TL;DR
Across now supports up to 10M USDC bridging using Circle’s CCTP v2, enabling native, canonical USDC transfers across supported chains. Built for users and developers moving serious capital, with integration available via the Across Swap API.
Introduction
Size doesn’t matter… until it does.
When you move whale-sized amounts of crypto between chains, you need a bridge you can trust. Across now supports up to 10M USDC transfers, powered by CCTPv2.
Here’s what you need to know.
The Bridge Built for All Sizes
Bridges shouldn’t discriminate against size.
You can now bridge up to 10M USDC in a single transfer with Across. This unlocks fast, cheap, and secure transfers for whales, treasuries, funds, market makers, and anyone moving serious capital across chains.
Keep in mind that these are truly canonical USDC transfers. No wrapped assets. No liquidity fragmentation. Your USDC burns on the source chain and mints natively on the destination chain.
Whether you are an everyday user or the equivalent of an onchain Moby Dick, you can move your money without compromising on speed, cost, or security.
How It Works
Across integrates Circle’s Cross-Chain Transfer Protocol v2 (CCTPv2) to enable native USDC bridging to any CCTP-enabled chain that Across supports.
CCTPv2 uses a burn-and-mint model, where USDC is burned on the source chain and the same exact amount is minted natively on the destination chain. The result is a clean, capital-efficient, and secure way to move USDC across chains, now extended to $10M transfers on Across.
Here’s the coolest part: Across automatically handles transaction finalization. Unlike most CCTP-based bridges that require you to return and sign a second transaction to complete the transfer, Across runs a custom finalizer that monitors your transaction and completes it for you. Once you initiate the transfer, you’re done. No need to come back and click anything else.
Note: CCTP transfers include a small protocol fee set by Circle (1bp from Arbitrum, and low-range bps from other chains), which is transparently reflected in the transfer before you execute it.
Swap API For Developers
The upgrade isn’t just for end-users. If you’re a developer, we’ve got you covered too.
Building an app with native stablecoin transfers? If so, you’re only one integration away from bringing $10M-capacity USDC bridging directly to your users.
With our Swap API, you can plug into Across and provide crosschain functionality within your native UI. Across runs “under the hood,” abstracting away the complexity so you don’t have to manage burn-and-mint logic, edge cases, or fragmented liquidity yourself. Your users get fast, reliable USDC bridging directly inside your product, while you stay focused on what you’re building.
USDC at Internet Scale
USDC has evolved into one of the most important pieces of onchain financial infrastructure.
Today, nearly $80 billion USDC is in circulation, making it one of the largest and most widely used digital dollars in the world. It is accessible on all the chains that people actually use, powering everything from trading and DeFi to payments and treasury operations.
As usage spreads across chains, the need to move large amounts of USDC reliably and natively becomes unavoidable.
