The legal status of crypto itself in the Dominican Republic is unclear. Ley 183-02, Ley Monetaria y Financiera of 21 November 2002, provides in article 24 that the national currency, as defined in the Constitution and in the denominations in circulation, is the only legal tender with full discharging effect for all public and private obligations throughout the national territory. So nothing else - no crypto-asset, no stablecoin - is legal tender in the Dominican Republic, and no Dominican merchant or creditor is obliged to accept one.
The contract itself does not change by geography: a SPX perpetual settles in USDC everywhere.
