In a significant move for the cryptocurrency world, Circle, the issuer of the USDC stablecoin, has extended its reach by launching on the Polkadot network. This development not only broadens the stablecoin’s native availability but also enhances interoperability among various blockchains.
A new home for USDC
Circle announced that it has issued a native version of USDC on the Polkadot Asset Hub, a system parachain designed for asset issuance within the Polkadot ecosystem. This allows the stablecoin to be transferred to other parachains via the Cross-Consensus Message (XCM) protocol. Consequently, all interconnected parachains and their users in the Polkadot ecosystem will now have access to USDC, which is redeemable 1:1 for U.S. dollars. Polkadot-based projects like Centrifuge, HydraDX, and Moonbeam have already begun offering USDC as their flagship stablecoin.
The growing footprint of USDC
USDC is the second-largest stablecoin by market capitalization, boasting an aggregated value of $26 billion. Before its Polkadot debut, the stablecoin was natively available on several other blockchains, including Ethereum, Solana, Arbitrum, Polygon PoS, Base, Optimism, and Tron. The Polkadot integration aims to maintain Circle’s position as a major interoperable cryptocurrency while also supporting low-cost payments. This addition enables trading, borrowing, and lending on Polkadot parachains like Centrifuge, HydraDX, and Moonbeam.
For users and developers, the Polkadot USDC is immediately accessible through Circle Account and Circle APIs. However, Circle emphasized that users must transfer USDC from their Circle Account to an external Polkadot Asset Hub wallet address before using the XCM protocol. Additionally, when transferring USDC to other parachains via XCM, users are advised to transfer the funds back to the Polkadot Asset Hub before depositing them into their Circle Account to avoid potential loss of funds.
Polkadot, launched in 2020, is a network of multiple independent blockchains, commonly referred to as parachains. These operate in parallel, allowing for faster transactions while benefiting from Polkadot’s overall security and decentralization. With the latest addition, USDC now supports a total of 14 various blockchain networks, surpassing its rival stablecoin, USDT, which supports 11 networks as of this writing.
The move comes at a time when the cryptocurrency market is increasingly focusing on interoperability and user-friendly platforms. Circle’s decision to expand USDC to the Polkadot ecosystem marks a significant step in this direction, offering users more options and flexibility in how they manage and transfer their digital assets.
