About Social Space KrayChat End-to-end encrypted messaging between wallets (ECDH + AES-256-GCM). DMs, groups, voice messages, and chat sessions exposed to approved sites via the extension provider. Explorer & activity In-app activity history. KrayScan for inscriptions, transactions, addresses, runes, and L2 activity — without leaving the wallet. Platforms Two homes, one custody model Chrome extension MV3 extension for Chrome, Brave, and Edge.

Think relationship graph and public timeline (post, follow, engage), built around Bitcoin inscriptions and L2 NFTs — not a custodial Web2 account. Profiles that are assets Your social face is an inscription or L2 NFT you own. Open a Social Profile from KrayWallet (mobile) or on kray.space. Followers attach to that asset — not to a username rented from a platform. Feed like a real network Public feeds with recent and trending posts. Post text and media, comment, like, repost, and follow other inscriptions. Rankings surface active inscriptions and users. Wallet-signed actions Engagement is signed from KrayWallet. Sensitive social actions go through the same self-custodial confirmation model as the rest of the stack. Live surface today: kray.space/social . Not KrayChat Social Space is the public social layer (timeline, follows, posts). KrayChat is private messaging (E2E DMs, groups, voice). Both live in the KrayWallet / kray.space ecosystem — different jobs.

KrayWallet cannot freeze, move, or recover your funds — only you can, with your mnemonic. The oath: mnemonic never leaves the device · all signatures are local · we cannot freeze or access your funds · your Bitcoin remains yours even if we disappear · the code is open. Vault encryption Your seed is encrypted at rest with AES-256-GCM . The encryption key is derived from your password via PBKDF2-SHA256 (210,000 iterations on the PWA; extension uses the same family of primitives). The password itself is never stored — only a temporary session key exists while the wallet is unlocked. Standards BIP39 — 12 or 24-word mnemonic; optional passphrase (25th word) on restore. BIP86 — Taproot (P2TR) addresses. BIP-340 — Schnorr signatures for messages and Taproot spends. Local signing Bitcoin transactions, Ordinals/Runes PSBTs, and L2 authorization messages are signed on your device. Websites never receive your password. Sensitive actions (cancel listing, Dev Scrolls, KrayChat admin, L2 tx messages) always open a confirmation UI in the extension. Origin approval On the Chrome extension, the first time an unknown site calls connect() / requestAccounts() , you must approve that origin. Until approved, other API calls are rejected. kray.space (and subdomains) and localhost are auto-approved. Approval is remembered per origin. What we cannot do We cannot see or transmit your mnemonic. We cannot reset your password without the seed — write recovery words on paper. We cannot reverse a broadcast Bitcoin transaction. Exchanges can freeze accounts; a self-custodial wallet cannot be frozen by us. Open source Audit the extension at github.com/tomkray/kraywallet-extension .

Your seed phrase and private keys are generated on your device, encrypted with your password, and never leave your device . We do not collect, store, sell, or share personal data. No analytics, no trackers, no accounts. 1. What we do NOT collect No seed phrases, private keys, or passwords — encrypted locally and never transmitted. No personal information (name, email, intentional IP logging, device fingerprinting for ads). No analytics, telemetry, or usage tracking of any kind. No browsing history. The extension content script only exposes window.krayWallet — it does not read page content. 2. What is stored locally Extension: encrypted wallet in chrome.storage.local ; preferences and cached public data for performance. PWA: encrypted vault in browser localStorage (or secure storage on native builds). Removing the extension or clearing site data deletes the local vault. Funds remain on Bitcoin and can be restored from your seed phrase. 3. Network requests To show balances and broadcast transactions you initiate, the wallet queries public Bitcoin infrastructure and Kray services: kray.space — L2 balances, marketplace, bridge, and APIs you use. mempool.space / blockstream.info — UTXOs, fees, broadcast. ordinals.com — inscription and rune metadata. Requests contain public blockchain data (addresses, transactions you choose to broadcast). We do not attach identity to them. 4. Transaction signing All signing happens locally. Only the final signed transaction or message — public once broadcast or submitted — leaves the device. Website signature requests require your explicit approval in the extension. 5. Extension permissions storage — save encrypted wallet locally. activeTab / tabs — open explorers and connect to the active site. alarms — auto-lock after inactivity. Host permissions — blockchain and Kray endpoints only. 6. Open source & contact Source: github.com/tomkray/kraywallet-extension . Questions: Contact .

We never hold your private keys or Bitcoin. You alone control your funds. These terms are for the wallet product — not a substitute for the KRAY L2 platform terms on kray.space. 1. Software license KrayWallet is provided as open-source / freely downloadable software for personal use to interact with Bitcoin and related Kray services. You may use it at your own risk. 2. Self-custody You generate and store your own mnemonic and keys. We cannot access, recover, reverse, or freeze your wallet or on-chain funds. Loss of your seed phrase or password without backup may result in permanent loss of access to funds. 3. Your responsibilities Back up your recovery words offline (paper or equivalent). Do not store them in screenshots or cloud notes. Verify addresses and transaction details before signing. Only approve connections and signatures from sites you trust. Comply with applicable laws in your jurisdiction. 4. No warranties The software is provided “as is” without warranties of merchantability, fitness for a particular purpose, or uninterrupted availability. Bitcoin network fees, congestion, and third-party indexers are outside our control. 5. Limitation of liability To the maximum extent permitted by law, KrayWallet authors and operators are not liable for lost keys, mistaken sends, phishing, malware on your device, or market losses. You use the software voluntarily. 6. Third-party services The wallet may call public explorers and kray.space APIs. Those services have their own terms. L2 bridge and marketplace rules are governed by kray.space documentation. 7.

Receive BTC to your Taproot address, or restore an existing BIP39 seed. Pin the extension; on mobile, open only from the home-screen icon after install. Social Space Social Space ( social.space ) is the public social network: inscription / L2 NFT profiles, follows, posts, likes, reposts, comments, and trending/recent feeds. Open the live feed at kray.space/social or from Social Profile in the mobile PWA. See Social Space . KrayChat (users) Messaging is end-to-end encrypted between wallet keys. Use it from the mobile app or extension chat flows. Sites that integrate chat must use the documented session APIs and never ask for your seed. L2 basics Deposit via the bridge, transfer/swap L2 tokens inside the wallet, withdraw back to L1 when needed. L2 operations are authorized by signatures you approve — see platform docs on kray.space for fees and bridge mechanics.

The mobile PWA does not expose this API — it is a standalone wallet client. Listen for krayWalletReady , then call requestAccounts() from a user gesture. On page load use getAccounts() (silent) — never auto-popup requestAccounts() on every refresh. Availability Chrome / Brave / Edge with KrayWallet extension installed.

Public API requestAccounts() Connect with popup (recommended for Connect button). const result = await window.krayWallet.requestAccounts(); // { address, ... } getAccounts() Silent session restore. Returns [] if revoked or locked out. const accounts = await window.krayWallet.getAccounts(); connect() Silent connect when already unlocked and approved. getPublicKey() x-only public key (hex).

May auto-sign non-sensitive messages while unlocked. Sensitive prefixes always force a popup. signMessageWithConfirmation(message) recommended Always opens the confirmation UI so the user sees exactly what they sign. Prefer this for payments, admin actions, and L2 auth. const { signature, address } = await window.krayWallet.signMessageWithConfirmation(message); Chat session activateChatSession() , encryptChatMessage(msg, theirPubKey) , decryptChatMessage(enc, theirPubKey) , isChatSessionActive() , clearChatSession() . getNetwork() / getActiveNetwork() Network helpers ( livenet , mainnet / kray-l2 ).
