Enrique Souza engineered multi-chain wallet and DeFi features in the vultisig/vultisig-ios repository, focusing on robust cross-chain asset management, swap logic, and liquidity operations. He delivered end-to-end integrations for THORChain, Solana, Cardano, and EVM-compatible chains, implementing features like dynamic fee calculation, token discovery, and liquidity pool management. Using Swift and TypeScript, Enrique refactored service layers for maintainability, enhanced security scanning, and improved UI responsiveness through asynchronous programming and localization. His work addressed complex transaction flows, ensured accurate balance and price data, and streamlined token handling, resulting in a deeply integrated, reliable wallet experience with strong protocol alignment and extensibility.

November 2025 — vultisig-ios delivered multi-chain Sei integration with EVM capabilities, enhanced token selection, and a critical balance display fix. These changes broaden asset support, improve transactional UX, and ensure accurate balance representations aligned with unlocked funds. Implemented Sei assets and EVM services, added Sei RPC endpoint, and enhanced FunctionCallCustom for token selection and validation; fixed combinedBalanceDecimal to return only the available balance, surfacing staked/bonded in the DeFi tab. Result: reduced user confusion, expanded cross-chain capabilities, and stronger data integrity for wallet operations.
