Base Carbon Tonne BCT

What BCT actually is on-chain

Base Carbon Tonne is an ERC-20 deployed on Polygon, at contract address 0x2f800db0fdb5223b3c3f354886d907a671414a7f. That address, not the ticker BCT, is what uniquely identifies this asset: anyone can deploy a second token calling itself BCT, but the contract is unforgeable. Verify it against polygonscan.com before sending funds or approving a spend.

Because it lives on Polygon, BCT is held in any EVM-compatible wallet, transfers are paid for in POL rather than in BCT itself, and secondary liquidity sits in QuickSwap and Uniswap pools. Two consequences follow for anyone setting alerts: you need POL 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 BCT the project publishes a whitepaper. 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 BCT sits in the market

Base Carbon Tonne ranks #3610, in the upper long tail, past the point where most data providers stop publishing supply figures, 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 BCT 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. BCT is a Polygon asset, so whatever turnover exists is most likely in QuickSwap and Uniswap pools rather than on a centralised book, and every fill there costs POL in gas on top of the pool's own fee.

BCT against its all-time high

Base Carbon Tonne's record high is $8.60, set on 2021-11-29. 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 5 years ago. A peak that old describes a supply structure and a holder base that have almost certainly turned over since. We are not quoting a drawdown from it because no tracked venue is giving us a live BCT price — a stale or single-pool number would make that percentage look precise when it is not.

BCT across its historical range

BCT has traded across a 401x range, between $0.0215 and $8.60. Any volatility figure quoted for this asset depends heavily on which part of that range it is measured over.

The record low of $0.0215 was printed on 2026-03-11 — about a year ago. We have no live quote to measure the current distance from it.

BCT supply and valuation data

Supply figures for BCT 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 $570 thousand as of 2026-05-12. That sits around the middle of the distribution — roughly half the assets tracked here carry a smaller fully diluted value.

Since the figure is a snapshot rather than a live number, we do not reverse it into a supply count: the price has moved since it was taken, and that division would produce a confident but incorrect token count. For any per-token valuation, check the current supply on the project's own explorer first. The authoritative figure is the one polygonscan.com reports for this contract.

What kind of asset BCT is

Base Carbon Tonne is a base-layer network, so BCT is simultaneously the chain's security budget and its unit of account rather than a claim on a business. 1,487 tokens tracked on this site are tagged to its ecosystem. That is the fourth-largest such set here, behind Solana's 3,129. The honest way to value a chain at that scale is as infrastructure rent: demand for BCT is derived from how much economic activity chooses to settle there, and because large smart-contract platforms compete for the same developers, these assets trade on ecosystem-share narratives far more than on incremental releases. It is secured by proof of stake, so a portion of the supply is bonded to validators at any moment and the float genuinely available to trade is smaller than the circulating figure implies; unstaking queues, not order books, set how fast that can change.

CoinGecko files BCT under 3 categories, including Polygon Ecosystem, Regenerative Finance (ReFi), Base Ecosystem. CoinGecko also records deployments on Polygon (531 tracked tokens), so its on-chain liquidity and its user base move with that network.
