What is a Stablecoin

Stablecoins are a sort of cryptocurrency in which the digital asset’s value is expected to be tied to another asset, such as fiat money, exchange-traded commodities, or another cryptocurrency. In principle, 1:1 backing by a reference asset might cause a stablecoin’s value to mirror the value of the peg, but issuers have not been proven to keep significant reserves to sustain a stable value in practice.

Stablecoins have a variety of uses, such as payments, and are more likely to keep their value than volatile cryptocurrencies.

Some examples of well-known Stablecoin projects include USD Coin and BUSD which was started by Binance.

Fiat-backed approaches (backed by a traditional currency such as USD, Euro, etc)


Reserve-backed stablecoins are digital assets that are supported by other assets and are unlikely to fall below the underlying physical asset’s value owing to arbitrage. The value of fiat-backed stablecoins is determined by the value of the underlying currency, which is held by a third-party-regulated financial firm. Cryptocurrencies backed by fiat money are the most widespread and were the market’s first stablecoins.

Their value is pegged to one or more currencies (most commonly the US dollar, euro, and Swiss franc) in a fixed ratio; the value connection is realized off-chain, through banks or other types of regulated financial institutions that serve as depositaries of the currency used to back the stablecoin; and the amount of the currency used to back the stablecoin should reflect the stablecoin’s circulating supply.

National Australia Bank stated in January 2023 that it would launch the AUDN, an Australian Dollar fiat-backed stablecoin, for facilitating cross-border financial transactions and trading carbon credits.

Stablecoins backed by commodities such as Gold or Silver

The following are the primary characteristics of commodity-backed stablecoins:

  • Their value is linked to one or more commodities and redeemable for those commodities (more or less) on demand;
  • There is an implied or explicit commitment to redeem, made by unregulated people, agorist enterprises, or even regulated financial institutions;
  • The amount of commodity used to back the stablecoin should correspond to the stablecoin’s circulating supply.

Holders of commodity-backed stablecoins can redeem their stablecoins at the conversion rate to acquire possession of the underlying assets, subject to the conditions in existence at the time of redemption regarding timing and amount. The cost of holding and protecting the commodity underpinning is the cost of sustaining the stablecoin’s stability.

Cryptocurrency based approaches

Crypto backed stablecoins

Cryptocurrency-backed stablecoins are issued with cryptocurrencies as collateral, which is conceptually similar to fiat-backed stablecoins. The main difference between the two designs is that the cryptocurrency or crypto asset used to support this sort of stablecoin is done on the blockchain, using smart contracts in a more decentralized method.

These characteristics include the stablecoin’s value being collateralized by another cryptocurrency or a cryptocurrency portfolio, the peg being executed on-chain via smart contracts, the supply of stablecoins being regulated on-chain, and price stability achieved through the introduction of supplementary instruments and incentives.

The technical implementation of this sort of stablecoin is more complex and diversified than that of fiat-collateralized stablecoins, which increases the danger of exploits due to faults in smart contract code. The change in the value of the collateral and the dependency on extra instruments are potentially problematic aspects of this sort of stablecoin. Havven, DAI, and other live stablecoin projects are examples of this category.

Basis, a stablecoin project that had attracted over $100 million in venture capital funding, shut down in December 2018, citing regulatory issues in the United States. Diem (previously Libra) was acquired by Silvergate Capital after being abandoned by Facebook/Meta.

Risks & advantages

Advantages & Risks to Stablecoins

Potential advantages

Potential for greater stability and the best of both worlds (traditional & digital currencies)

Stablecoins, which can interact with blockchain-based apps, can be more stable than Cryptocurrencies and can bring some of the benefits of fiat currencies.


They are less expensive to use and provide larger returns than standard savings accounts. Stablecoin holders can take out loans backed by their coins and insure their crypto assets.

Cross border payments

Stablecoins make cross-border payments faster and cheaper because they are generally accepted and liquid.

Ability to be backed by commodities

Commodity-backed stablecoins make precious metals and other commodities more convenient to transport, divide, and lend for interest.

Potential risks

Lack of regulations

According to Nellie Liang, Under Secretary of the Treasury for Domestic Finance, who testified before the Senate Banking Committee, the rapid expansion of the stablecoin market capitalization and its potential for financial services innovation necessitates immediate congressional regulation.

Lack of transparency

Tether is the world’s largest market capitalization stablecoin at the moment. It has been accused of failing to deliver audits for reserves used to collateralize the amount of USDT stablecoin generated. Tether has now given assurance reports on USDT support, but considerable speculation remains.


Many projects can develop a product and refer to it as a stablecoin. As a result, despite their name, many stablecoins have historically lacked stability due to the digital assets’ capacity to be built to a variety of standards. Stablecoins like TerraUSD, USDD, DEI, and others all fell to zero in 2022.
