Linea supports all EVM-compatible wallets, including MetaMask, WalletConnect wallets, and 1inch Wallet. Manual setup:
Mainnet:
Network name: Linea Mainnet
RPC: https://rpc.linea.build
Chain ID: 59144
Symbol: ETH
Explorer: https://lineascan.buildFees on Linea are low, generally only a few cents paid in ETH. Transactions confirm quickly on L2, usually within a few seconds. Full settlement on Ethereum L1 depends on zk-proof generation and submission, which adds a delay for absolute finality but does not affect day-to-day swaps.
Yes. Linea batches transactions and proves them on Ethereum via zk proofs. This means L2 confirmations are fast for UX, but L1 finality depends on proof submission cycles. Developers and users should be aware of this gap between fast L2 confirmation and delayed L1 settlement.
Stable pairs usually work with 0.1–0.3% slippage. For liquid volatile pairs, 0.5–1% is common. Illiquid or highly volatile pairs may need 1–2% or more. Adjust slippage based on pool size and recent volatility to avoid failures.
Avoid granting unlimited token allowances. Approve only the amount needed per swap, and use Permit2 or permit flows when available. Regularly review and revoke unused approvals via the block explorer or trusted revoke tools.
Linea’s protocol itself is permissionless, with no chain-level restrictions. Compliance checks or geo-blocking may apply at the application, wallet, or bridge level, depending on the service provider.
