The transition between ERC20 tokens and native mainnet tokens is a critical process in blockchain evolution, especially for projects upgrading from Ethereum-based tokens to their own independent blockchains. This guide dives deep into the mechanics, use cases, and technical workflows behind token migration—using real-world insights and practical examples to clarify how users and developers can navigate this process securely and efficiently.
Whether you're managing digital assets or exploring blockchain interoperability, understanding the bridge between ERC20 and mainnet tokens is essential.
Understanding ERC20 and Mainnet Tokens
ERC20 is a technical standard used for smart contracts on the Ethereum blockchain to implement tokens. These tokens are widely supported across wallets, exchanges, and decentralized applications (dApps), making them ideal for initial coin offerings (ICOs) and early-stage projects.
However, as blockchain projects mature, many choose to launch their own independent networks—referred to as "mainnets"—to achieve greater scalability, lower transaction fees, and full control over consensus mechanisms. When this happens, the project must migrate its ERC20 token holders to the new native token on its mainnet.
This migration involves two core processes:
- Depositing ERC20 tokens to receive equivalent mainnet tokens.
- Withdrawing mainnet tokens to receive ERC20 tokens.

Case Study: YOYOW’s ERC20 to Mainnet Migration
YOYOW serves as an excellent example of a successful token transition from ERC20 to a custom-built mainnet. The process relies on a gateway system that acts as a trust intermediary between the Ethereum network and YOYOW’s native blockchain.
How ERC20 Tokens Are Converted to Mainnet Tokens
When users want to move their YOYOW ERC20 tokens to the mainnet, they follow these steps:
- Generate a Gateway Address: The YOYOW gateway assigns each user a unique Ethereum address linked to their mainnet account.
- Send ERC20 Tokens: Users transfer their YOYOW ERC20 tokens to this designated gateway address.
- Monitor Blockchain Activity: The gateway continuously monitors the Ethereum blockchain for incoming transactions to its controlled addresses.
- Credit Mainnet Account: Once the transfer is confirmed, the gateway credits the user's YOYOW mainnet account with an equivalent amount of native tokens.
The original ERC20 tokens sent to the gateway remain locked in a wallet controlled solely by the YOYOW team—ensuring no double-spending occurs. Since only the project holds the private key, these funds cannot be accessed by anyone else.
For example, one known gateway address is 0xEcA9408E85170c9511c8884Ad035868cD6310d86. Transactions to this address can be verified on Etherscan, confirming transparency in the deposit process.
Monitoring Gateway Activity
The gateway operates through a centralized account on the YOYOW mainnet—identified as yoyow_gateway1 (Account #43752382). This account functions under a multi-signature ownership model, enhancing security by requiring multiple approvals for any transaction.
Public records show that this account primarily issues outgoing transfers—indicating active withdrawals by users moving tokens back to Ethereum. While this may raise questions about selling pressure, it also reflects healthy liquidity and user engagement.
YOYOW’s ERC20 contract is publicly available at: 0xcbeAEc699431857FDB4d37aDDBBdc20E132D4903
You can review its full code and transaction history on Etherscan for audit purposes.
Withdrawing Mainnet Tokens Back to ERC20
The reverse process—moving native YOYOW tokens back to the ERC20 version—is equally important for users who wish to trade on Ethereum-based platforms.
Here’s how it works:
- Initiate Withdrawal: Users send their mainnet YOYOW tokens to the gateway account.
- Gateway Verification: The system confirms receipt and validates the destination Ethereum address.
- Execute ERC20 Transfer: The gateway triggers a smart contract call on Ethereum, sending the equivalent amount of YOYOW ERC20 tokens to the user’s specified wallet.
- Transaction Fee Handling: In some cases, network fees are deducted in the native token (e.g., 10 YOYOW per transaction), ensuring smooth cross-chain operations.
This bidirectional bridge ensures flexibility without compromising asset integrity.
Frequently Asked Questions (FAQ)
Q: Is my token safe during the conversion process?
A: Yes, as long as the gateway is operated by a trusted entity with transparent addresses. Always verify official gateway addresses through official channels before sending funds.
Q: Can I lose my tokens if I send them to the wrong address?
A: Absolutely. Sending tokens to an incorrect or non-gateway Ethereum address may result in permanent loss. Double-check all addresses carefully.
Q: Why do some gateways only show outgoing transactions?
A: Gateways often batch incoming deposits off-chain and only record outgoing distributions on-chain. This improves efficiency and reduces clutter in public ledgers.
Q: Do I need to pay gas fees in ETH when depositing ERC20 tokens?
A: Yes. Any transaction on the Ethereum network requires ETH to cover gas fees, regardless of the token being transferred.
Q: What happens if the project shuts down its gateway?
A: If support ends, future conversions may no longer be possible. It’s advisable to complete migrations while official infrastructure remains active.
Q: Are there alternatives to centralized gateways?
A: Emerging solutions include decentralized bridges and atomic swaps, though most current implementations still rely on trusted intermediaries for simplicity and reliability.

Best Practices for Safe Token Migration
- Verify Official Sources: Always obtain gateway addresses from official websites or verified community announcements.
- Test with Small Amounts: Before transferring large holdings, perform a test transaction with a minimal amount.
- Keep Records: Save transaction hashes (txIDs) for both sides of the conversion in case support is needed.
- Monitor Confirmation Times: Ethereum confirmations can vary based on network congestion; allow sufficient time before assuming failure.
- Use Reputable Wallets: Ensure your wallet supports both ERC20 tokens and the target mainnet for seamless management.

The Future of Cross-Chain Transfers
As blockchain ecosystems grow more interconnected, automated bridges and interoperability protocols like Polkadot, Cosmos IBC, and LayerZero are paving the way for trustless token migrations. However, for many existing projects like YOYOW, centralized gateways remain the most practical short-term solution.
Understanding how these systems work empowers users to make informed decisions about their digital assets—balancing convenience, security, and long-term value preservation.
