Buy STAU on Polygon

Pay with any stablecoin from any supported chain. We route the swap and bridge for you, and deliver STAU plus a 6% v$ cashback to the same wallet, on the same chain, in a single flow.

How this works

  1. 1. Choose what you pay with
    Select USDC, USDT, or v$ from any of the supported source chains (Ethereum, Base, BSC, Arbitrum, Optimism, Polygon).
  2. 2. Confirm target: STAU on Polygon
    Your target token is STAU. It will be delivered on Polygon to the wallet you connected.
  3. 3. We swap and bridge
    One transaction. We route your stablecoin through the best DEX and bridge combination — you sign once.
  4. 4. Receive tokens + 6% v$ cashback
    STAU lands in your wallet on Polygon. 6% of the USD value is minted as v$ and delivered to the same wallet, same chain.

What is 6% v$ cashback?

v$ is our on-chain loyalty asset. Every purchase through onchain.channel earns 6% back in v$, delivered instantly to your wallet on the destination chain. v$ is transferable, spendable, and can be used as payment for future purchases.

Non-custodial. Your wallet signs the transaction directly. We never hold your funds.
