Abstract

The contract is used to determine the profit distribution strategy of multiple owners of DToken.

Motivation

There may be multiple owners of DToken on the chain, and each owner's share of profit distribution is different. The specific allocation can be set in this contract.

Specification

Methods

register

pub fn register(key: &[u8], param_bytes: &[u8]) -> bool{}

Register the dividend distribution strategy on the chain.

The RegisterParam is defined as follow:

#[derive(Encoder, Decoder)]
pub struct RegisterParam {
    addr_amt: Vec<AddrAmt>,  //Address and share for agreed profit distribution
    token_type: TokenType,   //The currency used for the agreed fee. Ont, ong and oep4 are currently supported
    contract_addr: Option<Address>,//If it is an oep4 token, the address where the oep4 contract needs to be executed
}
#[derive(Encoder, Decoder, Clone)]
pub struct AddrAmt {
    to: Address,
    weight: u32,
    has_withdraw: bool,
}

The parameters are of the following type:

Parameter Type Description
key &[u8] also called resource_id in the other contract, used to mark the uniqueness of dividend strategy
param_bytes &[u8] the serialization result of FeeSplitModel

Event

This method will launch the following events:

["register", key, param_bytes]

getRegisterParam

pub fn get_register_param(key: &[u8]) -> RegisterParam{}

Query RegisterParam by key.

The parameters are of the following type:

Parameter Type Description
key &[u8] key is also called resource_id in the other contract, used to mark the uniqueness of dividend strategy

transfer

pub fn transfer(from: &Address, key: &[u8], amt: U128) -> bool{}

Transfer token assets to current contract address.

The parameters are of the following type:

Parameter Type Description
from &Address buyer address
key &[u8] Commodity ID
amt U128 Fees paid by the buyer

Event

["transfer", from, key, amt]

getBalance

pub fn get_balance(key: &[u8]) -> U128{}

Query balance by commodity ID

Parameter Type Description
key &[u8] commodity ID

withdraw

pub fn withdraw(key: &[u8], addr: &Address) -> bool{}

The data owner withdraw token from the contract.

Parameter Type Description
key &[u8] commodity ID
addr &Address the address who withdraw token, need the address signature

Event

["withdraw", key, addr]

transferWithdraw

pub fn transfer_withdraw(from: &Address, key: &[u8], amt: U128) -> bool{}

The buyer pays the fee and sends the fee directly to the data owner.

Parameter Type Description
from &Address buyer address
key &[u8] commodity ID
amt U128 Fees paid by the buyer

Event

["transferWithdraw", from, key, amt]
