Self-custodial · From the LongPay family

Your keys.
Your crypto.

A self-custodial wallet for Bitcoin, Ethereum and Tron — plus USDT and USDC. And the easiest way to pay: type a merchant's LongPay @handle, the wallet fetches and verifies the address, you approve. No copy-paste, no mistakes.

The LongPay integration

Pay by @handle. No addresses, no mistakes.

Every LongPay merchant with a public @handle can be paid straight from the wallet. Type the @handle and an amount in HK$ — the wallet asks LongPay for the exact payout address and quote, checks both against the network you chose, and shows you everything before anything is signed.

01

Type the @handle

No QR hunting, no address copy-paste. Enter the amount in HK$ — the same number the till shows.

02

The wallet verifies

It fetches the payout address from LongPay, validates it for the right network and currency, and displays it in full. The wallet never signs on its own.

03

Approve — done

You send exactly the quoted amount, so the merchant's LongPay matches the payment instantly. Confirmed with your password or biometrics.

Everything a daily wallet needs

A full wallet, not a demo.

Send, receive and track three chains and two stablecoins — with the conveniences you actually use every day, in HK$ first.

Three chains, two stablecoins

BTC, ETH and TRX, plus USDT on Ethereum and Tron and USDC on Ethereum. Balances and history in one portfolio.

HKD-first, live

Enter amounts in HK$ like a normal payment. Live prices, 24-hour change and 7-day sparklines — or hide balances with one tap.

Spend gate

Every send asks for your password or biometrics again — even while unlocked. A stolen unlocked phone still can't spend.

Encrypted backup

One .lpbackup file, encrypted with your password — safe to keep in iCloud or Drive. Your raw 12 words never touch the cloud.

Ledger ready

Sign with a Ledger hardware wallet over WebHID on desktop web and the extension — keys stay on the device you trust.

Accounts & watch-only

Multiple accounts from one seed — same derivations as MetaMask, TronLink and Ledger Live — plus watch-only tracking of addresses you don't hold.

Bitcoin done right

A fresh receive address whenever you want, balances across all of them, and one-tap “speed up” (RBF) for a stuck transaction.

Scan anything

BIP-21, EIP-681 and TRON payment QR codes fill the send form automatically — and your receive QR can request an exact amount.

Yours, everywhere

English, Français and 中文. Night and paper themes. Contacts with a first-send warning. Biometric unlock on the Android app.

Self-custody, done carefully

Security is the product.

A wallet's only real job is to keep your keys yours. Everything in LongPay Wallet is built around that.

Keys never leave your device

A standard 12-word phrase, generated locally and encrypted with scrypt + AES-256-GCM under your password. LongPay never sees it — nobody does.

Verified payouts

@handle payments validate the returned address for the exact network and currency, and show it before you approve. Even a hostile network can't silently redirect funds.

Nothing to fake

A fixed allowlist of six assets. Unknown tokens are refused, never guessed — so a scam token can't dress up as money in your portfolio.

Proven, not promised

85 offline cryptography checks against official test vectors plus end-to-end tests on web, extension and Android — all green before any release. Hardened in an August 2026 security audit.

No trackers, no analytics Self-hosted fonts, strict CSP Talks only to chain nodes, prices & LongPay Auto-lock + spend gate on by default
