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.
| 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 | 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 | Non-custodial recovery codes on every chain, multi-device passkey approval, and opt-in hardware-isolated social recovery. | Provider-defined recovery and export options. |
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 deterministic self-custodial account is derived. Dynamic can also hide this, but its surface area is broader because it also serves crypto-native connection flows.
