Private payments · by handle · on Solana
Monyr turns your handle into a payment profile. Share one link in a bio, a newsletter, an invoice, a QR — no wallet addresses to copy, no public ledger to scan. Just USDC, landing in a vault only you can decrypt.
Non-custodial. One signature to claim. Live onSolana devnet — your wallet history, your balance, and your memos stay off the public ledger.
Hand a client your address and you’ve handed them every payment, every flip, every relationship — to anyone with a browser. Same person, same payments, two very different stories.

Tip jar, per-client label, invoice, product. The path after your handle is just metadata — every variant lands in the same private vault.

Pay any amount. The link you put in every bio.
monyr.xyz/@alice/acme
Acme sees Acme. You see /acme grouped in your inbox.

Locked amount, optional expiry. Marks itself paid.
monyr.xyz/@alice/product/mini-zine
Fixed price, gated unlock. Downloads, licenses, or access passes.
Non-custodial by design. Your main wallet signs once; a fresh keypair (the vault) is generated in your browser and never leaves it unencrypted. Payments arrive there.

Phantom, Solflare, Backpack. Anything that speaks Wallet Standard.
Pick your handle, sign once
One signature derives an encryption key in your browser. That key locks a fresh vault only you can open.
Share your link
Drop monyr.xyz/@yourname into a bio, an invoice, a QR. Payments land in the vault encrypted.
Curious about the cryptography — vault encryption, the mixer, viewing keys for your accountant? It’s in the FAQ below.
No. Your handle resolves to a separate keypair generated in your browser at signup. Your main wallet only signs the unlock message — the two never share a transaction. Withdrawals route through Umbra’s mixer, so the chain doesn’t draw a line from your handle to your destination wallet.
Non-custodial. The vault’s secret is encrypted in your browser with AES-256-GCM under a key derived from your wallet signature. The server stores ciphertext we cannot decrypt. No email, no KYC.
Only what you scope. Issue a viewing key for Q1 2026 and your accountant decrypts amounts in that window — counterparties stay opaque, and they can never move funds. The grant is revocable on-chain.
Download the encrypted vault blob and store it like a seed phrase, or opt in to a passphrase as a second unlock factor — recover without the wallet.
§ 05 · Claim
Short handles run out the way short usernames always do. Be early, or be lowercase-with-numbers.
One signature. Non-custodial. No email, no KYC.
