What is Crossmint?
Crossmint is a developer platform for embedded and treasury wallets, stablecoin on-ramps, off-ramps, payouts and token minting. Its pricing page lists 1,000 free monthly active wallets, wallets from $0.02 per monthly active wallet after that, and regulated transfers across 50+ blockchains.
How Crossmint works
Crossmint wallets are smart contract wallets created and operated through one API, with SDKs for React, React Native, Flutter, Swift, Kotlin and Node.js.
Custody is decided by the signers you attach, not by Crossmint. A non-custodial setup pairs a device signer generated in the user's secure enclave with email or phone OTP recovery. A custodial setup uses server signers or Cloud KMS keys held in your backend. Hybrid setups split signing authority between you and the user, and passkeys, HSMs and external wallets can also act as signers.
A wallet counts as active in any month it appears in an API request, including creation, address lookups, balance reads, signing or transfers. Gas sponsorship lets Crossmint pay network fees from a treasury and bill you in fiat. For Solana smart wallets it is on by default in staging but off for new production projects until you ask sales to enable it; otherwise the executing wallet pays in SOL or USDC. For stablecoin orchestration, the pricing page lists Crossmint's licensed infrastructure, transaction monitoring and travel rule checks.
How to start with Crossmint
- Open a developer account in the staging console, create a client API key and install @crossmint/client-sdk-react-ui.
- With Crossmint Auth in the providers, a wallet is created on login and wallet.stagingFund() adds test USDXM.
- Going live means a separate production account, a production key with scopes such as wallets.create and wallets:transactions.sign, mainnet chains (base-sepolia becomes base) and re-created wallets, because staging addresses do not carry over.
- Crossmint recommends Auth0, Firebase or Supabase instead of its own auth in production.
- For funding, the onramp lists coverage of 160+ countries and all US states, including New York, with debit and credit cards, Apple Pay, Google Pay and bank transfers.
- The same page lists chargeback protection and KYC data sharing by API as onramp features.
- If you sell tokens instead, the checkout accepts debit and credit cards, ACH, Apple Pay, Google Pay and crypto, including cross-chain payments.
Crossmint fees and limits
- The developer plan includes 1,000 monthly active wallets, up to 2,000 transactions and up to $50 of gas sponsorship.
- Above that, the pricing page gives two figures: a headline overage from $0.025 per MAU and a comparison table starting at $0.02 per monthly active wallet, with volume discounts.
- Tokenization starts at $0.01 per action, metadata uploads cost $0.002 each with 10 MB per token, and the developer tier is limited to 100 tokenization actions per hour.
Onramp, offramp and checkout fees are charged per transaction and are usually paid by your end user as a convenience fee, which you can choose to subsidize. Crossmint says rates depend on card type, geography, currency, blockchain and volume commitment, and the pricing page lists no rates. Its FAQ offers bundle packages with discounted unit rates if you use several products.
Risks to know before using Crossmint
- Your signer choice sets your legal position.
- If you hold server signers or Cloud KMS keys, your organization is the custodian, and Crossmint's own custody page notes that custodial providers can face licensing duties and liability if a wallet is compromised.
- Per-user spending limits on gas sponsorship are private access only, so you have to watch sponsored spend in the Console or through wallets.transfer.out webhooks.
- Regulatory status per the pricing page footer: Crossmint Financial Services US is registered with FinCEN as a money services business, Crossmint Europe S.L. is authorised by Spain's CNMV as a MiCA crypto-asset service provider and by the Bank of Spain under PSD2, and Crossmint Canada is registered with FINTRAC.
- Services that need no authorization, such as non-custodial wallets, come from Crossmint Inc.
