Introducing the New Crossmint Wallet SDK

Wallet infrastructure is broken. 

Today, we're launching a new standard for Wallet SDKs, built from the ground up for stablecoins and fintech. No blockchain experience needed. No vendor lock-in. With first-in-class features included.

The Problem: Wallet SDKs Make Creation Easy, Everything Else Hard

Most SDKs make wallet creation easy. Everything after that? A nightmare.

Even a simple USDC transfer gets messy fast.

Want to sponsor gas, add staking, bridging, AML, or support new chains? Now you’re juggling multiple vendors — and your codebase explodes.

The Solution: Complex Operations, Single Lines of Code

Our new SDK condenses all that complexity into single lines of code. We handle everything under the hood from transaction construction to gas fees.

A simple transfer now looks like this:

That's it. Works on 50+ chains across EVM, Solana, Stellar, and more.

Advanced Features at Your Fingertips

But we didn't stop at basic transfers. More advanced features are just one line away:

• Staking: Earn yield without leaving your app
• Bridging: Move assets cross-chain seamlessly
• Compliance: Built-in KYC/AML screening 
• Commerce: Buy 1B+ real-world items directly

Toggle features on whenever you need them, on any chain.

Break Free from Vendor Lock-In

Most wallet providers lock you in. If their product falls short or regulations force you to switch, you’re in for a messy migration:

• Creating new wallets
• Transferring assets
• Updating addresses
• Disrupting users

Rotate The Signer Without the Chaos

Crossmint wallets are built on next-gen architecture.

Under the hood: smart contract wallets controlled by modular signers (TEEs, passkeys).

Need to switch providers? Just rotate the signer. No migration. No mess.

Permissions That Live Onchain

Most wallets store permissions off-chain in TEEs.Crossmint wallets store permissions inside the smart contract, allowing you to audit and verify the code. 

This allows you to add delegated signers and sophisticated policies, like giving permissions to an AI agent. 

Authentication Your Users Already Know

Critically for users, Crossmint wallets abstract all of the crypto complexity away. 

They can log in with an email or social account — using your auth or ours — and get a wallet that just works.

Built on Battle-Tested Infrastructure

Our wallets power one of the world's largest remittance firms, regulated financial institutions, and the next generation of fintech.

Built on open protocols securing tens of billions.
