Build apps with one USDC balance across chains.
What it does
Integrates unified USDC balances and crosschain transfers into applications using wallet- and network-specific implementation references.
When to use it
Use when applications need chain-agnostic balances, low-latency transfers, or pooled capital across chains.
How to use it
Give it a Gateway integration request for your project; it adapts the reference matching the wallet model and source and destination networks.
