# CheomaYield

**CheomaYield** is a fixed-APY yield protocol. Users deposit stablecoins into tokenized vaults and earn a fixed, advertised annual yield — backed primarily by Gulf (GCC) sovereign and corporate sukuk bonds, with a small market-neutral satellite sleeve.

## What it does

1. **Deposit** a stablecoin (USDC / USDG) into a vault.
2. **Earn** a fixed APY (accrues deterministically on-chain).
3. **Redeem** after the lock window for principal + accrued yield.

Each vault is a self-contained smart contract with an immutable `apyBps` rate, a principal cap, and a custody split between a config-only admin key and a cold treasury key.

## Two vault families

| Family                                      | Purpose                                   | Deposit asset          | Yield                    |
| ------------------------------------------- | ----------------------------------------- | ---------------------- | ------------------------ |
| **Pre-Deposit vaults** (`CheomaPreDeposit`) | Fixed-APY campaign vaults                 | USDC (Base)            | 52% APR (Wave 1)         |
| **Partner vaults** (`PartnerPreDeposit`)    | Bond-gated vaults for partner communities | USDG (Robinhood Chain) | 56.3% APR (GIWA Markets) |

> The \~13% sustainable rate is the target for the full mainnet product (Wave 2). The 52% / 56.3% figures are time- and cap-bounded promotional rates on small caps.

## Who this is for

Integration partners (DEXs, aggregators, wallets, money markets, cross-chain execution layers) who want to surface CheomaYield's high fixed APRs to their users — either as a deposit destination or as a high-yield lend source.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cheomayield.gitbook.io/cheomayield-docs/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
