Download ArcSign for free and upgrade to Pro anytime from within the app.
Pro membership exists as an ERC-721 NFT on the BSC chain. Mint it directly in the app using USDT or BNB. The NFT is a digital asset you truly own — it can be transferred or sold. Each NFT is valid for 1 year and adds 3 wallet slots.
Absolutely. Free and Pro use the same encryption engine (XOR three-shard + AES-256 + mlock memory protection). Pro adds DeFi efficiency features (multiple wallets, batch revoke, best-route Swap) without affecting security level.
Free users: 0.1% fee. Pro users: completely free, plus automatic price comparison across multiple aggregators to find the best rate.
After expiry you revert to the Free plan — your wallets and assets are not affected. You simply cannot access more than 1 wallet. Purchase a new NFT to restore Pro benefits.
