FAQ

Where can I access the Sablier protocols?​

You can access Sablier through the following web interfaces:

What is real-time finance?​

A term coined by us to emphasize the wide-ranging use cases for the Lockup protocol. We like to think about work as an attempt to rethink the way trust is established in financial contracts.

What is token streaming?​

An alternative wording, coined by Andreas Antonopoulos in 2017. Just like you can stream movies on Netflix or music on Spotify, so you can stream tokens by the second on Sablier.

How does streaming work on Sablier Lockup?​

Imagine Alice wants to stream 3,000 DAI to Bob during the whole month of January.

  1. Alice deposits the 3,000 DAI in Lockup before Jan 1, setting the end time to Feb 1.
  2. Bob's allocation of the DAI deposit increases every second beginning Jan 1.
  3. On Jan 10, Bob will have earned approximately 1,000 DAI. He can send a transaction to Lockup to withdraw the tokens.
  4. If at any point during January Alice wishes to get back her tokens, she can cancel the stream and recover what has not been streamed yet.

How does streaming work on Sablier Flow?​

Coming soon.

How can I create a stream?​

You will need an EVM wallet (Metamask, Rainbow, etc.), some ETH (or the network's token to pay gas fees) and an ERC-20 token like DAI. Then, choose your favorite interface for accessing the Sablier protocols (such as app.sablier.com) and fill in the recipient's address, the deposit amount and the total duration.

Alternatively, you can see here how to manually create a stream using Etherscan.

How does Lockup streaming work?​

Dividing the deposit amount by the difference between the stop time and the start time gives us a payment rate per second. Lockup uses this rate to transfer a small portion of tokens from the sender to the recipient once every second.

For instance, if the payment rate was 0.01 DAI per second, the recipient would receive:

0.01∗60=0.60.01 * 60 = 0.6 DAI / minute, 0.01∗60∗60=360.01 * 60 * 60 = 36 DAI / hour, 0.01∗60∗60∗24=8640.01 * 60 * 60 * 24 = 864 DAI / day

Where are the tokens held?​

In our smart contracts. You can verify this assertion by inspecting Etherscan or any other blockchain explorer.

How can recipients access their tokens?​

As the tokens are being streamed at the smart contract level, recipients can consider Sablier their real-time wallet for digital currency.

To make withdrawals, recipients can:

  1. Use a web interface (e.g. app.sablier.com).
  2. Call the contract directly on a blockchain explorer.

Can I cancel streams?​

Yes, both as a sender and a recipient.

If the stream is canceled before the start time, the whole deposit amount is returned in full to you. If the stream is canceled while the stream is active, the smart contracts calculate how much has been streamed, transfer that to the recipient and return the remainder to you. If the stream is canceled after the stream has stopped, the smart contracts transfers all the remaining funds (if any) to the recipient.

Can I modify the streaming rate?​

On Lockup, once a stream is created, it is set in stone on the Ethereum blockchain. Whereas on Flow, a stream rate per second can be modified anytime by the creator.
