#StablecoinPayments
Fiat-backed: Supported 1:1 by traditional currency reserves such as the USD (e.g., USDT, USDC)
2. Commodity-backed: Tied to physical assets like gold
3. Crypto-collateralized: Secured by excess reserves of other cryptocurrencies
4. Algorithmic: Utilize smart contracts to regulate supply and demand
For accounts payable, fiat-backed stablecoins are the most widely used due to their price stability and the transactional efficiency offered by blockchain technology.
