Crossmint Knowledge

Products

Smart Wallets

Non-custodial wallets that users control via email, phone, passkeys, or social login. No seed phrases. Crossmint never has access to user funds.

• Use case: Any app that wants to give users a wallet without the UX friction
• Chains: EVM (Ethereum, Polygon, Base, etc.), Solana, Stellar
• Key feature: Users can recover wallets via their email/phone — no seed phrase backup needed

Checkout

Accept payments for anything — physical goods, digital items, NFTs, tokens — via credit card, Apple Pay, Google Pay, or crypto.

• Use case: Selling NFTs, accepting crypto payments, e-commerce with crypto option
• Key feature: Automatic currency conversion, fraud protection, global coverage

Minting API

Create NFT collections and mint tokens programmatically. No smart contract deployment needed.

• Use case: Loyalty programs, ticketing, digital collectibles, credentials
• Key feature: Crossmint handles contract deployment, metadata hosting, and gas

Stablecoin Orchestration

Move USDC and other stablecoins globally with built-in compliance (KYC, AML, sanctions screening, travel rule).

• Use case: Cross-border payments, treasury management, payroll
• Key feature: Compliance is automatic — Crossmint blocks non-compliant transfers

AI Agent Commerce

Infrastructure for AI agents to make purchases on behalf of users. Agents can access delegated payment methods and buy from Amazon, Shopify, or any e-commerce site.

• Use case: AI assistants that can shop for users
• Key feature: Users delegate payment authority; agents handle the rest

Verifiable Credentials

Issue tamper-proof digital credentials (diplomas, certifications, memberships) as NFTs.

• Use case: Education, professional certifications, membership programs
• Key feature: Credentials are verifiable on-chain but human-readable

Supported Chains

How Crossmint Compares

Key Concepts

Wallet Locators

Crossmint uses "locators" to reference wallets flexibly:

• email:[email protected] — wallet linked to email
• phone:+1234567890 — wallet linked to phone
• userId:abc123 — wallet linked to your app's user ID
• 0x... — direct wallet address

Environments

• Staging: For testing with testnets (free, no real money)
• Production: For mainnet (requires business verification)

Gas Sponsorship

Crossmint pays gas fees on behalf of users. Developers don't need to manage gas tokens or worry about fee estimation.

Custodial vs Non-Custodial

• Custodial: Crossmint holds keys (simpler, but Crossmint has access)
• Non-custodial (Smart Wallets): User controls keys via MPC — Crossmint never has full access

Common Questions

Q: Does Crossmint charge gas fees to developers?
A: No. Gas is included in Crossmint's pricing. Users and developers don't manage gas.

Q: Can users export their wallet to MetaMask?
A: Smart Wallets are non-custodial but use MPC, so there's no single private key to export. Users control their wallet via their auth method (email, passkey, etc.).

Q: What's the pricing model?
A: Usage-based. Free tier available. Paid plans based on API calls, transactions, and features.

Q: Is Crossmint compliant for money transmission?
A: For stablecoin orchestration, Crossmint partners with licensed entities and handles compliance (KYC/AML/travel rule) automatically.

Q: Which chains should I use?
A: Base or Polygon for low-cost EVM. Solana for high-throughput. Stellar for stablecoin-focused use cases.
