Key features
NFT license-gated staking — Validators require a Sovereign NFT license. Delegators require a Prime or Core license bound to their target validator. Licenses originate as ERC-721 tokens on Arbitrum and are bridged into the chain automatically via an EVM hook. Three license tiers — Each tier grants different staking rights and earns a fixed annual NFT emission reward.| Tier | Purpose | Annual THEO emission |
|---|---|---|
| Sovereign | Create and operate a validator | ~187,969 |
| Prime | External delegation (higher tier) | ~18,797 |
| Core | External delegation (standard tier) | ~1,880 |
x/mint via x/distribution automatically. NFT emission rewards accrue per block in x/emissions and require a manual claim via x/licensedistribution.
Full EVM compatibility — Autheo Chain runs a full Ethermint EVM with Ethereum JSON-RPC on ports 8545 (HTTP) and 8546 (WebSocket). MetaMask, ethers.js, Hardhat, and Foundry all work with Mainnet Chain ID 2127.
IBC support — Native interoperability via ibc-go v10.1.1.
