Fees

Slate charges one thing: a small builder fee, and only when you close a take or it settles. Opening a position is free, as are deposits and withdrawals, and there’s no monthly cost.

The builder fee

Hyperliquid lets an app attach a builder feeto the orders it routes, using a native mechanism called builder codes. Slate’s fee is fixed at 0.4%(40 basis points), and it’s shown to you before you commit. Opening a position is free; the fee applies only when you close a take early or when the market settles. It is the only way Slate earns.

• Close or settle a $10 position and the fee is four cents. Opening it costs nothing.
• It’s charged on the way out, when you close early or the market settles, never when you open.
• You authorise it once, the first time you take. Hyperliquid records that consent on-chain, capped at a maximum rate, so Slate can never quietly raise it on you.

What Slate does not charge

• Depositing funds is free.
• Moving funds onto Hyperliquid is free; the network fee is covered for you.
• Withdrawing your funds is free.

Where the fee goes

The builder fee accrues to Slate’s account on Hyperliquid in USDC. It funds the work of curating questions, writing the context you read, and keeping the room calm. Your own funds always stay in your control; the fee is only ever the small percentage shown before you commit.
