LinkSpin The contract Live ledger Start free

The contract, in plain words

Every dollar on this platform moves through one smart contract on Polygon. It takes a package payment and splits it to real wallets in the same transaction. It has no balance to drain, no pause button, and no owner power over money. This page says what it does, with the source beside it. Verify every claim yourself. That is the point.

The rules it enforces

constants · no setters exist
Split50% to the buyer's sponsor, 20% to level 2, 10% to level 3, 10% + 10% to two platform wallets. Compiled into the bytecode. No function exists to change them.
QualifyingLevel 2 pays a member after two of their referrals buy a package of $25 or more. Level 3 after five. Qualification is earned by referred buyers and cannot be bought.
Pass-upsA share with no qualified member at that level climbs to the next qualified member above, up to 25 steps, then to the platform. Nothing waits in a balance.
Failed sendsPayouts are pushed with a strict gas allowance. A wallet that cannot receive is treated as unqualified and its share passes up. The purchase never reverts and never holds funds. Use a normal wallet address for payouts; some exotic smart-contract wallets cost more gas to receive than the allowance.
PricingPackages are priced in dollars. The POL amount comes from the Chainlink POL/USD feed at the moment you buy; a small overpayment refunds in the same transaction. A feed older than an hour falls back to the last good price for up to a day, then new purchases pause until it returns.
CreditsEach package mints ad credits to your account. Only the LinkSpin engine can consume them, only downward, only as your ads are delivered. Credits are not money and never pay out.
Owner powersAdd a product (price floor $1, ceiling $500), retire or reactivate one, queue a price change behind a public 24-hour timelock, rotate the platform wallets and the engine signer. That is the whole list. No pause, no upgrade, no withdraw, no edit of the split, no touch of anyone's membership or credits.

Rounding dust of a few billionths of a cent goes to the platform wallet so the books always balance to zero. Every one of these movements is an event on the live ledger.

What this is and is not

read before you buy
An ad purchase. Every package is advertising credits you spend on the network. Buy it because you want the ads.
Not an investment. There is no return on the package itself. Payouts come only from purchases made by people in your line, and only while they buy.
Your own wallet. LinkSpin never holds your POL. If you lose your keys, nobody can recover a payout for you.

The whole reason this platform exists is that you should not have to take anyone's word, including ours. Open the source, open the ledger, click a transaction.
