The Risks of Bridged Stablecoins: What Every User Needs to Know

As a newly launched blockchain, PulseChain has to derive a large part of its liquidity from other blockchains through bridges. As a result, the network is mostly fueled by such Ethereum-based stablecoins as USDC, USDT, and DAI.

The popularity of these assets is hard to ignore. Yet, such an approach comes with some serious risks. The bridges may fail while centralized stable assets may blocklist USDL-related addresses at any time.

Why do these risks matter and what does Liquid Loans do to avoid them? Read on to find out.

What is a DeFi Bridge?

DeFi bridges represent software protocols serving to transfer digital assets across different blockchains.

Every blockchain operates as a closed system. Ethereum cannot natively send assets to Solana, and PulseChain cannot natively receive USDC from Ethereum. Bridges fill that gap by locking assets on one chain and creating their wrapped versions on another one. Thus, they facilitate the transfer of value and solve the interoperability problem.

Why Are Bridges Risky?

Despite their convenience, DeFi bridges are among the most exploited targets in crypto. Research tracking bridge losses from 2021 through 2023 puts the total above $2 billion stolen, and the Federal Reserve’s April 2026 stability analysis confirmed that bridge-related cascade risks remain a live concern for the broader financial system.

The risk profile depends on which type of bridge you use.

Trusted bridges are controlled by centralized units. They require users to trust a central operator, which reintroduces counterparty risk into a system designed to eliminate it. When that central point fails, whether through a hack, social engineering, or insider compromise, the losses are typically total.

Trustless bridges replace the operator with smart contracts and algorithms. Users connect through non-custodial wallets and remain in full control of their assets. But the code itself becomes the attack surface. Bugs discovered after deployment can be exploited within hours, and no amount of decentralization prevents a vulnerability in the underlying contract from draining funds.

Both models have failed at scale. The five hacks below account for the bulk of documented bridge losses.

The Largest Bridge Failures

• Ronin, $624 million (trusted bridge). Hackers gained control over five of the nine validator nodes controlled by a single entity through social engineering.
• Binance Bridge, $570 million (trusted bridge). An attacker exploited a bug found in BSC’s centralized proof verification system.
• Wormhole, $326 million (trustless bridge). A newly released protocol version contained a bug that an attacker discovered and exploited just a couple of hours after the commit.
• Nomad, $190 million (trustless bridge). An upgrade to Nomad’s contracts introduced a vulnerability that enabled hackers to bypass the message verification process and drain funds from the bridge contract.
• Harmony, $100 million (trusted bridge). The attackers compromised two of the four private keys that the project used for validating transitions.

Third-party audits and ongoing security reviews reduce the risk on the trustless side, but no single measure has proven sufficient on either model. The pattern across all five hacks is the same: a single point of failure, whether a validator key set or a contract upgrade, was enough.

Bridge Architecture Risk Comparison

Not every bridge carries the same risk profile. The architecture determines where funds can be lost, how easily an attacker can exploit the system, and what happens to your stablecoin on the destination chain.

👉 Quick takeaway: Trusted bridges are the fastest but most vulnerable to operator compromise. Trustless bridges shift risk to smart contract code quality. Lock-and-mint bridges introduce wrapped token and issuer censorship risk. Native issuance carries the least bridge risk but the most issuer dependency.

For PulseChain users holding USDC or USDT via a bridge, the lock-and-mint model means you hold a derivative of the original token. If the bridge is exploited or the issuer blacklists the bridge’s custody address, your wrapped stablecoin can lose its peg instantly.

The Risk That Goes Beyond the Hack: Settlement, Contagion, and Reserve Failure

Most coverage of bridged stablecoin risk focuses on the headline hack. That is only one of three failure modes that matter.

Settlement risk occurs when a bridge processes a transfer but the destination chain does not finalize the transaction. The user holds a token that the source chain considers transferred but the destination chain has not confirmed. In volatile markets, this window can last minutes and cost real money.

Contagion risk is less visible but potentially larger. The Federal Reserve’s April 2026 stability notes flag that multiple DeFi protocols often share the same bridge infrastructure. One bridge failure can freeze liquidity across every protocol that depends on it. The stablecoin market reached $317 billion in April 2026, growing more than 50% since early 2025. At that scale, a single systemic bridge failure is no longer a contained event.

Reserve and redemption risk applies specifically to bridged fiat-backed stablecoins. When you hold a wrapped USDC on PulseChain, you do not hold USDC. You hold a claim on a bridge contract that holds USDC. The MIT Digital Currency Initiative’s February 2026 research on the hidden plumbing of stablecoins found that this layered dependency creates exposure that reserve audits of the original issuer do not capture. The bridge operator’s solvency, access controls, and governance matter as much as Circle’s reserves.

These three risks compound each other. A governance failure at a bridge operator can trigger a settlement delay that cascades into a liquidity freeze across multiple protocols simultaneously.

What Regulators Are Doing About It

The regulatory picture has shifted fast. Here is where the major jurisdictions stand.

United States: The GENIUS Act has moved stablecoin governance from an open question to an active legislative priority. The Federal Reserve’s April 2026 analysis treats stablecoins as a systemic financial stability concern, not a niche crypto product. Reserve requirements, disclosure standards, and accountability for bridge operators are all part of the current policy conversation.

United Kingdom: In June 2026, the Bank of England published its policy statement and draft rules for systemic stablecoins. The BoE and FCA released a joint regulation framework the same month, covering reserve standards, redemption rights, and supervisory expectations for large-scale issuers. Bridging infrastructure is explicitly within scope.

European Union: MiCA is live, but global stablecoin issuers have created friction in implementation. Spain’s central bank warned in May 2026 that global stablecoins amplify systemic risk. The EU framework is still resolving how cross-border bridge activity fits within national supervisory boundaries.

The direction across all three jurisdictions is the same: tighter reserve standards, mandatory redemption guarantees, and clearer operator accountability. For PulseChain users, this matters because the stablecoins crossing into PulseChain via bridges (USDC, USDT) are issued by entities that will face these requirements. How they respond will directly affect what you can redeem and when.

Is PulseChain at Risk?

As mentioned earlier, a significant part of PulseChain’s liquidity comes from fiat-backed stablecoins that are risky by definition.

At the same time, third-party bridges that help to convert these assets into PLS impose additional danger, regardless of whether they are trusted or not.

How to deal with such a situation?

To create a truly trustless and secure platform, a number of methods come forward to solve it.

How to Assess a Bridge Before You Use It: A Practical Checklist

Not all bridges are equally dangerous. Before moving stablecoins onto PulseChain or any other chain, run through these five checks.

1. Who controls the validator set? Trusted bridges with fewer than seven independent validators have a single point of failure. Ronin lost $624 million when attackers controlled five of nine nodes held by one entity.
2. Has the bridge been audited in the last 12 months? Wormhole’s $326 million loss came from a bug in a newly released version. A recent audit by a named, reputable firm is a minimum bar, not a guarantee.
3. Is the bridge’s total value locked publicly visible? Bridges with opaque TVL give no early warning of a bank-run scenario. Use DefiLlama to check current TVL and historical outflows.
4. What happens to your token if the bridge is exploited? With lock-and-mint bridges, a successful exploit can leave your wrapped token worthless even if the underlying stablecoin is fine. Understand what you actually hold.
5. Does the issuer have a blacklist function? USDC and USDT both allow Circle and Tether to freeze specific addresses. If the bridge’s custody address is blacklisted, every wrapped token it backs becomes unredeemable.

Running this checklist takes under ten minutes. The five hacks above took seconds to execute.

How Does PulseChain Address The Risks of Bridged Stablecoins?

It’s hard to invent a tool that would bypass all the existing limitations in a single blow. Yet, the more layers you add, the higher the security. 

Thus, PulseChain relies on many different solutions and constantly looks out for more to add:

Decentralized stablecoins

Slowly but surely, PulseChain decreases its dependence on fiat-backed stable assets changing them for truly decentralized coins such as USDL.

USDL is PulseChain’s native stablecoin, backed by PLS collateral rather than fiat reserves held by a centralized issuer. It is governance-free and designed to be redeemable for $1 worth of PLS. Because it never crosses a bridge, it carries none of the wrapped-token derivative risk that USDC or USDT bring onto the chain.

That does not make it risk-free. It introduces a different tradeoff: exposure to PLS price volatility rather than bridge operator or issuer risk. For users who want to stay inside the PulseChain ecosystem without touching centralized stablecoins, USDL is the direct alternative.

Decentralized on and off-ramps.

Converting fiat into crypto always comes with a counterparty risk. Yet, some solutions help to bring the danger to a minimum.

For example, Coast has developed a non-custodial on-ramp tool specifically for PulseChain. It helps users to buy crypto directly from their bank accounts. But unlike CEXes, it transfers crypto directly to end-users’ wallets and thus minimizes the time when the funds stay at risk.

A variety of listings on exchanges

When a project lists its asset just on one of two CEXes, it puts its users in danger since these exchanges may ban the project at any time.

Increasing the number of listings can significantly reduce this risk. Even if a local government bans any of these platforms or the platforms themselves put a veto on the project, there will still be some workarounds available in other regions.

Mitigation Comparison: How These Approaches Stack Up

👉 Quick takeaway: USDL eliminates the issuer censorship and wrapped-token risks inherent to bridged stablecoins but introduces PLS price exposure. Coast reduces CEX counterparty risk at the fiat on-ramp stage. Multiple exchange listings provide exit redundancy but do not address on-chain bridge security.

No single mitigation eliminates all risk. USDL removes bridge risk but adds collateral volatility. Multiple listings provide exit options but do nothing if a bridge is exploited before you can exit.

The Risk Is Real. So Is the Path Forward.

No bridge is zero-risk. No stablecoin is perfectly safe. That has always been true, and the $2 billion-plus lost to bridge exploits from 2021 to 2023 makes it concrete.

What has changed in 2026 is the regulatory and institutional response. The Federal Reserve, the Bank of England, and the EU are all treating bridged stablecoin risk as a systemic financial concern. That scrutiny will push issuers toward stronger reserves, clearer redemption rights, and more accountable bridge operators.

For PulseChain users, the practical takeaway is simple. Know what you hold. Bridged USDC is not USDC. It is a claim on a bridge contract. USDL avoids that layer entirely, at the cost of PLS price exposure. Neither is automatically better. The right choice depends on your risk tolerance and your time horizon.

Frequently Asked Questions

What is the difference between a bridged stablecoin and a native stablecoin?

A bridged stablecoin is a wrapped representation of a token issued on another chain. You hold a derivative backed by a bridge contract, not the original token. A native stablecoin like USDL is issued directly on PulseChain and requires no bridge.

Can a single bridge failure affect multiple DeFi protocols at once?

Yes. The Federal Reserve’s April 2026 stability analysis found that multiple DeFi protocols often share the same bridge infrastructure. One failure can freeze liquidity across every protocol that depends on it.

Are bridged stablecoins regulated?

Regulation is moving fast. The U.S. GENIUS Act, the EU’s MiCA framework, and the Bank of England’s June 2026 joint rules with the FCA all address stablecoin issuers. Bridge operators specifically are within scope of the BoE/FCA framework. Requirements vary by jurisdiction and are still being finalized.

How do I know if my stablecoin is bridged?

Check the token contract on a block explorer. Bridged tokens typically carry a suffix like ‘.e’ (Avalanche), ‘W’ (wrapped), or show a bridge contract as the minter. On PulseChain, USDC and USDT held via the PulseChain bridge are bridged tokens.
