Overview

Echo supports Ethereum and EVM-compatible chains (Polygon, Arbitrum, Base, Optimism). Accept ETH or any ERC-20 token for payments, tips, or premium content. Wallet ownership can be verified via signed message (no transaction required) which enables token-gated experiences like NFT-holder-only chats or DAO-member premium content.
