--- title: Sending description: Opening a wallet with a key or a recovery phrase, choosing the token, reading the fee estimate, and what the receipt records. --- **Send** is where SWOP signs and broadcasts a transfer. You open a wallet, choose what to send and where, check the fee, and sign. The signing happens on your computer; the network only ever receives the signed result. Unlike the Vault, this needs an internet connection. Reading a balance, detecting tokens, estimating gas and broadcasting all require talking to the network, and SWOP blocks the section rather than letting you work blind when it cannot reach one. ## Opening the wallet Paste or type your private key, or switch the selector to **Recovery phrase** and enter the words. Either can be scanned from a QR with your phone instead of typed. Check the network selector before you open the wallet. The network decides the address that comes out, which fee currency applies, and which explorer the receipt points at. A recovery phrase entered on the wrong network derives a different address, and it will look like your funds are missing when they are simply on the chain you did not select. Once open, SWOP shows your public address and the native balance, and starts detecting tokens. ## Tokens SWOP looks for tokens with a balance by reading history and balances for your address. Detection is not exhaustive. Some tokens do not surface automatically, and when one is missing you can add it by hand: open **Advanced options**, paste the token's contract address, and press **Add token**. The contract can be scanned from a QR as well. If token detection fails entirely — a rate-limited endpoint, a network problem — SWOP says so rather than showing an empty list. An empty list and a failed check are different things and are reported differently. ### Token risk Each detected token carries a risk marker: - **Safe** — a contract SWOP recognises - **Verify** — unknown, or carrying signals worth reviewing - **Malware** — flagged as malicious or high risk Treat it as a first filter, not a verdict. Safe means recognised, not endorsed, and Verify covers every legitimate token that simply is not on a known list. The one to take literally is Malware. Unsolicited tokens arriving in a wallet are ordinary and harmless in themselves. The risk begins when you go to the site they advertise and sign something there. ## Amount and MAX Enter the amount, or press **MAX**. MAX fills in the largest amount you can actually send, which for the native coin means the balance minus the estimated fee. Sending an exact balance fails, because the fee has to come from somewhere. For tokens, MAX is the full token balance — but the fee is still paid in the network's native currency. You need ETH on Ethereum, BNB on BNB Smart Chain, SOL on Solana, and so on. A wallet holding tokens and nothing else cannot move them, and SWOP tells you when the gas balance is insufficient instead of letting the transaction fail on-chain. ## The fee Three speeds — **Slow**, **Normal**, **Fast** — with the estimated cost shown for each, along with the current network gas price and priority fee. The speeds differ in what you offer to have the transaction included sooner. On a quiet network the difference is negligible. During congestion it is large, and Slow can mean a long wait. Solana and Bitcoin charge differently — SOL fees and sats per byte respectively — and SWOP estimates each in its own terms. When the estimate does not appear, something is wrong: no connection, the wrong network selected, or an invalid destination or amount. Do not sign without an estimate. An unpriced transaction is one whose cost you will find out afterwards. ## Checking before you sign Nothing on a public blockchain can be undone. A transfer to a wrong address is not recoverable by SWOP, by Siade Whales, or by anyone. Before pressing **Sign and send**, confirm: - The destination address, in full. Checking the first and last four characters is the habit that address-swapping malware is built around. - The amount, and the decimal point in it. - The asset — the native coin and a token with a similar name are not the same thing. - The network. The same address on a different chain is a different destination. ## After sending SWOP shows the transaction hash and follows the transaction until the network confirms it, moving from **Pending** to **Completed**. Pending means broadcast and accepted, waiting for inclusion. It is normal, and on a congested network it can take a while. A link opens the transaction in the block explorer for that network. ## The receipt **Download receipt** produces a record of the transfer: asset, amount, from, to, network, block number, transaction hash and the gas actually paid. It is a local file built from what the network returned. It is a useful record to keep, particularly if you are reconciling against the movements the website shows under [Transactions & P&L](/docs/wallet-transactions) later. ## Offline If SWOP cannot reach the selected network, sending is blocked and the section says so. This is deliberate. Without a connection there is no balance, no fee estimate, and no way to broadcast, so the alternative to blocking is a screen full of numbers that are not true.
