At the beginning of the month, @ParticleNtwrk released the first phase of the Co Alliance, one account, one balance, linking any chain. I’ve been using it for a month, and it really saves time and effort; it’s definitely a win-win situation.

This time, Particle has joined public chains such as Base, Linea, Taiko, Kakarot, Zircuit, etc. There are several key interactions to focus on.

The tutorial is as follows:

1. Let’s talk about the significance of the Co Alliance launched by Particle 1.1 Concept of Particle Co Alliance

The Co-Testnet Alliance launched by Particle is an industry-first initiative, consisting of over 60 public chains, including EVM, non-EVM, and BTC ecosystems, such as Arbitrum, Avalanche, Berachain, Botanix, BNB Chain, Linea…

Within this alliance, we only need one account and one balance to link all chains.

1. What is the significance of Particle's Co Alliance? (Example)

For example, in Web2, there are global financial systems like VISA, Apple Wallet, Paypal (which can be compared to UnionPay or Alipay in China), which can link all bank accounts and payment systems.

If they had their own digital currency, say "Apple Coin," transferring money into Apple Wallet would be equivalent to subscribing to an equal amount of Apple Coin. Users would only need to use Apple Wallet to navigate through various financial ecosystems, enjoying all the benefits within the financial ecosystem, achieving one account, one balance, linking all ecosystems.

2. What is the significance of Particle's Co Alliance? (Web3 Model)

Back to Web3, there are now hundreds of public chains, each with its own wallet, and GAS fees are mostly independent. Users need to learn various specialized knowledge to get started, which inadvertently raises the threshold for newcomers.

The concept proposed by Particle is similar to Apple Wallet, aiming to link all ecosystems through just one account and one balance.

Particle has already implemented "one account" and "one balance," and we have experienced the previous testnet. Now it’s time to "link all ecosystems." The significance of Particle's Co Alliance lies here: through technological means, gradually connecting EVM, non-EVM, and BTC ecosystems, achieving true "one account, one balance, linking all ecosystems."

In the example above, we mentioned that using Apple Wallet allows users to enjoy benefits from various institutions within the financial ecosystem. The same applies to Particle; if the partnered public chains have incentive activities, users interacting through Particle can also enjoy related benefits, such as those recently launched on Base, Linea, Kakarot, Zircuit.

2. Specific Interaction Tutorial

1. Basic Operations

· Register on the official website: https://pioneer.particle.network/?inviteCode=A58DD1…, invitation code: A58DD1

· Claim water

· Complete Task 2: Transfer ETH Sepolia to Particle Testnet

Please refer to previous tutorials for the above two steps (only complete Task 2, see the following for the remaining operations): https://link.medium.com/f5PkUidFGLb

2. Complete the Co-Testnet Phase Two Activity

This step corresponds to (Step Three) in the previous tutorial, but the Co-Testnet Phase Two activity requires interactions with public chains like Base, Linea, Taiko, Kakarot, Zircuit.

Interaction examples are as follows:

3. Complete Task Three on the Official Website

· Open AA wallet (copy address)

· Click Send

· Paste AA wallet address

· Select target chain, here choose (Base, Linea, Taiko, Kakarot, Zircuit)

· Enter transfer amount

· Confirm

It is important to note that when selecting ETH as the main chain, the transaction fees are relatively high. It is recommended to transfer a larger amount of ETH to other chains (like Base) first, and then use the Base chain to transfer between these chains.

4. Complete Task Four on the Official Website (Purchase NFT)

This task requires purchasing NFTs on different chains, with a limit of 5 interactions per day, and 50 interactions can earn a CO-TESTNET NFT.

· Scroll down the page to find Task Four

· Click PURCHASE NFT

· Select chain

· Click PURCHASE

· Choose the asset you want to pay with

· NEXT

· Confirm

It is important to note that purchasing NFTs on different chains does not require you to hold the relevant ETH on that chain; you can simply pay with USDG. For example, if you want to purchase an NFT on Linea, you do not need to transfer ETH to Linea. This embodies the principle of "one account, one balance, linking all ecosystems."

Each airdrop can be operated with multiple accounts. Currently, I am using the multi-account tool: MorLogin fingerprint browser, which has been tested for security.

The tutorial for multiple airdrop operations is as follows (with a one-month duration and 50 free environments): https://link.medium.com/ksIzjipHGLb
