The blockchain ecosystem has exploded in recent years, with dozens of new networks emerging—many inspired by Ethereum’s architecture. These platforms often replicate Ethereum’s codebase while introducing variations such as lower transaction fees, alternative governance models, or unique consensus mechanisms. This widespread adoption of Ethereum’s foundational structure has led to what is known as the Ethereum Virtual Machine (EVM) model.
Under this model, developers can easily deploy smart contracts across multiple chains using familiar tools and standards. However, not all blockchains follow this blueprint. Non-EVM platforms like Solana, NEAR, and Cosmos have built their own infrastructure from the ground up. Even Bitcoin, though not a smart contract platform, operates independently of the EVM framework.
What Are Smart Contracts and Why Do They Matter?
A smart contract platform enables developers to deploy self-executing code on a blockchain. These contracts automate actions—like transferring funds, managing digital assets, or enforcing agreements—without intermediaries. For example, a simple smart contract might accept a deposit and split it between two parties. More complex implementations power decentralized finance (DeFi) applications such as lending protocols, yield farms, and liquidity pools.
Even popular tokens like USDC are themselves smart contracts. One major benefit of expanding blockchain options is increased accessibility to diverse DeFi services. Ethereum, despite its dominance, has long struggled with high gas fees—sometimes exceeding several dollars per transaction. In contrast, newer chains offer near-instant transactions for less than a penny, making DeFi more inclusive.

The Hidden Cost of Blockchain Proliferation
While multiple blockchains increase access to decentralized applications, they also create fragmentation. Assets native to one chain—like USDC on Ethereum—are not automatically available on others like Avalanche or Fantom. This limitation undermines the ideal of open, borderless finance.
Enter blockchain bridges.
Bridges enable cross-chain asset transfers, allowing users to move tokens from one network to another. They are essential for interoperability and composability—key pillars of a functional multi-chain ecosystem. Thanks to bridges, USDC has become the most widely used stablecoin across chains, available on EVM-compatible networks like Polygon and Binance Smart Chain, as well as non-EVM ones like Solana and Terra.
But despite their utility, bridges have a critical flaw: they are prime targets for hackers.
Why Blockchain Bridges Are So Vulnerable
In the past year alone, blockchain bridges have accounted for the majority of stolen funds in the crypto space. Major attacks include:
- Ronin Bridge (Axie Infinity): $625 million lost
- Wormhole Bridge: $300 million drained
- Harmony Horizon Bridge: $100 million compromised
- Nomad Bridge: Nearly $200 million stolen in a single week
These breaches highlight a systemic risk: bridges concentrate vast amounts of value in centralized smart contracts that, once exploited, can collapse entire ecosystems.
How Do Bridges Actually Work?
Many users assume that when they "bridge" USDC from Ethereum to Fantom, they receive the same token on the destination chain. But that’s not what happens.
True cross-chain movement of tokens is technically impossible between isolated blockchains. Instead, most bridges issue wrapped or synthetic versions of the original asset. For example, when you bridge USDC to Fantom via a hypothetical "Bad Bridge," you don’t get real USDC—you get badUSDC, a bridge-specific token pegged 1:1 to USDC.
You can use badUSDC on Fantom just like regular USDC. DeFi platforms often list it simply as “USDC,” creating the illusion of authenticity. The system works—until the bridge is hacked.
If attackers drain the Ethereum-side reserves backing badUSDC, the peg collapses. Suddenly, every badUSDC holder on Fantom owns a worthless token. Even if you never touched the bridge directly—holding only badUSDC in a wallet or liquidity pool—you suffer total loss.
This centralized dependency makes bridges a single point of failure. A successful hack doesn’t just affect one user—it can destabilize entire chains.
The Internet Computer: A Bridgeless Future
So what’s the solution? Avoid bridges altogether.
The Internet Computer (IC) introduces a revolutionary approach: direct integration with native blockchains like Ethereum and Bitcoin—without relying on intermediaries or wrapped assets.
When you send ETH from your Internet Computer wallet, you’re not using bridged ETH. You’re interacting directly with the Ethereum network. Your ETH remains on Ethereum at all times, secured by its native consensus mechanism.
This means:
- No centralized custody
- No risk of bridge exploits
- Full security of the original chain preserved
The same applies to Bitcoin. Users can trade or lend BTC on IC-based DeFi platforms without ever moving their coins off the Bitcoin network. Transactions are executed natively, eliminating reliance on vulnerable third-party bridges.

FAQ: Understanding Bridge Risks and IC Solutions
Q: Are all blockchain bridges unsafe?
A: Not all bridges are compromised, and many employ strong security practices. However, due to their design—holding large pools of assets—they remain attractive targets. Even well-audited bridges can fall victim to sophisticated exploits.
Q: Is wrapped USDC the same as real USDC?
A: No. Wrapped USDC is an IOU issued by a bridge, redeemable only if the bridge maintains sufficient reserves. If those reserves are stolen or mismanaged, the wrapped token loses value.
Q: How does the Internet Computer interact with Ethereum without a bridge?
A: It uses advanced cryptographic protocols to securely communicate with Ethereum’s network directly. This allows IC wallets and dApps to trigger real Ethereum transactions without custodial intermediaries.
Q: Can I still use DeFi on other chains without bridges?
A: Not currently—at least not safely. Most cross-chain DeFi relies on bridged assets. The Internet Computer is pioneering a new standard where assets stay on their home chains while still being usable elsewhere.
Q: Does this mean my funds are safer on the Internet Computer?
A: Yes. By removing bridges, the IC eliminates one of the largest systemic risks in crypto today. Your assets remain under your control and secured by their native networks.
Q: Will more blockchains adopt this bridgeless model?
A: While technically challenging, the success of IC’s architecture may inspire future innovations in cross-chain communication that prioritize decentralization and security over convenience.
Conclusion: Rethinking Interoperability
Most blockchains—from Avalanche to Solana—rely on bridges to access key assets like USDC. While these systems function well under normal conditions, they carry inherent risks. A single exploit can wipe out millions in user funds and erode trust across ecosystems.
The Internet Computer offers a fundamentally different path: bridgeless interoperability. By enabling direct interaction with Ethereum and Bitcoin at the protocol level, it preserves asset integrity while unlocking cross-chain utility.
This isn’t just an incremental improvement—it’s a paradigm shift toward a safer, more sustainable decentralized future.
