CSV Support

The Sablier Interface provides a number of advanced features using templated CSV files. Bellow you can find a list of all these features that help automate medium to large scale distributions.

Formatting Caveats

Dates: All the columns that use the "date" type should have the following format: "YYYY-MM-DD HH:mm".

Durations: All the columns that use the "duration" type should have the following format: "x years y days z hours". Note that each particle is optional, e.g., you can skip the days.

Timezones: The dates and times extracted from the CSV are processed using the same timezone as the locales of the client's device.

Amounts: All the amounts should be expressed in humanized notion. They will be padded with the selected token's number of decimals in the processing step.

Streams: Create Group

Using a pre-configured CSV, deploy up to 60+ streams, all onchain, all at once. Start from the suggested template, fill in rows with addresses, amounts and other details. Finally, create batches/groups of streams in a single transaction.

Navigation

In order to access this feature you will need to:

1. Access the create streams gallery - make sure you're on the group tab (top right)
2. Click on the desired stream shape card
3. At the top (top-right) of the page you will find a button guiding you towards the CSV feature

Form Layout

The Create Group From CSV form consists of two parts:

Part 1: General Details

In this part of the form you should fill in the general details that all streams have in common. This step is similar to the regular create group forms, with the addition of a "timing" field that toggles between time configurations:

1. By duration: e.g. streams end 30 days from now
2. By range: e.g. streams being on start time and last until end time

Part 2: Streams

This area consists of a large file picker. As soon as a file is uploaded it displays a table containing every stream and its primary details.

info

To double-check all columns provided through the CSV, click on the table (or action button at the top) and open the expanded table view.

Working with the CSV template

For each stream shape and duration you can use a different CSV template. You can download this template directly from the form, pre-configured to the selected shape and timing option.

For convenience, here's a table with all the available templates:

URL	Description
Cliff exponential with duration	Cliff-Exponential streams with the duration timing.
Cliff exponential with range	Cliff-Exponential streams with the range timing.
Cliff with duration	Cliff streams with the duration timing.
Cliff with range	Cliff streams with the range timing.
Exponential with duration	Exponential streams with the duration timing.
Exponential with range	Exponential streams with the range timing.
Linear with duration	Linear streams with the duration timing.
Linear with range	Linear streams with the range timing.
Monthly with range	Unlock Each Month streams with the range timing.
Stepper with duration	Unlock In Steps streams with the duration timing.
Stepper with range	Unlock In Steps streams with the duration timing.
Timelock with duration	Timelock streams with the duration timing.
Timelock with range	Timelock streams with the range timing.
Unlock cliff with duration	Unlock-Cliff streams with the duration timing.
Unlock cliff with range	Unlock-Cliff streams with the range timing.
Unlock linear with duration	Unlock-Linear streams with the duration timing.
Unlock linear with range	Unlock-Liner streams with the duration timing.

Columns and Caveats

In order to properly use the CSV create feature you will have to provide data in the proper format for each column. Bellow you can find a list with each possible column, a short description and an example value.

info

If editing the CSV in Google Spreadsheets or similar applications, make sure that these formats are not overridden by the app itself. We suggest double-checking in the Sablier app that the dates have been parsed as expected.

Column	Description	Examples
address	String - recipient's address	0x12...AB
amount	Number - the amount that will be streamed	100, 2500, 42161 or any other valid amount.
duration	Duration type - string that denotes the duration of the stream	1 year 20 days, 3 years 20 days 4 hours
start	Date type - string that denotes the start date of the stream	2024-02-24 16:15, 2026-02-14 17:25
end	Date type - string that denotes the end date of the stream	2024-02-24 16:15, 2026-02-14 17:25
cliffDuration	Duration type - string that denotes the cliff duration of the stream	2 years 20 days, 3 years 20 days 4 hours
cliffEnd	Date type - string that denotes the cliff end date of the stream	2024-02-24 16:15, 2026-02-14 17:25
months	Number - the number of months for the unlock monthly	4, 5, 12 or any other valid integer.
steps	Number - the number of steps for the unlock in steps	4, 5, 12 or any other valid integer.
unlock	Number - the amount that will be initially unlocked	100, 2500, 42161 or any other valid amount.
initial	Initial unlock type - wether the first unlock should occur at the stream start date or at the end of the first month	at start or end of first month

Airstreams: Create

Using a pre-configured CSV, deploy tens of thousands of streams, all onchain, all in one campaign. Start from the suggested template, fill in rows with addresses, amounts and other details. Finally, create the airstream campaign in a single transaction. Recipients will be able to start claiming their streams as soon as the campaign is deployed and funded.

Navigation

In order to access this feature you will need to:

1. Access the create airstream page
2. Continue to the second step to enable uploading the CSV

Working with the CSV template

Working with the CSV template is pretty straightforward and similar to what we discussed in the previous guide (creating stream groups).

info

For now, creating airstreams is only possible using Lockup Linear contracts, no cliff and a "duration"-driven timing. Therefore, you don't have to worry about multiple templates or different configurations.

For convenience, here's a table with the main template:

URL	Description
Airstreams - Linear	Duration based template with linear streams
