Smart Contracts

All ArcaneFi core functionality runs through smart contracts deployed on Arc. Addresses are publicly verifiable on Arcscan at testnet.arcscan.app.

Contract	Standard	Purpose
NFTFactoryV2	Custom	Deploys ERC-721 collections for users. Maintains a registry of all collections via getAllCollections(). Used by the NFT Gallery scanner.
MarketplaceV2	Custom	All listings, purchases, and offer logic. Enforces 2.5% platform fee and creator royalties. Atomic USDC ↔ NFT swaps.
NFTCollectionV2	ERC-721	Template for each user collection. tokenURI, totalSupply, maxSupply, mint, ownerOf, tokenOfOwnerByIndex.
ArcFiSBT	ERC-5192	Soulbound Token. One deployment per milestone. Non-transferable. Treasury-only mint. revoke() for ToS violations.

ArcFiSBT Contract

The ArcFiSBT contract implements ERC-5192 (soulbound standard) on top of ERC-721. Each milestone gets its own deployed contract instance. The treasury wallet is the only address that can call mint().

Solidity Interface

// ERC-5192 Soulbound Token — one deployment per milestone
interface IArcFiSBT {
  // Mint one SBT to recipient — onlyOwner
  function mint(address recipient) external returns (uint256 tokenId);
  
  // Bulk airdrop — onlyOwner
  function batchMint(address[] calldata recipients) external;
  
  // Revoke (burn) a token — onlyOwner, resets hasClaimed
  function revoke(uint256 tokenId) external;
  
  // ERC-5192 — always returns true (non-transferable)
  function locked(uint256 tokenId) external view returns (bool);
  
  // Check if wallet has already claimed
  function hasClaimed(address wallet) external view returns (bool);
  
  // Get original recipient of a token
  function tokenRecipient(uint256 tokenId) external view returns (address);
  
  // Get block timestamp when token was minted
  function mintedAt(uint256 tokenId) external view returns (uint256);
}

Deploy Script (Foundry)

Each SBT milestone contract is deployed via Foundry with a parameterised script. Edit four constants at the top before each deploy:

Bash — Deploy Command

cd amm && source .env

forge script script/DeployArcFiSBT.s.sol \
  --rpc-url https://rpc.testnet.arc.network \
  --broadcast \
  --private-key $PRIVATE_KEY

Verifying Contracts

All deployed contracts can be inspected on Arcscan at https://testnet.arcscan.app. Paste any contract address to view deployment transactions, source code (if verified), and all contract interactions.
