Circle Wallets helps you add secure, embedded to your application so your users can hold and use digital assets without the usual complexity of keys, infrastructure, and chain-specific details. You integrate using REST APIs or Web and Mobile SDKs (Android and iOS).Documentation Index

Key features
Circle Wallets gives you the building blocks to ship embedded wallets without running key infrastructure or blockchain nodes yourself.Key storage and signing
Key storage and signing
You don’t manage raw private keys. Circle secures keys with MPC or passkeys
depending on wallet product; you get APIs to create wallets, sign
transactions, and authorize actions. Key backup, rotation, and recovery are
built in so you can focus on your app logic.
Unified APIs and SDKs
Unified APIs and SDKs
One integration surface for REST APIs and Web or Mobile SDKs (Android and
iOS). Create wallets, send transfers, and run contract calls from your
backend or client. Same patterns across developer-controlled,
user-controlled, and modular wallets based on the supported feature set for
each product.
Managed blockchain infrastructure
Managed blockchain infrastructure
Circle handles broadcasting, indexing, and balance and event data for
supported chains. You don’t run or maintain nodes. For chains where full
infrastructure is not offered, use Signing APIs with your own node.
Multi-chain and token support
Multi-chain and token support
Support for multiple chains and token types (including ERC-20, ERC-721,
ERC-1155 on EVM and SPL on Solana). Unified addressing on EVM so one wallet
can share the same address across chains. See Supported
blockchains and Monitored
tokens for details.
Products
Developer-controlled wallets
You create and operate wallets for your users. Best when you need to move
funds or run actions on their behalf (for example, payouts or automation).
User-controlled wallets
Your users control their own wallets inside your app, with familiar sign-in
(social, email, or PIN). Best when users should own and approve every
transaction.
Modular wallets
Your users control their wallets with passkeys and optional modules, like
gasless. Best when you need passkey-based custody and flexible account
configuration.
Gas Station
Sponsor network fees so your users don’t need to hold native tokens. Set
policies and pay gas with your credit card.
Paymaster
Let users pay gas fees with USDC instead of native tokens using Circle’s
permissionless ERC-4337 paymaster contracts.
Compliance Engine
Automate transaction screening for AML and CTF compliance. Define rules,
manage allowlists and blocklists, and review alerts.
Get started
The right wallet product depends on who controls the wallet:| Custody model | Best for | Product |
|---|---|---|
| You control the wallet | Payouts, automation, backend-initiated actions | Developer-controlled wallets |
| Your users control the wallet with familiar sign-in | Consumer apps where users approve transactions | User-controlled wallets |
| Your users control the wallet with passkeys | Apps requiring phishing-resistant auth and account modules | Modular wallets |
