Features
🏛️
KYC/AML Compliance Built-in
Crossmint provides integrated identity verification flows so agents operating in regulated contexts can onboard users with KYC/AML screening without building a compliance stack from scratch. Suitable for fintech, gaming, and enterprise use cases.
💳
Fiat On-ramp Integration
Built-in fiat-to-crypto on-ramp lets users fund agent wallets directly with credit card, ACH, or bank transfer. Agents can trigger on-ramp flows programmatically when wallet balance falls below a threshold.
🤖
Agent Identity Management
Each agent gets a persistent, addressable identity that can hold credentials, wallet addresses, and metadata. Supports linking multiple chains to a single agent identity for simplified cross-chain accounting.
🌐
Multi-chain Support (EVM + Solana)
A single Crossmint wallet API covers Ethereum, Polygon, Base, and Solana with a consistent interface. Smart wallets (ERC-4337) are available on EVM chains for gasless transactions.
