Stablecoins Compared: Issuer, Redemption, and Depeg Risk

By Alex O · Updated 2026-07-28

A stablecoin replaces market-price volatility with issuer, reserve, redemption, smart-contract, and network risk. USDT, USDC, and USDP are issuer-backed liabilities with different legal and reserve arrangements; USDJ is crypto-collateralized; USDN is a historical depeg failure. A one-dollar quote is not the same as a direct, unconditional right to redeem one token for one dollar.

Issuer-backed stablecoins: USDT, USDC, and USDP

Stablecoins are tokens designed to track a reference asset, usually the US dollar. They can provide a useful settlement unit for trading, DeFi, and payments, but they do not remove volatility under stress and generally do not carry deposit-insurance protection.

Tether (USDT), launched in 2014, is designed to track the US dollar across several networks. Tether publishes reserve information and attestations, but users should distinguish an attestation from a full financial-statement audit and read the terms defining who may redeem directly. In 2021 Tether settled with the New York Attorney General over historical reserve representations. Availability in the EU depends on service providers' MiCA obligations and should be checked with the regulated venue rather than inferred from global circulation.

USD Coin (USDC) was launched in 2018 and is issued by Circle. Circle publishes reserve composition and third-party assurance reports for cash, short-dated US Treasuries, and related reserve assets. Native USDC exists on multiple networks; bridged representations introduce a bridge or third-party issuer and must not be assumed equivalent to native issuance.

Paxos Standard (now Pax Dollar, USDP, formerly PAX) is a regulated stablecoin issued by Paxos Trust Company, which is chartered as a trust company by the New York State Department of Financial Services. USDP reserves are held in segregated accounts at US banks and backed entirely by cash and cash equivalents. Paxos previously issued the Binance USD (BUSD) stablecoin on behalf of Binance, but regulatory actions by the New York Department of Financial Services in 2023 led Paxos to stop minting new BUSD tokens, and the supply has since wound down substantially.

USDN failure and USDJ collateral risk

USDN (Neutrino USD) was an algorithmic stablecoin created on the Waves blockchain. Unlike fiat-collateralized stablecoins, USDN used a crypto-collateralized mechanism where WAVES tokens served as backing. In 2022, USDN lost its dollar peg and traded significantly below $1 for extended periods, highlighting the risks inherent in algorithmic and crypto-collateralized stablecoin designs. The collapse of Terra's UST stablecoin in May 2022 further demonstrated that reflexive stabilization mechanisms can fail when confidence and collateral value fall together.

WAVES warning: withdrawal problems — an opinion and experience report

In our assessment — published as an opinion in the exercise of free speech, based on our own experience and publicly observable events — the WAVES platform behaves like a black hole for assets: funds we converted into WAVES-ecosystem derivatives such as USDN could not be withdrawn afterwards. The project has also repeatedly changed its web domains over the years, which we regard as a serious red flag for anything holding customer assets.

In our opinion, WAVES is a scam coin — or rather a scam platform. Treat any conversion into WAVES or its derivative tokens as potentially irreversible. This is not investment advice; do your own research and verify actual redemption and withdrawal rights before committing funds.

USDJ is a stablecoin on the TRON blockchain, created through the JUST protocol. Similar to MakerDAO's DAI on Ethereum, USDJ is generated by depositing TRX as collateral into smart contracts called Collateralized Debt Positions (CDPs). The system maintains the peg through over-collateralization and automated liquidation mechanisms. USDJ occupies a niche position within the TRON ecosystem but has not achieved the scale or adoption of the major stablecoins.

Payments and DeFi introduce new dependencies

The primary use case for stablecoins is facilitating cryptocurrency trading. Traders use stablecoins to move quickly between volatile assets and a stable reference value without converting back to fiat currency, which can be slow and involve banking intermediaries. On most cryptocurrency exchanges, stablecoin trading pairs (such as BTC/USDT or ETH/USDC) are the most liquid markets. Stablecoins also enable 24/7 settlement, unlike traditional banking systems that operate on business hours and weekday schedules.

In decentralized finance (DeFi), stablecoins serve as the primary unit of account for lending, borrowing, and yield farming protocols. Users can deposit stablecoins into lending protocols to earn interest, borrow against crypto collateral in stablecoin terms, and provide liquidity to decentralized exchanges. The stability of stablecoins makes DeFi protocols more predictable and useful for participants who want exposure to yield opportunities without the additional risk of underlying asset volatility.

Cross-border settlement can run continuously, but the blockchain transfer is only one leg. The sender still needs compliant acquisition, the recipient needs a usable wallet or off-ramp, and both sides bear network, spread, custody, screening, tax, and possible freeze risk. Compare the complete delivered cost and settlement time with a bank or payment provider; a low gas fee does not make the full payment rail cheap.

Regulation and a redemption-first checklist

Stablecoin regulation now has enacted frameworks on both sides of the Atlantic. In the United States, the GENIUS Act became law in July 2025; in the EU, MiCA's rules distinguish e-money tokens from asset-referenced tokens and impose authorization, reserve, disclosure, and operational requirements. The exact treatment still depends on issuer, token design, jurisdiction, and implementation timeline, so a compliance label is not a substitute for reading redemption terms and identifying the regulated legal entity.

Issuer-backed tokens depend on reserves, banks, governance, and redemption access. Crypto-collateralized tokens add oracle and liquidation risk; reflexive designs can enter a confidence spiral. Run a depeg exercise: decide which price source triggers action, who may trade, which venue and network remain usable, and whether a direct redemption account exists. A policy that merely says “sell at $0.98” fails if every venue is congested.

Before accepting a stablecoin, identify the legal issuer, native network and contract, direct redemption eligibility, reserve and assurance reports, freeze or upgrade powers, banking cutoffs, bridge exposure, and treatment in issuer insolvency. Test mint or redemption through the actual business path. For operational cash, set concentration limits and a contingency rail rather than relying on one token or chain.
