Mainnet Swap

A mainnet swap is the process of migrating a project's token from a temporary or placeholder blockchain to its own newly launched mainnet. During development, projects typically issue ERC-20 tokens on Ethereum or other established networks to facilitate fundraising and early community building. Once their proprietary blockchain reaches production readiness, the project conducts a token swap where users exchange their old tokens for equivalent native tokens on the new mainnet. This migration often involves a one-time conversion event with a specified deadline, and holders must actively participate or risk losing access to their tokens. Example: The Cosmos Hub conducted a mainnet swap in March 2019, converting ATOM ERC-20 tokens held on Ethereum into native ATOM tokens on the newly launched Cosmos mainnet, marking the transition from testnet to full operational status. Why it matters for tokenomics: Mainnet swaps establish the canonical token for a blockchain ecosystem and consolidate liquidity on the native network. This migration event is critical for bootstrapping on-chain activity, determining final token distributions, and signaling technical readiness to markets and users.
