Before swapping tokens on Curve Swap, verify the connected wallet, token approvals, slippage settings, and transaction preview to avoid errors or unexpected outcomes. These checks help confirm the correct network, sufficient liquidity, and fair execution while keeping funds secure.

Confirm the official Curve website and wallet connection

Always verify you’re on the correct Curve Swap (please click the following web site) website before connecting a wallet. Check the URL and ensure it matches the official domain to avoid phishing scams. Once connected, confirm the wallet address displayed matches your intended account and that the selected network is the one where your tokens reside. If swapping cross-chain, use only official bridges or trusted interoperability solutions.

Review token approvals and allowances

Some tokens require explicit approval before swapping on Curve Swap. If this is your first time swapping a particular token, the interface will prompt you to sign an approval transaction. Verify the token contract address matches the intended asset, as malicious tokens may spoof legitimate ones. After approval, check your wallet’s token allowance settings to ensure you haven’t granted excessive permissions. For security, consider resetting allowances after large swaps.

Check liquidity pool depth and composition

Curve’s AMM pools work best when swapping between correlated assets like stablecoins or similar tokens. Before swapping, review the pool’s composition and depth for your token pair. Shallow pools or imbalanced reserves may lead to high slippage. The interface displays estimated price impact – if this percentage is unexpectedly high, consider splitting large swaps into smaller transactions or checking alternative pools. Remember that liquidity conditions change constantly across all decentralized exchanges.

Set appropriate slippage tolerance

Slippage tolerance defines the maximum price movement you’ll accept before the transaction fails. For stablecoin pairs, 0.1-0.5% often suffices, while more volatile pairs may need 1-3%. Setting slippage too low may cause failed transactions, while excessively high slippage risks unfavorable execution. Some wallets let you customize transaction deadlines – setting this too short may cause timeouts during network congestion. For more on slippage mechanics, see Curve’s swap documentation.

Verify the transaction preview and gas fees

Before confirming any swap, carefully review the transaction preview showing input/output amounts, fees, and price impact. Cross-check that the “minimum received” amount meets your expectations. Note that gas fees fluctuate based on network activity – you can adjust priority fees in most wallets to balance speed against cost. For Ethereum transactions, Ethereum.org’s wallet guide explains gas management techniques. If the preview seems incorrect, cancel and recheck your parameters.

Monitor transaction status after submission

After signing the transaction, monitor its status via your wallet or a blockchain explorer. Pending transactions may take minutes during peak congestion. If a transaction fails (due to slippage, insufficient gas, or other issues), you’ll only lose the gas fee, not the swapped amount. For complex swaps routed through multiple pools, you can review the execution path afterward. The Curve YouTube channel occasionally posts tutorial videos demonstrating the swap process.

By methodically checking these factors before each Curve Swap transaction, you can minimize errors, avoid scams, and achieve better execution. Always remember that decentralized finance requires personal responsibility – take time to understand each step rather than rushing through swaps.
