Getting Started

You need a wallet (MetaMask, Rabby, or any injected wallet) — or you can generate a fresh one right in the app. Everything below happens at sellpolia.com/app .

Buying SETH

1. Open the app and switch to the Buy tab.
2. Enter how much SETH you want to receive.
3. Choose your payment asset and chain — the native coin (e.g. ETH on Base) or a stablecoin (USDC / USDT / DAI). The app shows a live quote.
4. Set the Sepolia address that should receive the SETH (defaults to your connected wallet).
5. Confirm the transaction. Your wallet switches to the payment chain automatically. For stablecoins you’ll approve the token first, then pay.
6. SellPolia indexes the payment and delivers the SETH to your Sepolia address. Track it in the Orders tab.

Selling SETH

1. Open the app and switch to the Sell tab.
2. Send SETH to the vault address shown (a plain transfer on Sepolia). The minimum deposit is 1 SETH.
3. SellPolia detects the deposit on-chain and turns it into one queue order. Your position is set once the deposit confirms.
4. As buyers arrive, your SETH sells in FIFO order. You accrue a USD balance priced at your current seller tier.
5. Once your sold balance reaches the payout minimum (10 SETH), you’re paid in ETH on Base in the next daily payout run.

Set where you get paid

Your payout address (on Base) can differ from your selling address. Change it from the account panel — it sends a small Sepolia transaction to the vault, and the latest on-chain change wins. See Payouts.
