Stablecoins use different mechanisms to target a reference value. The mechanism determines which evidence and stress points deserve attention.

Reserve-backed structures

These designs rely on identified reserve assets and an operational path for issuance and redemption. Reserve composition, custody, attestations and legal claims shape the risk picture.

Crypto-collateralized structures

Overcollateralized systems use on-chain assets and liquidation rules. Their resilience depends on collateral quality, oracle design, market liquidity and smart-contract operation.

Algorithmic structures

Some designs adjust supply or incentives without a conventional reserve pool. They can be especially sensitive to confidence, reflexive selling and weakened redemption expectations.
