Use USDC on Monad — without ever buying MON

Monad looks like every other new network: to do anything, people assume you first need to go buy its native coin, MON, just to pay a fee.

You don't. Not with Sigma9.

Hold USDC, send USDC — that's all Monad asks

Sigma9 treats Monad like every other network it supports. Your existing wallet works there with no extra setup. You hold USDC, you send USDC, and the fee comes out of the same USDC — never MON.

Move USDC in and out of Monad freely

Need to bring USDC onto Monad, or move it somewhere else? Do it whenever you like. The fee for moving between networks is paid in USDC too — there's no MON to buy first, on either side.

Same simple wallet, same keys on your device

Nothing changes about how Sigma9 works just because you're on Monad. One balance, one Send, one Receive. Your keys stay on your device the whole time — self-custody, no account, no server holding your funds.
