Account Types & EIP-7702

A regular Ethereum private key account. Dust derives a per-stealth-address private key and uses it directly to sign and broadcast a transfer transaction. Requires ETH for gas — typically handled by the DustPaymaster sponsorship.

Default for stealth claims in Dust. A StealthAccount contract is deployed at the stealth address via CREATE2. The stealth private key signs a UserOperation — the EntryPoint contract deploys and drains the account atomically. Gas is covered by the DustPaymaster, so the claim is completely free for the recipient.

A minimal smart wallet deployed at a deterministic address using CREATE2. The address is pre-computable from the stealth key without deploying first — funds can be sent before the wallet exists on-chain, and deployment + drain happen in one sponsored transaction.

EIP-7702 (included in Ethereum's Pectra upgrade) allows an EOA to temporarily adopt the bytecode of a smart contract within a single transaction. This means a regular wallet can execute smart-account logic (like ERC-4337 UserOps or batch calls) without being permanently converted to a contract.

In Dust, EIP-7702 allows stealth addresses that are plain EOAs to claim funds with smart-account capabilities in one transaction — enabling advanced features like:

• —Batch claims from multiple stealth addresses in one tx
• —Social recovery of a stealth key (sign with guardian)
• —Auto-routing output to Privacy Pool deposit in one step
