Learn how to bridge USDC to Arc via CCTP with Bridge Kit

Tim Baker

Crosschain UX usually fails for a boring reason: too much custom infrastructure. Different chains, different assumptions, and a transfer lifecycle that is painful to model correctly.

Arc’s “Bridge USDC to Arc” quickstart is designed to remove that friction. It shows how to move USDC from an EVM chain (for example, Ethereum Sepolia) or Solana Devnet to Arc Testnet using Circle’s Bridge Kit, powered by CCTP.

A quick mental model:

CCTP is a permissionless onchain utility for native USDC transfers. It burns USDC on the source chain and mints USDC on the destination chain. Bridge Kit wraps the workflow into a higher-level SDK so you can trigger transfers programmatically and listen to transfer lifecycle events in code.

What you will do in the tutorial:

Set up a small TypeScript project

Use Bridge Kit + the Circle Wallets adapter

Initiate a USDC transfer into Arc Testnet using Circle Dev-Controlled Wallets

Observe lifecycle events and verify the result onchain

Why this matters for builders:

It gives you a clean, event-driven baseline for crosschain deposits and funding flows

It avoids designing your own bridge state machine from scratch

It is directly reusable for wallet onboarding and app funding experiences
