One-Click Sweeps (EIP-5792)¶
On wallets that support atomic batching, DustSweep bundles every approval and the sweep itself into a single wallet confirmation. This page explains how that works and what to expect, wallet by wallet.
What EIP-5792 is¶
EIP-5792 is a wallet standard that lets an app submit a bundle of actions (wallet_sendCalls) instead of one transaction at a time, and ask whether the wallet can execute the bundle atomically — all together, in one transaction, or not at all (wallet_getCapabilities).
For DustSweep this means: approve token A (exact amount) + approve token B + … + sweep becomes one prompt, one transaction.
How DustSweep uses it¶
- Capability check on connect. DustSweep asks your wallet whether atomic batching is available on Base. Possible answers:
supported(ready now),ready(available after a one-time wallet-managed account upgrade), orunsupported. - Delegation safety check. Batching is only attempted when your account is either not upgraded, or upgraded by the same wallet you are using — some wallets claim batching support on accounts upgraded elsewhere and then fail. See EIP-7702 Explained.
- Bundle submission. The approvals (exact amounts, to the sweep contract) and the sweep call are sent as one atomic-required bundle. DustSweep then tracks the bundle status until a transaction hash confirms.

Wallet-specific behavior¶
| Wallet | Behavior |
|---|---|
| Coinbase Wallet / Base Account | Full one-click. Up to 10 tokens: approvals + sweep in one prompt. Larger sweeps: exactly two prompts (approvals batch, then sweep) for reliable estimation. Gas sponsorship via paymaster when available. |
| OKX Wallet | One-click via OKX's own provider; if the account is freshly upgraded by OKX, batching is immediate. |
| MetaMask | Supports batching via its Smart Account upgrade, but DustSweep currently keeps MetaMask approval batching disabled by default for safety — MetaMask users get the Sign & Sweep path. Batch size is capped at 10 when enabled. |
| TokenPocket | Special handling: approvals are batched first with explicit gas, then the sweep is sent after allowances confirm — this avoids TokenPocket gas-estimation failures. |
| Other wallets | Anything reporting atomic capability gets the standard bundle; everything else uses Sign & Sweep. |
Wallet capabilities change frequently — per-wallet behavior to be re-verified before publication. See Supported Wallets Overview.
The one-time "account upgrade" prompt¶
If your wallet reports ready, the first batch triggers the wallet's own prompt to upgrade your account to a smart account (EIP-7702). This prompt comes from your wallet, not from DustSweep, is optional, and unlocks one-click batching going forward. Declining it simply routes you to Sign & Sweep.
Fallbacks — you are never stuck¶
If a bundle fails for a technical reason (not your rejection), DustSweep steps down automatically and tells you each time:
- Bundle approvals only, then send the sweep separately.
- Send approvals one by one, then the sweep.
A rejection by you is always final — DustSweep never re-prompts a rejected request through another path.
User Safety Note A batch prompt shows several actions at once. Verify: each approval is for an exact token amount to the DustSweep router, and the final action targets the same router. Your wallet's own upgrade prompt (if any) is wallet-branded — reject any "upgrade" prompt that appears outside your wallet's standard UI.
FAQ¶
My wallet supports batching — why did DustSweep use Sign & Sweep anyway? Most commonly your account is upgraded (delegated) to a different wallet, batching is disabled for your wallet brand as a precaution, or the capability check failed. The notice in the app states the reason.
Is a batched sweep safer or riskier than separate transactions? The on-chain result is identical; the contract enforces the same exact-amount approvals either way. Batching just reduces prompts.
What does "atomic" guarantee? All bundled actions land in one transaction — approvals can never be left dangling without the sweep executing.
