Strategic Decision Analysis
Build vs. Generic Smart Contract Wallet
A detailed comparison of development approaches for mobile-first smart contract wallets, highlighting the trade-offs between custom development, generic SDKs, and a specialized service.
| Key Factor | Build In-House | Generic SDK/Provider | Chainscore Service |
|---|---|---|---|
Time to MVP | 6-12 months | 2-4 months | 4-8 weeks |
Initial Development Cost | $250K-$600K+ | $50K-$120K | $75K-$200K |
Smart Contract Security | Your responsibility (High Risk) | Shared (Medium Risk) | Our responsibility (Audited & Insured) |
Gas Abstraction (ERC-4337) | Custom implementation | Basic bundler integration | Optimized, multi-chain paymaster |
Multi-Chain Support | Per-chain development | Limited to SDK chains | Ethereum, Polygon, Arbitrum, Base, Optimism |
Recovery & Social Features | Full custom logic | Pre-defined templates | Custom social recovery, multi-sig, biometrics |
Ongoing Maintenance & Upgrades | Full internal team cost | Dependent on provider roadmap | Included in service SLA |

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, security-first approach to building and deploying production-ready smart contract wallets. We deliver predictable timelines, enterprise-grade security, and seamless integration.
01
Architecture & Specification
We design a modular wallet architecture tailored to your use case, defining account abstraction standards (ERC-4337/6900), recovery flows, and gas sponsorship models. This phase establishes a clear technical blueprint for predictable development.
1-2 weeks
Design Phase
ERC-4337/6900
Standards Compliant
02
Smart Contract Development
Our engineers write, test, and optimize core wallet logic—EntryPoint, Account Factory, Paymasters—using Solidity 0.8+ and OpenZeppelin libraries. We focus on gas efficiency, upgradability patterns, and comprehensive unit/integration testing.
