Fixed Amount Splitter

Introduction

The Fixed Amount Splitter ADO is a smart contract used to split funds to a preset number of addresses. Each of the addresses has a specific amount assigned by the contract owner. Once a Send message is triggered, the attached funds are distributed to the recipients based on the assigned amounts.

The splitter can be locked for a specified time as a kind of insurance for recipients that their amounts will not be changed for a certain period of time.

Splitter works with both native and CW20 tokens.

We also have a percentage based spliiter.

Splitting CW20 Tokens

To setup a CW20 split, you need to define the denom of the Coin as the contract address of the CW20 ADO whose token you are splitting. In case this address is not present yet (You are creating the CW20 ADO and Splitter ADO at the same time), you need to:

1. Initialized the ADO with any recipient list.

2. Update the recipient list by calling UpdateRecipients.

3. Specify the coin denom field as the CW20 contract address.

Example Uses

Let’s say you’re running a small team and want to pay monthly salaries. You can set up the Fixed Amount Splitter once, assigning fixed amounts to each team member’s address (e.g., Alice: 2,000 USDC, Bob: 3,000 USDC, etc.). Then at the end of each month, you simply trigger a single Send, and everyone receives their salary in one transaction.

This ADO is also ideal for managing fixed recurring costs. For example, if your application needs to pay fixed amounts monthly (e.g., hosting, data, analytics tools), you can configure it once and distribute those payments on demand with just one click.

Name	Type	Description
recipients	Vec<AddressAmount>	The recipient list of the splitter. Can be updated after instantiation if there is no current lock time.
lock_time	Option<Expiry>	How long the splitter is locked. When locked, no recipients can be added/changed.
default_recipient	Option<Recipient>	An optional recipient to receive any leftover funds in case the split is not exactly distributed or there are any leftover funds. Defaults to the sender if not specified.
kernel_address	String	Contract address of the kernel contract to be used for AMP messaging. Kernel contract address can be found in our deployed contracts.
owner	Option<String>	Optional address to specify as the owner of the ADO being created. Defaults to the sender if not specified.

Anytime a Send execute message is sent, the amount sent will be divided amongst the recipients depending on their assigned amounts.

AddressAmount

The splitter uses a basic array of structs to determine recipients and how the funds are divided.

For the Coin struct, use the contract address as the denom in case you are using CW20 tokens.

Rust

pub struct AddressAmount {
    pub recipient: Recipient,
    pub coins: Vec<Coin>,
}

JSON

{
    "recipient":{
        "address":"andr1..."
     },
    "coins":[{"denom":"uandr","amount":"10000"}]
}

ExecuteMsg

Receive

Receives CW20 tokens sent from a CW20 ADO by performing a Send. These tokens are then automatically split to the defined recipients of the splitter.

Rust

pub enum ExecuteMsg {
    Receive(Cw20ReceiveMsg),
   }

Cw20ReceiveMsg

pub struct Cw20ReceiveMsg {
    pub sender: String,
    pub amount: Uint128,
    pub msg: Binary,
}

The msg in the Cw20ReceiveMsgshould be a base64 encoded Cw20HookMsg.

Cw20HookMsg

pub enum Cw20HookMsg {
    Send { config: Option<Vec<AddressAmount>> },
}

Send (CW20)

Distributes sent CW20 funds amongst the recipients list based on their assigned amounts.

Make sure you are sending CW20 tokens from the CW20 ADO defined in the denom field of the Coin struct.

Rust

pub enum Cw20HookMsg {
    Send {
         config: Option<Vec<AddressAmount>> 
    },
}

JSON

{
"send": {}
}

Name	Type	Description
config	Option<Vec<AddressAmount>>	An optional set of recipients/amounts to use. If not defined, then the default configuration will be used.

Only available to the contract owner when the contract is not locked.

A maximum of 100 recipients can be set.

The recipients should be unique.

Rust

pub enum ExecuteMsg {
    UpdateRecipients { 
        recipients: Vec<AddressAmount>

    }
}

Name	Type	Description
recipients	Vec<AddressAmount>	The new list of addresses to receive funds.

UpdateLock

Used to lock the contract for a certain period of time making it unmodifiable in any way. This can serve as a way to ensure for recipients that their weights from the splitter are fixed for a certain amount of time. The time is calculated in seconds.

Only available to the contract owner when the contract is not already locked.

The minimum time that can be set is 86,400 which is 1 day.

The maximum time that can be set is 31,536,000 which is 1 year.

Rust

pub enum ExecuteMsg {
    UpdateLock {
        lock_time: Expiry,
    },
}

JSON

{
    "update_lock": {
        "lock_time":{
            "from_now": 6000000
        }
    }
}

Name	Type	Description
lock_time	Expiry	How long the splitter is locked. When locked, no recipients can be added/changed.

Send (Native)

Divides any attached funds to the message amongst the recipients list based on the assigned amounts.

Only available to the contract owner.

Rust

pub enum ExecuteMsg {
  UpdateDefaultRecipient {
        recipient: Option<Recipient>,
    },
}

JSON

{
    "update_default_recipient": {
        "recipient":{
            "address":"andr1..."
            }
        }
}

Name	Type	Description
recipient	Option<Recipient>	The new recipient to receive any leftover funds in case the split is not exactly distributed. For example if a user sets 40% to one user, and 50% to another, and forgets about the last 10%, they would go this default recipient. Defaults to the sender if not specified.
