Clear guides and checklists for safer swapping, fees, risks, and liquidity.

What this site covers

• How swaps work in AMMs: reserves, price impact, and slippage.
• Safety basics: phishing, token approvals, and MEV “sandwich” risk.
• LP reality: impermanent loss, v3 ranges, and strategy trade‑offs.
• Practical troubleshooting: why swaps fail and how to fix it.

How a Uniswap swap actually happens

A “swap” is a smart‑contract call signed by your wallet. The interface shows a quote, but the blockchain decides the final execution based on current pool state, routing, and the exact block your transaction lands in.

Quote → transaction → receipt

1. Quote: the interface estimates output based on pool reserves and the route it intends to use.
2. Settings: you choose slippage tolerance and confirm the “minimum received.”
3. Signature: your wallet asks you to sign a transaction (and pay gas) — this is the point of no return.
4. Execution: validators include the transaction in a block; pools update; your wallet balance changes.

Practical safety essentials

• Verify the token: for unfamiliar assets, confirm the contract address from a trusted source.
• Keep slippage reasonable: high slippage can lead to worse fills, especially in thin liquidity.
• Prefer limited approvals: approvals are necessary, but unlimited approvals are rarely necessary.
• Check the network: make sure your wallet is on the chain you intend to use and you have gas.
