# Module overview

> The six custom Cosmos SDK modules that implement Autheo Chain's NFT license gating, dual-stream emissions, and EVM integration.

Autheo Chain adds six custom modules on top of Cosmos SDK and Ethermint. Each module has a distinct responsibility and interacts with the others through defined interfaces.

## x/license

**Store:** `license`

The central source of truth for all license state. Responsibilities include:

* Managing license records, policies, bindings, and lifecycle state transitions
* Providing an EVM hook for ERC-721 `Transfer` events that automatically mints license records when tokens are transferred to a recognized contract address
* Maintaining the owner index and binding registry

License records hold a unique auto-incremented ID (starting at 1), category (SOVEREIGN, PRIME, or CORE), owner Cosmos address, origin reference for deduplication, and status.

## x/licensedstaking

**Store:** Stateless

A wrapper around the standard staking module that enforces license preconditions before any validator or delegation operation. It contains:

* A `MsgServer` that intercepts `MsgCreateValidator`, `MsgDelegate`, `MsgUndelegate`, `MsgCancelUnbondingDelegation`, and related messages
* A `JailInterceptor` injected into the slashing module that transitions license status on jail and unjail events
* Post-call hooks that trigger `OnDelegationCreatedOrIncreased` to activate BOUND licenses after successful delegation

`MsgBeginRedelegate` is permanently rejected while the license system is active.

## x/emissions

**Store:** `emissions`

Manages all non-staking token minting via two per-block BeginBlocker routines:

1. **MintBlockRewards** — Mints community pool rewards (\~55.49 THEO per block by default)
2. **MintNFTBlockRewards** — Accrues per-block rewards to individual license KV balances for all eligible ACTIVE licenses

Both routines operate under a shared global emissions cap of 7 billion THEO. Staking inflation from `x/mint` is not counted against this cap.

## x/licensedistribution

**Store:** `licensedistribution`

Provides the user-facing interface for claiming accrued NFT emission rewards via `MsgClaimNFTRewards`.

```bash theme={null}
autheod tx licensedistribution claim-nft-rewards <license-id> \
  --from <owner-key> \
  --chain-id autheo_2127-1 \
  --keyring-backend file
```

## x/autheo

**Store:** `autheo`

Registers EVM log handlers and chain-specific EVM extensions. Acts as the integration layer between Ethermint and the custom Autheo modules.

## x/e2ee

**Store:** `e2ee`

Maintains an on-chain end-to-end encryption key registry. Allows participants to publish public encryption keys associated with their Cosmos addresses.

## License state summary

| Status    | Description                                                                                           |
| --------- | ----------------------------------------------------------------------------------------------------- |
| `ISSUED`  | Minted and owned; not yet bound to a validator. Can be bound or transferred.                          |
| `BOUND`   | Attached to a validator; no active delegation. Does not earn NFT emission rewards.                    |
| `ACTIVE`  | Attached to a validator with a live, positive-value delegation. Earns per-block NFT emission rewards. |
| `REVOKED` | Governance-suspended. Only `MsgReinstateLicense` can restore it to `ISSUED`.                          |
