Installation

npm install -g cfox

Initialization

cfox will ask the user to set the password on its first run:

  ______  _______   ______   ___   ___
 /      ||   ____| /  __  \  \  \ /  /
|  ,----'|  |__   |  |  |  |  \  V  /
|  |     |   __|  |  |  |  |   >   <
|  `----.|  |     |  `--'  |  /  .  \
 \______||__|      \______/  /__/ \__\
                             CFox 0.0.4

cfox=#
This is your first time to run cfox, please do some configurations first.
Please set login password: ***
Please confirm the password: ***
cfox=#
Please input password: ***
Login successfully!

After that, since there are no wallets added the prompt will use ? for current wallet:

cfox[?||mainnet]=#

The prompt format: cfox[current_wallet || current_network], both will be used by the provider or signer running the blockchain related command. You can use \c to change them.

Now, it's time to create a wallet for playing. The simplest way is to run \a -a, which will create an random wallet and set it the current wallet because there is no one.

cfox[?||mainnet]=# \a -a
✔ try to create a new account.
cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mainnet]=#

The last step of initialization is to set the keys used by cfox. You can find all the external apis supported by running keys -l. Currently, the result:

cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mainnet]=#keys -l

| name        | value |
-----------------------
| infura      |       |
| morails     |       |
| nft.storage |       |

Tip:

You can always find the saved data in the home directory of cfox: "${USER_HOME}/.cfox".

For example, it is "~/.cfox" on linux or macos.

Commands

Each command has a detailed description and you can always know it by running help <command> or <command> --help. For example:

cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mainnet]=# help qr

  Usage: qr [options] [account]

  Generate a QR Code for an account, current account will be used when account is missing.

  Options:

    --help  output usage information

The commands using the external apis:

• nft, it will use morails as a fallback for those contracts not implementing IERC721Enumerable.
• upload, it depends on nft.storage api to fulfill uploading datas to IPFS.

Tips:

1. All command line arguments will be splitted by space.
2. When passing arguments to an event query, missing means null.

Example #1: query all Transfer events in an range.

cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mumbai]=#query 0x0dc5a5d352e55dbb3d27c462de6b506517b86443
Event Abi: event Transfer(address indexed from, address indexed to, uint256 value)
event args (address,address):
start block (top n blocks if it is negative.): 30037846
end block: 30038856
✔ try to query event Transfer().

...

Example #2: query all Transfer(,to) events in an range.

cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mumbai]=# query 0x0dc5a5d352e55dbb3d27c462de6b506517b86443
Event Abi: event Transfer(address indexed from, address indexed to, uint256 value)
event args (address,address):  0x3B057FD4Ba20D2129b1DD5355CEDE95D4E990ab4
start block (top n blocks if it is negative.): 30037846
end block: 30038856
✔ try to query event Transfer(,0x3B057FD4Ba20D2129b1DD5355CEDE95D4E990ab4).

...

Example #3: query all Transfer(from) events in an range.

cfox[0xBED16Cd70529D459f4A1A44D6Fe0c6B41364a00C||mumbai]=# query 0x0dc5a5d352e55dbb3d27c462de6b506517b86443
Event Abi: event Transfer(address indexed from, address indexed to, uint256 value)
event args (address,address): 0x0000000000000000000000000000000000000000
start block (top n blocks if it is negative.): 30037846
end block: 30038856
✔ try to query event Transfer(0x0000000000000000000000000000000000000000).
