FREEBLOCK / CRYPTO WALLETS
NFT wallet
development
Build wallets for collections, game items and NFT marketplaces. Users can explore holdings, inspect properties and transfer tokens through a clear interface.
A standalone product or an embedded wallet for your platform.
01 / PRODUCT CAPABILITIES
A wallet designed around your collection
Games, marketplaces and collector apps have different workflows. Select networks, standards and operations before development.
Collections and inventory
Display holdings, media, traits and filters. Handle missing or updated metadata.
NFT transactions
Transfers, receiving and history. Add minting, listings or auctions through your product's contracts when needed.
Keys and permissions
Define custody and recovery. Make signing actions and granted permissions clear to the user.
02 / DELIVERY SCOPE
From indexing to NFT transfers
Start with a complete workflow: open a collection, select an asset, inspect terms and complete a transaction.
-
Product model
Define users, networks, NFT standards and key management.
-
Indexing and media
Connect ownership data, token properties and bounded media loading.
-
Wallet and integrations
Build transactions, history, signing flows and game or marketplace connections.
-
Tests and operations
Test ownership changes, unusual metadata, access and external-service failures.
03 / ARCHITECTURE
Decisions for an NFT product
- Custody model
- Custody can simplify some user flows but requires operator infrastructure. Self-custody changes sign-in and recovery.
- Networks and standards
- Specify supported standards and operations. Each additional network needs indexing, contract interaction and testing.
- Data and content
- Define metadata sources, refresh behavior and external-content display rules. Token ownership and media availability are separate states.
04 / FREEBLOCK EXPERIENCE
Real projects behind the work
NFT Power is our Ethereum NFT marketplace with NFT custody, backend, interface and smart contracts. This is relevant experience for embedded wallets, collections and token operations.

Correct ownership and clear transactions
Supported networks and standards are defined in scope. Collection-specific behavior needs validation before compatibility is promised.

08 / FAQ
Before we start
Is this a wallet I can download?
FreeBlock develops custom wallets for businesses: a standalone application or a module in your platform.
Can the wallet be embedded in a game?
Yes. We define sign-in, custody, inventory and transactions. Users should understand the difference between in-game records and blockchain operations.
Can the wallet support multiple networks?
Yes. Define the MVP networks and standards, then validate data retrieval and transactions for each integration.
Can you add NFTs to an existing wallet?
Yes. We review architecture, indexing, key management and interface, then scope collections, media and required transactions.
How do you estimate cost and timing?
After an initial discussion, we agree on the first release, supported networks and integrations. We estimate delivery by phase and list external costs separately, including infrastructure, third-party services and an independent audit if required.
What do we receive after launch?
You receive source code, documentation and deployment instructions within the agreed scope. Support, monitoring and future releases can be included in a separate delivery plan.
