ICX Maker Bot with Deno (Automatic Testing)

[izzycsy]

For users who would like to test ICX (InterChain Exchange) maker bot independently on their local repository, here’s a guide. For the purpose of this test exercise, Taker (the user), will be interacting with Maker (bot) to perform the transaction.

Before starting the test, ensure that you have:

• node synced with Testnet and enabled spv=1 in defi.conf file
• sufficient utxoDFI, tokenDFI, dBTC token and SPV (Simplified Payment Verification) BTC balance

After testing, if you’re using dBTC maker bot, you should receive BTC token for dBTC. Whereas if you’re using BTC maker bot, you should receive dBTC for BTC token. Essentially, dBTC maker is selling dBTC, and BTC maker; vice versa.

User role: Taker

1. Install Deno

https://deno.land/

2. Clone icx-makerbot repository into your local repository

https://github.com/DeFiCh/icx-makerbot

Prerequisite Parameters

Tips:

• Use Code Editor tool to take note the following parameters as you’ll be reusing several scripts
• Take note of the punctuation symbols, it should be printed as ' ' or " ", not “ ”

Open defi.conf in a Code Editor and retrieve the following parameters:

Mac — Go to Folder:
/Users/<username>/.defi/defi.conf

Windows:
C:\Users\<username>\.defi\defi.conf

Check in defi.conf that spv is enabled: spv=1

rpcaddress (rpcbind)=127.0.0.1
rpcport=8555
rpcuser=FXdChSOx
rpcpassword=1e4fb8343d563d6ce26a035dece3b4e03db407e433e8de8f9fd7e55c820edc399

From your DeFi Wallet, retrieve the following parameters:

dfi_address=tqEw2Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS
spv_btc_address=tb1q2pysdzz8667dv4qvptqnzvm07vw9purg0hwhy5
spv_getaddresspubkey=03a4728fae10976ad7b2288782e083d2204b16c0b631f3c82f37e22cbeae18zy70

• If you do not have an spvWallet Bitcoin address, run the following command in DeFi Wallet CLI
  spv_getnewaddress in DeFi CLI

• To retrieve your spvWallet public key, run the following command in DeFi Wallet CLI
  spv_getaddresspubkey <space> spvAddress in DeFi CLI

4. Run DeFi Wallet in the background

• Ensure that DeFi Wallet is 100% synced, and keep it running in the background

5. Prepare the script

• Using the prerequisite parameters (step 3) and script example provided, replace the respective parameters and separate each parameter with a space

Script example(s):

dBTC Taker

deno run --allow-all icx_bot_dbtc_taker.js rpc_address rpc_port rpc_user rpc_password dfi_address spv_btc_address

Example output:

BTC Taker

deno run --allow-all icx_bot_btc_taker.js rpc_address rpc_port rpc_user rpc_password dfi_address spv_btc_address

Using retrieved parameters it should look something like this:

• Separate parameters with a space

deno run --allow-all icx_bot_dbtc_taker.js 127.0.0.1 8555 FXdChSOx 1e4fb8343d563d6ce26a035dece3b4e03db407e433e8de8f9fd7e55c820edc399 tqEw2Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS tb1q2pysdzz8667dv4qvptqnzvm07vw9purg0hwhy5

6. To run dBTC maker bot using Deno

Run your Terminal, change directory to icx-makerbot (step 2) and run deno (step 5)

% cd icx-makerbot
icx-makerbot % deno run --allow-all icx_bot_dbtc_taker.js 127.0.0.1 8555 FXdChSOx 1e4fb8343d563d6ce26a035dece3b4e03db407e433e8de8f9fd7e55c820edc399 tqEw2Q9yGJ1UWCXdQcUwkwSX48mkvdV2sS tb1q2pysdzz8667dv4qvptqnzvm07vw9purg0hwhy5

Example output:
