Who We Are

ClickMasters provides affordable blockchain and web3 services for businesses that need reliable digital solutions for their operations, customers, and growth. Our team works with startups, small businesses, and growing companies to plan, design, and develop software that solves real business problems.

Wallet Architecture Comparison Custodial vs Non-Custodial vs MPC vs Embedded

Custodial: Key Management Platform controls private keys. User trusts the platform. User Experience Simplest UX just a username/password. No seed phrases. Best For Exchanges, neobanks, corporate treasury management where regulation requires custody controls.

Non-Custodial (EOA): Key Management User controls private key / seed phrase. Platform has no access. User Experience User manages seed phrase. Self-custody, full ownership, full responsibility. Best For DApps, DeFi protocols where user self-custody is a core product value.

Non-Custodial (MPC): Key Management Private key split between user and platform neither holds the complete key. User Experience No seed phrase needed. Users can recover access. Platform cannot unilaterally move funds. Best For Institutional wallets, fintech apps, enterprise blockchain use cases requiring recovery options.

Embedded / Smart Wallet: Key Management EIP-4337 smart contract wallet key management via social login or MPC. User Experience Social login (email/Google). No seed phrase. Sponsored gas. Batch transactions. Best For Consumer apps, gaming, NFT platforms where crypto-native UX is a barrier to adoption.

MPC for Wallet Key Management

MPC (Multi-Party Computation) is a cryptographic technique that allows multiple parties to jointly compute a function (in this case, a digital signature) without any party revealing their input (their key share) to the others. In wallet key management: the user's private key is mathematically split into multiple shares, distributed between the user's device, the platform's server, and optionally a third backup. To sign a transaction, a threshold number of shares (typically 2-of-3) must participate in a distributed signing ceremony the complete private key is never reconstructed in any single location. Advantages over HSM-only custody: no single point of compromise (an attacker who compromises the server does not have the complete key), user recovery (if the user loses their device, the remaining shares can be used to generate a new key share), and better UX than seed phrases (no 24-word phrase to manage). Privy, Dynamic.xyz, and Fireblocks all use MPC for non-custodial or semi-custodial wallet key management.

Crypto Wallet Development Services We Deliver

ClickMasters operates as a full-stack crypto wallet development partner. Our team handles every layer of the software delivery lifecycle — product strategy, UI/UX design, backend engineering, cloud infrastructure, QA, and ongoing support.

01 / 05

Custodial Wallet Backend

Custodial wallet infrastructure for exchanges and financial platforms: HSM key management (Hardware Security Module private keys never exposed in plaintext, signing happens inside the HSM AWS CloudHSM or Thales Luna HSM for institutional-grade key security), MPC (Multi-Party Computation private key split between multiple parties using threshold signature schemes, no single party holds the complete key, k-of-n threshold required for signing), transaction approval workflows (multi-signature approval for large transactions, time delays for unusual patterns, fraud detection integration), regulatory compliance (KYC/AML integration, travel rule compliance for transfers above thresholds, transaction monitoring, SAR filing process). We build software that scales with your ambition from first-user MVPs to enterprise-grade, cloud-native systems. Whether you need a multi-tenant SaaS platform, a custom ERP, an API-first integration layer, or a cross-platform mobile app, our approach remains the same, clean architecture, production-ready quality, and infrastructure designed for 10x growth.

02 / 05

Non-Custodial Embedded Wallet

Embedded wallet infrastructure using managed SDK solutions: Privy (embedded wallet SDK email, social, or SMS login generates a non-custodial wallet, MPC-based key storage, no seed phrase for the user, supports EVM chains and Solana), Alchemy Account Kit (EIP-4337 smart contract wallets social login creates a smart wallet, gas sponsorship via Alchemy's paymaster, session keys, batch transactions), Dynamic.xyz (multi-chain embedded wallets with authentication combines traditional auth with Web3 wallet creation), integration pattern (embedded wallets created transparently when the user signs up users who are not crypto-native never see blockchain complexity). We build software that scales with your ambition from first-user MVPs to enterprise-grade, cloud-native systems. Whether you need a multi-tenant SaaS platform, a custom ERP, an API-first integration layer, or a cross-platform mobile app, our approach remains the same, clean architecture, production-ready quality, and infrastructure designed for 10x growth.

03 / 05

Multi-Chain Wallet Support

Wallet functionality across multiple blockchain networks: EVM chains (Ethereum, Polygon, BNB Chain, Avalanche, Base, Arbitrum, Optimism single key pair works across all EVM chains), Solana (separate key pair, different address format, @solana/web3.js for Solana interactions), Bitcoin (UTXO model, different address formats P2PKH, P2SH, P2WPKH bitcoinjs-lib or bitcoin-core RPC), chain detection (display correct network, warn on wrong network, support chain switching), cross-chain portfolio (aggregate balances across all supported chains in unified portfolio view). We build software that scales with your ambition from first-user MVPs to enterprise-grade, cloud-native systems. Whether you need a multi-tenant SaaS platform, a custom ERP, an API-first integration layer, or a cross-platform mobile app, our approach remains the same, clean architecture, production-ready quality, and infrastructure designed for 10x growth.

04 / 05

Transaction Management

Production transaction infrastructure: nonce management (track the nonce for each wallet address, increment correctly for sequential transactions, recover from nonce gaps after failed transactions), gas price estimation (use EIP-1559 base fee + priority fee estimation `eth_feeHistory` API for accurate gas pricing, configurable max fee and max priority fee), transaction broadcasting (submit transaction to the network via Alchemy or Infura, return transaction hash immediately, track confirmation status via WebSocket subscription or polling), transaction history (index historical transactions via Alchemy Transfers API or Etherscan API display full transaction history with token transfers, gas paid, and status). We build software that scales with your ambition from first-user MVPs to enterprise-grade, cloud-native systems. Whether you need a multi-tenant SaaS platform, a custom ERP, an API-first integration layer, or a cross-platform mobile app, our approach remains the same, clean architecture, production-ready quality, and infrastructure designed for 10x growth.

05 / 05

Hardware Wallet Integration

Hardware wallet support for high-security users: Ledger (Ledger Live SDK detect device, connect via USB or Bluetooth, prompt for account selection, sign transaction with device), Trezor (Connect SDK web-based and mobile integration, transaction signing flow, device detection), integration pattern (application detects if user has a hardware wallet, offers option to connect instead of software wallet, routes signing requests through device). We build software that scales with your ambition from first-user MVPs to enterprise-grade, cloud-native systems. Whether you need a multi-tenant SaaS platform, a custom ERP, an API-first integration layer, or a cross-platform mobile app, our approach remains the same, clean architecture, production-ready quality, and infrastructure designed for 10x growth.
