Free user allowances on wallet SDKs run from 500 monthly active users on Privy to 1,000 on Dynamic, Web3Auth, thirdweb and Crossmint. Past that, costs diverge fast: Web3Auth's next plan is $69 a month, Dynamic's $249 and Privy's $299. This list ranks seven wallet SDKs on those published numbers and on the wallet types they support.

Quick answer

Privy is the best wallet SDK for consumer apps that want email or social login with an embedded wallet, backed by Stripe. Choose Web3Auth for the cheapest paid tier ($69 a month) and Dynamic if many users bring their own wallets.

01Privy: best for consumer apps
02Dynamic: Best mixed wallet support
03MetaMask Embedded Wallets: Best low-cost paid plan
04thirdweb: Best with gas sponsorship
05Crossmint: best for stablecoin apps

How to choose

Model MAU costs

At 3,000 monthly users, Web3Auth costs $69 a month, Dynamic $249 and Privy $499 on Scale (2,500 to 9,999 MAU). Recheck at your expected size.

Embedded, external or both

New users need an embedded wallet. Existing crypto users want to connect their own. Dynamic covers both; Privy, Web3Auth and thirdweb pair well with WalletConnect.

Plan for key export

Ask how users can export keys if you switch providers later. Moving users between SDKs is the hardest part of changing vendors.

Businesses holding client funds

If you are a bank or fintech, Dfns lists SOC 2 and ISO 27001 reports and HSM key options.

Bottom line

Add WalletConnect alongside any embedded wallet SDK so existing wallets can connect.

FAQ

What is an embedded wallet?

A wallet created inside your app when a user signs in with email or a social account, so the user does not need to install a wallet first.

Which wallet SDK is free for the most users?

Dynamic, Web3Auth, thirdweb and Crossmint each list 1,000 free monthly users or wallets. Privy and WalletConnect's Reown Starter list 500.

Is Web3Auth still available?

Yes. Its pricing page says it was acquired by Consensys and still lists Base, Growth, Scale and Enterprise plans.

Privy or Dynamic?

Privy suits apps whose users sign in with email; Dynamic suits apps where many users connect an existing wallet, with 800+ supported.

Are these wallets self-custody?

The SDKs are built so the app does not hold full keys, but the exact model differs. Read each provider's security docs before you launch.
