Circle Internet Financial has introduced the Bridged USDC Standard, a framework enabling Ethereum Virtual Machine (EVM) blockchain teams to deploy bridged USDC with the possibility of upgrading to native issuance later. This standard seeks to resolve the "cold start" problem by allowing new blockchains to leverage USDC liquidity without waiting for native issuance, thus facilitating early ecosystem activity. Bridged USDC, created by third parties, serves as a proxy to USDC, helping bootstrap liquidity and fostering new use cases. Unlike native USDC, bridged USDC can be quickly deployed on emerging blockchains, which are proliferating faster than Circle can issue native USDC. The Bridged USDC Standard allows for seamless transitions of ownership of bridged USDC token contracts to Circle, enabling a potential upgrade to native USDC while preserving existing user balances and integrations, thus minimizing liquidity fragmentation and the need for migrations. Implementations of this standard are already underway on platforms like Linea and Scroll, and Circle aims to expand this approach to other architectures and potentially extend it to other stablecoins like EURC.

Composability in smart contracts refers to the ability to combine elements from different contracts to create new, complex applications, akin to assembling Lego blocks. This concept is pivotal in the Web3 ecosystem, enabling innovations like decentralized games, NFTs, and DeFi platforms by allowing smart contracts to interact and build upon one another. The tutorial explores using composability with Circle's USDC, a stablecoin backed 1:1 by the US dollar and operating on the ERC-20 standard, which ensures interoperability on blockchains like Ethereum. By guiding users through creating a smart contract that interacts with the USDC contract to check wallet balances, the tutorial demonstrates composability in a practical context. This feature facilitates the development of decentralized applications by leveraging existing smart contracts, as illustrated by the example of Credix, which uses USDC and composable contracts for cross-border institutional lending. The document emphasizes that composability reduces the need for central intermediaries, enhancing the decentralized nature of blockchain applications.

Additionally, the upgrade eliminates blocklist checks in functions that don't move funds, further reducing gas fees, and introduces a one-time renaming of the EURC token symbol. This enhancement is part of Circle's ongoing efforts to innovate and expand USDC's capabilities, following its recent expansion to six new blockchain networks. The rollout is occurring in phases across multiple testnets and mainnets without requiring any actions from developers or users, and all code changes have been vetted by the security firm Halborn.

The research paper "Beyond Speculation: Payment Stablecoins for Real-time Gross Settlements," led by Circle Chief Economist Gordon Y. Liao, highlights a significant shift in the use of stablecoins from speculative trading in cryptocurrency markets to practical applications such as cross-border payments and remittances. Over the past five years, the use of stablecoins for speculative activities has decreased by 90%, indicating a transformation in their role in digital asset markets. Originally serving as blockchain-based cash for traders, stablecoins like USDC have evolved into general-purpose money tokenized on public blockchains, characterized by their full-reserve backing and primary use for payments rather than trading. The paper suggests that the integration of payment stablecoins into existing financial systems could enhance real-time settlement capabilities, making them more transparent and accessible, while also reducing risks associated with liquidity and concentration in current payment systems.
