Future Outlook:
Advances like Circle’s Cross-Chain Transfer Protocol (CCTP) simplify transfers and reduce risks. Improved security measures, regulatory clarity, and user-friendly platforms are accelerating adoption.
Key takeaway: Cross-chain stablecoin transactions are transforming digital payments, but users must prioritize secure platforms and stay informed about evolving protocols.
Stablecoins: Types, Roles, and How They Work
To understand how cross-chain transactions function, it's important to grasp the different types of stablecoins and their roles in the broader crypto ecosystem. Each type employs a specific mechanism to maintain stability, offering distinct advantages and challenges for cross-chain applications.
Types of Stablecoins
Stablecoins are categorized based on how they maintain their value, each designed to fulfill specific needs in the digital economy.
Fiat-Backed Stablecoins are pegged to traditional currencies like the U.S. dollar. These tokens are backed 1:1 by reserves held by independent custodians, with regular audits ensuring transparency. Tether (USDT), the fourth-largest cryptocurrency by market cap, is a prominent example, valued at over $167 billion as of August 2025. Its reserves include U.S. dollars, secured loans, and other investments. Similarly, USD Coin (USDC) uses a cautious approach, backing its tokens with high-quality U.S. Treasuries and cash deposits held within the U.S. banking system.
Crypto-Collateralized Stablecoins use other cryptocurrencies as collateral. Due to the volatility of crypto assets, these stablecoins require over-collateralization to ensure stability. MakerDAO's Dai (DAI) is a prime example, backed by assets such as Ethereum at about 155% of the circulating DAI as of December 2023. This decentralized system operates independently of traditional banks, with users locking assets in smart contracts to mint DAI.
Commodity-Backed Stablecoins tie their value to physical assets like gold. For instance, Tether Gold (XAUt) represents one fine troy ounce of gold stored in Switzerland, while PAX Gold (PAXG), regulated by the New York Department of Financial Services, follows a similar model.
Algorithmic Stablecoins rely on smart contracts and algorithms rather than collateral. These systems automatically adjust supply to match demand and maintain price stability. However, this category has faced setbacks, such as the collapse of TerraUSD (UST) in May 2022, which led to over $40 billion in investor losses when its mechanism failed.
Rating agencies have also weighed in on the risks associated with stablecoins. In its December 2023 report, S&P Global rated USD Coin, Gemini Dollar, and Pax Dollar as "Strong", while Dai, First Digital USD, and Tether were assessed as "Constrained." Frax and TrueUSD received "Weak" ratings.
Roles Stablecoins Play in the Market
Stablecoins are essential in the cryptocurrency landscape, primarily because they address the volatility of other digital assets. Their main role is to provide price stability, which is critical in a market prone to rapid fluctuations.
As trading pairs, stablecoins are indispensable. Over 80% of trade volume on major centralized exchanges involves stablecoins. Tether alone accounts for half of all Bitcoin and Ether trades and made up approximately 65% of trading activity on crypto platforms in March 2022. In the decentralized finance (DeFi) space, stablecoins are just as vital, contributing around 45% of liquidity in decentralized exchanges as of May 2022.
"Stablecoins are a digital, on-chain form of fiat money. They are easy to self-custody and transact, and they are also fast, particularly in the context of cross-border money movement. One could even consider them a better form than fiat, as they can move quicker and less expensively across existing financial infrastructure in certain circumstances."
– Kenneth Worthington, Brokers, Asset Managers and Exchanges equity analyst, J.P. Morgan
Stablecoins also play a growing role in cross-border payments. By Q1 2025, they accounted for 3% of the $200 trillion global cross-border payment market. For example, using stablecoins to send a $200 remittance from Sub-Saharan Africa is about 60% cheaper than traditional methods.
In regions with economic instability or high inflation, stablecoins offer a reliable store of value, helping people preserve purchasing power. They also serve as a bridge between traditional finance and the crypto world, enabling seamless transitions between fiat and digital assets without constant conversions.
How Stablecoins Are Issued
The issuance process is key to understanding how stablecoins maintain their value and operate across blockchain networks. Each type has its own approach to issuance, which ensures stability and interoperability.
Centralized Issuance is the standard for fiat-backed stablecoins. When users deposit fiat currency, the issuer mints an equivalent amount of stablecoins and transfers them to the user’s wallet. For example, Circle and Tether manage reserves in segregated accounts, ensuring they are legally separate from corporate funds.
Multi-Chain Deployment has become common for major stablecoins. By June 2025, USDC was supported on 23 blockchain networks. Despite being spread across multiple chains, the tokens maintain identical claims to the underlying reserves.
Cross-Chain Transfer Protocol (CCTP) is a newer development that facilitates stablecoin movement across blockchains. Circle’s CCTP uses a mint-and-burn process: stablecoins are burned on the source chain and minted on the destination chain, keeping the total supply constant and the peg intact.
Smart Contract Issuance powers crypto-collateralized stablecoins. Users deposit crypto assets into smart contracts, which then mint stablecoins. These contracts continuously monitor collateral levels, triggering automatic liquidations or requiring additional collateral if the value drops below set thresholds. MakerDAO, a leader in this field, even allocated $500 million to U.S. Treasury bills and opened a $100 million credit line with Huntingdon Valley Bank in 2022.
Algorithmic Issuance depends entirely on smart contracts to adjust supply based on market conditions. If the price rises above the peg, new tokens are minted; if it falls below, tokens are burned to restore balance.
These issuance methods form the backbone of stablecoin operations, ensuring they remain functional and interoperable across blockchain networks.
Understanding Cross-Chain Interoperability
Cross-chain interoperability allows stablecoins to move seamlessly between different blockchain networks. While each blockchain functions independently, interoperability creates secure and efficient pathways for transferring assets across these networks.
Technical Workflow of Cross-Chain Transactions
Transferring stablecoins between blockchains involves a four-step process: locking tokens on the source chain, validating the transaction, minting equivalent tokens on the destination chain, and releasing those tokens to the recipient.
Here’s how it works: first, stablecoins are locked in a smart contract on the source blockchain to prevent double-spending. Validators and oracles then confirm the transaction's finality. Once validated, the equivalent amount of stablecoins is minted on the destination blockchain, ensuring the overall supply remains unchanged. Finally, the newly minted tokens are sent to the recipient's wallet on the destination chain.
For instance, Circle's Cross-Chain Transfer Protocol (CCTP) uses a mint-and-burn mechanism across 56 routes on eight blockchains, processing $30 million in daily volume. Similarly, the Inter-Blockchain Communication (IBC) Protocol, built on Cosmos, supports 110 Layer 1 and Layer 2 chains, handling about $25 million in daily trading volume. It enables transfers between both EVM-compatible chains like Ethereum and non-EVM chains like Aptos.
This entire process depends on reliable infrastructure to ensure both security and efficiency.
Key Infrastructure Components
The success of cross-chain transactions relies on several critical components:
- Bridges: These act as intermediaries for moving assets between blockchains. Some bridges are trust-based, while others are trustless, relying on smart contracts.
- Validators and Oracles: Validators verify transactions, while oracles supply external data to ensure tokens are securely locked before minting. However, centralization risks remain significant. Chainalysis estimates that over 40% of successful attacks on cross-chain solutions target centralized components like oracles and relay networks.
- Relayers: Relayers handle the transmission of transaction data between networks.
- Smart Contracts: These automate the entire process - locking, validating, minting, and unlocking - without human intervention. However, vulnerabilities in smart contract code can lead to exploits, such as the Poly Network attack in August 2021, where hackers stole over $610 million by exploiting a flaw.
A newer approach to cross-chain infrastructure is the Canton Network, launched in May 2025 by Digital Asset in collaboration with Goldman Sachs, Deutsche Börse Group, and Microsoft. This privacy-focused network connects siloed financial systems while maintaining the controls required for heavily regulated industries.

Security remains a major concern. In 2022, attacks on bridges accounted for over $1 billion in losses - 69% of all stolen funds that year. The Wormhole Bridge hack in February 2022 highlighted how cross-chain infrastructure can attract malicious actors.
Despite these risks, the benefits of cross-chain interoperability are fueling its rapid adoption. Decentralized exchange trading volumes grew by over 800% in a single year, largely driven by cross-chain capabilities. By early 2025, stablecoin volumes used for remittances represented 3% of the $200 trillion global cross-border payment market.
"The ability to settle payments globally in a fast, secure, and cost-effective way is being transformed by the proliferation of tokenized cash using blockchain technology."
The regulatory landscape is also adapting. Key jurisdictions are introducing frameworks like the US GENIUS Act of 2025 to provide clearer guidelines for cross-chain operations. Meanwhile, financial giants are embracing tokenized cash - JPMorgan's JPM Coin, for example, now facilitates over $1 billion in daily transactions between institutional clients.
As the blockchain ecosystem evolves toward a multi-chain future, understanding these technical foundations and trade-offs is essential. Instead of competing, hundreds - or even thousands - of blockchains are likely to coexist, reshaping the digital economy.
