ContraflowBuilt on Circle and Arc
Contraflow runs on Arc and Circle's infrastructure.
In the app
Arc
Invoices, settlements and netting certificates are all recorded on Arc, with gas paid in native USDC.
Docs →Arc Explorer
Every transaction can be checked independently here, and the protocol stats are counted from the contracts' events on it.
Sourcify
The source of every Contraflow contract is published and verified against the deployed bytecode.
Docs →From Circle
Swap Kit
Shows a live USDC to EURC quote for any balance a loop leaves behind. Quote only: it never places a trade.
Docs →Unified Balance / Gateway
Lets you bring USDC from another chain to your own address on Arc, from your own wallet, to cover a balance a loop leaves behind.
Docs →Developer-Controlled Wallets
Lets Contraflow's own operator wallet sign its transactions through Circle's wallet infrastructure.
Docs →API
Offchain obligations can be recorded through the API. Contraflow never signs for tenants: parties grant scoped permissions, and tenants submit the signatures those parties made.
