FAQs
Below you’ll find answers to the most common questions about Kastle across mobile and browser extension. If you need support, reach out through our official channels on X, Telegram, or Discord.
🧭 General
Why does my Kastle wallet show a 0 balance even though the explorer shows my funds?
This is usually caused by temporary RPC congestion. Your funds are safe — if the Kaspa explorer shows the transaction as “received”, the wallet will sync once the RPC reconnects properly.
Why do transactions feel slow sometimes?
Transaction speed depends on network load and RPC responsiveness. Kastle broadcasts your transaction immediately, but confirmation time varies with network conditions.
Does Kastle have a public roadmap?
Yes. Major updates are shared in our docs, release notes, and on X. We typically release updates every two weeks.
Will Kastle support multiple languages (e.g., Chinese)?
Yes — full localization support (including Chinese) is planned and on the roadmap.
Why can’t I create a 24-word seed phrase in Kastle?
Kastle currently supports 12-word recovery phrases only. Support for additional mnemonic formats may be added later.
Can I export private keys from a wallet created from a seed phrase?
Not yet. Kastle only allows exporting private keys for wallets imported via private key. For seed-based wallets, private key export is disabled for security reasons.
Is Kastle open source?
Browser extension: Yes, available on GitHub.
Mobile app: Will be progressively open-sourced as internal components mature.
How can I check if I am using a Legacy EVM address and migrate safely?
Go to Settings → Legacy EVM Address:
If the toggle is off → you're using the correct address.
If the toggle is on →
Turn it off to reveal your standard EVM address
Transfer assets to this standard address
Keep Legacy mode off once funds are moved
Does Kastle support Ledger or Tangem on mobile?
Ledger: Mobile support is coming soon
Tangem: Also planned as part of upcoming hardware integrations
Extension: Ledger is already supported for Kaspa L1
Can I use Ledger with EVM / Kasplex / L2 networks?
Not yet. Ledger currently supports Kaspa L1 only. L2/EVM Ledger support requires a different implementation.
Is there a way to bridge from L1 KAS to L2 KAS within the wallet?
It's not available now, but it's in development and it's coming soon with the next update on mobile.
How do I transfer KAS from L1 to L2?
Use the official Kurve Bridge (Kaspa Foundation): 👉 https://kasbridge-evm.kaspafoundation.org/
How do I bridge KRC20 or KRC721 tokens?
Use the KAT Bridge, which is specifically designed for KRC-standard assets.
Does Kastle support KRC20 tokens? Can I hold them?
Yes — Kastle supports holding and viewing KRC20 tokens in both extension and mobile.
Which API does Kastle use to fetch KRC20 token prices?
Kastle uses Kasplex APIs for all KRC20 price and valuation data.
Are KRC20 swaps supported in Kastle?
No. Due to how KRC20 tokens are implemented (chunk-based buying/selling), swaps are not technically possible.
Will Kastle support swaps?
Yes — but only for L2 assets. Swaps for L2 tokens will be available soon through integrated DEX providers.
Can Kastle hold ERC-721 NFTs?
Yes. Kastle fully supports ERC-721 NFTs on L2 networks — including viewing, receiving, and transferring — on both mobile and extension.
Does Kastle support KRC721 NFTs?
Partially. Viewing is supported, full KRC721 transfer support is coming soon.
Can I buy or sell NFTs inside Kastle?
Not natively yet. Kastle supports transfers for ERC-721 NFTs, but buying/selling will become available through the in-app browser, which will let you access external marketplaces.
Why couldn’t I send NFTs previously on mobile?
This has now been updated:
ERC-721 transfers: Supported on both mobile & extension
KRC721 transfers: Coming soon
Is WalletConnect supported?
Extension: Already works with RainbowKit
Mobile: Not yet, integration is in progress Developer documentation will be published once support is live.
Will Kastle have an in-app browser?
Yes — this feature is coming soon and will enable:
NFT marketplace interactions
Token discovery
DEX integrations
KNS marketplace support
Can I expand the browser extension into a full-page view?
This feature is on the UX improvement list and being tracked.
Can the wallet be used to sign and interact with smart contracts?
At the moment no but the wallet already supports Kaspa L2s (Kasplex and Igra) and you can send and receive L2 tokens in those.
Is there a transaction history inside Kastle?
Yes — Kastle now includes full KAS transaction history, available on both:
Mobile app
Browser extension
More detailed token histories will be added progressively.
🧪 Testnet
How can I get test KAS or test tokens?
Use the official faucet: 👉 https://faucet-tn10.kaspanet.io/
Why doesn’t the wallet work on my PC or iPhone? Are my funds safe?
Yes — your funds are always safe on-chain. Issues usually stem from temporary RPC outages. Once resolved, the wallet will resume normal behavior.
Why does my Kastle wallet show a 0 balance?
This is due to RPC congestion. The wallet will sync as soon as the connection stabilizes, and your funds remain safe.
