Limit Order Creator

WHAT IT DOES

Limit Order Creator is a DeFi tool that simulates the creation of limit orders for tokens. Select the order type (Buy or Sell), enter the token address, set the price in USD, specify the order size, and set an expiration in blocks — the tool generates a simulated limit order with an order ID, calculates the total value, and displays the order status. This is essential for traders learning how limit orders work, developers testing order creation interfaces, or anyone understanding the mechanics of placing limit orders on DEXes or order book exchanges.

HOW TO USE

Connect your wallet using the BGWallet bridge (MetaMask or any Web3 wallet). Select the order type: "Buy" or "Sell." Enter the token address (the token you want to buy or sell). Enter the token price in USD — this is your limit price. Enter the order size in tokens. Set the expiration in blocks — the order will remain active for this many blocks. Click "Create limit order" to generate the simulated order. The tool displays the order type (with a Buy/Sell badge), token address (shortened), price, size, total value, expiration, order status, and a unique order ID. The order status is "Open (buy order)" or "Open (sell order)" — indicating the order is pending execution. This is useful for understanding the parameters of a limit order and how they affect the order.

TECHNICAL MECHANISM

The tool simulates a limit order creation by generating a deterministic order ID (a random hex string) and calculating the total value (price × size). The order type determines the direction of the trade — Buy orders are marked with a green badge, Sell orders with a red badge. The status is set to "Open" with the order type. The expiration is displayed in blocks. The tool does not actually interact with any DEX or order book contract — it generates a simulated order for demonstration purposes. In a real implementation, the tool would call a DEX router or order book contract to place the order, handle token approvals, and manage order lifecycle. All operations are performed client-side — no data is stored or transmitted. The tool is read-only and does not sign any transactions.

WHAT IT CANNOT SEE

The tool cannot actually place limit orders without a valid order book or DEX contract on the current chain — the order is simulated. It cannot provide real-time order matching without external API — the simulation does not include order matching. It cannot handle tokens with transfer fees or rebasing mechanisms accurately — the simulation assumes standard ERC-20 tokens. It cannot guarantee order execution or slippage — the simulation does not include market conditions. It cannot perform cross-chain limit orders — the tool only works on the current network. It cannot cancel or modify orders after creation — the simulation is static. It cannot retrieve real order book data. The tool is read-only and does not sign any transactions.

PLEASE NOTE

This tool works exclusively with EVM-compatible chains for the wallet connection, but the limit order simulation is chain-agnostic. Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported for wallet connection but the simulation works regardless. The tool provides a simulation — for real limit orders, use a DEX or order book exchange. The tool does not store any data — all operations are performed client-side. The tool is provided as-is with no warranty or liability. Always verify order parameters before placing real orders.
