Introduction

For ICON to be able to manage where to send it inflation in versatile manner it needs a contract which can in a configurable way distribute to many sources.

Goloop can current assign inflation to 3 buckets

• Validator/Staking rewards
• CPS
• IRelay

This IRelay bucket is what this contract aims to fill. Where we have one contract that can relay inflation to any source decided by the network.

Overview

ICON inflation flow:

Buckets Contract Overview:

Requirements

• The contract has to be owned by ICON Governance
• The contract should have configurable buckets only configurable by the owner of the contract
• The contract should have a public distribution method that distributes the inflation to defined buckets.

Design

Storage and Structs

public ArrayDB<Bucket> buckets;

Bucket {
    String name
    Address address
    BigInteger inflationShare
}

Methods

/**
 * Configures the inflations buckets.
 *
 * @param _buckets a list of all buckets for the current configuration.
 */
@External
public void configureBuckets(Bucket[] _buckets) {
    OnlyICONGovernance();
    Assert sum(_buckets.inflationShare) == EXA
    Assert for each (_buckets.inflationShare >= 0)

    buckets.clear();
    buckets.addAll(_buckets);
}

/**
 * Distributes inflations to all currently configured buckets
 *
 */
@External
public void distribute() {
    balance = Context.getBalance();
    for each bucket in this.buckets {
        share = bucket.inflationShare * balance / EXA;
        Context.transfer(bucket.address, share);
    }
}
