What is Stablecoin?

A stablecoin is a token designed to hold a fixed value, almost always one US dollar. The two largest, USDT and USDC, are backed by reserves of cash and short-term government debt held by the issuer, and are redeemable for dollars through the issuer for approved customers. Others are backed by crypto collateral locked in smart contracts, or hold their peg through algorithms, and those designs have failed more often than the reserve-backed ones. Holding a stablecoin on an exchange adds the exchange as a counterparty on top of the issuer, which is one more reason the total should show where each dollar actually sits.

Stablecoins are the settlement layer of crypto. Most trading pairs are quoted in them, most exchange balances are held in them between trades, and most on-chain lending is denominated in them. On Tron in particular, USDT is the reason most wallets exist. A stablecoin position is therefore rarely a bet on anything; it is the cash side of a portfolio, and the question is only whether the peg holds. The market shows which designs it trusts: the reserve-backed pair dominates by a wide margin.

The risks are specific. Reserve-backed coins carry issuer and banking risk, visible on the rare occasions a coin trades below a dollar during a bank event. Crypto-collateralized coins carry liquidation risk in a crash. A stablecoin on a particular chain also carries that chain’s bridge risk if it arrived there by bridge rather than by native issuance.

TrueHold treats USDT and USDC as dollars for valuation, the same convention the exchanges it reads prices from use, and counts every stablecoin balance across chains and exchanges into the total. The same token on several chains is merged into one holding and the merge is disclosed.

For tracking, the useful detail is where each dollar sits. A stablecoin on an exchange, on Ethereum, on Tron and on a layer 2 is four different exposures with four different risks, even though the total reads as one number.
