What it means
Software or hardware that stores the private keys controlling your on-chain assets.
Why it matters when you trade
A wallet holds keys, not coins — the assets live on the chain and the key is the only proof of control. Hot wallets are convenient and permanently online; hardware wallets keep the key offline and sign transactions in isolation. Most losses are not cryptographic breaks but approvals granted to malicious contracts and seed phrases typed into the wrong page.
Worked example
A token approval granted once can be drained months later; revoking unused approvals is basic hygiene, not paranoia.
See it on live markets
DexLadder runs wallet against live market and pool data, with simulated capital, so you can watch it act on an order instead of reading about it — no account, no wallet, nothing installed.
