Fund Gateway Balances up to 40x Faster With Fast Deposit

‍

Crosschain products compete on the time between a user deciding to move money and being able to use it. Previously, funding a Circle Gateway balance on slower finality source chains could require waiting roughly 15 minutes before USDC became available. For wallets, trading apps, prediction markets, and other speed-sensitive products, waiting for transaction finality could interrupt onboarding, create user dropoff, and cede ground to competitors.

Gateway Fast Deposit changes the calculus by moving at the speeds builders need. Available through Unified Balance Kit, this new Fast Deposit capability helps developers fund a Gateway balance up to 40x faster on chains with longer times to finality.

Fund a Gateway balance up to 40x faster

Gateway Fast Deposit brings CCTP Fast Transfer into Unified Balance Kit. At launch, it supports USDC flows from 9 Fast Transfer source chains to Avalanche and Polygon as fast-finality destinations, with future support planned for Arc mainnet.

Developers retain the familiar Gateway workflow, with route-specific choices built into the Unified Balance Kit integration. To get started with Gateway Fast Deposit, developers:

1. Select Avalanche or Polygon as the destination chain.
2. Choose FAST transfer speed. 
3. Then Unified Balance Kit automatically coordinates the transfer and deposit steps and provides pre-execution fee estimation.

One integration, three practical benefits

First, Gateway Fast Deposit gives users a balance up to 40x faster, reducing transaction finality waits from roughly 15 minutes to seconds¹ on supported routes while source-chain finality completes in the background. Secondly, it streamlines integration into one developer workflow. Unified Balance Kit coordinates fee estimation, routing inputs, forwarding, and Gateway deposit execution. Third, you can operate on an integrated platform that supports use cases such as fast crosschain funding, unified USDC balances, and programmable transaction flows through one cohesive operational model.

Built for products where quick deposit access matters

Gateway Fast Deposit makes Gateway practical for wallets, trading apps, prediction markets, crosschain applications, and other experiences where funding speed can shape activation and conversion. Teams can offer a simpler and faster crosschain funding flow without building separate routing and execution infrastructure or maintaining individual balance workflows for every supported chain.

This launch shows the value of Circle’s integrated platform. By bringing crosschain tools into one developer experience, teams can reduce integration burden, lower implementation risk, and keep the path to production clear.

In tandem with Gateway’s support for ERC-1271 and programmable authorization, Gateway Fast Deposit gives Gateway the speed, flexibility, and programmability that developers need to build the next generation of financial products.

Start building with Gateway Fast Deposit

Standard Gateway deposits remain available for workflows that do not require accelerated funding. For supported routes and use cases where speed matters, Gateway Fast Deposit gives developers a speed-focused path to a usable and unified USDC balance quickly.
