# The Sarcophagus

The Sarcophagus is a permissionless claim mechanism intended for the 5% protocol share from fee-only or ungauged pools.

## The Sarcophagus: Deflationary Module

A **5% protocol share** from fee-only or ungauged pools can flow into the Sarcophagus. Callers exchange an exact, owner-configured amount of RAM for selected accumulated fee tokens.

**Fee accumulation creates a potential RAM-for-fees claim; it does not guarantee that a claim or burn will occur.**

---

## How It Works

| Step | Description |
| --- | --- |
| **Fee Collection** | The 5% protocol share from configured fee-only or ungauged pools flows to the Sarcophagus |
| **Accumulation** | Owner-allowlisted fee tokens accumulate until selected in a claim |
| **Claim Mechanism** | Any caller can transfer the exact `exchangeAmountThreshold` of RAM and claim selected allowlisted token balances |
| **Chain Handling** | Ethereum burns the received RAM; other chains send it to the configured dead address in the current implementation |

Calling the claim function is permissionless, but its threshold, token allowlist, maximum token count, and rescue function are owner-controlled.

## Fee Distribution

| Pool State | Liquidity Providers | xRAM Voters | Protocol / Sarcophagus |
| --- | --- | --- | --- |
| **Gauged** | 0% | 100% | 0% |
| **Fee-only / Ungauged** | 95% | 0% | 5% |

> **Maker Rebates**
>
> Maker rebates are treasury-funded and additive, up to 1%. They are not deducted from the 95% LP / 5% protocol swap-fee split.

## Claim Mechanics

Any address can call `bury` when the selected fee-token balances are worth exchanging for the configured RAM threshold. Searchers may monitor this opportunity, but execution and profitability are not guaranteed.

| Action | Result |
| --- | --- |
| Transfer exact RAM threshold | `exchangeAmountThreshold` is set by the owner and must be greater than zero |
| Select fee tokens | Claim the full Sarcophagus balance of each selected, owner-allowlisted token, subject to `maxTokenClaim` |
| Protect execution | Supply the current nonce and minimum amounts for the selected tokens |

> **Permissionless Execution, Managed Parameters**
>
> Anyone can submit a valid claim. The owner can change the RAM threshold, maximum number of claimed assets, and token allowlist, and can rescue tokens from the contract.

## Deflationary Impact

The Sarcophagus can remove RAM from circulation when fee balances make a claim economical:

- More trading volume = more fees
- More fees = larger Sarcophagus balance
- A larger balance may create more incentive to exchange the configured RAM threshold
- A completed Ethereum claim burns RAM; the current non-Ethereum path sends RAM to a dead address

Fee accrual alone does not burn RAM, and reduced supply does not guarantee an increase in token price.

---

## Chain-Specific RAM Handling

Sarcophagus behavior depends on the chain where a contract is actually deployed:

| Chain | Effect |
| --- | --- |
| **Ethereum** | Calls the RAM token's burn function, reducing token total supply |
| **Non-Ethereum Chains** | Sends RAM to the `0x…dEaD` address in the current implementation, reducing circulating supply but not ERC-20 `totalSupply` |
| **Undeployed Chains** | No effect until a Sarcophagus contract and fee route are deployed and published |

Any later canonical reconciliation or Ethereum burn is a separate process and should not be inferred from the non-Ethereum transfer alone.

## Maker Rebate Program

Ramses may fund a **Maker Rebate Program** from treasury resources. This program is separate from the pool's swap-fee split:

| Feature | Details |
| --- | --- |
| **Allocation** | Up to 1%, funded by the treasury and additive to pool fees |
| **Recipients** | High-performing liquidity providers |
| **Goal** | Reward efficient market making |

Eligibility, measurement periods, and payment amounts depend on the published rebate program. A rebate is not guaranteed by the Sarcophagus contract.

### Benefits for Market Makers

- Potential additional treasury-funded rebates
- No need to participate in governance
- Eligibility can be based on published performance criteria
- Compatible with automated strategies

## Combined Fee Flows

The two default swap-fee states and the separate rebate program are:

| Mechanism | Flow |
| --- | --- |
| **Fee-only / Ungauged** | 95% to LPs and 5% to the protocol / Sarcophagus |
| **Gauged** | 100% to xRAM voters and 0% to LPs by default |
| **Maker Rebates** | Up to 1% treasury-funded and additive; not part of either swap-fee percentage |

These flows describe token routing. They do not guarantee returns or token-price appreciation.
