Swapping
One button at a time, and only the steps your wallet needs.
Approve, sign, swap
| You sell | Route | Steps |
|---|---|---|
| USDC | Uniswap | Swap (USDC is Arc’s native coin) |
| Any other token | Uniswap | Approve → Sign (free) → Swap |
| Any token | KyberSwap | Approve → Swap |
Approvals and signatures cover exactly the amount of that swap, never an unlimited allowance, so a later swap may ask you to approve again.
Slippage
Slippage is how far you allow the result to fall between review and execution. Auto uses 0.1% between stablecoins and 0.5% for everything else; you can pick 0.1%, 0.5%, 1% or up to 50%.
- Raise it for tokens that move fast or charge a transfer tax.
- Keep it low for stablecoins: a high slippage only lets you receive less.
Why swaps fail
Almost always because the price moved past your slippage. The swap is cancelled and only the network fee is spent. Kata re-quotes and simulates before your wallet opens, so most of these are caught before you send anything.
