A stablecoin commerce app built natively on Arc Testnet - powered by Circle.
Live Demo · Report a Bug · Twitter · Telegram
Axoo is a Web3 application on Arc Testnet, Circle's stablecoin-native L1. It brings together onchain trade escrow, token swaps, cross-chain bridging, and stablecoin transfers into a single interface — built on Arc's officially pre-deployed ERC-8004 / ERC-8183 contracts and Circle's App Kit.
Access to the app is gated by a Genesis Pass NFT, an ERC-721 contract deployed by this project.

The Genesis Pass is the only contract deployed specifically for ARCora. Escrow and identity functionality build on Arc's shared, officially pre-deployed tutorial contracts rather than reimplementing them — Swap and Bridge run through Circle's App Kit / CCTP infrastructure.
- Node.js 18+
- npm
git clone https://github.com/Arcticoz/arcora.git
cd arcora
npm installnpm run devThen open http://localhost:3000.
Create a .env.local file in the project root:
PRIVATE_KEY=your_private_key
KIT_KEY=KIT_KEY:your_key_id:your_key_secret
NEXT_PUBLIC_GENESIS_PASS_CONTRACT=0x...
PRIVATE_KEYandKIT_KEYare server-only secrets — never commit them or expose them to the client.NEXT_PUBLIC_GENESIS_PASS_CONTRACTis safe to expose since it's a public contract address.
- Fully client-signed Swap flow (currently routed through a backend proxy due to CORS on Circle's Stablecoin Kit service)
- Autonomous agent provider for Trade Escrow — an automated wallet that listens for jobs and fulfills them without manual interaction
- Deeper integration with Circle Agent Stack (Agent Wallets, Circle CLI, Agent Marketplace)
Replaced the custom Solidity ERC-721 contract with Circle's official Smart Contract Template.
- Migrated deployment to the Circle SDK workflow
- Removed dependency on a manually maintained ERC-721 contract
- Standardized deployment according to Circle documentation
- Improved integration with the Circle Developer Platform
