Bridge Kit now supports @arc Testnet!
Bridge Kit makes it easy to build crosschain experiences with @USDC and CCTP V2 in under ten lines of code:
→ Intuitive SDK methods
→ Built-in monetization support
→ Flexible setup
→ Step-by-step tutorials
Get started with Bridge Kit:
CCTP now supports upfront fee payment for Fast Transfers.
Builders can quote and collect Fast Transfer and Forwarding fees upfront, instead of deducting them from transferred USDC.
That means:
→ Users receive the expected USDC amount
→ Developers present one bundled quote
→
CCTP now supports more than USDC, extending Circle’s crosschain trust layer to native EURC transfers.
One integration, more capabilities for developers to enable seamless multi-asset experiences.

CCTP now supports upfront fees.
In this Release Notes episode, HJ walks through how builders can keep destination amounts exact when using Fast Transfer, CCTP Forwarding Service, or both.
Request a signed quote, pay the fee separately on the source chain, and let the recipient
AI agents need more than payment execution.
They need wallets, policies, spend limits, and clear rules for what they can do.
Circle Agent Stack gives builders the primitives for bounded autonomy:
→ Agent Wallets
→ Policy controls
→ USDC payments
→ Marketplace access
→ x402
