Fees

Fee structure

Shaka charges a flat 2% fee on every payment, added on top of the deal amount and paid by the buyer. It’s hardcoded in the contract and split automatically:

• 1% goes to Shaka.
• 1% goes to the referrer wallet set when the deal was created (typically the creator’s own wallet) — Shaka’s way of routing what would otherwise be its own fee back to whoever brought the deal in. If no referrer is set, Shaka keeps the full 2%.

Recipients always receive 100% of the amounts set when the deal was created — the fee is never deducted from their payout.

There are no other fees on this flow. No subscription, no setup fee, no gas markup.

Calculating the total

Rather than computing the total yourself, call quote(dealId) — it returns the exact amount, in wei, to send to pay():

const grandTotal = await shaka.quote(dealId);
await shaka.pay(dealId, { value: grandTotal });

grandTotal is the sum of every recipient’s amount plus the 2% fee.

Example

A deal worth $10,000 total, split $7,000 / $3,000 between two recipients, created with a referrer set:

recipient A       = $7,000   (in full)
recipient B       = $3,000   (in full)
referrer (1%)     = $100
Shaka's fee (1%)  = $100
grandTotal        = $10,200  (what the buyer sends)

Gas costs

Gas is paid by the buyer, in ETH. Shaka does not add any gas markup. Typical cost on Ethereum mainnet is a few dollars, depending on network conditions.
