Adds liquidity to an Aerodrome pool on Base. Supports both stable (sAMM) and volatile (vAMM) pools. Handles token approvals automatically. IMPORTANT: Requires ERC20 tokens, not native ETH. Use wrap-eth first to convert ETH to WETH (0x4200000000000000000000000000000000000006). Use aerodrome-get-lp-positions to check existing positions first. Ideal for: yield farming, liquidity provision, DeFi automation.
