Minting policies can only control mint/burn operations, not token transfers. If we want to freeze transfers (e.g., as for a regulatory pause/freeze event), we must make the token a native token with a spending validator.
Plutus policies are immutable. Any change to freeze will yield a new currency symbol. You cannot freeze/unfreeze an existing token this way. This is a serious consideration for stablecoin controls.
● If you want freeze to be updatable, consider state management via a reference UTXO (“state token” or similar technique).
● Alternatively, model the freeze control in an off-chain app that only mints via script interactions, considering the current freeze state.
Cardano chose a different path: native & over-collateralized stables
Instead of rushing centralized stables, Cardano supported:
- DJED (algorithmic, over-collateralized)
- USDA (fiat-backed, regulated, Cardano-native)
- iUSD and other ecosystem stables
This aligned with Cardano’s philosophy:
Minimize systemic risk before scaling liquidity.
However, it also meant slower adoption compared to chains that imported USDT early.
The situation is changing (important)
Today, Cardano now has:
- Better DEX throughput (Hydra, Mithril, Plutus v3)
- Growing institutional tooling
- More active DeFi builders
- Regulatory-aligned stablecoin projects
That’s why:
- USDA exists
- Cross-chain USDC bridges are being explored.
- Circle has publicly acknowledged Cardano as a serious chain (but no launch commitment yet)
Bottom line:
Cardano doesn’t lack tier-1 stablecoins due to ideology or failure; it prioritized correctness, security, and decentralization, whereas issuers prioritized speed, liquidity, and revenue.
