Everything you need for secure stablecoin payments — nothing you don't.

Your Keys, Split Three Ways

Your private key is split into 3 encrypted shards. No single device or server ever holds the full key.

Pay with Your Card

Spin up virtual Visa cards instantly. Spend stablecoins at any merchant worldwide — they see a normal card payment, not a crypto wallet.

Biometric Authentication

Face ID and passkey support. Your wallet is protected by the same biometric security as your device — no passwords to remember or lose.

Shield Your Transactions

Zero-knowledge proofs (ZK-SNARKs) make your balance invisible on-chain. Nobody can trace your spending or total holdings. When compliance is needed, generate a Proof of Innocence — prove your funds are clean without revealing your history.

Give AI Agents a Budget

Set daily spending limits for autonomous AI agents. They pay for APIs, datasets, and cloud services via x402 micropayments — constrained by per-transaction caps you control. Payments above your threshold require biometric approval.

TrustCert Identity

Blockchain-verified credentials issued as Soulbound Tokens. Basic (ID), Verified (address), Enhanced (source of funds). Higher levels unlock larger limits and fiat off-ramps. Verifiable by third parties without exposing your personal data.

Virtual Visa Cards

Generate virtual Visa cards backed by your stablecoin balance. Add to Apple Pay or Google Pay. Merchants see a normal card payment — not a crypto wallet.

ZK Privacy Shield

Shield and unshield stablecoins with zero-knowledge proofs. Your on-chain balance becomes invisible. Generate Proof of Innocence for compliance without revealing history.

x402 Agent Payments

Give AI agents a spending allowance. Daily budgets, per-transaction caps, and biometric approval for over-limit requests. Your agents pay for APIs autonomously — within your rules.

Multi-Network

Base, Polygon, Arbitrum, Ethereum, and Solana. One wallet address for EVM chains, sub-cent fees across all networks. ERC-4337 means you never need ETH for gas.

FAQ

maphapay is a technology platform providing a user interface for services offered by independent third-party providers. maphapay does not offer, hold, or transmit funds, crypto-assets, or provide financial, custodial, or regulated services. All wallet functionality is non-custodial — private keys remain under exclusive user control. Financial services are provided by third-party licensed providers.

No. maphapay is fully non-custodial. Your private key is split into three encrypted shards using Shamir's Secret Sharing. One lives in your device's Secure Enclave, one in our HSM infrastructure, and one is an optional cloud backup. Any two of three are needed to sign — no single point of failure. A recovery phrase is generated at setup as an emergency backup. You are responsible for storing it securely.

maphapay uses zero-knowledge proofs (ZK-SNARKs) to shield your stablecoin balance from public view. Your transactions become unlinkable on-chain — nobody can trace your spending habits or total balance. When compliance is needed, generate a Proof of Innocence: a cryptographic certificate proving your funds are clean, without revealing your history.

No. maphapay uses ERC-4337 Account Abstraction so you never need to hold ETH. Gas fees are either sponsored or paid in the stablecoin you're spending. You think in dollars, not in gwei.

TrustCert is maphapay's identity verification system, issued as non-transferable Soulbound Tokens on-chain. Three tiers: Basic (email + phone), Verified (ID + address), Enhanced (full KYB + source of funds). Higher tiers unlock larger spending limits and fiat off-ramps. Certificates are verifiable by third parties without exposing your personal data.

Yes. maphapay supports three payment protocols: x402 (USDC micropayments), MPP (Stripe, Lightning, stablecoins), and AP2 mandates (Google's agent authorization). Agents pay for APIs, SMS, cloud services, and datasets autonomously — constrained by daily budgets and per-transaction caps that you control.

maphapay supports Base, Polygon, Arbitrum, Ethereum, and Solana. EVM networks share a single wallet address with sub-cent transaction fees. Solana offers the fastest settlement (~400ms). Switch networks anytime.
