Sweepster fees: one skimmed fee, no gas to hold
Sweepster charges a single fee skimmed from the assets in motion at settlement — there is nothing to prepay and no gas to hold.
Fee table
The fee resolver picks the most specific rate that applies: a per-partner rate first, then a per-route rate, then a per-token-tier rate, falling back to the base rate below. A minimum-fee floor always applies on top, so very small sweeps still cover settlement cost.
| Rule | Rate | Notes |
|---|---|---|
| Base rate | 0.20% | Applied unless a tier, route, or partner override matches. |
| Tier override | configurable | Longer-tail or higher-risk token tiers can carry a different bps rate. |
| Route override | configurable | Specific source→destination routes can carry a different bps rate. |
| Minimum fee floor | $0.10 | Charged instead of the percentage rate when that rate would round below it. |
Worked example
Sweeping $1000.00 of USDC at the 0.20% base rate: the fee is $2.00, above the $0.10 minimum, so that's what's charged — you receive $998.00.
On a much smaller sweep — $10.00 — the 0.20% rate alone would work out to $0.02, below the 0.10 minimum floor, so the $0.10 floor applies instead: you receive $9.90.
Who pays gas
You never need native gas in the source wallet. Sweepster's relayer fronts gas on both the source settlement and any cross-chain delivery leg; reimbursement is atomic with the transfer — the same transaction that moves your tokens also pays us back out of the swept value, or the whole transaction reverts. There is no separate step where we've advanced gas and are waiting to be repaid.
