Layer 2
Layer 2 networks process activity outside a base blockchain and use that base chain for part of their settlement or security. Rollups batch transactions and submit data or proofs to a Layer 1.

What are Layer 2 crypto projects?
Browse the buying guidesThey aim to increase capacity and reduce the cost per transaction. A sidechain with its own independent security model is not automatically a Layer 2 simply because it connects to Ethereum.
How it works
Optimistic and validity-proof systems use different methods to establish that transactions are correct. Their withdrawal paths, data availability, sequencers and upgrade controls also differ. The network’s token may govern decisions or incentives rather than pay gas, so buying that token is not the same as buying the asset needed to use the chain. Ecosystem growth should be considered alongside unlocks and the token’s actual function. Moving funds through a bridge adds dependencies beyond a normal wallet transfer.
A little groundwork goes a long way
Before your next purchase or transfer, understand who controls access, where your crypto is going and what the trade will actually cost.
Protect access to your crypto
An exchange account and a self-custody wallet need different safeguards. Protect exchange logins with a unique password and strong two-factor authentication. For self-custody, your recovery backup is what lets you restore access.
Keep recovery words offline and private. A support agent or website asking for them is a reason to stop.
See a recovery example
Your phone breaks. An exchange may help you recover your account after identity checks. A self-custody wallet cannot reset your recovery phrase. Check your wallet’s official backup instructions before relying on it.
Choose the right transfer network
The asset, token version and network must be supported at the destination. A familiar ticker or a matching address format is not enough. Read the receiving platform’s deposit instructions before selecting a withdrawal network.
Check the address, any required memo or tag, fees and minimums. Consider a small test transfer first.
See a network example
Your destination accepts USDC on Ethereum. Selecting a cheaper network at the sending exchange does not make it an Ethereum transfer. Use a network both ends support; an ordinary withdrawal does not bridge tokens.
Understand the price you pay
Trading fees are only part of the cost. The spread, available liquidity and withdrawal charges also matter. A market order prioritizes execution; a limit order controls the price but may remain unfilled or fill only partly.
Check the order preview and the amount you will receive, then compare the full cost of your intended purchase and withdrawal.
Work through a cost example
Hypothetical example: a $200 trade with a 0.1% trading fee costs $0.20 in trading fees. A separate $5 withdrawal fee brings those charges to $5.20. Spread or slippage may add more; these are not quoted exchange rates.
