About the Client
Our client, a mid-sized centralized crypto exchange with over 500,000 users across Latin America and South Asia, wanted to reduce asset transfers to third-party wallets like Trust Wallet and MetaMask. They partnered with us to build a branded, non-custodial wallet that seamlessly integrates with their exchange, supports multiple blockchain networks, and keeps users, transactions, and revenue within their own ecosystem.
| Industry | Crypto Exchange / Web3 |
| Location | Latin America & South Asia |
| Platform | iOS, Android & Browser Extension |
| Timeline | 8 Weeks (MVP) · 14 Weeks (Full) |
| Solution | White-Label Non-Custodial Multi-Chain Wallet |
| Key Focus | Security, Multi-Chain Depth & UX Parity |
The Challenge
Users compare every new crypto wallet directly to Trust Wallet and MetaMask. Anything slower, buggier, or less feature-complete gets deleted inside 48 hours. The bar is brutally high and the client needed to clear it fast, across 70+ chains, on two mobile platforms simultaneously.
Why Brands Need Their Own Wallet
Trust Wallet alone has 60M+ users. Every crypto exchange that relies on third-party wallets is handing a competitor direct access to their users' on-chain behavior, transaction history, and spending patterns. Owning the wallet means owning the relationship.
Total crypto assets held in self-custody wallets globally (2024).
Platforms that control the wallet control the entire user journey — from onboarding to DApp usage to exchange deposits. That's the competitive moat the client was building toward.
Partnership Impact
Delivered a production-grade, non-custodial multi-chain wallet that immediately competed with market leaders on features, performance, and user trust.

User satisfaction
We expected a basic clone, but what Suffescom delivered felt like a production-ready wallet our engineering team would actually use themselves. The key management architecture is notably more refined than what we’ve seen from other vendors, the DApp browser performed seamlessly from day one, and NFT rendering was noticeably faster than leading wallets in our testing. Within six months, 35% of our exchange users had moved their assets into our wallet. That’s the metric that truly reflects the impact.

Weeks 2–5
Mobile app UI builds such as portfolio dashboard, send/receive flows, DEX swap interface, DApp browser, WalletConnect integration, staking module, and NFT gallery across iOS and Android simultaneously.
Weeks 4–7
Independent smart contract and SDK security audit, device-matrix QA across 40+ devices, App Store and Play Store submission, phased user rollout, and post-launch performance monitoring.
Weeks 7–8
Project Challenges & How We Solved Them
Most wallet builders treat key storage as an afterthought. We built a tiered security model using device-secure enclaves (iOS Secure Enclave / Android Keystore) for encryption key storage, with biometric-gated decryption and optional passphrase hardening — all without asking users to navigate technical complexity.
✓ Solved — zero key compromise incidents post-launch
Rather than building 70 individual chain integrations, we designed a chain abstraction SDK with a unified transaction interface. Chain-specific signing, fee estimation, and RPC handling are encapsulated behind a single API. It is adding a new chain takes hours, not weeks. At launch: EVM, Solana, TRON, BNB, Cosmos, and Aptos all live.
✓ Solved — new chain added in under 4 hours on average
Users who get front-run or hit unexpected slippage never swap inside a wallet twice. We integrated 1inch and Jupiter aggregators across EVM and Solana, with pre-swap slippage simulation and clear worst-case output display that dramatically reduces failed swaps and support tickets.
✓ Solved — swap failure rate under 1.2%
DApp browsers in wallets are security nightmares if poorly sandboxed. The malicious sites can attempt to inject transactions. We built a fully isolated WebView environment with domain allowlisting, injected Web3 provider with explicit user-approval flows for every transaction request, and complete WalletConnect v2 protocol support.
✓ Solved — 500+ DApps tested, zero injection incidents
Fetching NFT metadata on-demand is slow and costly at scale. We built a background indexing service that pre-fetches and caches metadata and media for all tokens in a user's wallet, with progressive loading in the UI. It is making the NFT gallery feel instant regardless of collection size.
✓ Solved — NFT gallery load time under 1.4s
Aggregating live token prices across thousands of assets on 70+ chains without hammering RPCs required a smart caching and price-feed strategy. We combined CoinGecko and CoinMarketCap APIs with on-chain AMM price discovery for long-tail tokens, delivering accurate portfolio valuation that refreshes in under 3 seconds.
✓ Solved — portfolio refresh under 3s for 99% of users
