Step-by-Step Guide

1. Connect Your Wallet
   Click "Connect Wallet" to link your preferred wallet (e.g., MetaMask).

2. Select Networks and Asset

   • From: Ethereum Mainnet
   • To: Optimism
   • Choose the token (e.g., USDT, USDC, ETH).

   👉 Switch your wallet to Ethereum Mainnet before proceeding.

3. Enter Transfer Amount
   Specify the amount in the "Send" field. The estimated received amount will display automatically.
4. Review and Confirm
   Verify transaction details (fees, gas estimates). Click "Transfer" and approve the prompts.

5. Await Completion
   Most transfers finish within minutes. Track progress via the "Transfer History" tab.

   Note: Heavy network traffic may delay transfers (up to 20 minutes).

Ethereum Mainnet Overview

Ethereum is a decentralized platform powering smart contracts and dApps. Key features:

• Native Currency: Ether (ETH)
• Use Cases: Payments, DeFi, NFTs
• Layer-2 Support: Optimism, Arbitrum

ETH Asset Details

Description: ETH is required for all Ethereum transactions, including gas fees and smart contract interactions.

Optimism Explained

Optimism is a Layer-2 scaling solution for Ethereum. Benefits:

• Lower Fees: Reduced gas costs vs. Ethereum Mainnet
• Faster Transactions: Off-chain computation
• Compatibility: Supports all Ethereum dApps

👉 Bridge assets to Optimism with cBridge for 50% lower gas fees than native bridges.

ETH on Optimism

Identical in function to Ethereum Mainnet ETH, but optimized for Layer-2 efficiency.

Understanding Crypto Bridges

What Is a Bridge?

A blockchain bridge enables asset/date transfers between chains. Examples:

• USDT Ethereum → Optimism
• NFT Cross-Chain Transfers

Bridge Types

1. Liquidity-Based
   Uses pools on both chains (e.g., cBridge).
2. Canonical-Based
   Locks assets on the source chain, mints equivalents on the destination.

Trust Models:

• Trusted: Centralized control
• Trustless: Smart contract-driven (e.g., cBridge)

Benefits of Using Bridges

• Cost Efficiency: Avoid high fees on congested chains.
• Access Opportunities: Explore high-yield DeFi on other chains.
• Ecosystem Diversity: Trade, lend, or stake across multiple blockchains.

Example Use Case

Move USDC from Ethereum to Optimism to capitalize on higher lending interest rates.

FAQ

How long do transfers take?

Typically under 5 minutes, but may extend to 20 minutes during peak traffic.

Is bridging safe?

Trustless bridges like cBridge use audited smart contracts for maximum security.

Which tokens can I bridge?

Major tokens (ETH, USDC, USDT) are supported, plus select NFTs.

What are the fees?

Costs vary by token and network conditions. cBridge offers competitive rates.

Conclusion

Cross-chain bridges unlock interoperability in Web3. For secure, low-cost transfers between Ethereum and Optimism, leverage trusted solutions like cBridge.
