Zero-knowledge rollups (ZK-rollups) could be one of the strongest performing sectors in 2023, as demand for Ethereum scaling solutions is increasing. As such, Scroll is another highly anticipated ZK-rollup project that has recently hinted at a token airdrop. Scroll have recently announced they have launched their Sepolia testnet. This is the final stage before mainnet, which is rumoured to be in September 2023. As the potential for ZK-rollups is massive this year, this is a good opportunity for you to earn free airdrop rewards.
If you are interested in other trending ZK-rollup projects, zkSync and StarkNet should definitely be on your watchlist for 2023.

What is Scroll?
Scroll is developing a ZK-rollup that is fully compatible with the Ethereum Virtual Machine (EVM). Their proving system supports the direct verification of an Ethereum block with a single, concise proof. This means much faster Ethereum transaction finality and less gas fees.
How Does Their ZK-Rollup Work?
The concept involves verifying the accuracy and completeness of each operation code in the EVM execution trace. As a result, layer-1 smart contracts can be easily transferred to Scroll. Instead of incorporating new ZK-specific features, they will take a different approach by supporting the native EVM with tailored optimizations. This gives them a significant advantage as they can work seamlessly with all existing Ethereum systems without the need for any modifications.
Layer-2 Proof Outsourcing
Scroll also aims to establish and standardize the outsourcing of layer-2 proofs, which streamlines rollup processes. They have created a strong outsourcing system that motivates rollers to produce zero-knowledge proofs for them. They will standardize this approach to accommodate a wider range of off-chain computations. This will create a new proof market.
Another benefit for developers is that they can deploy complex contracts on Scroll without worrying about gas limits. This opens up many new possibilities for off-chain applications with on-chain proofs.
Key Takeaway of Scroll’s Proof System
Based on the two points mentioned above, Scroll is a hierarchical zero-knowledge proof system. The first layer will be optimized for prover efficiency, utilizing custom circuit optimization and hardware-friendly proving algorithms. The second layer will be optimized for verifier efficiency, featuring succinct proofs and verification algorithms that are compatible with the Ethereum Virtual Machine (EVM).
This proof system has the potential to support larger programs than the EVM and offer additional features such as privacy, surpassing the capabilities of existing solutions.
Who is the Team behind Scroll?
Scroll is co-founded by Sandy Peng, Ye Zhang, and Haichen Shen. Peng has rich experience in business development, project strategy and data curation. On the other hand, Zhang and Shen are experts in computer science, open-source protocol engineering, and cryptography. Shen, in particular, previously worked for Amazon as a senior applied scientist on AI compilers.
In April 2022, Scroll successfully raised $30 million in a Series A funding round led by Polychain Capital and Bain Capital Crypto, with participation from Robot Ventures and Geometry DAO. As of now, their team has at least 20 people across the globe who are experts in zero-knowledge cryptography and distributed systems on blockchain technology.
Does Scroll have a Token?
Scroll does not have a token yet, but it is expected to be released around the mainnet launch in August 2023. According to their roadmap published on Discord, they mentioned that they are creating an incentive mechanism to encourage participation in the network. This strongly indicates that there will be a token coming soon, and airdrops will be rewarded for early users.
How to Get the Potential Scroll Token Airdrop?
The best way to get the potential Scroll token airdrop is to interact with the recently launched Alpha Testnet. Here’s a step-by-step guide:
- Add Scroll Alpha Testnet to MetaMask
Go to the Scroll Alpha Testnet portal, and add the L1 and L2 configurations to your wallet.
Add the Scroll Alpha Testnet to Metamask- the network configuration details are here. If you have added the Pre-Alpha Testnet network before, you will need to remove it from your MetaMask before proceeding. Afterwards, reset MetaMask for Scroll’s L2. - Claim Goerli ETH from Goerli Faucet
In case you haven’t added the Goerli network to your MetaMask, you can do it via ChainList.
Now, you will need Goerli ETH on your wallet. Request them at any Goerli faucets such as Alchemy or Goerli PoW. - Bridge Goerli ETH to Scroll L2
Use the Scroll Bridge to transfer testnet ETH tokens from Goerli Testnet to Scroll Alpha Testnet. The transaction will take around 10-15 minutes.
You can check your transactions on the Scroll Rollup Explorer. - Bridge Scroll L2 to Goerli
While on the Scroll Alpha Testnet network, you can also do the reverse of step no.3 i.e. bridge your testnet ETH tokens back to the Goerli Testnet.
- Send ETH to another wallet using MetaMask
Send ETH from one wallet to another on the Scroll Network using Metamask.
- Interact with Scroll Ecosystem
Scroll has a large ecosystem of projects. Interacting with them generates on-chain evidence that can help you qualify for a potential airdrop. Some examples include Aave, Syncswap, Izumi Finance and Symbiosis (see below). Here’s a list of the Scroll ecosystem projects.
- Use Scroll Alpha on Aave
Connect your wallet to Aave, then click the settings button on top right hand corner and turn on Testnet Mode. Then, click the down arrow on the left hand side and choose “Scroll Alpha” for the Aave Testnet Market. Finally, supply and borrow some tokens such as ETH, DAI, USDC and USDT.
- Use Scroll Alpha network on SyncSwap
Connect your wallet to SyncSwap and choose the Scroll Alpha network on the top right hand side. Click on “Faucet” and “Claim now” to get testnet tokens. Note you will need ETH to cover gas fees. Perform some swaps on the “Trade” tab, add liquidity to some pools on the “Pool” tab and remove part of the liquidity.
SyncSwap may also be doing its own $SYNC token airdrop! Learn more here! - Interact with Izumi Finance
Connect your wallet to Izumi Finance. On the “Swap” tab, swap between tokens such as ETH, USDT, WETH, USDC and IZI. Then, go to the “Pro” tab to access their exchange. On the exchange, make some limit orders. Finally, click on “Liquidity” and add liquidity.
- Perform swaps and add liquidity using Symbiosis
Perform swaps on Symbiosis exchange. Also add liquidity to their Liquidity Pools. Remember to do this with Scroll tokens only! You can tell which tokens are Scroll tokens since they will have the 📜 emoji on them.
- Get Scroll Guild roles
Go to the Scroll Guild Page. Connect your wallet, Discord and Twitter accounts. Complete the tasks to earn guild roles.
- Collect the Scroll Origins NFT
Scroll Origins is an NFT mint launched by Scroll to celebrate their earliest builders. To be eligible, you must deploy a smart contract to Scroll Mainnet within 60 days of 10th October 2023 at 6:00am GMT. Then, you will be eligible for 1 of 3 NFTs based on the deployment date (before 9th and 24th November, and 9th December 2023 respectively). Your NFT will be a better rank if you deploy earlier! The Scroll Origins NFT can be claimed on the Scroll website from 15th December 2023 onwards.
To deploy a smart contract to the Scroll Mainnet and be eligible for the Scroll Origins NFT, you must first bridge funds from Ethereum Mainnet to Scroll mainnet here (this is for gas fees when deploying the smart contract). Then, create your own token by going here and selecting the “ERC-20” tab. Choose a name and ticker symbol for your token. Under “Features”, select “Mintable” and at “Access Control” select “Ownable”. Then, click “Open in Remix” on the upper right-hand corner. On the new window, click on “Solidity Compiler” (the two arrows button on the left sidebar) and see if there is a green tick next to it. Afterwards, click the blue “Compile contract” button and the “Deploy and run transactions” button (this is the button showing the Ethereum logo with an arrow). Under “Environment” click on the drop-down menu and select” Injected provider-MetaMask”. Your MetaMask wallet will then pop up, log in and make sure you are on the Scroll Mainnet. Back on the webpage, paste your wallet address next to the “Deploy” button and click. Confirm the transaction when prompted to on MetaMask.
To check you have correctly deployed the smart contract, go to https://scroll.io/developer-nft/check-eligibility and check your eligibility for the NFT. If you are eligible, you will be told so and asked to come back on 15th December 2023 to claim it.
Here are the 3 Scroll Origin NFTs you can expect to get based on the smart contract deployment date: (1) Quintic: Before 9th November; (2) Quartic: Before 24th November; and (3) Cubic: Before 9th December.
Airdrop Review
When reviewing an airdrop, there are several factors to consider. First, the likelihood the project will even do an airdrop in the first place. Then, to look at how many tokens the project intends to allocate towards airdrop campaigns, as well as the difficulty in participating in their airdrop. It is also important to look at the utility of the token so that there will be an actual use and purpose in participating in the airdrop in the first place. Finally, a factor to consider when reviewing an airdrop is whether the airdropped tokens are subject to any lockup period.
Likelihood of Airdrop: Scroll has hinted they will create an “incentive network” to encourage participation on Scroll. The mainnet launch is confirmed to be in August 2023 so there is a good chance the airdrop might be then!fe
Airdropped Token Allocation: Scroll has not given any information on its token yet.
Airdrop Difficulty: Scroll has not yet released details about its airdrop. However, they are currently in the pre-alpha stage so it might be worthwhile to interact with the testnet to be eligible for any potential airdrop.
Token Utility: Scroll has not given any information on its token yet.
Token Lockup: Scroll has not given any information on its token yet.
