Introducing Instant Airdrops

In 2024, we pioneered Airstreams, a groundbreaking solution for running vested airdrop campaigns with ERC-20 tokens. Airstreams has since empowered hundreds of organizations to distribute tokens to hundreds of thousands of recipients.

Among this wide adoption of Airstreams, we got one specific feature request over and over again: instant airdrop distributions with no vesting. Today, we’re pleased to launch our Instant Airdrops product.

Along with it, we’re introducing a unified contract architecture, massively simplifying our codebase, as well as a new pricing system to ensure Sablier’s sustainability.

Instant Airdrops

On top of linearly vesting an airdrop, or unlocking it in steps, users now have the ability to airdrop tokens instantly.

Instant Airdrops require just one claim action—initiated either by the recipient or any account willing to pay the fees—to receive the full airdrop allocation. This differs from vested airdrops (Airstreams), where the claim transaction creates a Sablier stream that distributes tokens over time.

This new feature is designed to cater to scenarios like:

• Immediate token distribution: community rewards, token launches, etc.
• Engaging liquidity providers: to reward LPs on DEXs without requiring ongoing vesting.
• NFT and gaming rewards: enable seamless distribution of an in-game currency or governance tokens for GameFi projects and NFT holders.

Thanks to Instant Airdrops, Sablier users now have full control over how they want to distribute their airdrops, whether instantly or via vesting.

Unified Lockup Architecture

As part of our continuous effort to simplify and optimize the Sablier protocol, we are introducing a new smart contract: Lockup. This contract merges the Lockup Linear, Lockup Dynamic, and Lockup Tranched contracts, aggregating their functionality into a single, more efficient monolith contract.

By consolidating these separate contracts, we achieve:

• A more developer-friendly codebase: reducing complexity and making integrations more developer-friendly by having a single contract to be integrated with, as opposed to three different ones.
• Improved gas efficiency: merging contracts lowers the overhead.
• Greater flexibility: Lockup maintains the core features of each previous contract while offering a unified interface that supports linear, dynamic, and tranch-based unlocking.

With the new unified Lockup, projects can still configure their vesting schedules to fit their needs, but with a simpler, more powerful contract architecture.

New Pricing Model

For the five years, Sablier has been entirely free to use. As we continue to grow and improve our protocol, we are introducing a new fee model to ensure long-term sustainability while maintaining our commitment to efficiency and security.

Importantly, the fee model is not retroactive—withdrawals from streams and claims from airdrops created via the UI before February 3, 2025 will remain free forever, thanks to the immutability of the smart contracts.

Under this new model:

• Creating streams and deploying airdrop campaigns will continue to be free.
• Claiming an airdrop will cost $3.
• Withdrawing from a stream will cost $1.
• Typically, recipients of a stream or airdrop perform these actions. However, since the withdraw and claim functions are public, any account can call them.
• The fees are paid in the chain’s native currency, the same used for gas fees (e.g., ETH on Ethereum, POL on Polygon).

To provide greater flexibility, stream creators can sponsor these fees for their recipients, even after the streams are created. If you’re interested in covering these costs for your users, reach out to us on Discord or schedule a call with our sales team.

The new pricing model allows us to continue building the best user experience for onchain token distribution while keeping our infrastructure scalable and cost-effective.

In Conclusion

Instant Airdrops provide a seamless way to distribute tokens without vesting constraints, while the new Lockup unifies our contract architecture, making it easier and more cost-effective for projects to integrate our codebase.

Our new pricing system ensures long-term sustainability while keeping fees transparent and manageable, with the option for users to sponsor costs for their recipients.

If you have any questions or want to explore how these new features can benefit your project, join us on Discord—we’d love to hear from you. Thank you for being part of Sablier’s journey.
