Network setup
XyloNet runs on Arc mainnet, Circle's Layer 1 for stablecoin finance, where USDC is the gas token.
What is Arc?
ArcArc is an EVM-compatible Layer 1 built by Circle. Instead of a separate gas token, transaction fees are paid in USDC, which keeps costs predictable and lets anyone holding stablecoins transact without acquiring anything else first.
Circle's stablecoins (USDC, EURC), CCTP v2 and Gateway are deployed natively, and finality is sub-second.

Decimals note
The native USDC balance the wallet shows uses 18 decimals; the ERC-20 interface at
0x3600000000000000000000000000000000000000 uses 6 decimals. Both are the same USDC.Add Arc to your wallet
Click below to add Arc mainnet to an injected wallet (MetaMask, Rabby, Coinbase Wallet and others). The Connect button in the app header does the same thing automatically when you switch networks.
CCTP v2 domains
Arc is CCTP domain 26. Native USDC moves between Arc and these chains by burn-and-mint, with no wrapped assets.
