# based on nature, never backed by it

*in rwa lending the asset is posted so it can be sold if the loan fails. a forest sold to cover a loan keeps only the protection its next owner allows*

RWA collateral is a tokenized real world asset that a borrower posts to a lender in order to borrow against it. The lender reads the token's price from a price feed, lends less than that price, and sets a liquidation threshold. If the price falls far enough, the position is sold to repay the loan. The public example on Base: on 25 September 2026, Aave opened an Equities Hub that accepts seven Coinbase stock tokens as collateral, with USDC to borrow against them.

For a Treasury bill or a share of stock, that is a good design. The sale is the lender's safety.

Now put a forest in the same slot. A forest, a wetland, or a watershed keeps working whether or not anyone tokenizes it, and nearly everything on the RWA list leans on a living system. [**Ensurance**](/?from=guide) brings onchain finance and that living foundation together in one design, so money can fund the living system. It is based on that system, never backed by it. The difference between those two prepositions is where the forest ends up when a price falls.

**in rwa lending the sale is the safety. for a forest, a forced sale is the risk.**

Collateral is posted so it can be sold if the loan fails. A living system that can be sold to cover a loan is only as safe as the next buyer's plans. Here the money circulates, and no coin or certificate puts the forest on the table.

:::

A few terms, once. A **coin** (general ensurance) is a token that trades on Base. A **certificate** (specific ensurance) is minted 1:1 to an **agent**, an onchain account that holds the mandate for a place, people, or purpose.

## how rwa collateral works

Every RWA loan has the same three parts.

1. **A token posted to a lender.** The borrower locks a claim on something offchain: a fund share, a bond, a stock. The lender holds it for as long as the loan is open.
2. **A price feed.** An oracle reports what the token is worth, on a schedule the lender trusts. On Aave's Equities Hub that feed is Chainlink. The loan is sized against that number, always below it.
3. **A liquidation threshold.** If the collateral's price falls far enough against the debt, anyone can repay part of the loan and take the collateral at a discount. The sale is meant to make the lender whole.

It all rests on one assumption: the collateral can be sold quickly, and it stays the same asset after the sale. For paper assets these rails are real progress, and their builders deserve the credit. A desk that can pledge a [tokenized fund share](/guide/collateral-that-still-needs-a-basin?from=guide) as margin without redeeming it first has a better tool than it had.

## isn't collateral the whole point of rwa?

You might be thinking it is. Much of the case for tokenizing anything is that a token can be posted and liquidated outside bank hours. An asset that cannot be posted looks unfinished.

For a Treasury bill, that is right. When a tokenized bill is liquidated, a liquidator buys it at a discount and the lender is repaid. The bill still matures on the same date. The government still pays the same interest. Liquidation is the feature, because the asset does not care who holds it.

A stock is nearly the same. The company keeps operating whoever holds the share. The collateral survives being sold.

## why the sale is the end for a forest

A forest is different at the liquidation step.

Ask what a lender's price feed for a forest would read. Not the water it filters, the floods it slows, or the habitat it holds. Those reach everyone downstream and send no one a bill, so no market quotes them every minute. A feed would read what a buyer would pay for the land today, which mostly means what can be cut, built, or drained. The dead parts are priced. The living system is not.

Then ask what a forced sale does. A liquidation does not ask what the buyer plans for the land. It asks who will pay now. The forest may stay standing after that sale. Nothing in the sale makes it. Whatever protection depended on the old holder's intentions ends at the closing.

| | posted (rwa collateral) | based on, not backed by |
|---|---|---|
| what the token is | a claim the lender can sell | a coin or a certificate that funds the place |
| what the price feed reads | the token's market price | no lender feed; a valuation of the place is not a price to lend against |
| what happens in a downturn | the collateral is sold to repay the loan | instrument prices can fall; no coin or certificate can force a sale of the place |
| what keeps the asset whole | nothing needs to; a bill survives any holder | recorded restrictions, set by property law and not by the token |

## based on, not backed by

[Living money](/guide/living-money?from=guide) puts the whole idea in one preposition. **Backed by** is a collateral relationship: the holder has a claim on the thing named, and in a crisis that thing is what gets called. **Based on** means the living system is the ground the money stands on, and no coin or certificate pledges it.

The rule here is plain. Circulation funds the base. No coin and no certificate is a claim that can be redeemed into, foreclosed on, or liquidated as the forest, the wetland, or the watershed. Coins trade, and their prices move. Certificates fund a named agent. When a market falls, what falls is the price of an instrument. The living system was never on the table, so there is nothing of it to sell through the token.

A certificate is also not a deed. It conveys no title, no mortgage, no possession, and no right to redeem into land. *Nearly every real world asset leans on a living system.* This design keeps the living one out of the liquidation.

## the same land, held two ways

There is a place in this catalog where land does secure money, and it does not contradict any of this. [The land is the collateral](/guide/the-land-is-the-collateral?from=guide) describes acquisition capital secured by the title of the place it helped buy, until premiums from the parties who depend on that place repay it. That is a cost-side real-estate arrangement, documented the ordinary way, with its own rights and its own risks. The land is pledged there, and if the premiums fail the holder keeps the title and can sell it. That arrangement does not by itself protect the place.

Keep the two apart. In that arrangement, titled real property secures the acquisition capital, as a credit committee would expect. On the onchain side, nothing is pledged: no coin or certificate reaches the land, and no lender can call it through them.

And neither side is where permanence comes from. Permanence does not depend on who holds the title on a given day. It comes from restrictions that bind whoever holds it next: a conservation easement, a deed restriction, recorded against the land. A perpetual easement held by a land trust or agency binds a later buyer. It holds against a later lender only if it is recorded ahead of the loan or the lender subordinates. Property law does the protecting, and it needs counsel to get right.

## can you borrow against a coin or a certificate?

Borrowing against a coin or a certificate is not available. No lender lists our coins or certificates as collateral, and no oracle prices a certificate for a lender.

If that ever changed, the order would be a deep pool and a funded exchange floor first, and the forest would stay off the table.

A stock token on a lending desk arrives with a custodian, a price feed, and a market. [The token is the holding](/guide/the-token-is-the-holding?from=guide) walks through what Superform's stock vaults on Base did with that collateral, and why a certificate on a forest is not part of it. Coinbase's stock tokens are offered under Regulation S, not to U.S. persons, and nothing here suggests posting one.

## frequently asked

### what is rwa collateral?

RWA collateral is a tokenized real world asset, such as a fund share, a bond, or a stock token, posted to a lender to borrow against. The lender prices it with an oracle, lends below that price, and liquidates the position if the price falls past a set threshold.

### can you use a forest as collateral in defi?

Not in this design. Collateral exists to be sold when a loan goes bad, and a forced sale carries no protection with it unless a restriction was recorded first. Money here is based on the living system, never backed by it: no coin or certificate can be redeemed into or liquidated as the forest. Acquisition finance secured by a title is a separate real-estate arrangement.

### can i borrow against an ensurance certificate?

No. Borrowing against an ensurance coin or certificate is not available. No lender lists them as collateral, and no oracle prices a certificate for a lender. A certificate is not a deed either: it conveys no title to land.

## next

The next note takes the word **underlying** apart, because in this design it carries two meanings that have to stay separate: the living system, and the titled parcel that property law can protect.
