TheoSwap.io is a Software-as-a-Service (SaaS) platform that allows game developers to map a player's NFTs to in-game items. This process does not affect the NFTs in any way, and the NFT never leaves your wallet.

TheoSwap.io generates revenue by charging a small fee on every transaction. The fee for upgrading an NFT (paid via card) is the greater of $1 USD or 5% of the total value. When an item is sold on the blockchain marketplace, the platform fee is the greater of 0.00015 (in the chain's native token, e.g. ETH) or 5% of the sale price. If the game developer has added their payout address, half of this fee is paid out to them and half goes to TheoSwap.io. See the Terms of Service and the Developer FAQ for full details on blockchain fees and developer payouts (including that fees are not back-paid and wrong addresses cannot be recovered).

Currently, TheoSwap.io supports Ethereum (ETH) and Polygon (POLY). We continuously evaluate new blockchain integrations to enhance our platform's capabilities.

Unfortunately, blockchain transactions are irreversible. Once an NFT is sold, it cannot be recovered through our platform. If you know the buyer, you may reach out to them directly to discuss a possible buyback, but this would be at their discretion.

Yes. Your NFTs never leave your wallet when using TheoSwap.io. We only read your wallet to see which NFTs you own—we never request transfers or access to your funds. You maintain full control of your assets at all times.

While you can browse games and view NFTs without an account, you'll need to create a free account to upgrade NFTs, purchase configurations, or sell items on the marketplace. Account creation is quick and only requires an email address.

No, the upgrade will not be removed. The upgrade will remain with the NFT and the new owner will be able to use it.
