• Supported assets: Most handle ETH/USDC; check exotics.
• Chains: Multi like deBridge for Solana+Base combos.
• Risks: Audits reduce exploits, but test small.
• Finality: Instant for natives, ~10 min for others.

Common question: Are bridges safe? Audited ones like Defiway and deBridge show clean records; always bookmark official sites and avoid phishing.

Step by Step Tips for Safe Ethereum to Base Bridging

1. Connect a compatible wallet like MetaMask-add Base network manually if missing: RPC https://mainnet.base.org, Chain ID 8453.
2. Choose bridge based on amount: Under $1K favors Across; larger picks deBridge for zero slippage.
3. Verify token support and swap if needed on Ethereum first to avoid failures.
4. Check live fees and gas-bridge during low Ethereum congestion for savings up to 50%.
5. Start with $10-50 test transfer to confirm receipt on Base explorer.
6. Monitor tx on both chains: Use Basescan for arrival, Etherscan for origin.
7. Enable 2FA on wallets and use hardware like Ledger for high values.
8. Withdraw to Base dApps promptly; leave minimal idle on bridges.
9. For returns to Ethereum, reverse via same bridge to leverage familiarity.
10. Track totals with tools like Zapper to optimize future routes.
