Circle’s own public chain Arc early interactive teaching, 11 projects have been launched on the test network
It has been three weeks since Circle’s Layer 1 blockchain Arc launched its testnet. Users do not need to hold ETH or other volatile tokens to use USDC for on-chain operations. This article compiles 8 interactive steps to help you ambush potential ecological opportunities.
(Preliminary summary: Circle’s new blockchain Arc cooperates with Fireblocks: accelerating the settlement of banks and asset management companies, and the testnet will be launched in the autumn)

It has been three weeks since Circle’s Layer 1 blockchain Arc launched the testnet. Unlike many Layer 2s, Arc positions itself as an "economic operating system for the Internet." Its biggest advantage is that it uses USDC directly as gas fees, which means that users and institutions do not need to hold ETH or other volatile tokens to perform on-chain operations.
In addition, Arc is EVM compatible, provides configurable privacy options to support compliance requirements, and is directly integrated with Circle's full-stack platform for application scenarios such as lending, capital markets, foreign exchange, and payments.
More importantly, as an EVM-compatible chain built by stablecoin giant Circle, Arc has two core barriers: on the one hand, it relies on Circle’s accumulated TradFi resources, and on the other hand, it relies on USDC’s huge liquidity pool, which makes it very likely to become the core position for the implementation of RWA (real world assets) and enterprise-level applications in the future, occupying a first-mover advantage in the field of institutional blockchain applications.
Circle also revealed on the day of its Q3 financial report that it is currently exploring the possibility of launching native tokens on Arc. Arc is currently in the public testnet stage, which is a window period for users to experience early functions and lurk potential ecological opportunities. It needs to be reminded that testnet interactions are not necessarily accompanied by subsequent rewards. It is recommended that everyone participate with a normal mind of learning and experience, and treat airdrop opportunities rationally.
The following are 8 interactive steps compiled, covering operations such as basic configuration, contract deployment, token exchange, and NFT minting.

8. Register a domain name at InfinityName: img/datapic/fx/2025122918171486 The first batch of 11 projects constructed on the public test network were previously announced, including:
- P2P legal currency channel project ZKP2P supported by ZK certification
- Universal encryption trading platform Sequence
- Smart agent solution interconnection platform Superface
- Stablecoin wallet infrastructure Blockradar
- Stablecoin banking service Copperx
- Crypto API development company Crossmint
- Cross-border fund transfer and management program Hurupay
- Wallet infrastructure Para
- Personalized financial platform CFi
- Wallet based on zero-knowledge proof Hinkal
- Cross-chain infrastructure Axelar Network.
These projects will implement use cases in areas such as lending, capital markets, foreign exchange, payments, etc. on Arc. However, the specific construction progress of most projects has not yet been disclosed.
