Privy Alternatives for Wallets: How Crossmint, Dynamic, Turnkey, and CDP Embedded Wallets compare in 2026

Key takeaways

• Privy is one of the most widely-adopted embedded wallet platforms, with a strong reputation for developer experience and consumer onboarding. For teams whose wallet needs are mostly about ease of onboarding and a familiar user experience, Privy remains a solid choice.
• Teams typically evaluate alternatives on two fronts: wallet architecture (smart contract wallets versus EOAs) or breadth of stack (whether onramps, offramps, payments, and compliance come on the same API). Privy was acquired by Stripe in June 2025, putting it inside a broader payments and stablecoin ecosystem alongside Bridge — a meaningful consideration for teams already evaluating Stripe's stack or weighing vendor concentration risk.
• The four credible alternatives in 2026 each take a different architectural approach: Crossmint (smart contract wallets as the default, with modular signers and support across EVM, Solana, and Stellar), Dynamic (acquired by Fireblocks in October 2025, MPC-based with unified embedded and external wallet support), Turnkey (non-custodial wallet and key management infrastructure spanning embedded wallets and company wallets), and CDP Embedded Wallets (Coinbase's developer wallet product, MPC-based with optional smart accounts on EVM).

EOA wallets vs. smart contract wallets

What kind of account holds your users' assets? There are two answers, and the difference shapes everything from security to portability.

An externally-owned account (EOA) is the original wallet model on most blockchains. It's defined by a single private key. Whoever holds the key controls the account, which means the key is both the wallet's identity and its only security mechanism. If the key is lost, the wallet is lost. If the key is compromised, the assets are gone. Modern embedded wallet providers, including Privy, harden this model by never exposing the full key to any single system. Privy splits the key into shards using Shamir's Secret Sharing, stores the shards in isolated hardware, and only reconstructs the key inside a Trusted Execution Environment (TEE) at the moment of signing. This is a real security improvement over a naked private key, and it preserves self-custody. The underlying wallet is still an EOA, so the security model is still tied to the integrity of the key and the infrastructure that manages it.

A smart contract wallet changes the account itself. Instead of a single private key controlling the wallet, the wallet is a smart contract deployed onchain, and the contract defines who can authorize transactions. The entities that authorize transactions are called signers, and a smart contract wallet can have one or more signers, with rules about which combinations are valid. Signers can be rotated, added, or revoked without moving the wallet or its assets. Spending limits, role-based approvals, session keys, and recovery rules can all be encoded directly into the contract. On EVM, the most common standard for this is ERC-4337. Equivalent smart contract wallet architectures exist across other major chains, including Solana (via program-derived addresses) and Stellar (via Soroban contracts).

The practical difference comes down to two things. First, key compromise: with an EOA, a compromised key is a drained wallet. With a smart contract wallet, a compromised signer can be rotated out and the wallet keeps working at the same address with the same balance. Second, vendor lock-in: with an EOA managed by a provider's hosted infrastructure, switching providers means migrating every user's assets to a new wallet. With a smart contract wallet and a modular signer layer, the wallet stays where it is and the signer is swapped underneath.

The platforms in this comparison split into two camps. Privy, Dynamic, Turnkey, and CDP Embedded Wallets all default to EOA-based architectures, with optional smart account features available on EVM. Crossmint defaults to smart contract wallets across EVM, Solana, and Stellar, with a signer layer that can be configured independently.

How Privy works

Privy is a wallet infrastructure platform used by teams spanning consumer apps, fintechs, banks, and AI agent products. Its core model is EOA-based: every user gets an externally-owned account, with the private key secured through a combination of Trusted Execution Environments (TEEs) and Shamir's Secret Sharing so that no single system, including Privy, ever holds the complete key. Authentication runs through familiar methods like email, social login, and passkeys, and users can export their key at any time.

Privy supports this model across EVM, Solana, Bitcoin, and Stellar. On EVM, Privy additionally offers ERC-4337 smart wallets, where the smart contract is controlled by a Privy embedded signer. This brings smart wallet features like gas sponsorship, transaction batching, and programmable permissions to EVM products, while still tying the signing layer to Privy's hosted infrastructure. Privy was acquired by Stripe in June 2025 and operates as a standalone product alongside Stripe's broader stablecoin stack, including Bridge.

Privy alternatives in 2026

Crossmint

Crossmint provides smart contract wallets as the default across EVM, Solana, and Stellar, with a modular signer layer that sits separately from the wallet itself. Teams can use Crossmint's native signers (covering end users via secure key enclaves and company or treasury wallets via AWS KMS, Azure Key Vault, and GCP HSM), connect an existing blockchain wallet, or plug in a third-party signing infrastructure including Privy or Dynamic. Because the wallet contract and the signer are decoupled, signers can be rotated without migrating assets or changing wallet addresses.

Crossmint's wallet infrastructure is purpose-built for AI agents. With Crossmint, the agent runs as a signer with its own key sealed in a TEE, and the smart contract enforces the spending caps, allowlists, and approval rules the agent has to operate within. The agent can transact autonomously, but only inside bounds the contract enforces. Crossmint also has native support for agentic payments protocols like x402, plus card network rails (Visa and Mastercard), so a single agent wallet can pay over stablecoins or cards depending on what the situation calls for.

Beyond the wallet, Crossmint covers onramps, offramps, stablecoin orchestration, and compliance tooling on the same API. KYC/KYB, AML screening, and travel rule compliance are built in. Crossmint holds MiCA CASP authorization for EU operations and is SOC 2 Type II certified. The combination of smart wallets, payments infrastructure, and built-in compliance is what makes Crossmint the default choice for fintechs, enterprises, and AI agent platforms operating at scale.

Dynamic

Dynamic provides embedded wallets where the private key is split between the user's device and a secure server environment, with both pieces required to sign transactions. The full key is never assembled — instead, the two sides cooperate cryptographically to produce a signature. This eliminates the single point of failure of a standard private key while keeping signing fast enough for consumer apps.

Dynamic supports authentication via email, SMS, social logins, and passkeys. The same wallet works across EVM, Solana, Bitcoin, Sui, TON, and Stellar. On EVM, embedded wallets can be turned into smart accounts with gas sponsorship and more advanced approval logic. Dynamic also offers a unified SDK that combines its embedded wallets with connections to existing external wallets, so the same SDK handles both flows. Dynamic's Global Wallet feature lets an app act as a login method that other apps can recognize through standards like WalletConnect, RainbowKit, and ConnectKit, which lets users carry the same wallet across multiple apps in an ecosystem.

Recovery options include passcodes, cloud backup, and developer-hosted backup independent of Dynamic. Wallets can be exported by the end user. Dynamic is SOC 2 Type II certified. Fireblocks acquired Dynamic in October 2025; Dynamic operates as its own brand within Fireblocks, with the combined platform positioning itself as a custody-to-consumer stack — Fireblocks institutional custody on the back end, Dynamic's wallet and authentication tools on the front end.

Turnkey

Turnkey is wallet and key management infrastructure. Where Privy, Dynamic, and CDP split or reassemble keys across multiple environments, Turnkey takes a different approach: keys live entirely inside hardware-isolated enclaves and never leave. They're generated, stored, and used for signing inside the enclave, and Turnkey's security model is independently verifiable — Turnkey publishes the source code that runs inside its secure environments, and third parties can confirm that what's running matches what's published. Signing latency is in the 50-100ms range.

The product surface spans three lines: Embedded Wallets (with variants for consumer apps, business teams, AI agents, and white-labeled wallet-as-a-service), Company Wallets for treasury operations and automation (including smart contract management and payment orchestration), and Key Management infrastructure (including enterprise disaster recovery and encryption key storage). Turnkey also serves as a signer for smart contract wallet providers, including as one of Crossmint's supported signing options.

Authentication accepts passkeys, email, SMS, OAuth, biometrics, and external wallets, with email-based recovery for lost wallets. The organization model lets developers structure access in detail — sub-accounts, scoped API keys, multi-party approval requirements, transaction limits, address allowlists, and time-bound sessions. Turnkey handles the full transaction lifecycle including construction, fee estimation, optional gas sponsorship, signing, and broadcast, and supports EVM, Solana, Bitcoin, TRON, and others through chain-agnostic signing. Onramps, offramps, stablecoin orchestration, and compliance tooling are integrated separately. Turnkey is SOC 2 Type II compliant.

CDP Embedded Wallets

CDP Embedded Wallets is Coinbase's developer wallet product — distinct from the consumer-facing Coinbase Smart Wallet that ships inside Coinbase's own apps. The product runs on MPC-based key management with private keys isolated inside Coinbase's secure enclaves. By default, users receive an EOA. On EVM, developers can opt into smart accounts, where the EOA acts as the signer for the smart contract wallet, unlocking gas sponsorship, transaction batching, and spend permissions that let apps and AI agents be granted scoped permission to use a user's funds within predefined guardrails.

Authentication methods include email, SMS, and Google login, with Apple login on the roadmap. Wallets are accessible across multiple devices per user. Chain support covers EVM-compatible chains and Solana. Smart account features are EVM-only; Solana wallets are EOA-based.

Policy controls include address allowlisting, transaction limits, function-level policies that restrict signing to specific contract calls, and risk-based screening for high-risk addresses. The wallet stack integrates tightly with the broader Coinbase Developer Platform — Coinbase Onramp, Coinbase DEX infrastructure, swaps, staking — and uses the same security infrastructure that powers Coinbase's internal accounts.

Which wallet infrastructure should I choose?

The right answer depends on what you're optimizing for.

‍If wallet portability and avoiding vendor lock-in are priorities. Crossmint. A smart contract wallet with a modular signer layer means the signer can be rotated, including to a different provider, without migrating assets. EOA-based platforms tie the wallet to the provider's signing infrastructure; switching providers means migrating users to new wallets at new addresses.

‍If you need smart wallet features on non-EVM chains. Crossmint. Privy, Dynamic, and CDP Embedded Wallets all offer smart account features on EVM but default to EOA on Solana, Stellar, and other chains. Crossmint's smart contract wallets run natively on EVM, Solana, and Stellar.

‍If your roadmap includes agentic payments. Crossmint. Smart contract wallets are table stakes for AI agents holding wallets and transacting under programmable policies, where spending limits and recipient allowlists are enforced by the contract rather than at the application layer. CDP Embedded Wallets has spend permissions that cover similar ground on EVM. Privy supports programmatic wallet creation that can be applied to agentic use cases, though the EOA architecture means agent policy enforcement happens at the key layer rather than onchain.

‍If your roadmap includes cross-app wallet identity in your ecosystem. Dynamic. Dynamic's Global Wallet lets your app act as a login method that other apps can use through standards like WalletConnect, RainbowKit, and ConnectKit, so users carry one wallet across an ecosystem of apps. For platforms or networks of products that want a shared wallet layer, this is a unique offering.

‍If you need deep tooling for internal company wallets, treasury operations, and onchain automation. Turnkey or Crossmint. Both ship dedicated treasury products. Turnkey's Company Wallets line includes smart contract management and payment orchestration as standalone products, which suits teams running treasury as a separate workstream. Crossmint's treasury wallets sit on the same platform as its end-user wallet and payments stack, with native enterprise signers like AWS KMS, Azure Key Vault, and GCP HSM — better for teams that want treasury, end-user wallets, and stablecoin payments under one provider.

‍If your product needs an all-in-one solution for wallets, onramps, offramps, payments, compliance. Crossmint. Onramps, offramps, stablecoin orchestration, KYC/KYB, AML, travel rule compliance, and MiCA CASP coverage are on the same API as the wallet. Privy, Dynamic, Turnkey, and CDP Embedded Wallets each cover the wallet layer; payments and compliance are assembled separately.

Strategies for using more than one

The platforms operate at different points in the stack and can coexist. Because Crossmint's smart contract wallets are signer-agnostic, teams using Privy, Dynamic, Turnkey, or CDP Embedded Wallets today can point a Crossmint smart contract wallet at any of those signing infrastructures, keeping the existing auth and signing stack while gaining onchain policy enforcement, signer flexibility, and the option to use Crossmint's payment infrastructure if needed.

FAQs

What is Privy used for?

Privy is embedded wallet infrastructure. It powers social login, key management, and wallet functionality inside applications, so users don't have to switch between an app and a separate wallet interface. Privy's default wallet is an EOA, secured with TEEs and Shamir's Secret Sharing. On EVM, Privy also offers ERC-4337 smart wallets controlled by a Privy embedded signer.

What is the best alternative to Privy for embedded wallets?

The best alternative depends on your priorities. Crossmint is strong for teams that want smart contract wallets as the default with integrated payment infrastructure. Dynamic suits teams building cross-app wallet identity in an ecosystem of products. Turnkey works well for teams that want dedicated tooling for internal company wallets and treasury automation. CDP Embedded Wallets is a fit for teams already building inside the Coinbase ecosystem.

What is the difference between an EOA and a smart contract wallet?

An EOA (externally-owned account) is controlled by a single private key; the key is the wallet's identity and its only security mechanism. A smart contract wallet is an onchain program that defines its own authorization logic, with signers that can be rotated, spending limits encoded in the contract, and multi-sig or role-based rules enforced onchain. Most wallet infrastructure platforms — Privy, Dynamic, Turnkey, and CDP Embedded Wallets — default to EOA-based wallets, with Privy offering ERC-4337 smart wallets on EVM as an upgrade. Crossmint defaults to smart contract wallets across EVM, Solana, and Stellar.

Is there a Privy alternative that includes stablecoin payments and wallets together?

Crossmint provides an integrated platform for smart wallet infrastructure, stablecoin orchestration, onramps, offramps, and compliance tooling on the same API. Privy, Dynamic, Turnkey, and CDP Embedded Wallets each focus on the wallet layer, with payment infrastructure handled by separate integrations.

Does Privy support AI agent wallets?

Privy supports programmatic wallet creation with policy enforcement applied at the key layer, which works for basic agentic use cases. The architectural limitation for AI agents is that there is no separate contract layer — policies live off-chain in Privy's backend rather than in the wallet itself. Spending limits, recipient allowlists, and approval rules are enforced by Privy's infrastructure, not by code that anyone can audit on-chain.

For AI agents, smart contract wallets are the stronger model because they separate the signer (who can authorize a transaction) from the wallet itself (what the wallet will allow). The contract layer encodes spending caps, role-based permissions, allowlists, and delegated approvals directly on-chain, where they execute deterministically and cannot be bypassed by the signer or the vendor.

Crossmint provides agent wallets built on this two-layer model: the agent runs as a signer with its own key sealed in a TEE, and the smart contract enforces the rules the agent has to operate within. The agent can transact autonomously, but only within bounds the contract enforces. Crossmint also has native support for agentic payments protocols like x402, plus card network rails (Visa, Mastercard) — so a single agent wallet can pay over stablecoins or cards depending on what the situation requires.

Can I use Privy and Crossmint together?

Yes. Crossmint's smart contract wallets can be configured with any signer, including Privy's. Teams using Privy for authentication and signing can run Crossmint smart wallets underneath to gain onchain policies, signer flexibility, and Crossmint's payment infrastructure without replacing their auth layer.

How do these platforms compare on compliance?

Privy, Dynamic, Turnkey, and CDP Embedded Wallets are SOC 2 certified and operate as non-custodial wallet infrastructure providers; KYC, AML, and regulatory compliance sit at the application layer for teams building on these platforms. Crossmint holds MiCA CASP authorization for EU operations, with KYC/KYB, AML screening, and travel rule compliance built into the platform.
