Transfer assets securely with a streamlined, privacy-focused flow designed to keep your keys safe.

The send token process is architected with security as the foundation:

Transaction Preparation — The UI gathers recipient address and amount, then requests transaction parameters from the background script. At this stage, only the sender's public address is used — no private key is accessed.
Gas Estimation — The system automatically calculates optimal gas fees using real-time network conditions, with support for both legacy and EIP-1559 transaction types.
User Confirmation — A dedicated approval interface displays all transaction details: amount, recipient, network fee, and total cost. Nothing is signed until you explicitly confirm.
Secure Signing — Only at the moment of confirmation does the background script retrieve the private key from encrypted vault storage, sign the transaction, and immediately clear the key from memory.
Broadcast — The signed transaction is sent to the network via redundant RPC endpoints with automatic fallback.

The entire flow is designed with a clear separation of concerns:

UI Layer — Handles user interaction and display, never touches private keys
Background Script — Isolated execution context with access to encrypted vault
Vault Encryption — Private keys stored encrypted at rest, decrypted only for signing
Memory Safety — Keys exist in memory only during the signing operation
