Stablecoin

A stablecoin is a token engineered to hold a constant value, almost always one US dollar. The dominant design is fiat backing: an issuer holds dollars and dollar-equivalent reserves and issues one token per dollar held, redeemable back into currency. The token's stability is therefore only as good as the reserves and the redemption mechanism behind it.

In trading, stablecoins serve as the measuring stick and the safe harbor. Quoting volatile assets against a stablecoin makes prices legible in dollar terms, and moving into a stablecoin parks value without leaving the ledger. In AMM systems they have an extra role: a pool pairing a volatile asset with a stablecoin gives that asset a direct dollar market, and pool-implied USD prices flow from such pairs.

On Canton Network, USDCx is the USDC-backed stablecoin OneSwap lists, and its pools anchor dollar pricing across the catalog. One caution transfers from every other chain: a stablecoin in an AMM pool still trades like any pool asset, so large swaps against thin reserves can execute away from one dollar even when the peg itself is sound.
