The Problem

Sending money abroad is
still broken

💰

High fees

Traditional remittance providers charge 3-7% in fees and hidden FX markups and unfavorable FX markups, eating into every transfer.

Slow settlement

Wire transfers take 2-5 business days. Recipients wait, plans stall, and urgency goes unaddressed.

🔒

Crypto is complex

Existing crypto solutions require seed phrases, wallet installs, and blockchain knowledge. Non-starters for most families.

How It Works

Five steps. Under a minute.

1

Sign in with Google

MPC wallet created automatically. No seed phrases, no extensions.

2

Add funds via Stripe

Pay with credit/debit card. USDC deposited to your Solana wallet instantly.

3

Enter amount & recipient

Live FX rate locked at send time. Recipient identified by phone number.

4

USDC escrowed on Solana

Funds locked in an Anchor escrow program. Verifiable on-chain.

5

Recipient claims via SMS

Opens a link in any browser, enters UPI ID, receives INR. No app needed.

Every transfer is verifiable

Real escrow on Solana devnet

Platform Vision

Beyond remittances

The escrow primitive we built — time-locked, authority-gated, auto-refundable — is a building block for any transaction where two parties don't fully trust each other.

💼

Freelancer payments

Client locks USDC in escrow, releases on milestone delivery. Auto-refund if work isn't completed.

🛒

P2P marketplace

Buyer escrows payment, seller ships goods, funds released on confirmation. No chargebacks.

🎯

Bounty programs

Lock rewards in escrow. Claim authority releases to whoever completes the task. Transparent and verifiable.
