Arcodian

Stablecoin-native launchpad, wallet, swap/bridge, and agent-economy infrastructure on Circle's Arc chain — a USDC-gas L1 built for real payments, not speculation-first tokenomics.

What's live on Arc Mainnet (chain 5042)

Launchpad, Swap/DEX, Bridge, Agent Pay, and the MCP server are deployed and operating with real USDC on mainnet — not a testnet demo. Agent Passport/Jobs/Reputation and Lend are noted per-row below where they're still Arc Testnet only.

Surface	What it does
Launchpad	Fair-launch bonding-curve tokens, native-USDC priced, automatic DEX graduation on threshold — no presale, no team allocation.
Swap / DEX	Uniswap-v3-style AMM (own deployment) + external-pool routing, live order flow in the trading terminal.
Bridge	USDC in/out of Arc via Circle CCTP, wired to Ethereum, Arbitrum, Optimism, and Base mainnets.
Agent Pay	On-chain payment rails for autonomous agents — invoices, spending policies, relayed/meta-transaction payments, atomic batch settlement (EIP-712, ERC-1271 smart-wallet support).
Agent Passport, Jobs & Reputation	ERC-8004 identity, a permissionless escrow job board, and an objective on-chain reputation/validation system for agent-to-agent commerce — live and fully functional on Arc Testnet only. The official ERC-8004 vanity proxies exist on Arc Mainnet (identityRegistry/reputationRegistry/validationRegistry in ARC_MAINNET_CONTRACTS) but still point at a MinimalUUPS placeholder pending the project owner's real-implementation upgrade — identity registration does not work through them yet.
Lend	Utilization-curve USDC/EUR lending market on a live Pyth oracle feed — Arc Testnet only; no official Arc Mainnet EURC or Pyth contract address is published yet, so ArcLendV2 can't deploy to mainnet.
MCP server	arcodian.fun/mcp — reads on-chain state and returns unsigned transaction builders only. It never holds a key.

Every contract address, verification status, and readiness gate is published and machine-readable at arcodian.fun/developers — see contracts.mainnet.json, mainnet-readiness.json, and verification-status.json. The Trust Center explains the wiring in plain language and re-checks it live on every page load.

Local development

npm install
npm run dev      # Vite dev server
npm run build    # production build
npx tsc -b        # typecheck
npx vitest run    # unit tests

Solidity contracts live in contracts/ (Foundry):

cd contracts
forge test

Repository layout

src/            React/Vite frontend (pages, wallet integration, config)
contracts/      Foundry contracts, tests, and deploy scripts
scripts/        Node.js indexers and keepers that feed the live app
public/         Static assets, SDKs (agentpay-sdk.mjs, gateway-erc1271-sdk.mjs), developer registry
mcp/            Arcodian MCP server (read + unsigned-tx-builder tools)
ops/systemd/    systemd units for every indexer/keeper running in production

Safety principles

• The frontend never stores a key or custodies funds — every state-changing action is a wallet-signed transaction the user approves.
• Arc Mainnet (5042) and Arc Testnet (5042002) are configured independently in src/config.ts and are never conflated.
• New product surfaces stay gated behind explicit on-chain bytecode checks and, where noted, a signed-off feature flag — see DEPLOYMENT.md.
• Quote and route providers fail closed: no route found means no swap offered, never a best-guess fallback.
