Extra Finance EXTRA

What EXTRA actually is on-chain

Extra Finance is an ERC-20 deployed on Optimism, at contract address 0x2dad3a13ef0c6366220f989157009e501e7938f8. That address, not the ticker EXTRA, is what uniquely identifies this asset: anyone can deploy a second token calling itself EXTRA, but the contract is unforgeable. Verify it against optimistic.etherscan.io before sending funds or approving a spend.

Because it lives on Optimism, EXTRA is held in any EVM-compatible wallet, transfers are paid for in ETH rather than in EXTRA itself, and secondary liquidity sits in Velodrome and Uniswap 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 EXTRA the project publishes a public source repository and an active account as @ExtraFi_io. 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 EXTRA sits in the market

Extra Finance ranks #2174, in the top of the long tail, just below the band most screeners still cover, far outside the set of assets that carry continuous market-maker coverage. At this end of the table the first question is data integrity rather than valuation: a quote can originate from a single pool or a single venue, reported volume is difficult to verify independently, and the distance between the last print and a genuinely executable price can be wide. Treat any indicator computed on this series as provisional.

We are not currently receiving a live EXTRA 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. EXTRA is a Optimism asset, so whatever turnover exists is most likely in Velodrome and Uniswap pools rather than on a centralised book, and every fill there costs ETH in gas on top of the pool's own fee.

EXTRA against its all-time high

Extra Finance's record high is $0.2879, set on 2024-03-27. 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 EXTRA price — a stale or single-pool number would make that percentage look precise when it is not.

EXTRA across its historical range

The recorded range runs 50.7x, from $0.00567283 to $0.2879 — wide by the standards of traditional assets, moderate for this one's class.

The record low of $0.00567283 was printed on 2026-05-08 — within the last six months. We have no live quote to measure the current distance from it.

EXTRA supply and valuation data

Supply figures for EXTRA 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 $5.2 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 optimistic.etherscan.io reports for this contract.

What kind of asset EXTRA is

Extra Finance is a DeFi protocol token, which ties it to total value locked and to the interest-rate environment on-chain. These assets carry a beta to the market plus a second exposure that is easy to miss: protocol risk. A contract exploit or an oracle failure repriced instantly and independently of any market move, and that tail is a real component of holding the token.

CoinGecko files EXTRA under 4 categories, including Decentralized Finance (DeFi), Optimism Ecosystem, Base Ecosystem, Base Native. CoinGecko also records deployments on Optimism (125 tracked tokens), Base (1,487 tracked tokens), so on-chain liquidity is split across several networks and the cheapest venue depends on which deployment you are trading.
