Fei USD FEI

What FEI actually is on-chain

Fei USD is an ERC-20 deployed on Ethereum, at contract address 0x956f47f50a910163d8bf957cf5846d573e7f87ca. That address, not the ticker FEI, is what uniquely identifies this asset: anyone can deploy a second token calling itself FEI, but the contract is unforgeable. Verify it against etherscan.io before sending funds or approving a spend.

Because it lives on Ethereum, FEI is held in any EVM-compatible wallet, transfers are paid for in ETH rather than in FEI itself, and secondary liquidity sits in Uniswap-style AMM pools. Two consequences follow for anyone setting alerts: you need ETH in the same wallet to move the token at all, and a quoted price taken from a pool is a pool price — it includes slippage that an order-book quote would not.

For FEI the project publishes an active account as @feiprotocol. That is a partial paper trail — enough to check claims against, not enough to audit. None of it is a quality judgement about the asset; it is simply what can be independently checked before the chart is worth looking at.

Where FEI sits in the market

At #1934, Fei USD is in the lower small-cap band. Books at this depth are thin enough that one sizeable market order can move the printed price by several percent and retrace within minutes, which is precisely why a single static price target makes a poor trigger — you want a condition that survives one wick. Availability is concentrated in a handful of venues and volume-based delisting is a live risk rather than a theoretical one.

We are not currently receiving a live FEI order book from any of the exchanges connected to this site, so no real-time quote is shown above. That is itself information: it usually means the pair is unlisted on the venues we track, or trading has been halted. FEI is a Ethereum asset, so whatever turnover exists is most likely in Uniswap-style AMM pools rather than on a centralised book, and every fill there costs ETH in gas on top of the pool's own fee.

FEI against its all-time high

Fei USD's record high is $5.55, set on 2024-03-16. That high sits in a range where whole-cent and whole-unit levels are genuinely traded, which makes them usable as alert thresholds if a quote returns. It was set 3 years ago, so it belongs to the current cycle but not to current conditions. We are not quoting a drawdown from it because no tracked venue is giving us a live FEI price — a stale or single-pool number would make that percentage look precise when it is not.

FEI across its historical range

The recorded range runs 35.7x, from $0.1554 to $5.55 — wide by the standards of traditional assets, moderate for this one's class.

The record low of $0.1554 was printed on 2023-12-30 — 3 years ago. We have no live quote to measure the current distance from it.

FEI supply and valuation data

Supply figures for FEI are self-reported at this rank rather than reconciled against the chain, so we publish the valuation we have and not a circulating-supply number we cannot check. What we do have is a fully diluted valuation of $3.8 million as of 2026-05-12. That is in the upper quartile of tracked assets by fully diluted value.

Because that valuation is a snapshot rather than a live figure, we deliberately do not back out a supply number from it — the price has moved since, and the division would produce a confident-looking token count that is simply wrong. Check the project's own explorer for the current supply before using any per-token valuation. The authoritative figure is the one etherscan.io reports for this contract.

What kind of asset FEI is

Fei USD is pegged to the US dollar, so the only price question that matters is whether the peg holds; trend and momentum readings on a dollar peg describe noise, not direction. Its peg is maintained algorithmically rather than by reserves. That is the most fragile of the stablecoin designs: the mechanism that defends the peg is itself reflexive, so it is strongest when it is least needed and weakest during the redemption pressure it exists to absorb. Depegs in this category tend to be step changes, not drifts. It is small for a stablecoin, and at this size the peg depends heavily on one or two liquidity pools; thin-book depegs here say more about liquidity than about solvency.

CoinGecko files FEI under 8 categories, including Stablecoins, Decentralized Finance (DeFi), USD Stablecoin, Ethereum Ecosystem, Coinbase Ventures Portfolio. CoinGecko also records deployments on Ethereum (3,072 tracked tokens), so its on-chain liquidity and its user base move with that network. Worth flagging from the metadata: FEI appears in the Andreessen Horowitz (a16z) portfolio.
