The actions you’ll use 90% of the time.
Go to app.uniswap.org → Connect wallet → Select token pair → Enter amount → Review swap details → Confirm in wallet → Wait for tx confirmation. Always check the swap preview for slippage & price impact.
app.uniswap.org → Pool → New position → Select pair & fee tier → Set price range (e.g. ±10% of current) → Deposit both tokens → Confirm. You earn fees on every swap in that range.
stake.lido.fi → Connect wallet → Enter ETH amount → Review → Confirm → Receive stETH. Auto-compounds staking rewards. Unstake anytime via Lido or trade stETH on secondary markets.
app.aave.com → Connect wallet → Supply collateral (e.g. ETH, USDC) → Select asset to borrow → Choose variable or stable rate → Review health factor → Confirm. Keep health factor > 2 to avoid liquidation.
yearn.fi/vaults → Connect wallet → Pick a vault (e.g. yvUSDC) → Deposit → Vault auto-compounds yield strategies → Withdraw anytime. One-click yield without active management.
Always cross-check addresses on Etherscan. Scammers deploy fake frontends. The full PDF lists every address with links.
Test with $10–$50 before moving serious capital. Gas fees are wasted on mistakes — cheaper to make them at small scale.
Use revoke.cash to clean up token approvals you no longer need. Infinite approvals = infinite risk.
If you borrow, never let health factor drop below 1.1. Set price alerts on your collateral assets. Liquidation is instant on-chain.
A failed transaction still costs gas. Use ETH price estimation tools and set realistic gas limits. The PDF includes gas optimization tips.
