- Circle’s Arc lets developers deploy ERC-20 tokens without writing Solidity, using pre-audited templates and EVM-compatible tools.
- Arc deployments use dev-controlled wallets funded with testnet USDC to handle contract admin, minting, and transactions.
- Circle webhooks enable real-time monitoring of mints and transfers, supporting dashboards and production tokenization workflows.
Circle Developer noted that deploying tokenized assets on Arc does not require writing Solidity from scratch. The guide, authored by Elton Tay, demonstrates how developers can deploy an ERC-20 contract on Arc Testnet. It includes steps using Circle Contracts, Templates, and Wallets, funding with testnet USDC, and monitoring contract activity in real time.
Setting Up Wallets and Funding for Arc Deployment
Developers first need a dev-controlled wallet on Arc Testnet. Wallets belong to a wallet set, so users must create a set, then a wallet within it. The wallet acts as the administrator for ERC-20 contracts and submits all transactions.
Testnet USDC is required for transaction fees. Developers can fund wallets via Circle Console Faucet or Circle Faucet. Once funded, the wallet can deploy contracts, mint tokens, and execute contract calls, establishing the operational base for tokenized assets.
Deploying and Minting ERC-20 Contracts
Using Circle Templates, developers can deploy pre-audited ERC-20 contracts without writing Solidity. The templates remain fully compatible with EVM tooling and expose the contract ABI for interaction. After setting deployment parameters, the Contracts SDK deploys the ERC-20 contract to Arc Testnet.
Once deployed, the contract begins with zero token supply. Completed mint transactions update wallet balances and record Transfer events, showing token creation and recipient addresses.
Monitoring Contract Activity with Webhooks
Circle offers real-time event monitoring through webhooks. Developers can track mints, transfers, and other contract events automatically, without polling or maintaining indexers. Event monitors watch for specific signatures, sending webhook payloads with transaction hash, block height, block hash, and decoded event data.
This monitoring enables dashboards, downstream workflows, or off-chain records for production tokenization systems. By combining Templates, Wallets, and webhook monitoring, Arc provides developers predictable infrastructure, stable execution costs with USDC, and integration with Circle-issued assets like USDC, EURC, and USYC.
Developers can explore Arc further using reference documentation, step-by-step tutorials, or by joining the Arc Community Hub, Arc Discord, or Circle Discord for guidance and collaboration.
