Kadena Chain Shuts Down: Why Did This “JPMorgan-Bred” Public Chain Reach Its End?
#Kadena #JPMorgan Once waving the banner of an “enterprise-grade PoW smart-contract platform” and founded by former JPMorgan blockchain team members, Kadena has now announced it is ceasing operations. Its native token KDA plunged more than 60% intraday, and ecosystem development has nearly ground to a halt. From a nearly $4B “star chain” to today’s exit announcement, Kadena is not just a case study in a project’s failure — it also reflects systemic risks and a turning point in the crypto infr...

#CrossChainBridge #SuperEx
In the crypto community, there’s a consensus: cross-chain bridges are both the most dangerous and the most indispensable infrastructure in the crypto world.
They are dangerous because most major on-chain exploits have targeted bridges. They are indispensable because bridges are the very interaction hubs of the crypto world.
Before cross-chain bridges existed, it was widely accepted that assets existed only on their native chain. For example:
BTC on Bitcoin
ETH on Ethereum
Applications, liquidity, and users were tightly bound to their respective ecosystems.
But as the multi-chain era truly began — with Layer 2s, sidechains, appchains, and modular chains developing in parallel — users faced a new reality: assets are on one chain, but the application is on another.
Thus, cross-chain bridges were born. They are both the “transportation systems” of the multi-chain world and — so far — one of its most attacked and most devastatingly vulnerable infrastructures.
To understand cross-chain bridges is to grapple with one fundamental question:Can blockchains really trust one another?
SuperEx Educational Series: The Cross-Chain Bridge - The Most Dangerous, Yet Most Indispensable…
In the crypto community, there's a consensus: cross-chain bridges are both the most dangerous and the most…news.superex.com

From the user’s perspective, a cross-chain bridge looks simple: move assets from Chain A to Chain B, and a few minutes later, see the equivalent on another chain.
But from a systems perspective, this is highly counterintuitive.
Because at the heart of blockchain is one foundational principle: each chain only trusts itself.
Ethereum won’t actively verify Solana
Bitcoin doesn’t read the state of Arbitrum
Blockchains don’t natively talk to one another
So cross-chain bridges don’t literally “move” assets, but instead simulate this movement through alternative mechanisms.
Most cross-chain bridges are essentially doing three things:
Locking or burning assets on the source chain
Minting a representative asset of equal value on the destination chain
Maintaining a system that upholds state consistency
Which leads to a fundamental fact: a cross-chain bridge can never be as secure as the native security of a single chain.
Despite the vast range of implementations, most bridges today fall into three broad categories:
This is the earliest and most common bridge model. The process is straightforward:
Users lock assets on Chain A
The bridge mints an equivalent wrapped asset on Chain B
The reverse process happens on withdrawal
Examples:
WBTC (BTC → Ethereum)
Most early EVM-based bridges
Pros:
Simple to implement
Clear liquidity management
Clear asset mapping
Fatal flaw:
All risk is concentrated in the locking contract
Once breached, the assets are almost always irrecoverable
Most of the largest bridge hacks in history occurred under this model.
To avoid lock-up risk, some projects take a different route: instead of minting new assets, they use existing liquidity to swap across chains.
For example, a user deposits funds on Chain A, and the bridge pays out from its liquidity pool on Chain B — akin to a cross-chain market-making system.
Pros:
No massive asset lock-up
Faster cross-chain speeds
User experience resembles a swap
Cons:
Highly dependent on liquidity depth
Slippage and pricing risk
High cost for large transfers
This model is more market-driven, but also more prone to volatility and liquidity fragmentation.
This is the most technically ideal — but also most complex — cross-chain design.
The core idea: allow one chain to directly verify the state of another chain using light clients or cryptographic proofs. For example:
Chain B verifies blocks or states from Chain A
No need for centralized relayers
Security is theoretically on par with native chains
Examples:
IBC (Cosmos)
Some ZK-based bridges
Next-gen modular cross-chain solutions
Challenges:
Extremely complex to implement
High cost
High demands on underlying chains
This model is not yet ready for mass adoption, but remains the long-term ideal.
Look back at the largest security breaches in crypto, and you’ll find one harsh truth: the biggest exploits almost always involve bridges.
Here’s why:
A bridge builds trust between systems that do not natively trust each other. This introduces:
More assumptions
More permissions
More attack surfaces
Any weak link can cause a systemic failure.
Compared to a single DeFi protocol, a bridge is the gateway to full-chain assets.One breach can yield hundreds of millions.High risk × high reward = perfect target for attackers.
Even in decentralized designs, there are still:
Observers
Relayers
Signing nodes
These off-chain parts are inherently weaker in terms of security guarantees.
Each of the following attack types has been exploited repeatedly, causing hundreds of millions in losses.
How it works:Many bridges use multisig to confirm messages like:“Lock 100 ETH → Mint 100 wrapped ETH.”If a hacker gains enough private keys, they can:
Forge a lock message
Mint unauthorized assets
Withdraw funds freely
Case: Ronin Bridge ($600M)
The attacker controlled 5 of 9 validator keys managed by Sky Mavis and forged withdrawals — the largest attack in crypto history.
Key risks:
Centralized control
Poor key storage
Lack of permission separation
Solutions:
Decentralized validation (PoS, light clients)
MPC key management
Decentralized multisig
Daily withdrawal caps
How it works:Some bridges verify “proofs” of events from other chains.
If the verification logic is flawed, attackers can forge those proofs.
Case: Wormhole hack ($320M)
The contract failed to check signature integrity.Attackers submitted a fake proof and minted 120k ETH on Solana.
Weak points:
Incomplete verification
No secondary signature checks
Lack of timestamps or chain IDs in messages
Solutions:
zk-SNARKs
Multi-layer proof verification
Dual confirmation
Replay protection
Occurs when external calls happen before internal state updates, allowing repeated withdrawals.
Solutions:
Use OpenZeppelin’s ReentrancyGuard
Adjust execution order: state update → fund transfer
Mark executed messages
Bridges relying on price oracles for minting/burn can be exploited if price feeds are manipulated.
Solutions:
Use TWAP
Aggregate multiple oracles
Avoid minting based on a single feed
Even if a proof is valid, reusing it on another chain can cause duplicate minting.
Solutions:
Use nonce
Embed chain ID
Ensure message uniqueness
If relayers are compromised, they can submit fake “locked” messages to the destination chain.
Solutions:
Multi-relayer consensus
zk-based light clients
Trustless relaying mechanisms
Bridges will get safer in the future — but not today.
Until then, your best protection is not technical knowledge, but knowing how to avoid common traps.
Bridges are not banks — they are top hacker targets.
Never bridge more than you can afford to lose.
Especially when:
Bridging between obscure chains
The project just launched
TVL < $50M
No audits
No reputable team
Any of these is a red flag.
Some of the safest options today include:
LayerZero
Wormhole 2.0
Cosmos IBC
Axelar
Chainlink CCIP
Not risk-free, but far safer than the average bridge.
For example:
Arbitrum Bridge
Optimism Bridge
zkSync Bridge
Polygon PoS Bridge
These are often natively integrated and more secure.
Don’t leave funds idle on the bridge.
Scammers airdrop tokens and lure you into connecting to fake bridges.
Bridging = Contract interaction = High risk.
If you see:
Sudden TVL drops
Unusual delays
Withdrawals stuck across chains
Stop everything immediately — these are signs a bridge is about to fail.
In a perfect world:
All chains would talk natively
Security would be inherited
No trust trade-offs required
But the multi-chain world is itself a compromise on the single-chain security model.And bridges are the very embodiment of that compromise.
They unlock liquidity, expand composability, and break ecosystem silos.But they also constantly remind us: every bridge transaction is a trade-off in trust.
To understand bridges is not to blindly trust them — but to understand exactly who you’re trusting.
