eth_getBalance

Returns the balance of a given address on Linea.

Why Linea? Build on Consensys-backed zkEVM L2 with $1B+ TVL and 807% growth in 2025 with 15-30x lower fees than Ethereum mainnet, 6,200 TPS throughput, SWIFT integration with 12+ institutions, and $725M Consensys backing.

Use Cases

The eth_getBalance method is essential for:

• Wallet applications - Display user balances
• Transaction validation - Check if account has sufficient funds
• DeFi applications - Monitor collateral and liquidity for enterprise DeFi (Aave, Renzo), institutional cross-border payments via SWIFT pilots, and zkEVM-native applications
• Account monitoring - Track balance changes over time

Parameters

Parameter	Type	Required	Description
address	DATA	Yes	20-byte address to check balance for
blockParameter	QUANTITY|TAG	Yes	Block number in hex, or "latest", "earliest", "pending", "safe", "finalized"

Request
