# the pipes outlived the tickers

*pools, bridges, and carbon tokens were built for forests. the credits proved easier to issue than to sell. the pipes still run.*

[Regenerative finance](/guide/living-money?from=guide), ReFi for short, was a crypto movement that set out to move money toward forests, soils, and the people who look after them. Its builders shipped real infrastructure: a bridge that carried carbon credits onto a public chain, pools that made those credits tradeable as one asset, a treasury that bought and held them, and a registry that issued them without a broker in the middle. Then the credit market went quiet. On 27 July 2026, the best-known ReFi tokens traded between about $4 and about $1,213 in a day. Several teams closed. The contracts they built are still running.

That is the short answer to what happened to ReFi. The longer one takes a page, and it starts with what the pipes were for.

A forest keeps working whether or not anyone holds a credit or a certificate. [**Ensurance**](/?from=guide) gives that living system an account. DeFi is one set of tools that account can call. ReFi's builders pointed those same kinds of tools at a forest.

So this is a note about what shipped, in the order it shipped, before it is a note about what stalled. The hub for the series, [defi might just save refi](/guide/defi-might-just-save-refi?from=guide), makes the case in one page. This one is the record.

**the carbon tokens went quiet. the pipes under them did not.**

A bridge, a pool, a treasury, and a registry were built so a forest could be paid. The forest is still there, and so is most of the plumbing.

## the forest is why the pipes were built

Nobody built a carbon bridge because they wanted a token. They built it because a tonne of carbon held in a standing forest was certified, listed on a registry, and nearly impossible for an ordinary wallet to buy, hold, or retire. The registries were closed systems. The brokers took their cut. The forest, the thing doing the work, sat several intermediaries away from the money.

ReFi's bet was that a public chain could shorten that distance. Put the credit onchain and anyone can see it, hold it, and retire it in a transaction nobody can quietly undo. Put a treasury behind it and the price has a buyer. Put the registry itself onchain and issuance becomes legible to anyone who cares to look.

The practice underneath that bet is older than the tokens. Regenerative economics starts from the watershed and asks how money should circulate so the living system ends up better off, not worse. That practice has its own page, [living money](/guide/living-money?from=guide), and a later note in this series. Here it is enough to say that the pipes were built in service of it.

## what each project shipped

Specificity matters here, because "ReFi failed" is the kind of sentence that gets repeated without anyone checking what was actually built.

**Toucan** built the bridge. It took credits issued on a conventional registry, retired them there, and reissued them as tokens on a public chain, then pooled tokens that met a shared set of criteria so they could trade as a single asset. BCT, the Base Carbon Tonne, is one of those pool tokens. In 2025 Toucan handed the protocol to its community. As Crypto Altruists reports it, the team said carbon and crypto had met too early. BCT still sits in a pool on Polygon, though almost nothing trades.

**KlimaDAO** built a carbon treasury. It sold a token, used the proceeds to buy pooled carbon, and held that carbon in a treasury behind the token. The thesis was that a steady buyer would pull credits off the market and make pollution more expensive. Klima came back on Base in February 2026, smaller and with identity checks.

**Regen Network** built its own registry. Instead of bridging credits from someone else's ledger, it ran the registry and issued ecological credits onchain itself. It is still issuing. Its token, REGEN, trades thinly, but the registry is the product, and the registry runs.

Each of those is a piece of working infrastructure. A bridge. A pool. A treasury. A registry. The teams that built them are builders, and the record should say so before it says anything else.

## the credits proved easier to issue than to sell

Now the quiet part.

The State of ReFi Report 2025, published by CARBON Copy, put a number on it. About 12% of onchain ecological credits had been retired, against about 61% in the voluntary carbon market. Retirement is the moment a credit is used, the point where a buyer says this tonne offsets that emission and the credit leaves circulation. A credit that is issued and never retired is inventory. Onchain carbon turned out to be very good at creating inventory and much worse at clearing it.

The same report lists the projects that shut down along the way, Solid World, Coorest, and Thallo among them. They belong in the record as builders, not as failures.

The trading record shows the result. On 27 July 2026, CoinGecko's 24-hour figures for the main ReFi tokens looked like this.

| token | 24h volume | listed market cap |
|---|---|---|
| REGEN | about $348 | about $177k |
| BCT (Toucan pool) | about $4 | about $17k |
| KLIMA (old) | about $1,213 | $0 listed |
| K2 (newer Klima listing) | about $68 | about $765k |

The liveliest pool for the old KLIMA token that day was a KLIMA/WETH pair on Base, with about $1,323 in volume and about $12,521 in total value locked. Those are dated figures from one day. They are not a forecast, and they do not say what any of these projects is worth. They do say the tickers went quiet.

## this is not a eulogy

You may be reading this as an obituary. It is not, and the difference matters for what comes next in this series.

A ticker is a price for a token. A pipe is a contract that does something when called. When the carbon tokens stopped trading, the contracts did not uninstall themselves. And ReFi never owned the plumbing underneath. It built on DeFi's swaps, pools, and vaults, and those kept shipping after the carbon tickers stalled. They are called every day by people who have never heard the word ReFi.

That is the sense in which the pipes outlived the tickers. And it is the reason an account for a living system can use them without reviving a single carbon token.

On ensurance today, an account can call two kinds of pipe. It can swap one asset for another on Base, routed through 0x. And it can deposit USDC into, or withdraw it from, one of four allowlisted venues on Base. Those are the only venues; an address not on the list is refused. In every case the agent proposes a card and a person confirms it. Nothing moves until that confirmation. A vault share is not a certificate, and the protocol's own wallet cannot hold a yield position at all. The how-to for that is a later note.

The point here is narrower. The ReFi builders proved that a chain could be pointed at a forest. The market for the specific tokens they minted went quiet. The tools they used to do it are still on the shelf, and an account that answers to a watershed can pick them up.

## frequently asked

### what happened to refi?

ReFi, short for regenerative finance, was a crypto movement that built bridges, pools, treasuries, and registries so carbon and ecological credits could be issued, held, and retired on a public chain. The infrastructure worked. The market for the credits did not keep pace: the State of ReFi Report 2025 found about 12% of onchain credits retired against about 61% in the voluntary carbon market, and several projects closed. On 27 July 2026 the main ReFi tokens traded between about $4 and about $1,213 in a day. The contracts those teams deployed are still running.

### did toucan and klima shut down?

No. Toucan handed its protocol to its community in 2025, saying carbon and crypto met too early; BCT still sits in a pool on Polygon. KlimaDAO returned on Base in February 2026, smaller and with identity checks. Regen Network's registry is still issuing credits. The State of ReFi Report 2025 lists Solid World, Coorest, and Thallo among the projects that did close.

### are the pipes refi built on still usable?

Yes. Swaps, pools, and vaults are contracts, and they keep running whether or not a carbon token above them trades. On ensurance, an account can call a swap on Base through 0x, or a USDC deposit or withdraw on four allowlisted venues, and a person confirms every card before anything moves. Borrowing against a coin or a certificate is not available.
