approve_token_spending

Authorize a DeFi protocol or exchange to spend your ERC20 tokens by specifying the token address, spender address, and amount. Essential for enabling token interactions in decentralized applications.

Approve another address (like a DeFi protocol or exchange) to spend your ERC20 tokens. This is often required before interacting with DeFi protocols.

Input Schema

Name	Required	Description
`amount`	Yes	The amount of tokens to approve in token units, not wei (e.g., '1000' to approve spending 1000 tokens). Use a very large number for unlimited approval.
`network`	No	Network name (e.g., 'ethereum', 'optimism', 'arbitrum', 'base', 'polygon') or chain ID. Defaults to Ethereum mainnet.
`privateKey`	Yes	Private key of the token owner account in hex format (with or without 0x prefix). SECURITY: This is used only for transaction signing and is not stored.
`spenderAddress`	Yes	The contract address being approved to spend your tokens (e.g., a DEX or lending protocol)
`tokenAddress`	Yes	The contract address of the ERC20 token to approve for spending (e.g., '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48' for USDC on Ethereum)
