Token safety check (local simulation, no GoPlus)

Running a local buy/sell, tax, mint/owner/proxy check…

Opens Coinbase Onramp in a new window. Coinbase handles identity checks (KYC), payment, and its own disclosed fees and spread. Funds go straight to your connected address on Base. This app never holds your funds and earns no fee on Coinbase purchases. Card availability depends on Coinbase; a Coinbase account may be required.

Sweep dust into USDC

Scans this wallet's listed Base tokens, skips dust below a USD minimum and tokens that fail the local safety check, and builds unsigned swaps into USDC through the fee router. Fees are disclosed on each plan. The wallet would sign the swaps one after another. Nothing is broadcast.

Fee: each dust swap pays the normal disclosed tier fee for its pair (majors / listed / long-tail), shown per swap below. No extra sweep fee. Gas can exceed the value of very small balances; check before signing.

Limit orders & DCA (signed intents)

You sign an EIP-712 intent in your own wallet. A keeper may only fill a valid, unexpired signature against a live quote. This build stores the intent locally and never broadcasts. Base only.

Non-custodial: your tokens stay in your wallet until a fill pulls exactly the signed amount through Permit2; this app never holds them. Fee: the disclosed tier fee for the pair per fill, the same as an instant swap. Positive-slippage (surplus) sharing is off on keeper fills: anything above your signed minimum stays with you. You can cancel any open intent (signed cancel here, plus an unsigned cancelNonce your wallet can send on-chain).

Referral link tracker

Share ?ref=yourcode. Clicks are stored locally. A disclosed share of the fee is computed for the referrer when a simulated trade is attributed. Nothing is paid out. See the stats page.

Read-only helper, not wired for Base in this dry-run (no explorer API key, no sign-up). Nothing is signed or sent.

No tickets prepared.

Fees & routing

Disclosed tiered fee, taken from the output and shown on the swap card before you sign: 10 bps majors · 50 bps listed · up to 100 bps long-tail. The pair pays the higher tier. Referrers receive a disclosed 20% of that fee; you pay the same either way. Cross-chain zap (API): a disclosed 15 bps bridge app fee collected by Across, plus the Base swap fee above; Across's own fees are shown separately.

Quotes compare Uniswap v3/v4, Aerodrome v2 and Slipstream, and PancakeSwap v3, and pick the best single or split route. The details show the saving versus a plain Uniswap single-pool quote. No hidden spread is kept; the only share of positive slippage is the disclosed surplus split below. Uniswap v4 pools whose hooks can change swap amounts are not routed. Tokenized stocks are not supported.

Positive slippage (surplus): if a swap through the fee router fills above the quoted net shown on the card, the extra is split 50% to you / 50% to the operator (operator cap 50%). Your signed minimum is never reduced. Off on Solana, on keeper-filled limit/DCA orders, and on the legacy direct-router path.

Limit orders & DCA: the same disclosed swap fee per fill; no extra order fee; surplus sharing off. Non-custodial: tokens stay in your wallet until a fill.

Tokens launched with this site's /launch tool: 50% of the Uniswap LP trading fees collected by the seeded position go to the operator treasury, 50% to the creator, permanently, via the LaunchLpFeeSplitter contract. No separate launch fee. Liquidity is not locked.

Cross-chain zap: a 15 bps (0.15%) app fee on the bridged amount, collected by Across through its official appFee and shown on the quote, plus the Base swap fee. Across's own bridge fees are separate.

Dust sweep: each swap carries the normal tier fee for its pair; there is no extra sweep fee.

Card purchases (Coinbase Onramp, when enabled): this app earns no fee. Coinbase charges its own disclosed fees and spread on its page.
