About the Project
SAI Wallet is a non-custodial multichain wallet that provides a unified interface for working with decentralized financial protocols across different blockchain networks.
Key Capabilities
Yield
Unified interface for staking stablecoins across different protocols and networks. A single model for strategy selection, quota acquisition, and position management.
Asset Exchange
Single screen for token exchange with automatic selection of the optimal execution route depending on asset types and networks.
Security
Non-custodial model: keys and signatures remain on the user’s side. Infrastructure builds routes but cannot sign operations.
Transparent Economics
Detailed breakdown of costs by components: network fees, cross-chain costs, exchange losses, and protocol fees.
Observability
End-to-end operation tracing across all networks with recording of execution artifacts (txHash, messageId) and statuses at each stage.
