Ecosystem Showcase & Launches

 for a while now, and I'm excited to share what I've put together: 

 , a full cross-chain USDC bridge built specifically for the Arc ecosystem using Circle CCTP and Bridge Kit. 

Read below to learn and understand more about 

OFA Bridge is a Dapp that lets users transfer USDC natively across blockchains without liquidity pools. Instead of wrapping or swapping, it uses Circle's burn-and-mint mechanism. USDC is burned on the source chain and minted fresh on the destination chain. No slippage from liquidity depth, no wrapped tokens, just native USDC.

the bridge tab is the core of the app, powered by 

uses Circle Forwarding Service (via cctp) to automatically mint on the destination chain, removing the need for users to hold gas tokens there.

the user signs the mint themselves on the destination chain, once the attestation is ready.

A dedicated feature that allows users to bridge their assets directly to a different wallet address on the destination chain.

A specialized modal that lets users resume any stalled or interrupted CCTP transaction by providing the source chain 

. It automatically fetches the required attestations from Circle's APIs.

Integrated controls to protect users from asset price volatility during the bridging process (mainly for swapping Eth to receive USDC on Eth Sepolia, before bridging the USDC to the destination chain).

the swap tab lets users to swap assets like EURC to USDC, before switching to the Bridge tab to move USDC cross chain, all within a single interface. Includes real-time quoting and accurate fee calculation.

A Full transaction history and real-time status tracking. Built with 

, an open-source SDK I also built and published separately that tags every transaction to a unique Bridge ID. This lets the app track every step of the CCTP lifecycle (Approve → Burn → Attestation → Mint) and show users exactly where their transaction is at any point. It also separates OFA Bridge's traffic from global CCTP data.

 Ethereum Sepolia, Base Sepolia, Arbitrum Sepolia, Arc testnet and more.

That is All About OFA bridge for now, as I will post a demo on how the Retry tool and bridge-id-sdk works in the bridge, along with other features.

Thanks for reading till the end. I will be happy to receive your feedback about OFA Bridge.
