Minting API
It takes months to build secure and reliable minting infrastructure:
  1. Write and maintain token smart contracts
  2. Build a backend for orchestrating all blockchain transactions
  3. Securely administer keys and crypto balances
  4. Add queueing, batching, RPC redundancy, priority/gas fee estimations, e2e observability…
Crossmint manages all of this for you via a suite of APIs to create, update, delete and manage tokens of any type through REST APIs, available on any chain.

FAQs

No, you can migrate providers anytime, transfering ownership of the smart contracts to an external wallet.
Yes, you can transfer ownership at any time. However, note that Crossmint APIs (eg. minting, editing NFTs) may stop working on that contract unless you whitelist Crossmint on the contract to continue executing those actions. If you transfer ownership of the contract to your own wallet, you are responsible for ensuring the security of that wallet.
When you create an account, Crossmint automatically creates a gas station to manage network fees on your behalf. You will be billed in fiat and Crossmint will ensure you never run out of funds to support customer operations. This eliminates the need to build a cryptoaccounting system, execute recurring and expensive crypto purchases, holding the FX risk, and automating treasury operations.
When you create an account, Crossmint will automatically create a dedicated MPC vault to secure your token contracts which you can manage via API. You get one vault per , in case you are working with multiple teams. You can of the contracts to an external wallet at any time.
