Stablecoin

Stablecoin is a token whose market price is engineered to stay close to a reference value. The reference is most often the US dollar, sometimes the euro, gold, or a basket of assets. On TON, stablecoins act as the network’s unit of account: traders quote prices in them, perpetuals settle in them, and ordinary users hold them to ride out Toncoin volatility without leaving the chain.

Why they matter

Native tokens like Toncoin fluctuate. A merchant who accepts TON for a 10-dollar product might collect 7 dollars worth tomorrow. A stablecoin removes that risk by holding price near one unit of the reference asset, typically with sub-percent deviation under normal conditions.

Typical TON use cases:

• Peer-to-peer transfers without exchange-rate exposure.
• A “safe” sleeve of a wallet during market drawdowns.
• Collateral and borrow asset on lending protocols and DEX.
• Payments inside Telegram bots, mini apps, and merchant flows.

Types of stablecoins

The industry divides them by the peg mechanism:

• Fiat-collateralized. The issuer holds bank deposits and short-term government bonds equal to the supply of issued tokens. Examples are USDT (Tether) and USDC (Circle). This is the dominant model on TON, where Tether has issued a native USDT jetton since 2024.
• Crypto-collateralized. Backing comes from on-chain crypto assets with overcollateralization (for example, 1.5 units of crypto locked per 1 unit of stablecoin). DAI on Ethereum is the canonical example. TON has not yet produced a major equivalent.
• Algorithmic. Price is defended by mint-and-burn mechanics rather than a one-to-one reserve. The category was severely damaged by the UST collapse in 2022, and users now treat purely algorithmic designs with significant caution.

USDT on TON

USDT is the dominant stablecoin in the TON ecosystem. Tether issued a native jetton version that lives on standard jetton rails: a jetton master holds the total supply, each holder has their own jetton wallet, transfers travel through TON Connect, wallets, and mini apps. USDT on TON is attractive for low-fee transfers and fast finality — a meaningful advantage over USDT on Tron or Ethereum for retail-sized payments.

Risks

• Depeg. The link to the reference asset can break. The best-known example is USDC in March 2023, when part of the reserve was stranded in Silicon Valley Bank and the price briefly traded below one dollar. Smaller wobbles also occur in USDT during periods of panic.
• Regulatory risk. The issuer is centralized. Addresses can be frozen on request from law enforcement; Tether has historically frozen wallets across multiple jurisdictions.
• Reserve quality. For fiat-collateralized stablecoins, the composition and verifiability of the reserve is the central question. Tether publishes attestations, but a full independent audit remains a separate topic of debate.
• Token contract risk. Technical risk is minor for major issuers, but verifying the jetton master address before accepting payments is still essential — copy-cat jettons with similar tickers do appear on TON.

A stablecoin is the foundation of any DeFi stack; on TON, that role belongs to the USDT jetton, and most user-facing flows route through it in one form or another.
