Stablecoin vs On-chain settlement: what is the difference?
A stablecoin is the token, built to hold a stable value such as one US dollar. On-chain settlement is how it moves: a transaction recorded on a blockchain, final once the network treats the block as final.
| Stablecoin | On-chain settlement | |
|---|---|---|
| In one line | A stablecoin is a crypto token designed to hold a stable value, usually by tracking one currency such as the US dollar and holding reserve assets to back it. Payment firms use dollar stablecoins to move and hold value on blockchains outside banking hours. | On-chain settlement is the transfer of a token, such as a stablecoin, by a transaction recorded on a public blockchain, which counts as settled once the network treats the block as final. Finality time depends on the chain and on how many confirmations the receiving party requires. |

How they work together
Stablecoins settle at weekends and overnight, which is why payment companies use them to fund corridors outside banking hours.
Where Polynopsis fits
Polynopsis reads stablecoin wallets through their public addresses, read-only, so stablecoin balances sit in the same position as fiat balances at banks and partners.
Polynopsis keeps a stablecoin transfer in flight until it is confirmed on chain and credited, so the position never counts it as usable early.
