No single 'cheapest' hardware wallet is fixed: prices and supported coins change. To find the lowest-cost option that still supports Ethereum and Solana, compare entry-level hardware wallets from established vendors on their official sites (avoid reseller markups/scams). Check each vendor's current compatibility list for native or companion-app support of Ethereum (and EVM chains) and Solana. Key features to require: offline key storage, PIN, recovery seed backup, optional passphrase, open-source firmware where available, and a desktop/mobile companion app. Solana support is less universal than Ethereum, so confirm it explicitly; some wallets need a third-party wallet connector. Tradeoff: hardware wallets keep keys offline and are safer against malware, but cost money and are less convenient for frequent small transactions. Mobile/software wallets are free and convenient but are 'hot' (keys on an internet-connected device), so use them only for small amounts. If budget is tight, a basic hardware wallet can be the cheapest secure route, but do not sacrifice backup or vendor reputation. Prices vary; check official stores for current cost. Also verify firmware update policy and whether the device works with your phone/computer. Never buy a used or pre-initialized device.

Why Solana
Small ads need payments that don't each touch the chainAn ad here costs 0.003 to 0.004 USDC. A payment channelPayment channelA deposit locked once on Solana Devnet. Deliveries are paid by off-chain vouchers; one close transaction settles the final total. locks a deposit once on Solana; each accepted delivery is a signed off-chain voucherVoucherA signed off-chain authorization for the channel. Each one states the cumulative total owed so far.; one close pays the publisher. ClearVault's channel: open, voucher 1 (0.004 in total), voucher 2 (0.007 in total), close.
This run had 3 paid deliveries over 2 channels, so channels cost about as many transactions (4) as deliveries here. Illustration, not from this run: a channel still needs only one open and one close for 100 deliveries.Every transaction on the Solana explorerRun activity
