Fees
Fees depend on the token. Read its own terms on its page. Signal's only fee is a share of the trading fee built into tokens launched on Signal; trading a token launched elsewhere pays Signal nothing, beyond the Helix fee on a cross-chain order.
What the ticket shows
Before you confirm, the ticket's cost line gives the trade's whole cost in dollars and percent, split into what it can prove: fees, tax, opening fee, price impact and gas. That line is the simplest way to know what a trade costs. The sections below explain where each part comes from.
Signal v4 tokens
Every trade in a Signal v4 pool pays a fee to the token's hook, in the asset the token trades against.
| Charge | Size | When |
|---|---|---|
| The fee | 0.5%, 1%, 2%, 3% or 5%, set at launch | Every buy and sale |
| Buy tax, sell tax | Up to 5% each, if the launch set one | Buys, or sales |
| Size fee | Up to 5% more, if set | A trade large against the pool |
| Deviation fee | Up to 5% more, if set | A trade that pushes the price away from its average |
| Opening fee | Starts as high as 99% and falls to the base, if set | Every buy and sale in the launch's first minutes, 90 at most |
| Network gas | The chain's charge | Every transaction, including one that reverts |
The fee, the larger tax, the size fee and the deviation fee together can never exceed 15%. Only the opening fee can be higher, and only until its clock ends.
Wallet-to-wallet transfers are never charged.
Who gets it. Signal's share comes first, out of every fee. The launcher divides the rest between holders, the creator, a buyback and burn, and locked liquidity, as the token's page shows. That division can be re-pointed later with 24 hours' notice; the rates cannot change. See Signal v4 launches.
A pair asset with its own cut. A token that trades against an asset which taxes its own transfers carries that asset's cut as well. PSTR keeps 10% of every move in and out. The ticket shows it as "tax".
Cross-chain orders
Paying for a coin on one chain with money on another goes through Relay. The fees figure on that ticket includes Relay's fee, Signal's Helix fee and gas on both sides.
Earlier launch types
Separate the token's tax from the exchange fee, conversion fee, reward performance fee and network gas.
| Charge | Applies to |
|---|---|
| Curve token trade tax | Buys and sells of the taxed token, before and after graduation |
| Curve platform fee | A separate curve charge if the token's stored terms specify one; current standard rows specify zero |
| Exchange pool fee | Pool swaps; separate from a graduated Curve token's trade tax |
| Conversion cost | A route that swaps the input or payout into another asset |
| Perp funding and venue trading costs | The reward position on HyperCore |
| Perp performance fee | Positive gains in each redeemed batch under its snapshotted terms |
| Network gas | On-chain transactions, including approvals and reverted transactions |
Standard spot Curve allocation
The current standard launch settings split the collected trade tax into 45% holder rewards, 45% buyback/burn allocation and 10% Signal. These are shares of the tax, not of the whole trade.
For a 1% tax on a 100-unit taxable amount, the tax is 1 unit: 0.45 for holders, 0.45 for burns and 0.10 for Signal, before any later conversion or rounding effects. Before graduation, the burn allocation waits in the pairing asset; after a pool is available it can buy and burn tokens.
The configuration expresses this in two stages: protocol_tax_bps = 1000 removes 10% of the tax, then dividend_bps = 5000 and burn_bps = 5000 divide the remaining 90%. Do not display those defaults as 50% + 50% + 10%.
Classic
Project X Classic currently offers 1% and 2% pool swap fee choices. The fee election determines the creator or holder share; venue deductions and the actual collected amount matter. /api/pad/terms describes current Classic defaults, not every historical token or Curve token. Hybra uses its own pool state and fee rules.
Current Classic defaults allocate 70% of collected LP fees to the elected creator/holder recipient and 30% to Signal. Hybra's supported HYBR holder route also uses a 70% holder allocation. These percentages apply to collectible fees after venue deductions, not to the full trade value; inspect each token's recorded terms.
Perp rewards
The standard performance fee is 10% of positive gains in each redeemed batch. Batches fix their own fee terms; inspect those terms. It is not a promise of charging only on net profit across all your trades or all batches. A losing batch has no positive-gain performance fee, but ordinary trading, funding, conversion and gas costs can still apply.
Separately, a permissionless cash push by an outside caller after the ledger's 10-minute grace period can deduct a 0.1% caller bounty, capped at 2 USDC per holder per push. Normal keeper pushes and the holder's own claim(token) do not deduct this bounty. See cash-out handling.
Units
100 basis points means 1%; 10000 basis points means 100%. Classic pool-fee values use parts per million: 10000 means 1%, and 20000 means 2%. Never interpret both scales as interchangeable.
