# Sell tokens

> Understand approvals and protected sell execution.

Selling lets another contract transfer the specified token amount from your wallet. ERC-20 allowance is therefore required.

## Curve sell flow

1. Enter the token amount and review the onchain `quoteSell` result.
2. The app calculates `minEthOut` from your slippage setting.
3. If allowance is insufficient, the app simulates an exact approval to the per-token curve and requests an approval signature.
4. It waits for the approval receipt, verifies success, and re-reads allowance until the confirmed state is visible.
5. It rechecks wallet, network, balance, allowance, quote deadline, and curve state.
6. It simulates `sell(tokensIn, minEthOut, deadline)` and requests the separate sell signature.
7. It reports success only after the sell receipt succeeds.

## Graduated-token sell flow

The spender is Uniswap's configured SwapRouter02 rather than the curve. The same approval-first rule applies. The swap uses the canonical 1% token/WETH pool and unwraps WETH output to ETH for the active wallet.

<Warning>
  Approval and sale can require two wallet confirmations and two gas payments. A successful approval does not guarantee the subsequent sell will succeed. Verify the spender and amount before approving.
