Flatcoins: the inflation-proof cryptocurrency the crypto world has been waiting for
Stablecoins protect you from crypto volatility — but not from inflation. Every year, your $1 USDT quietly buys less. Flatcoins are designed to fix exactly that: a new class of crypto assets that preserve your real purchasing power over time, not just your nominal dollar value.
What is a flatcoin?
A flatcoin is a type of cryptocurrency specifically designed to preserve purchasing power over time by tracking real-world inflation metrics — rather than maintaining a fixed peg to a fiat currency like the US dollar.
In simple terms: while $1 USDT will always be worth $1 in nominal value, $1 worth of a flatcoin should still buy you the same amount of goods and services in 5 years as it does today. It adjusts upward as inflation rises.
The term was first coined in 2021 by former Coinbase CTO Balaji Srinivasan and Sam Kazemian, founder of the Frax stablecoin, during a discussion about building a stablecoin that truly preserves the standard of living of its holders.
Why stablecoins are not enough?
Stablecoins like USDT and USDC solve the problem of cryptocurrency volatility. But they introduce a different, slower problem: inflation erosion. They are pegged to fiat currencies, and fiat currencies themselves lose value over time.
At 3% annual inflation — historically modest — $1,000 in USDT loses about 26% of its real value in 10 years. For people in countries like Argentina, Turkey, or Venezuela where inflation can exceed 100%, stablecoins provide very little real protection.
How flatcoins work
Flatcoins use a combination of on-chain oracles, algorithmic supply controls, and collateral mechanisms to maintain their inflation-adjusted peg. Here is the core process:
1
Inflation data feed (oracle)
A decentralized oracle (such as Truflation) tracks real-world price data — consumer basket, CPI, or purchasing power parity — and feeds it on-chain daily. Truflation monitors over 10 million data points to produce its inflation index.
2
Target price adjustment
The protocol updates the flatcoin's target peg value each day based on the new inflation reading. If annual inflation is 4%, the target price of the flatcoin increases by approximately 4%/365 each day.
3
Algorithmic supply control
When the market price diverges from the peg, the protocol incentivizes users to mint or burn tokens. If price is above peg, the collateral ratio drops, encouraging minting. If below, users are incentivized to burn tokens or add collateral.
4
Overcollateralization
Most flatcoins are backed by more collateral than their face value (similar to DAI), using assets like ETH, BTC, or real-world assets (RWAs). This protects the peg even during market stress and prevents the collapse seen with algorithmic stablecoins like TerraUST in 2022.

Real-world flatcoin projects
Several projects are already building or have launched flatcoins. Here are the most notable ones:
Coinbase & industry backing
"What would it look like to make a better form of money enabled by crypto? It would probably be totally decentralized and track consumer prices to preserve purchasing power, or something close to it."
— Brian Armstrong, CEO of Coinbase
Coinbase CEO Brian Armstrong has publicly named flatcoins as one of his top 10 most exciting crypto ideas — and identified them as a key area of interest for Coinbase's future. Ethereum co-founder Vitalik Buterin has also highlighted inflation-resistant stablecoins as one of the most underexplored opportunities in crypto.
Use cases for flatcoins
Long-term savings in DeFi
Rather than holding USDT and watching inflation silently erode value, DeFi users can hold flatcoins to ensure their savings maintain real purchasing power year over year.
Remittances for emerging markets
Global remittances exceeded $900 billion in 2024. For families receiving money from abroad — especially in high-inflation countries — flatcoins ensure the value sent doesn't shrink before it is spent. Unlike dollar-pegged stablecoins, flatcoins can reflect local purchasing power dynamics.
DeFi protocol base unit
Flatcoins can serve as the unit of account for lending protocols, insurance markets, DAOs, and prediction markets — ensuring that all values expressed within these systems remain economically meaningful over time, not just nominally stable.
Hyperinflation hedge
In countries like Venezuela (270% inflation in 2025) or Zimbabwe, even holding USD stablecoins doesn't truly protect purchasing power in local terms. Flatcoins tied to broader cost-of-living indices offer a more robust hedge.
Risks and challenges
Frequently asked questions
Is a flatcoin the same as a stablecoin?
No. A stablecoin maintains a fixed peg to a fiat currency (e.g. $1 USD). A flatcoin pegs to an inflation index, so its nominal value rises over time while its real purchasing power stays constant. Every flatcoin is a type of stablecoin, but not every stablecoin is a flatcoin.
Can a flatcoin lose value?
In deflationary environments (when prices fall), a flatcoin's nominal value would also decrease. However, your purchasing power remains the same — you can still buy the same basket of goods. In persistent inflation (the historical norm), flatcoins are designed to appreciate in nominal terms.
What inflation index does a flatcoin use?
Projects like Nuon use Truflation — a decentralized on-chain oracle that tracks over 10 million price points daily. Others use the US Consumer Price Index (CPI), purchasing power parity (PPP), or a custom basket of commodities and services.
Are flatcoins safe after TerraUST collapsed?
TerraUST was undercollateralized and relied entirely on algorithmic incentives. Most flatcoin designs — such as Nuon — are overcollateralized, meaning each token is backed by more collateral than its face value, making a similar death spiral structurally much harder to trigger.
Where can I buy or mint a flatcoin?
Nuon is available on decentralized exchanges on Arbitrum. SPOT and other projects are in various stages of development and testnet. As adoption grows, flatcoins are expected to list on major centralized exchanges too.
