Digital assets can exist in various forms, but the Sablier Protocol exclusively supports the streaming of ERC-20 assets.
The stream itself is represented as an NFT (ERC-721).
A third-party entity that interacts with the Sablier Protocol on behalf of its users, who may charge service fees for facilitating these interactions.
The fees collected by the broker upon creating a stream for their users.
The cut-off point for releasing assets. Prior to the cliff, the recipient cannot withdraw, though assets continue to accrue in the stream.
Sablier contracts that are considered foundational, and are essential for Sablier to exist. Upgrading to a new version of core would require deploying an entirely new set of smart contracts, and would be considered a new version of the Sablier Protocol.
Short for Decentralized Finance: an ecosystem of financial applications and services built on blockchain networks, primarily Ethereum, that leverage smart contracts to enable trustless, permissionless, and transparent financial transactions without relying on traditional intermediaries like banks or financial institutions.
The time when a stream is scheduled to end.
ERC-721 tokens are non-fungible tokens ("NFTs") on Ethereum. Sablier streams are represented as NFTs.
A global, open-source platform for decentralized applications.
Ethereum Virtual Machine
The technical architecture of Ethereum, which many other blockchains have appropriated.
Foundry is the application development toolkit that has been used to develop the Sablier Protocol.
Gas fees are transaction fees paid to the blockchain validators in native tokens such as ETH. Sablier Labs does not take any cut from this.
Gas is paid only when streams are created, canceled, transferred, or withdrawn from. It does not accrue in real-time.
A term coined by us to refer to the requirement of locking up assets in order to create a stream.
A Lockup stream with a payment rate per second that can vary over time.
A Lockup stream with a constant payment rate per second.
A milestone is the time component of a segment, which itself is a component of a Lockup Dynamic stream.
Milestones play a crucial role in the calculation of the custom streaming curve.
A protocol invariant that states that the total amount of assets released by the stream can only increase over time and never decrease.
Sablier contracts that are useful, but not required for Sablier to exist. New periphery contracts can always be deployed without migrating streams.
An entity with exclusive access to specific functions of the protocol.
A renounced stream is a stream that cannot be canceled anymore.
PRBMath is fixed-point arithmetic library used by Sablier Core to compute percentage values and the exponents used in Lockup Dynamic.
PRBProxy is a proxy contract that can compose transactions on behalf of the owner. PRBProxy is a key component of Sablier Periphery.
Fees that are rewarded to the Sablier Protocol itself.
The range of a Lockup Linear stream consists of three components: (i) the start time, (ii) the cliff time, and (iii) the end time.
The range of a Lockup Dynamic stream is determined by combining (i) the start time, (ii) the segment milestones, and (iii) the end time.
A term coined by us in 2019 to emphasize the wide-ranging use cases for the Sablier Protocol.
Since the withdrawable amounts in streams are updated every second, they embody the concept of real-time financial transactions.
A data object that encapsulates three properties:
Segments are an essential component of Lockup Dynamic, as they facilitate the calculation of the custom streaming curve.
The time when a stream is scheduled to start.
A stream can have one out of four possible statuses:
A new financial primitive that permits by-the-second payments.
Currently, the Sablier Protocol offers a single type of stream called a lockup stream, in which the creator has to lock up a specified amount of assets.
One of the most popular use cases for streaming today.
The purpose of vesting is to delay gratification. Founders, investors, and employees must wait a certain amount of time before being able to access tokens.
