Autheo Chain is an EVM-compatible Layer 1 blockchain derived from Cronos and built on Cosmos SDK v0.53.0. It extends standard staking with a custom NFT license gating system that governs who can operate validators and delegate stake.

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. Dual reward streams — Staking rewards flow from 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.
