Coins are nature-linked ERC-20 currencies where market activity indirectly funds ecosystems. They represent general ensurance—broad participation in natural capital protection.
why
Direct funding of natural assets requires commitment and expertise. But many participants want exposure to natural capital without managing specific assets.
Coins provide:
- Liquid, tradeable participation
- Indirect funding through market activity
- Diversified exposure across ecosystems
- Familiar currency mechanics
They're the entry point—money that expresses care for nature. In the two-sided capital structure, coins serve both members and participants: flow investors can hold them as a form of participation, and trading activity generates proceeds that fund protection. Coins are the only indirect funding instrument — certificates (both policies and lines) are direct.
what
coin characteristics
| Property | Description |
|---|---|
| Standard | ERC-20 |
| Scope | Protocol-wide or theme-specific |
| Funding model | Indirect via trading activity |
| Yield | Via proceeds distribution |
| Liquidity | Tradeable on DEXs |
coin types
Coins serve different purposes in the protocol:
| Type | Description | Example |
|---|---|---|
| Protocol coin | Primary ensurance currency | $ENSURE |
| Ecosystem coins | Tied to ecosystem types | $WETLANDS, $FORESTS |
| Service coins | Tied to ecosystem services | $CLIMATE, $WATER |
| Regional coins | Tied to geographic regions | $AMAZON, $CORAL |
All coins share the same mechanics. They differ in what they represent and where proceeds flow.

Protection & Stewardship Funded
Coins don't directly purchase land or conservation easements. They create market activity that generates proceeds, which then flow to natural asset protection.
how
holding coins
Coins can be held in:
- Your owner account (🟢 external wallet)
- Your operator account (🔵 server wallet)
- An agent TBA (tokenbound account)
When agents hold coins, they participate in the market on your behalf.
trading coins
Coins trade on decentralized exchanges via 0x aggregation:
| Action | What Happens |
|---|---|
| Buy | Swap stablecoins/ETH for ensurance coins |
| Sell | Swap ensurance coins for other assets |
| Swap | Exchange between ensurance coin types |
All swaps route through optimal liquidity paths. Proceeds are collected automatically.
proceeds from coins
Coin holders receive proceeds through:
- Protocol rewards — Distributed from protocol activity
- Pool fees — When coins are in liquidity pools
- Agent distributions — When held in agent TBAs
See proceeds for detailed mechanics.
Distribution eligibility: Only members (agent account holders) who hold coins in connected wallets receive protocol distributions. Participants can hold and trade coins but do not receive distributions.

coin vs certificate
| Aspect | Coins | Certificates |
|---|---|---|
| Standard | ERC-20 | ERC-1155 |
| Scope | Protocol-wide | Asset-specific |
| Funding | Indirect (trading) | Direct (purchase) |
| Liquidity | High (DEX tradeable) | Lower (marketplace) |
| Yield source | Protocol rewards | Premium stream + protocol distributions |
| Distribution eligibility | Members with agent accounts | Members with agent accounts |
Coins are for liquid participation. Certificates are for direct commitment.
