Trading via Etherscan

Pika Protocol is a fully decentralized and permission-less exchange, operated not by team, but by unstoppable code. In the rare case when the website server is down, you can always trade directly with the smart contract from block explorers like Etherscan.

Preparation

If you have previously approved the contract in Pika UI, you can skip this step.

Approve Pika Contracts for USDC

To approve the contract, you first open the USDC contract on Etherscan: https://optimistic.etherscan.io/token/0x7f5c764cbc14f9669b88837ca1490cca17c31607#writeContract

Then clicks Connect to Web to connect to your Metamask wallet.

You need to click the Approve function 4 times to approve these 4 addresses:

1. PikaPerpV4 address: 0x9b86B2Be8eDB2958089E522Fe0eB7dD5935975AB

2. PositionManager address: 0xb67c152e69217b5acb85a2e19df13423351b0e27

3. OrderBook address: 0x835a179a9E1A57f15823eFc82bC460Eb2D9d2E7C

4. PositionRouter address: 0xa78Cd820b198A943199deb0506E77d655b5078cC

The amount is your intended trade amount. If you want to trade 100 USDC, the input amount should be 10000000000(100*1e8).

Enable Trading

You need to open the PikaPerpV4 contract: https://optimistic.etherscan.io/address/0x9b86b2be8edb2958089e522fe0eb7dd5935975ab#code and call setAccountManager twice to enable the trading for market, limit and stop orders:

1. Call setAccountManager function by setting _manager as the PositionManager contract address(0xb67c152e69217b5acb85a2e19df13423351b0e27) and _isActive is true.

2. Call the setAccountManager function by setting _manager as the OrderBook contract address(0x835a179a9E1A57f15823eFc82bC460Eb2D9d2E7C) and _isActive is true.

To enable placing market orders together with take profit and stop loss orders, you need to send two additional transactions:

1. Open the positionManager contract: https://optimistic.etherscan.io/address/0xB67c152E69217b5aCB85A2e19dF13423351b0E27 and call setAccountManager function, _manager is the positionRouter contract: 0xa78Cd820b198A943199deb0506E77d655b5078cC

2. Open the orderbook contract: https://optimistic.etherscan.io/address/0x835a179a9E1A57f15823eFc82bC460Eb2D9d2E7C and call setAccountManager function, _manager is the positionRouter contract: 0xa78Cd820b198A943199deb0506E77d655b5078cC
