The private bank for humans
and their AI agents.
Every transfer leaves your account encrypted and settles in 100ms blocks. Your agents hold their own accounts, pay natively over x402, and never spend a cent beyond the limits you set.
A new economic species
has arrived.
AI agents already earn, spend, and settle with each other around the clock. MansaFi is the private financial layer they run on: a non-custodial neobank where humans and agents transact confidentially, and every settlement is verified on Robinhood Chain.
Everything a private bank needs.
Nothing it shouldn't see.
One protocol for people and their agents. Every capability below is enforced by the chain, not by a policy document.
One account.
Two kinds of principals.
Human accounts and AI agent accounts live side by side on one protocol. Non-custodial, ZK-shielded, and governed by on-chain spending policies instead of server-side rules. Your money answers to you, not to a database.
Explore accounts →Confidential by default.
Auditable by choice.
Every amount is encrypted with ElGamal and proven correct by ZK range proofs: hidden from all observers, verifiable by anyone. When you choose to disclose, a view key reveals exactly what you want and nothing more.

AI agents that pay
for themselves.
Agent accounts resolve x402 payment requests natively, with no human in the loop. Spending policies are enforced on-chain, so an agent can never outspend its mandate, and MPP routing splits every payment for privacy.
Explore agents →Every transaction,
routed for privacy.
Multi-Path Payments split each transfer across parallel routes, so no observer ever sees the whole picture. Settlement stays atomic. Stealth addresses make every receipt unlinkable. Surveillance has nothing left to read.
Explore protocol →Selective disclosure.
Full verifiability.
Every transaction's existence is proven on-chain while amounts stay encrypted. Share a view key to give an auditor read-only access, with nothing exposed to the public and custody never leaving your hands.
Explore transparency →From sign-up to your first private transfer in three steps.
Open an account
Email and a passkey. Identity is verified once, keys are generated on your device, and nothing about your balances ever leaves it in plaintext.
Fund it with USDG
Deposit Global Dollar on Robinhood Chain or top up from a wallet. A small ETH reserve covers gas automatically so you never think about fees.
Send privately. Delegate to agents.
Pay any @handle with an encrypted amount, or spin up an agent account with a spend policy and let it pay for itself over x402.
Ship a private bank
in an afternoon.
A thin, typed SDK over a REST API. Accounts, confidential transfers, agent accounts with spend policies, and webhooks, all in one client.
import { MansaFi } from "@mansafi/sdk";
const bank = new MansaFi({ apiKey: process.env.MANSAFI_API_KEY });
// The amount is encrypted on-chain. The response confirms
// settlement but never echoes the amount in plaintext.
const transfer = await bank.transfers.create({
to: "@vendor",
amount: "125.00",
asset: "USDG",
memo: "Invoice #4471",
});
// Give an agent its own account and a hard budget.
const agent = await bank.agents.create({
handle: "datafetch",
policy: { dailyLimit: "50.00", maxPerRequest: "5.00" },
});
console.log(transfer.status, agent.address);Is MansaFi anonymous?
No, and deliberately so. Your identity is verified at account creation and your address is public on-chain. What stays private is the amount moving through your account: confidentiality, not anonymity.
Do I need to understand blockchain to use it?
No. You sign up with an email and a passkey, the same way you would set up Face ID for any app. Keys, encryption, and settlement are handled for you, invisibly and automatically.
How do agent accounts work?
Every agent gets its own smart account on Robinhood Chain and its own Agent ID under your parent account. It transacts under a spend policy you define: daily limits, allowed recipients, time windows, and an optional human approval threshold.
Can an agent spend beyond what I authorized?
No. Spend policy checks happen before a transaction is ever signed, not as a review after the fact. A policy-violating transaction is never even constructed.
What if I need to prove a payment to an auditor?
Share a view key. It grants read-only access to exactly the transfers you scope, nothing else, and you can revoke it at any time. Custody never leaves your hands.
What does it cost?
Nothing during beta. You pay only the underlying Robinhood Chain gas fee, typically a fraction of a cent, and even that is covered automatically from your ETH reserve.
