CF-20 is a format and standard of interchangeable tokens developed by us for the Cellframe Network platform. Tokens of the CF-20 standard can be used for settlements, exchanges, proof of stake and many other functions within the Cellframe Network.
Important
For more information about the Cellframe Network you can refer to the Architecture Overview page
Every token in the Cellframe network is based on this standard including CELL, KEL, and other tokens (in the test networks). CF-20 standard is an analogue of ERC-20, but without smart contracts, which could be entangled later with token.
- CELL is a native token in the Backbone network
CELL can be used for providing functionality of every service in the Cellframe Ecosystem
Functional
Technical functionality and properties of the CF-20 standard is described in the dap_chain_datum_token.c file of the Cellframe SDK. It is integrated in the very blockchain.
All our CF-20 tokens support functions, almost similar to the same in the ERC-20 standard.
Some changeable parameters are created in our tokens as mandatory (total_supply, valid_signs, type, ticker, etc) while others are realized using different flags.
Flags can significantly alter token properties, such as allowing or restricting fund transfers to/from specific addresses and many more.
Let’s use the TOKEN_INFO CLI command for acquire some information about CELL token:
current state:
-->Token name: CELL
type: CF20
flags: NONE
description: The token description is not set
Supply total: 0
Decimals: 18
Auth signs valid: 4
Auth signs total: 8
Signatures public keys:
#below there is a list of applied public keys and information about token updatings
...Here is the parameters description:
-Token name - ticker (name) of the token
-type - type of the token (CF20 by default)
-flags - different token properties (<ALL_ALLOWED> by default)
-description - token description
-Supply total - maximum sum limit of all token emissions (if 0 - there is no limit)
-Decimals - number accuration after comma (18 by default)
-Auth signs valid - quantity of authorized token signatures required for its emission
-Auth signs total - quantity of authorized token signatures
-Signatures public keys - public certificates which were used to sign token
Most of these fields can be changed using TOKEN_UPDATE command.
Important
Additional information about flags and used datums you can find in the CF-20 Functional Application article.
Bridge
Also, CF-20 standard is used for providing bridge communication among our networks, and between ours and other networks.
Official site of the Cellframe Bridge - https://bridge.cellframe.net/
Explorer
Cellframe Explorer also works with CF-20 standard. All interactions with CF-20 tokens can be tracked and seen on the site - https://explorer.cellframe.net/.
DEX
As said previously, all CF-20 tokens are tradable. Not only using our Decentralized Exchange, but on the external exchanges as well. Here is the example in our DEX of token pair CELL/KEL which both have CF-20 format.
Interaction
All interaction with the Cellframe node and CF-20 tokens as well is based on the CLI-Commands and JSON-RPC requests.
For interaction via JSON-RPC we developed WEB3 API, which is must a have for developers and projects. This API is designed for providing following interaction:
Request is just a usual GET request on localhost:8045
Interaction with Cellframe node via WEB queries is really efficient and convenient.
