Crypto has a receiving problem. Not a sending problem, not a scaling problem — a receiving problem. If someone wants to pay you in Bitcoin, Ethereum, or Solana right now, you need to already have a wallet, already know your address, and already understand which chain the sender is using. That's three barriers before a single cent moves.
The custody trap
The industry's answer has been custody. Coinbase, Binance, Cash App — they hold your keys so you don't have to think about them. It works, until it doesn't. Exchanges freeze accounts. They get hacked. They go bankrupt. And the moment you hand over your keys, you've traded the entire point of crypto for convenience.
The alternative — self-custody — asks users to write down 24 words, understand wallet software, and never lose a piece of paper. That's not a solution for normal people. It's a solution for people who were already going to figure it out.
What if you didn't have to choose?
nimimo exists because we believe the choice between custody and complexity is false. You can have keys generated and encrypted on your device, invisible to the server — and still sign up with just an email.
Your keys are created in your browser using the same security standards that protect online banking. They're encrypted and stored on your device, never transmitted. The server knows your name and your public addresses. It has zero ability to touch your funds.
One name, three chains
When you sign up for nimimo, you get a human-readable handle like @lucky-mountain. That handle works for Bitcoin, Ethereum, and Solana. Someone can send you ETH by going to nimimo.com/@lucky-mountain — no wallet app required on their end, no address copying, no chain selection.
This is the part that matters most. Crypto becomes receivable by anyone with a link. Share it in a bio, text it to a friend, print it on a business card. The name is the interface. The blockchain is the backend.
Recovery without custody
The hardest problem in non-custodial design is recovery. If the server doesn't have your keys, how do you get them back when you lose your phone?
nimimo's answer is a recovery card — a PDF containing a QR code and a PIN. The QR holds your encrypted wallet data. You can print it, split the QR from the PIN, store them separately. To restore, scan the QR and enter the PIN on any device. No cloud. No sync service. No trust required.
And you verify it works before you need it. nimimo won't just let you download a backup and hope — it asks you to prove the backup actually restores.
What we're building toward
nimimo is not trying to replace wallets. It's not a DEX, not a DeFi protocol, not a token. It's an identity layer — a way to make crypto receivable by people who don't yet have a wallet, recoverable by people who don't want to manage seed phrases, and usable by people who just want to get paid.
The server is a directory. The client is the vault. The user is the owner. That's the architecture. Everything else follows from it.
