AO Streamable Token Specification

This specification describes the necessary message handlers and functionality required for a streamable ao token process.

Token Process

A specification-compliant token process responds to a number of different forms of messages, with each form specified in an Action tag. The full set of Action messages that the standard token support can be found here and the additional Action messages are as follows:

Name	Description	Read-Only
CreateStream	initializing the stream	⤬
ProcessStream	updates the stream	⤬

In the remainder of this section the tags necessary to spawn a compliant token process, along with the form of each of the Action messages and their results is described.

---

Spawning Parameter

These additional compliant token processes must carry the following immutable parameters according to their Action Message upon spawning:

Name	Description	Action Message
Recipient	To whom you will send the vested amount	CreateStream
Quantity	The amount you want to vest	CreateStream
StartTime	The start date for vesting	CreateStream
VestingPeriod	The period for which you want to vest	CreateStream
StreamId	The ID of the current stream	ProcessStream

---

Streaming Protocol

CreateStream(Recipient, Quantity, StartTime, VestingPeriod, StreamId)

Creates the Stream object having all the following necessary fields for creating streamable token, like: Sender, Recipient, Quantity, StartTime, CurrentTime, VestingPeriod, EndTime, StreamId, FlowRate, TotalSent, Status

Example Action message:

    Send({
        Target = "{TokenProcess Identifier}", 
        Tags = {
           Action = "CreateStream", 
           Recipient = "{Wallet Address/Process Id}", 
           Quantity = "Quantity", 
           StartTime = "1720598400", 
           VestingPeriod = "300"
        }
    })

Example Response message:

    {
    Recipient = "hYmtonqVyVDnD1L5MxcOmLu06koAY09_4m5mP6SbqXw",
    Data-Protocol = "ao",
    Type = "Message",
    Action = "CreateStream-Success",
    Quantity = "10000",
    From-Process = "O3OKbgd2nGihccR8bVSyhjOuN6hp7YNpeoVm5pk76s0",
    Variant = "ao.TN.1",
    Pushed-For = "yLGmnPEp5j-vwZZKEK6so94DDgCa9vzW4DyunYUT0lI",
    From-Module = "Pq2Zftrqut0hdisH_MC2pDOT6S4eQFoxGsFUzR6r350",
    VestingPeriod = "300",
    Ref_ = "66",
    StreamId = "7"
    }

ProcessStream(StreamId)

In ProcessStream we are processing the stream using the StreamId and checking the status of the stream according to the timeline set by the creator, and after certain conditions are met, then the processing of the tokens start and distributing among the receiver's address happens and to check these conditions are met or not Cron is used to call the function.

Example Action message:

    Send({
        Target = {TokenProcess Identifier}, 
        Action = "Cron" 
    })

Example Response message:

{
   Recipient = "hYmtonqVyVDnD1L5MxcOmLu06koAY09_4m5mP6SbqXw",
   Data-Protocol = "ao",
   Type = "Message",
   Action = "CreateStream-Success",
   Quantity = "10000",
   From-Process = "ue_9spSt45p1CmmG_03ccmhJKoHEUwGhQQdTwOpY1SA",
   Variant = "ao.TN.1",
   Pushed-For = "-SNCIMXL9q6iY0ULO0sUkmcgeiaTYNWlHNDhnUfbt50",
   From-Module = "Pq2Zftrqut0hdisH_MC2pDOT6S4eQFoxGsFUzR6r350",
   VestingPeriod = "1000",
   Ref_ = "2",
   StreamId = "1"
}
