Sure, memecoins are fun and BTC will soon again pass $100k, but what about the assets that are tied to reality and make up nearly 50% of each person’s crypto portfolio? Stablecoins. They play a crucial role as a form of global payment by providing a reliable and secure medium of exchange for cross-border transactions, enhancing financial inclusion worldwide. There’s a need for instant access and seamless transfers between stablecoins, and Squid is providing it.

Circle’s USDC is the second largest stablecoin to exist, with a $42.5b market cap as of December 18th, 2024. Circle released their Euro-pegged stablecoin, EURC, in 2022. And while EURC’s market cap is currently at $87m, there have been technical boundaries which have prevented users and developers from leveraging EURC in the same way that they have been able to with USDC.

Circle’s Cross-Chain Transfer Protocol (CCTP) enables USDC to flow securely between blockchains — unifying liquidity and simplifying user experience. However, CCTP only works this way for USDC, not for EURC, which has been a limiting factor when it comes to leveraging the Euro-pegged stablecoin. Enter Squid.

Squid’s intuitive architecture enables seamless access to EURC across Base, Ethereum, Avalanche, and Celo. Transferring EURC across chains with Squid is just as easy for users and developers alike as transferring USDC via CCTP. This novel ease of transferring USDC and EURC is made possible by Squid 2.0’s intelligent routing, which supports a number of highly efficient 1:1 cross-chain stablecoin and RWA transfers.

Users can swap EURC across multiple chains, or on the same chain, with app.squidrouter.com. Developers can seamlessly integrate the same cross-chain capabilities into their own projects, no matter the chain they’re building on, with Squid’s integration tools. We’ve provided a tour of Squid’s app, an integration guide in the sections below, and everything else you need to know.

Unlocking EURC <> USDC across chains

Squid taps into existing USDC and EURC liquidity to enable cross-chain swaps between them. For example, a USDC / EURC transfer might occur via Aerodrome on Base, or Uniswap on Base. When a developer chooses to integrate Squid into their own app, they unlock secure access to deep liquidity, efficient transfers, and strategic routing.

Circle has a thriving ecosystem of teams and projects building apps on CCTP. Leading wallets, bridges, apps, and protocols choose CCTP as a superior way to send, spend, lend, borrow, and transfer USDC across blockchains. Circle’s ecosystem extends to other services, including their Programmable Wallets and Smart Contract Platform.

Circle’s builders can leverage Squid to offer EURC to their users in a multi-chain fashion, further increasing the decentralized accessibility and global accessibility of the Euro-backed stablecoin. EURC enables payment connectivity and offers opportunities for euro-denominated financial services to reach more people in more places.

A quick tour of Squid’s app

Here are some unique features on Squid’s app that offer extra visibility when swapping USDC and EURC on app.squidrouter.com. Not only are swaps seamless, but you can preview routes before swapping, and watch in real-time as they’re executed and reach your wallet in only a matter of seconds.

Additionally, our recent feature Squid Wallet View offers you a complete view of all of your assets across chains, accounts, and wallets. Aggregated balances come in handy, allowing you to see each chain you have USDC on, without needing to switch back and forth between accounts.

Integration Guide

Squid makes it easy to integrate EURC into your app using the Squid widget. Out of the box, you can allow users to bridge any asset from over 80+ supported chains into EURC on the chain of your choice. There are three ways you can integrate Squid:

1. Widget
