Sablier on Solana
Sablier on Solana is in Maintenance Mode. The Solana programs are no longer actively developed or supported. Creating new streams and airdrop campaigns is no longer supported.
Introduction
Welcome to the Sablier on Solana documentation.
This section assumes you are familiar with the Sablier Protocol and its Ethereum high level concepts. Here, we focus on what's specific to the Solana blockchain and how it differs from Ethereum.
For more information on the original Sablier Protocol, refer to the main documentation. You can also find information about Streaming and Airdrops in the Concepts section.
App
The Solana app is available at solana.sablier.com for interacting with existing streams and airdrop campaigns.
SolSab
SolSab is a collection of Solana programs featuring two protocols: Sablier Lockup and Sablier Merkle Instant.
Lockup
Sablier Lockup is a token distribution protocol that enables onchain vesting and payments. Our flagship model is the linear stream, which distributes tokens on a continuous, by-the-second basis.
The way it works is that the stream creator first deposits a specific amount of SPL/Token2022 tokens. The program, then, progressively transfers the ownership of the funds to the recipient (who can withdraw them as they're streamed). The streaming rate is influenced by various factors, such as the start and end times, the total amount of tokens deposited, etc.
Key differences from the Ethereum Lockup protocol
- On Solana, we currently support all shapes from the Lockup Linear category, as well as the Timelock shape (also implemented via the Linear program).
- Due to the limitations of the Token Metadata NFT standard, we don't support non-transferable Streams on Solana.
- Instead of the tokens from all of the streams being stored at a single address, on Solana, they're kept in dedicated stream ATAs (Associated Token Account).
- Due to how Solana's VM works, we do not support hooks for the
cancelandwithdrawfunctionalities.
Merkle Instant
The Merkle Instant program enables the creation of Merkle Tree-based token airdrop campaigns that allow users to claim their entire allocation at once after the campaign starts.
Key differences from the Ethereum Airdrops protocols
- The Solana protocol only includes the Instant airdrop model.
- Due to Solana’s account architecture, a single program handles both creation and claiming. In contrast to Ethereum, where a factory contract deploys a stand-alone contract for each airdrop campaign, and claiming is performed on that contract.
