Stablecoin

Stablecoin in cryptocurrency accounting

Stablecoin refers to a category of cryptocurrency tokens designed to maintain a stable value, typically pegged 1:1 to a fiat currency like the US dollar. Because they bridge the gap between volatile crypto assets and traditional currencies, stablecoins play a central role in DeFi, trading, and crypto accounting.

What is a stablecoin?

A stablecoin is a digital token that uses various mechanisms to keep its market price close to a target value. Most stablecoins are pegged to the US dollar, though some track the euro, gold, or other assets. They provide the programmability and speed of blockchain transactions without the price volatility that makes other cryptocurrencies challenging for everyday use.

There are three primary types of stablecoins:

Fiat-backed stablecoins

These tokens are backed by reserves of fiat currency or cash equivalents held by a centralized issuer. USDC (issued by Circle) and USDT (issued by Tether) are the most widely used examples. For every token in circulation, the issuer holds an equivalent amount in reserves. These are the simplest to understand and account for, though they require trust in the issuing entity.

Overcollateralized stablecoins

Protocols like MakerDAO issue DAI by requiring users to deposit crypto collateral worth more than the stablecoins they mint. If you deposit $150 worth of ETH, you might be allowed to mint $100 worth of DAI. This overcollateralization absorbs price volatility in the collateral asset. The accounting here is more involved because minting and redeeming DAI involves collateral positions with their own cost basis implications.

Algorithmic stablecoins

These tokens use smart contract algorithms to expand and contract supply based on demand, attempting to maintain the peg without traditional collateral. The collapse of TerraUSD (UST) in May 2022 demonstrated the risks of this approach and led to greater regulatory scrutiny of the entire stablecoin category.

Why stablecoins matter for crypto accounting

While stablecoins aim for price stability, they are not exempt from accounting requirements. The IRS and most tax authorities treat stablecoins as property, meaning every disposal is technically a taxable event. In practice, gains and losses on stablecoins are usually minimal, but they still need to be tracked.

Key accounting considerations include:

• Cost basis is rarely exactly $1.00: Exchange rates, fees, and minor depegging events mean your acquisition cost may differ slightly from the peg value. Over large volumes, these small differences can add up
• Swaps between stablecoins are taxable: Trading USDC for DAI is a disposal of one asset and acquisition of another, requiring cost basis calculations on both sides
• Interest and yield: Lending stablecoins through DeFi protocols or centralized platforms generates income that must be reported at fair market value when received
• Depegging events: If a stablecoin loses its peg (as happened with USDC briefly in March 2023), you may have unrealized losses or gains that become realized upon disposal

For businesses that use stablecoins for payroll, vendor payments, or treasury management, accurate stablecoin accounting is essential for financial statements and audit readiness.

How Tokenbooks handles stablecoins

Tokenbooks recognizes stablecoin transactions and applies transaction-time valuation, capturing cost basis rather than assuming a static $1.00 value. The platform supports tracking for stablecoin swaps, yield events, and depeg scenarios in supported flows.
