Internet Computer wallet
Send ICP by username, not a 63-character address
ICPay is an open-source custodial wallet on the Internet Computer. Claim a handle, receive payments from anyone, and explore channels, on-chain storage, and Motoko tooling from one ecosystem.
Sign options via Internet Identity
Platform
Built for everyday users and ICP developers
ICPay is more than a wallet. It is the entry point to payments, community, storage, and canister development on the Internet Computer.
Claim a handle and share icpay.app/yourname. Senders do not need an account or a 63-character principal.
Sign in with a passkey or linked account. No seed phrase to write down and no browser extension required.
Telegram-style broadcast communities with public discovery, private invites, and markdown posts.
On-chain file storage with API keys and SDKs. Pay in ICP with simple 30-day plans instead of a card bill.
Production Motoko scaffolding with enforced layering, tests, and a global CLI for Internet Computer apps.
Funds sit in per-user subaccounts on the official ICP ledger. The backend is open source and upgrade-only on mainnet.

How it works
How difficult is it to use?
Not very. Six steps from Internet Identity sign-in to sending ICP by username — no browser extension and no mnemonic to write down.
Use a passkey or linked account. No password notebook and no seed phrase to lose.
Pick a handle once. People pay you at icpay.app/yourname instead of a 63-character principal.
Send your username page or deposit address to anyone who needs to pay you in ICP.
Transfer ICP in seconds. Type a handle, confirm the amount, and the ledger records it on-chain.
Balances and history tie to the official ICP ledger. Open any transaction on the block explorer.
Channels for community, ICBucket for on-chain files, and ICFalcon for Motoko development — same ecosystem.
Social proof
Can I trust it?
ICPay is custodial and has not been audited — we say that plainly. What you can verify today is the open-source code, the mainnet canister, and the published transparency policy.
Backend Motoko and the Next.js frontend are public. Inspect fund movement, auth, and upgrade paths yourself.

Canisters
Every transaction, user balance, and decentralized service runs on verifiable Internet Computer canisters under global consensus.
Canister Security Architecture
Consensus
Subnet Replicated
Threshold ECDSA and Byzantine fault tolerant consensus across decentralized nodes.
Custody
Isolated Subaccounts
Each user funds are locked in personal subaccounts; never commingled in pooled hot wallets.
Bytecode
Verifiable WASM
Canister builds produce provable bytecode hashes matching the open-source repository.
Identity
