Once USDG arrives in your wallet, it behaves like any other stablecoin on Solana.
You can:
Hold it as a relatively stable, dollar-pegged asset if you want to reduce exposure to SOL volatility on your rewards.
Send it to other Solana addresses, including friends, other wallets you control, or exchanges.
Trade or swap it for other tokens on integrated DEXs or CEXs that support USDG.
Potentially use it in DeFi protocols (lending, LP positions, etc.) that explicitly list USDG as a supported asset.
Important:
Marinade itself does not manage redemptions or off-ramps for USDG.
Any conversion to fiat or other chains/tokens depends on services provided by exchanges, bridges, or the issuer’s partners.
You should always verify which platforms support USDG and what their fees and risks are before using them.
