It depends on the account. Private-key and seed accounts sign locally; Ledger keeps keys on hardware; Safe authority is shared by its onchain owners. View-only stores no signing secret. Bankr signs remotely through Bankr. Read [Account types](/accounts/account-types) instead of applying one custody label to all six models. ### What account types does WalletChan support? Private key, seed phrase, Ledger, view-only, Safe multisig, and optional Bankr remote signing. [Compare their behavior](/reference/account-behavior). ### What is the difference between my password, seed phrase, and private key? The password unlocks encrypted local WalletChan data. A seed phrase derives a family of accounts. A private key controls one account. Losing a password may require rebuilding from account backups; anyone with a seed/private key can control the corresponding funds. ### Can WalletChan recover a lost password, seed phrase, or private key? WalletChan cannot email or reconstruct one. Recovery depends on a valid backup, an authorized existing session, Ledger recovery, enough Safe owners, or Bankr account access. A destructive reset does not recover funds. ### Why is an account missing after I import my seed phrase? The address may use a later derivation index. Add/derive more addresses from the saved seed group and compare the exact `0x` address. WalletChan uses the standard EVM path `m/44'/60'/0'/0/N`. ### Can I reveal a private key or seed phrase with an agent password? No. Reveal requires an explicit master password. Ledger keys can never be revealed by WalletChan. ### Is the Shield recovery phrase the same as my wallet seed phrase? No. It is a separate wallet-wide Privacy Shield identity and cannot restore your public Ethereum accounts. ## Dapps, approvals, and signing ### What does connecting to a dapp allow? It lets the exact origin see approved addresses and request future actions. Connection alone does not move tokens or sign a message. Every action receives its own review. ### Is disconnecting a dapp the same as revoking token approvals? No. Disconnecting removes wallet access for the site. An allowance is an onchain token permission and remains until an onchain revocation changes it. ### What is an unlimited token approval? It lets the spender move a very large token amount without another approval. WalletChan shows strong warnings for detected unlimited increases. Reduce an editable approval or revoke it when no longer needed. ### How can I understand what I am signing? Check origin, signer, network, action, estimated changes, approval limits, clear-signing summary, decoded/raw calldata, and fees. Typed data and SIWE get a structured review. Reject if the readable and exact details disagree. ### What happens when simulation fails? A likely revert is blocked until a separate risk acknowledgement, where continuation is allowed. If simulation is unavailable, the request can still be risky; manually inspect origin, value, recipient, approvals, and decoded/raw data. ### Does a SIWE sign-in cost gas? No, but it produces a cryptographic proof that can log you in or authorize offchain terms. Verify the domain, address, URI, chain, statement, nonce, time limits, and resources. ### Can different tabs use different WalletChan accounts or networks? Yes. Injected dapp account/chain state is per authorized tab/origin. A pending request remains pinned to the account and chain that received it. ## Transactions and gas ### Why is my transaction pending? Common reasons include network congestion, low replacement fee, earlier nonce ordering, RPC/receipt delay, remote Bankr processing, bridge settlement, or a Safe proposal awaiting approval. Open Activity for the exact stage. ### How do I speed up or cancel a transaction? Open an eligible pending private-key, seed-phrase, or Ledger native-gas transaction and choose **Speed Up** or **Cancel**. Both use the same nonce and a higher fee. Safe, view-only, fee-token, force-inclusion, and Bankr paths are not eligible. ### Can WalletChan reverse a confirmed transfer? No. EVM transactions are irreversible after confirmation. A pending cancellation is only a competing same-nonce replacement and is not guaranteed. ### Why is MAX less than my ETH balance? Native MAX reserves buffered gas and fee headroom. Spending the full balance would leave no fee for the transfer. ### Can I pay gas with USDC or another token? On eligible chains and account/delegate states, yes. The picker displays the current supported tokens and a bounded quote. Ledger and view-only cannot use token-paid gas, and native gas remains the fallback. ### What does Reset Nonce Cache do? It clears WalletChan's local nonce allocator state. It does not cancel or drop an onchain pending transaction. ### Why did my transaction fail? Inspect the detail error and receipt. Possible causes include contract revert, insufficient balance/gas reserve, expired quote, invalid nonce, underpriced replacement, RPC mismatch, partially completed sequential calls, or a rejected hardware/remote signer. ## Networks, tokens, swaps, and bridges ### Which networks does WalletChan support? WalletChan has [25 built-in mainnets, related testnets, and custom EVM networks](/overview/networks). Swaps, bridges, Safe, fee tokens, delegation, force inclusion, and Bankr remote signing each support a subset. ### How do I add a custom EVM network or RPC? Use **Settings → Chains → Add network**, or approve a valid dapp EIP-3085 request. Verify chain ID, RPC, explorer, and native token. You can save multiple named endpoints. ### How do I add or hide a token? Use portfolio options to add an ERC-20 contract or hide tokens. Hidden tokens remain onchain and can be restored under **Currently Hidden**. A dapp's watch-asset request also needs explicit approval. ### Why is a token balance visible but its USD value is missing? The onchain balance can load without reliable price data. A missing price is not a zero balance. ### Why is Swap unavailable or not quoting? Check account type, supported chain/token, balance, liquidity, RPC health, token metadata, and quote service. The built-in shortcut does not currently support Ledger; use a swap dapp and approve its ordinary transaction on-device. ### What is slippage? The tolerated difference between quoted and executed output. Higher slippage raises the allowed price movement and can lead to a worse execution. Review minimum received. ### Why have my bridged tokens not arrived? Source confirmation and destination delivery are separate. Check Activity for Bridging, Complete, Refunded, Expired, or Cancelled and open the available source/destination explorer links. ### Can a Safe bridge funds through WalletChan? Not through the built-in bridge. Safe same-chain Send and Swap proposals are supported; bridge is disabled until destination Safe deployment and authority can be verified. ## Smart accounts, Safe, and Ledger ### What is smart-account setup? For eligible private-key/seed accounts, WalletChan can set an EIP-7702 delegate on one network to enable atomic batches, token-paid gas, and constrained permissions. It keeps the same address and can be revoked. ### Can WalletChan batch multiple transactions? Yes through supported ERC-5792 dapp requests or a user-assembled cross-dapp batch. Atomic versus sequential behavior depends on account, chain, delegate, and whether the dapp requires atomic execution. ### What are delegated permissions? ERC-7715 permissions are reusable onchain authority bounded by token, amount, frequency, method, start, and expiry. Only eligible master-authorized local accounts can grant them. Disconnecting the dapp does not revoke them. ### How does a Safe transaction work? An owner proposes or approves. The Safe's threshold and nonce decide when it can execute. The executor sends the outer transaction and pays its gas. Future-nonce proposals can be signed/published but wait for their nonce before execution. ### Can I use Ledger with WalletChan? Yes on Chromium/WebHID for normal transactions, supported messages/EIP-712, Send, sequential staking legs, Safe owner actions, and Shield paths. The built-in Swap/Bridge, ERC-5792, fee-token gas, EIP-7702/ERC-7715, and force inclusion are not offered. ## Privacy, browser, and agent access ### What is Shielded ETH? It is WalletChan's wallet-wide ready balance in the configured Ethereum Privacy Pool. The public deposit is visible; withdrawal privacy depends on the selected route and your broader usage pattern. ### Why is a Shield deposit not ready? It can be awaiting the Ethereum receipt or the compliance/association-set stage. WalletChan separates pending from ready balance and shows approximate progress rather than treating confirmation as instant privacy readiness. ### Can an agent password or view-only account use Shield? No for initialization, shielding, withdrawal, reveal, restore, rescan, or public recovery. Privacy authority is master-only; view-only has no signer. ### How do I open `.eth` or `.gwei` websites? On Chromium, open **WalletChan Browser** and enter the name, or enable supported address-bar browsing. Configure public or local Kubo gateway behavior in Settings. ### What can the agent password do? It can authorize ordinary eligible transactions/signatures but cannot reveal secrets, change accounts/credentials/factors, grant new reusable authority, operate privacy authority, or reset. Ledger still asks for physical approval. ### What is the difference between WalletChan RPC and MCP? [WalletChan RPC](/developers/walletchan-rpc) exposes local Ethereum JSON-RPC for scripts/tools. [WalletChan MCP](/developers/walletchan-mcp) exposes structured agent tools and optional advanced execution profiles. Both are separate local packages, not hidden extension screens. ### Can I turn sounds off or change auto-lock? Yes. Use **Settings → Sounds** and **Settings → Security → Auto-Lock**. Manual Lock is always available from Home.
