Stablecoin on-ramp vs Stablecoin off-ramp: what is the difference?
An on-ramp turns fiat into stablecoins; an off-ramp turns stablecoins back into fiat and pays it out. A stablecoin-settled payment usually uses both: on-ramp in the sending market, off-ramp in the receiving one.

How they work together
Between the two ramps the money is on-chain, which makes it easy to see but easy to forget in a fiat-only treasury view. Both legs belong in one position.
Where Polynopsis fits
Polynopsis reads stablecoin wallets through their public addresses and exchanges and custody platforms through read-only API keys, so stablecoin balances sit in the same position as fiat.
Polynopsis follows stablecoin balances on-chain and fiat balances at partners in one position, so the team sees money on both sides of an off-ramp, and in between.
