Web3 Wallet Development Services

Develop wallet applications tailored to your product requirements and supported blockchain networks.

We help organizations plan custom wallet functionality for users who need to interact with blockchain accounts and authorized decentralized services.

A custom wallet may include account interfaces, transaction preparation, asset information, network configuration, and DApp connectivity. The development scope depends on whether the application creates and manages wallet credentials or connects with existing wallet providers.

Potential functionality includes:

• Blockchain account interfaces
• Supported account creation workflows
• Wallet dashboard development
• Network selection
• Balance and activity displays
• Transaction preparation
• Message-signing workflows
• Token information retrieval
• DApp connection features
• Security and configuration settings
• Account recovery interfaces where supported

The proposed wallet architecture must define signing authority and private-key responsibilities before implementation.

Plan self-custodial wallet experiences where users maintain control of the relevant signing credentials.

A non-custodial wallet is designed around user-controlled authorization rather than an application operator holding assets on behalf of customers. These products require careful key management, account setup, transaction presentation, and recovery planning.

The application should communicate clearly what the user controls and what assistance the service provider can or cannot offer.

Potential features include:

• Self-custodial account onboarding
• Supported wallet credential generation
• Secure signing architecture
• Local authentication controls
• Transaction approval interfaces
• Account and network management
• Wallet backup guidance
• Recovery procedures supported by the account model
• Secure transaction history displays
• DApp connectivity

Loss of credentials may result in permanent loss of access when no valid recovery mechanism exists.

A non-custodial wallet should not promise that its operator can recover an inaccessible account without the required authorization or recovery materials.

Evaluate wallet systems where an authorized provider controls signing credentials or performs transactions for customers.

Custodial wallet applications have different requirements from self-custodial products. The architecture may involve secure key-management infrastructure, customer account administration, transaction authorization, operational controls, and recovery procedures.

Custodial systems can also require additional legal, financial, operational, and regulatory assessment.

Potential architecture requirements include:

• Customer account management
• Custody responsibility definition
• Secure signing services
• Multi-level authorization
• Transaction approval policies
• Administrative controls
• Audit and activity records
• Key-management architecture
• Operational monitoring
• Incident and recovery procedures

Actual custody capabilities, security arrangements, regulated partners, and licensing requirements must be established before development commitments.

Technical development alone does not authorize a business to operate a custodial financial service.

Build wallet experiences for multiple supported blockchain networks where technically appropriate.

Some Web3 applications require users to view or interact with accounts and assets across more than one blockchain. Multi-chain functionality must account for differences in address formats, transaction structures, signing mechanisms, fees, and network behavior.

Potential features include:

• Multiple supported networks
• Network selection and switching
• Chain-specific account information
• Asset balance retrieval
• Transaction history by network
• Network fee information
• Supported token displays
• Network-specific signing workflows
• RPC provider connectivity
• Network compatibility checks

A network selector alone does not provide reliable support for every blockchain.

Multi-chain architecture requires explicit network selection, supported asset definitions, integration testing, and appropriate security review.

Create suitable mobile wallet experiences for supported Android and iOS environments.

Mobile wallet applications must account for device security, application lifecycle behavior, user authentication, and transaction confirmation. The implementation may involve native Android, native iOS, or an appropriate cross-platform architecture, depending on the product's requirements.

Potential mobile wallet functionality includes:

• Mobile wallet onboarding
• Account dashboards
• Supported blockchain balances
• Transaction preparation and review
• QR-based address interactions
• Biometric access where supported
• Secure local storage integration
• Network configuration
• DApp connection journeys
• Transaction notifications where supported

Mobile security capabilities vary across device models and operating-system versions.

The application must not assume every device offers identical key-protection or authentication capabilities.

Build browser-based wallet experiences or suitable wallet-connected web applications.

Some products require wallet-related features within a website or browser environment. The scope may involve a web wallet interface, existing wallet-provider connectivity, or specialized browser extension requirements. These are different security architectures and should be assessed separately.

Potential functionality includes:

• Web-based wallet dashboards
• Compatible wallet-provider connections
• Account information displays
• Network detection
• Wallet authorization requests
• Transaction review screens
• DApp connectivity
• Browser-specific session handling
• Supported extension integrations
• Error and reconnection management

Browser extensions and browser-based signing systems introduce additional security considerations, including untrusted websites, malicious requests, and software supply-chain risks.

Connect compatible wallet experiences with supported decentralized applications.

DApp connectivity allows users to authorize selected interactions with blockchain-connected products. Depending on the chosen ecosystem and integration approach, wallet connections may use suitable provider APIs, WalletConnect-compatible services, or other approved technologies.

The application should distinguish account connection, message signing, and transaction approval.

Potential features include:

• Wallet connection requests
• Session establishment
• Supported DApp communication
• Chain and account selection
• Message-signing requests
• Transaction authorization
• Session status handling
• Disconnect and session-management controls
• Rejected request handling
• Permission-related user guidance

Connecting a DApp does not mean every connected application or smart contract is safe.

Users should understand the access or transaction authorization they are being asked to approve.

Evaluate programmable blockchain account architectures for suitable Web3 products.

Smart contract wallets use supported smart contract functionality to implement account validation or authorization rules. Depending on the architecture, they may support capabilities different from traditional externally owned accounts.

Suitable approaches can include account-abstraction patterns where supported by the target blockchain.

Potential capabilities include:

• Smart contract account architecture
• Custom authorization rules
• Multi-signature approval models
• Session permissions where supported
• Transaction policy controls
• Recovery mechanisms defined by the account design
• Bundled transaction workflows where supported
• Approved account management interfaces
• DApp and contract integration
• Monitoring and administrative safeguards

Account-abstraction features depend on supported standards, contracts, bundler or provider infrastructure, and network capabilities.

Custom recovery, sponsored transactions, and advanced authorization are not automatic features of every smart contract wallet.

Create understandable transaction authorization workflows for supported blockchain operations.

Transaction signing is a critical wallet function because it may authorize irreversible changes or movements of digital assets. The wallet interface should help users understand the intended action before confirmation.

Potential development requirements include:

• Transaction construction
• Recipient and network presentation
• Amount and asset information
• Fee and gas-related displays
• Supported message signing
• Transaction authorization
• Rejection and cancellation handling
• Pending transaction tracking
• Transaction receipt retrieval
• Confirmation status display
• Failed transaction reporting

Wallet software should not show an operation as successfully completed merely because it was submitted to a network provider.

The final transaction status must be established using an appropriate network-specific verification method.

Display approved digital asset information through suitable blockchain interfaces.

A wallet may help users view supported native assets and compatible blockchain tokens. Asset displays depend on network information, approved token contracts, metadata providers, and indexing services.

Potential features include:

• Native network asset balances
• Supported fungible token displays
• Selected NFT information
• Asset activity history
• Token metadata retrieval
• Custom token configuration where suitable
• Balance refresh handling
• Relevant contract interactions
• Asset visibility settings
• Unsupported asset guidance

Token metadata and pricing can be incomplete, inaccurate, or manipulated.

Wallet applications should distinguish verified technical information from untrusted labels, third-party prices, or promotional data.

Plan appropriate protection for sensitive wallet functions and authorization credentials.

Wallet security must consider the full architecture, including key creation, storage, signing, account recovery, application permissions, and administrative access. The security model depends significantly on whether users control their credentials, the operator manages custody, or a smart contract account supports alternative authorization.

Potential security requirements include:

• Cryptographic key-management assessment
• Secure credential storage
• Hardware-backed protection where supported
• Transaction signing security
• Application authentication
• Recovery architecture review
• Access-control testing
• Secure dependency management
• Threat modeling
• Security monitoring
• Independent specialist assessment

High-risk signing and custody components may require qualified independent security reviewers.

No wallet should be described as guaranteed secure solely because it uses encryption or a particular blockchain.

Define wallet recovery and account-control procedures according to the selected architecture.

Recovery requirements differ between traditional self-custodial wallets, custodial accounts, and smart contract wallets. The project must establish which recovery mechanisms are technically possible and who is authorized to use them.

Potential functions include:

• Account setup guidance
• Supported recovery workflows
• Backup verification interfaces
• Credential-loss warnings
• Account authorization management
• Multi-device access where supported
• Recovery-related user education
• Session revocation where applicable
• Account migration planning
• Security event handling

Recovery must be based on real architectural capabilities, not on unsupported promises.

Private keys and wallet recovery phrases should never be requested through ordinary customer support or project enquiry forms.

Connect wallet functionality with suitable websites, mobile applications, and business systems.

Businesses may want wallet-based authentication, token-related functionality, or blockchain transactions within existing applications. The implementation can use compatible wallet providers and application APIs where supported.

Potential integration requirements include:

• Wallet-based application sign-in
• Authorized account association
• Blockchain information retrieval
• Smart contract interaction
• Token-enabled feature access
• Transaction verification
• Application API integration
• Backend event processing
• User permission enforcement
• Activity reporting

Wallet ownership or a successful signature does not automatically verify a person's legal identity.

Applications with regulated identity requirements must implement the necessary additional controls.

Maintain and enhance existing wallet software through defined technical services.

Existing Web3 wallets may require updates to network integrations, security dependencies, wallet connection protocols, interface behavior, or mobile compatibility. We review the existing codebase and sensitive architecture before recommending modifications.

Potential activities include:

• Existing wallet code assessment
• Wallet UI/UX modernization
• Network provider updates
• Transaction handling improvements
• Supported wallet protocol upgrades
• Backend integration maintenance
• Security-related remediation
• Authentication improvements
• Compatibility testing
• Monitoring and incident investigation
• Approved feature enhancements

Maintenance and production access responsibilities should be documented in the project agreement.
