Winner of Everscale’s best web wallet contest, the 1GRAM project represents early foundational work in decentralized finance infrastructure development. This Vue.js-based wallet application demonstrated advanced capabilities in multi-chain cryptocurrency management, setting the stage for later institutional blockchain development.
“The technical challenges of building secure, multi-chain wallet infrastructure provided crucial early experience with blockchain development patterns that would later inform institutional digital asset platform architecture.” - Chris Wijnia, Co-Founder, Agio Digital Ltd.
Technical Architecture & Innovation
Built using a sophisticated Vue.js and TypeScript stack, 1GRAM implemented enterprise-grade security patterns and multi-chain interoperability:
Core Technology Stack:
- Frontend Framework: Vue.js 2 with Vuetify material design
- Language: TypeScript with ESNext features
- Blockchain Integration: TON Client for Everscale connectivity
- Cross-Platform: Cordova and Electron support for mobile and desktop
- Web3 Libraries: Ethers.js for Ethereum compatibility, Uniswap SDK integration
Multi-Chain Infrastructure Capabilities
| Feature | Technology | Strategic Importance |
|---|---|---|
| Everscale Integration | TON Client WebAssembly | Native blockchain connectivity |
| Ethereum Compatibility | Ethers.js, ERC20 token support | Multi-chain asset management |
| Security Architecture | BIP44 derivation, hardware-grade encryption | Institutional security standards |
| Cross-Platform PWA | Service workers, offline capabilities | Enterprise deployment flexibility |
| Developer Tools | GraphQL integration, contract abstraction | Extensible platform architecture |

Development Methodology & Architecture
The project showcased advanced software engineering practices:
// Example: Multi-chain wallet architecture
interface WalletProvider {
network: BlockchainNetwork;
balance(): Promise<BigNumber>;
sendTransaction(tx: Transaction): Promise<string>;
estimateGas(tx: Transaction): Promise<number>;
}
class EverscaleWallet implements WalletProvider {
// Everscale-specific implementation
}
class EthereumWallet implements WalletProvider {
// Ethereum-specific implementation
}
