Is Sweepster secure?

Sweepster is non-custodial and settles atomically: the same transaction that moves your tokens also pays Sweepster's fee, or the whole transaction reverts — there is no state where value has moved but payment hasn't, and no state where Sweepster holds your funds between steps.

Non-custodial, atomic settlement

Pull, swap, skim, and deliver all happen inside one on-chain transaction. If any step fails — a bad swap price, a reverted transfer, a failed bridge handoff — the entire transaction reverts and nothing moves. Sweepster is never in possession of your assets outside of that single atomic transaction.

Token Risk Engine (fail-closed)

Every token is screened before a quote is issued: liquidity-depth checks, oracle-vs-DEX price sanity, and an on-chain honeypot/sellability simulation. Any check that can't complete — a missing pool, an RPC error, an unreadable price feed — fails closed and the token is declined rather than assumed safe. There is no static allowlist standing in for this screen.

OFAC sanctions screening

Every quote request screens both the source wallet and the destination wallet against OFAC sanctions data before a quote is issued. A sanctioned address is declined; screening runs on the quote path, not as an optional or after-the-fact check.

Pause, circuit-breaker, and timelock

The settlement contracts carry an operator-controlled pause/circuit-breaker that can halt new sweeps, and an allowlist timelock — adding a new swap target or bridge to the allowlist takes effect only after a delay, while removing one is immediate. That limits how fast a compromised or mistaken configuration change can affect live settlement.

Where Sweepster is today

Sweepster is currently proven end-to-end on testnets; mainnet deployment is gated on an external security audit.
