Sablier Airdrops

Sablier Airdrops is a collection of EVM smart contracts for distributing ERC-20 tokens via Merkle trees, with optional vesting through the Sablier Lockup protocol.

Introduction

Sablier Airdrops is a collection of smart contracts that allows airdrops of ERC-20 tokens using Merkle trees. It offers multiple distributions options, including:

1. Instant airdrops: The simplest way to distribute tokens to a list of addresses. Eligible users can claim and receive their allocation instantly via a single claim transaction.
2. Vesting airdrops: This is the way to go if you want your users to receive tokens over time through vesting. Upon claiming, eligible users will have their tokens streamed through Sablier over a period specified by the campaign creator (aka the campaign owner). This distribution option has been referred to as Airstreams in the past.
3. Variable Claim Amount (VCA) airdrops: This distribution method allows the campaign creator to set up an airdrop with linear unlock. However, when a user claims their airdrop, any unvested tokens are forfeited and returned to the campaign creator. This approach is useful for airdrops aimed at rewarding loyal users who wait until the end of the unlock period to claim their tokens.

Sablier Airdrops also offer flexibility in configuring the Airdrop campaigns. For example, you can choose between whether you want vesting to begin at the same time for all users (absolute) or at the time of each claim (relative).
