What is a stablecoin? USDT and USDC, explained
Updated 2026-08-14
A stablecoin is a digital currency designed to hold a steady value, usually pegged one-to-one to a currency like the US dollar. USDT and USDC are the two most widely used. This guide explains what that means in practice.
Pegged, not volatile — with a worked example
Unlike bitcoin or ether, whose prices move constantly, a dollar-pegged stablecoin aims to stay worth one dollar. That makes it usable as money — for holding value, sending, and settling a price — rather than as a speculative asset.
The target is not a guarantee. A stablecoin can trade above or below its reference value, and issuer, reserve, liquidity, network and legal events can affect access or redemption. That is why a dollar-denominated unit should not be described as insured cash or risk-free savings.
ZyndPay supports stablecoins rather than volatile-asset trading. The product purpose is payment, transfer and a dollar-denominated balance, not speculation or a promise of capital protection.
How the peg actually holds
USDT and USDC are issued by organizations separate from ZyndPay. Their issuers publish their own reserve, redemption and risk information, and market participants trade the tokens around the target value. Those issuer disclosures—not ZyndPay marketing—are the appropriate source for current reserve composition and direct-redemption eligibility.
A reserve-backed design still carries issuer, custody, liquidity, network and legal risk. A user’s ZyndPay balance is a custodial stablecoin balance, not a bank deposit opened in that user’s name and not an independently guaranteed claim of one dollar in every circumstance.
USDT and USDC
USDT (Tether) and USDC (USD Coin) are the two stablecoins ZyndPay works with. Both target a one-dollar value; they are issued by different companies and run on different networks.
ZyndPay supports them across multiple networks. Use only the asset-network pairs currently enabled and shown for the transaction. Network availability is operational configuration, not a permanent promise that every stablecoin works on every supported chain.
Why hold a stable-dollar balance
A dollar-referenced unit can simplify pricing, transfers and settlement when counterparties already account in dollars. It can also reduce exposure to movements in another currency, while introducing stablecoin-specific risks instead.
The balance can follow the spend, conversion or transfer paths enabled for the account. Availability, fees and exchange rates are shown in the relevant product flow; no universal rate, instant exit or guaranteed value is promised.

- No. Bitcoin’s price is volatile. A dollar-pegged stablecoin like USDT or USDC is designed to stay worth about one dollar, so it works as money rather than as a speculative asset.
- What is the difference between USDT and USDC?
- Both are dollar-pegged stablecoins issued by different companies and running on different networks. ZyndPay supports both; you can hold each and convert between them.
- Does ZyndPay support other cryptocurrencies?
- No. ZyndPay supports stablecoins only (USDT and USDC). It is not an exchange for volatile assets.
