//R.03 — mechanics
Three calls, one resolvable name.
Arcname is a registrar plus a resolver. Both are immutable contracts on Arc. No off-chain dependencies, no oracles, no upgradeable proxies.
//STEP.01
Reserve a name
Search any name on Arc Testnet. If available, register on-chain for 1–10 years, paid in USDC.
registrar.register("jerallaire", years)
//STEP.02
Point it at an address
Set a resolver record once. The resolver maps your .arc name to any Arc address you control.
resolver.setAddr(node, 0x7a23…b41)
//STEP.03
Get paid by name
Anyone can send USDC to jerallaire.arc from a wallet, payment app, or CSV payroll batch. Resolution is read-only and free.
resolver.addr(node) → 0x7a23…b41
//R.04 — built on arc
Settlement-quality infrastructure, end to end.
USDCnative gas
Gas paid in USDC, not a volatile gas token. Predictable, dollar-based fees.
6decimals
Stablecoin-native precision. Names, prices, and fees all settle in tabular USDC.
0upgrades
Registrar and resolver are non-upgradeable. What you register today resolves the same way in ten years.
//R.05 — secondary market
A built-in marketplace for names already taken.
Bid, list, and transfer in USDC. Listings settle atomically on-chain via a single marketplace.fillOrder() call.
