Chainwallet

Self-custody crypto, calmer. Read-only, on-device.

Every feature, from the first launch.

No account, no login, no cloud. Everything runs on your device and works fully offline — nothing in this post is hidden behind a wall.

What Chainwallet does

Chainwallet is a read-only watchlist + portfolio tool for self-custody crypto users. You add your public addresses (never your seed). The app shows balances, classifies tokens as legit / unknown / known-scam from a bundled registry, and helps you keep a tax-event log so your accountant doesn't hate you.

What's in v1:

— Address book: add EVM, Solana, Bitcoin public addresses (read-only, no keys). Label each one ("trading wallet," "savings cold storage," "NFT wallet"). — Portfolio view: aggregated USD value across addresses (refreshed on demand only — no background polling). Per-chain breakdown. — Scam-token registry: ~400 known-scam token contracts bundled in the app (sourced from open chain-of-trust lists curated by GoPlus, Phantom's public scam registry, OFAC sanctioned addresses). Each token in your wallet is checked locally against the registry. No address transmission to a server. — Tax-event log: manual entry for buys, sells, swaps, and stables. Generates a year-end CSV for TurboTax / Koinly / your accountant. — Risk checklist: 12-item self-audit (seed phrase backed up? hardware wallet? trezor firmware updated? exchange not your wallet? token approvals revoked?). The basics every retail user keeps forgetting. — No active actions: Chainwallet can't sign a transaction. It can't move funds. It's a watch.

Free. Chainwallet Pro ($19.99/yr) adds: Apple TV airdrop-safe view ("show me my balance, don't show what's in it"), CSV export of the tax log, and the specialty multi-chain price ticker.

Why we built it

20M+ self-custody users globally (Chainalysis). Existing wallets (MetaMask, Phantom) are transactional — they're for sending, not for surveying. Existing watchers (Zerion, Zapper) require account creation and transmit your addresses. The on-device, read-only, scam-aware tool doesn't exist.

What makes it different

Chainwallet is the only iOS crypto app where: (a) no keys are ever entered, (b) addresses never leave the phone (balance + token lookups happen via user-tappable web links, not embedded API calls in v1), (c) the scam registry is bundled, fast, offline. Zerion and Zapper require accounts. Phantom and MetaMask are walle…

Who it's for

Freelancers, contractors, and small-business owners who want their numbers right at tax time without renting a SaaS to do it.

In one line: Self-custody crypto, calmer. Read-only, on-device.
