Common questions: USDC Optimism → SNX

What rate does USDC Optimism to SNX run at?
As of Sep 30, 2026 10:30 it is 1 USDC Optimism = 3.9074 SNX. The figure updates on its own, and the calculator always shows the current one. On the market that is around $0.999169.
What amounts does USDC Optimism → SNX accept?
From 100.67 to 10,000,000 USDC Optimism per order. The floor is roughly $100.65.
Why can I not swap less than 100.67 USDC Optimism?
The network fee and the handling do not depend on the amount. On a transfer below 100.67 USDC Optimism they eat a noticeable share of it, and the swap stops making sense for either side.
Is anything charged on top of the rate?
No. The payout is already worked out at the rate in the calculator. Separately you pay only the network fee for sending USDC Optimism, and the blockchain takes that one.
How long does swapping USDC Optimism for SNX take?
The clock starts with confirmations: as soon as Optimism confirms your transfer, the order goes out for payout with no operator involved. After that the timing is set by how busy the network is — which is the difference between quick and instant.
Which network will SNX arrive in?
Synthetix arrives in its own Synthetix network — a plain SNX address is all you need.
What happens if the rate moves while I am paying?
Nothing: the rate is locked in the order and holds for as long as the order is alive. It is recalculated only if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.
What did the USDC Optimism to SNX rate do over the month?
Over the month, minus 17.83%: a low of 3.7145, a high of 5.0336, an average of 4.5075 SNX per 1 USDC Optimism.
Can I swap back, SNX for USDC Optimism?
