This page is Dynamic vs Cavos, not Privy vs Dynamic. Privy vs Dynamic is provision versus connect between two finished SDKs; see Privy vs Dynamic. For a multi-vendor shortlist, see Dynamic alternatives. Dynamic provides wallet connection, embedded wallets, and authentication tooling with a strong emphasis on multi-wallet login experiences and developer-facing configuration.
Dynamic is strongest as a unified login and wallet-connection layer covering many wallets and chains. Cavos is narrower and more opinionated: one device-native, self-custodial account model implemented natively per chain, currently Starknet, Solana, and Stellar.
For the category itself (custody, key models, and what the SDK actually does) start with embedded wallets and the embedded wallet SDK. The embedded wallet guide is that page. The named-vendor table is embedded wallet providers. Platform parts and pricing models are in wallet-as-a-service. The method-level surface is the embedded wallet API. The React install is how to add an embedded wallet.
| Capability | Cavos | Dynamic |
|---|---|---|
| Primary focus | Embedded, device-native self-custodial accounts. | Wallet connection and authentication across many wallets, plus embedded wallets. |
| Signing authority | Self-custodial. A non-exportable device key is the signing authority; Cavos holds no key that can move user funds and uses no MPC shares. | Embedded wallet keys managed by the provider’s key infrastructure with configurable custody models. |
| Chain coverage | One SDK with chain-native adapters. Starknet, Solana, and Stellar available today. | Multi-chain, with EVM breadth and additional non-EVM support; parity varies by chain. |
| External wallet connection | Not a goal; Cavos provisions the wallet rather than connecting to existing ones. | Core capability with broad wallet coverage. |
| Gas sponsorship | Gas Sponsorship in Any Token. Chain-specific: Starknet paymaster, Solana relayer as fee payer, Stellar sponsored reserves and fee bumps. | Supported through account abstraction and paymaster integrations, mainly on EVM. |
| Recovery | Passkey restore on a new device and opt-in hardware-isolated social recovery, both non-custodial. | Provider-defined recovery and export options. |
| Pricing | Free up to 1,000 wallets. Essential $59/mo. Complete $139/mo. | $249/mo for up to 5,000 MAUs. Then $0.05 per extra MAU. Sandbox is free. |
Dynamic vs Cavos is a one-to-one comparison of two embedded wallet products. Dynamic is strongest as a unified login and wallet-connection layer covering many wallets and chains, plus embedded wallets. Cavos provisions a device-native, self-custodial account on Starknet, Solana, and Stellar and does not connect wallets users already hold. They are not drop-in replacements. Privy vs Dynamic is a different page.
No. Cavos provisions and controls an embedded, device-native account for each user. If connecting existing external wallets is a requirement, a connection-focused provider such as Dynamic is the better fit, and the two models can coexist in one product.
Cavos is designed so a user never selects a wallet: they sign in with an identity you already own and a self-custodial account is resolved (the first device to claim names the address). Dynamic can also hide this, but its surface area is broader because it also serves crypto-native connection flows.
Cavos is free up to 1,000 wallets, then Essential at $59/mo and Complete at $139/mo. Dynamic lists $249/mo for up to 5,000 MAUs, then $0.05 per extra MAU, with a free sandbox.
Cavos ships one SDK with chain-native adapters for Starknet, Solana, and Stellar. Dynamic is multi-chain, with EVM breadth and additional non-EVM support; parity varies by chain.
They sit at different layers. Dynamic is strongest as a unified login and wallet-connection layer that also ships embedded wallets (TSS-MPC; public docs list native chains including EVM, Solana, Bitcoin, Sui, TON, Stellar, Tempo, and Arc). Web3Auth / MetaMask Embedded Wallets is a social-login MPC wallet layer with broad multi-chain coverage and key export. Dynamic vs Web3Auth is usually connect-and-configure versus social-login chain coverage. Cavos is neither: three native adapters and a device-native key.
