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.

​
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.
