Battlechain

Before mainnet, there's Battlechain.

The adversarial L2 for mainnet-bound protocols.

Whitehats.

It’s time the industry treated you right.

.@cyfrin has been working tirelessly to shift security left, into developers' hands, since day 1.

- Building tools like @SoloditOfficial, Aderyn, Moccasin
- Teaching people how to become auditors at @CyfrinUpdraft
- Doing conventional audits

And we just took another step

If you haven’t tried exploiting contracts on @battlechain yet:

Here’s a 90 seconds walkthrough using the starter repo, covering the full attack flow.

For this demo, my wallet is both exploiter and recovery.

Normally these are separate and the bounty split is visible.

Deploy and attack on battlechain testnet because:

1. It’ll give us feedback to make this security product better
2. You’ll learn deployment best practices (and teach your agents them)
3. We can run an IRL attackathon with Red Bull and weightlifting

[Battlechain @battlechain]

The instant your contract goes attackable - the bots come out.

The security agents are strong on the battlechain

[webrainsec @webrainsec]

TX says "Failed.", but the vault is empty.

2,000 tokens drained. Bounty settled.

We caught a live @battlechain target, decompiled raw bytecode, found a reentrancy, and exploited it. All autonomous. Zero human code.

Full breakdown below 🧵

@sanujitmajhi_07 It does not replace bug bounties.

I’m not sure I understand your second question. Could you perhaps rephrase it?

@developerjordy Interested.

[codemuggle @monatwt_]

The diff between 'it works' and 'it’s secure' is where most devs lose.
Battlechain is bridging that gap.

Seeing the @battlechain testnet go live is such a win for Web3 security. 🛡️

Huge congrats to @PatrickAlphaC and the @cyfrin team for building something this impactful. Happy to be spreading the word :)

The testnet is live, don't miss it.💙

[Battlechain @battlechain]

@0xandreitoma Good shout… we will update the QuickStart

[Battlechain @battlechain]

@bounty50657 YES!!!

[Battlechain @battlechain]

@Nuraa3754 @PatrickAlphaC @CyfrinUpdraft @CodeHawks We need these normalized

[Battlechain @battlechain]

@Lau_6669 Yes!!!
