, grows with every fee, and lets the vault back mints down to the 105% floor.
Not yet. Stablecash runs on Robinhood Chain testnet (46630) first. Mainnet needs a separate go-ahead, a real USDG buffer and a legal check, so there is no mainnet date yet.
