Many newcomers are exploring SN, a blockchain-based game, hoping to earn income or simply have fun. However, the complexity of on-chain networks often leads to confusion. Players frequently struggle to understand what they are doing and why certain operations are necessary.
This guide addresses common questions from community discussions, such as why specific steps are required, why tokens might not arrive as expected, and the differences between various wallet types and exchange platforms.
Core Concepts: Exchanges and Web3 Wallets
What Is an Exchange?
An exchange functions similarly to a traditional stock exchange, like the NYSE or NASDAQ. It facilitates the trading of digital assets, such as buying Bitcoin (BTC) or Ethereum (ETH). For user convenience, exchanges provide built-in wallet addresses to send and receive tokens. However, these integrated wallets have limitations compared to dedicated Web3 wallets.
What Is a Web3 Wallet?
A Web3 wallet acts like a personal digital wallet, storing any tokens sent to it. Wallets can be chain-specific (e.g., BTC wallet, ETH wallet) or multi-chain, supporting multiple networks. For example, some wallets allow interactions across various blockchains without switching platforms.
Wallets are essential for on-chain interactions, such as using a bridge to transfer USDC tokens from the Arbitrum (ARB) network to the Immutable (IMX) network. Without a Web3 wallet, these operations are impossible.
Why Do Many Addresses Look Identical?
Most wallets use Ethereum Virtual Machine (EVM) compatibility, meaning they share the same address format across multiple networks. However, identical addresses do not imply the same network.
Consider this scenario:
Alice holds 1000 USDC on the Ethereum network and wants to send it to Bob’s Arbitrum address. She uses Bob’s Ethereum-style address, and the transaction succeeds. But the tokens remain on Ethereum—not Arbitrum.
Why?
Arbitrum is a sidechain of Ethereum. While addresses are similar, the networks are distinct. To correctly transfer tokens:
- Use a cross-chain bridge supporting Ethereum-to-Arbitrum transfers.
- After bridging, send USDC to Bob’s address.
Always verify the recipient’s network to avoid errors.
Why Can’t I Interact With My Tokens?
The likely culprit is insufficient gas fees.
Every blockchain transaction requires gas, paid in the network’s native token:
- Ethereum: ETH
- BNB Smart Chain: BNB
- Immutable: IMX
- Arbitrum: ETH (but cheaper than Ethereum mainnet)
Without gas, you cannot approve transactions, transfer tokens, or interact with dApps.
When sending tokens from an exchange to a wallet, ensure you:
- Only use networks mentioned in reliable guides.
- Have enough native tokens for gas.
Otherwise, assets may become stuck and unusable.
Mainnets and Sidechains Explained
What Is a Mainnet?
A mainnet is a primary blockchain network. For Ethereum-based projects, Ethereum is the mainnet. It processes transactions and hosts smart contracts but suffers from high gas fees and slower speeds during congestion.
What Are Sidechains?
Sidechains are independent networks connected to a mainnet, like Arbitrum or Immutable zkEVM for Ethereum. They offer:
- Faster transactions
- Lower fees
- EVM compatibility (same address format)
Sidechains reduce the mainnet’s load while maintaining security through cryptographic proofs.
Practical Tips for On-Chain Operations
- Double-Check Addresses and Networks: Always confirm the recipient’s address and network before sending tokens.
- Acquire Native Tokens for Gas: Before interacting, ensure your wallet holds the network’s native token for gas fees.
- Use Trusted Bridges: For cross-chain transfers, rely on well-audited bridges to avoid risks.
- Start Small: Test with small amounts before large transactions to minimize potential losses.

Frequently Asked Questions
What is the difference between an exchange and a Web3 wallet?
Exchanges are trading platforms with integrated wallets for convenience. Web3 wallets are self-custodial tools giving full control over assets and enabling direct on-chain interactions.
Why did my tokens not arrive after sending?
This often occurs when tokens are sent to the correct address but the wrong network. Verify the network and consider using a blockchain explorer to track the transaction.
Can I use the same wallet for different networks?
Yes, if it’s a multi-chain wallet. However, you must add each network manually and manage gas tokens separately for each chain.
What happens if I send tokens to the wrong network?
Recovery is difficult and sometimes impossible. Always confirm the network before transacting.
How do I get gas tokens for a new network?
Purchase them on a exchange and withdraw to your wallet, or use a gas faucet if available. Some bridges also offer partial gas coverage.
Are sidechains as secure as mainnets?
Security varies. While sidechains inherit some security from mainnets, research each network’s consensus mechanism and audit history.
Conclusion
Understanding on-chain networks is crucial for navigating Web3 environments safely. By mastering the roles of exchanges, wallets, mainnets, and sidechains, you can avoid common pitfalls. Always prioritize security: verify addresses, networks, and gas requirements. Your assets are your responsibility—stay vigilant.
