pancakeswap-v2-plugin

Overview

Swap tokens and manage liquidity on PancakeSwap V2's constant-product AMM (0.25% fee) across BSC, Base, and Arbitrum — LP tokens are standard ERC-20 and composable with other DeFi protocols.

Prerequisites

• onchainos agentic wallet connected
• Some tokens on a supported chain — BSC (default), Base, or Arbitrum

How it Works

• Check your wallet: Get a personalised next step based on your balances on the active chain. pancakeswap-v2-plugin quickstart
  • If status: no_funds or needs_gas — fund your wallet with the native gas token first
  • If status: needs_funds — you have gas but no tokens; transfer tokens to your wallet or swap the native token
  • If status: ready — proceed below
• Swap:
  • 2.1 Get a quote: Check the expected output before committing — no gas. pancakeswap-v2-plugin quote --token-in USDT --token-out CAKE --amount-in <amount>
  • 2.2 Execute the swap: Send input token and receive output — ERC-20 approval fires automatically if needed. pancakeswap-v2-plugin swap --token-in USDT --token-out CAKE --amount-in <amount> --confirm
• Provide liquidity:
  • 3.1 Look up a pair: Find the LP contract address for a token pair. pancakeswap-v2-plugin get-pair --token-a CAKE --token-b BNB
  • 3.2 Check reserves: See the current token balances and implied price in a pair. pancakeswap-v2-plugin get-reserves --token-a CAKE --token-b BNB
  • 3.3 Add liquidity: Deposit both tokens of the pair to receive LP tokens. pancakeswap-v2-plugin add-liquidity --token-a CAKE --token-b BNB --amount-a <amount-a> --amount-b <amount-b> --confirm
  • 3.4 Check LP balance: View your LP token holdings for a pair. pancakeswap-v2-plugin lp-balance --token-a CAKE --token-b BNB
  • 3.5 Remove liquidity: Burn LP tokens to withdraw your proportional share of the pool. pancakeswap-v2-plugin remove-liquidity --token-a CAKE --token-b BNB --liquidity <amount> --confirm
