The Dollar On The Internet: How Stablecoins Work

Stablecoins give software a tokenized unit of account that can move on a supported blockchain. They can shorten some settlement paths and make payment logic programmable, but they do not remove issuer, custody, network, market, sanctions, or redemption risk.

The correct comparison is transaction-specific. A stablecoin transfer may be cheaper or faster than a bank or card route, or it may add exchange, network, custody, and compliance costs that erase the advantage.

What a Stablecoin Is

A stablecoin is a digital token designed to track a reference asset, often the US dollar. The issuer may commit to primary-market redemption at a stated value, while the token's secondary-market price can trade above or below that value.

USDC is intended to maintain a value of $1. Circle's direct redemption commitment is subject to its terms, eligibility, applicable law, account status, and possible fees. A holder who cannot open an eligible Circle Mint account may need an exchange or other intermediary to convert USDC to fiat.

This design reduces price volatility relative to unpegged assets. It does not eliminate depegging, issuer, reserve, custody, smart-contract, blockchain, or liquidity risk.

How They Stay Stable

Reserve structure and redemption terms determine how a fiat-backed stablecoin seeks to hold its peg. Circle reports USDC reserves that include cash, short-dated US Treasuries, overnight Treasury repurchase agreements, and the Circle Reserve Fund. It publishes weekly reserve composition and monthly third-party assurance that reserve value exceeded USDC in circulation at the reporting date.

Paxos describes PYUSD as fully backed and publishes monthly reserve reports and independent attestation reports. Direct mint and redemption access depends on the issuer's account and eligibility requirements.

Algorithmic stablecoins use a different mechanism and can fail without a sufficient redemption asset. Reserve-backed designs reduce that specific risk but still depend on the issuer, custodian, reserve assets, operational controls, and redemption access.

Where to Get Them

Stablecoins can be acquired through an eligible issuer account, exchange, wallet, payment provider, or another counterparty. Access, supported networks, fees, spreads, limits, identity checks, custody, and consumer protections vary by provider and jurisdiction.

Businesses evaluating direct issuer access should read the current terms rather than assume every holder can redeem with the issuer. They should also verify the contract address and network before accepting or sending a token with a familiar ticker.

Where Stablecoins Can Fit

Stablecoins are used for treasury movement, cross-border settlement, merchant payments, payouts, tokenized markets, and machine-readable purchases. Actual speed and cost depend on the blockchain, wallet, provider, compliance review, liquidity, and off-ramp.

On-chain transfers may be technically irreversible after confirmation, while a provider can still offer refunds, escrow, account controls, or dispute processes around the transfer. Businesses should design the commercial remedy instead of assuming the rail supplies one.

Programmability can bind a payment to contract logic, schedules, or application state. Code can also fail, be exploited, or encode the wrong conditions, so operational and legal review remain part of the payment design.

What the Skeptic Gets Right

A reserve attestation is useful evidence at a reporting date. It is not an audit of every operational control, a guarantee of future redemption, or protection against wallet, network, smart-contract, custody, market, or legal risk.

Evaluate the issuer, reserve composition, assurance report, redemption eligibility, supported networks, custody model, sanctions controls, fees, liquidity, and recovery plan. The ticker alone is not the product.
