What is Dynamic?
Dynamic is a login and wallet SDK that combines authentication, embedded wallets and external wallet connections. It was acquired by Fireblocks in October 2025, per its pricing page. The free plan covers up to 1,000 monthly active users; 1,000 to 5,000 users cost $249 per month.
How Dynamic works
Dynamic's embedded wallets use threshold signature MPC.
The user holds one key share and Dynamic stores an encrypted server share. To sign, the user presents a JWT, Dynamic confirms identity, and the two shares produce a signature through an MPC relay using zero knowledge proofs, so the full private key is never assembled. Offline recovery can add a separate 2-of-2 pair: one encrypted share in the user's Google Drive and one delivered to your webhook, which can be combined locally without Dynamic.
Chain support comes in three tiers. Tier 1 covers all EVM networks, Solana, Bitcoin, Sui, TON, Stellar, Tempo and Arc, with gas abstraction and policies. Tier 2 gives raw signing with helper code for Aptos, Algorand, Cosmos SDK chains, Tron and Spark. Tier 3 is key derivation only, for chains such as NEAR, Cardano and XRP. External wallets connect through WalletConnect, ERC-6963, Mobile Wallet Protocol and the Solana and Bitcoin wallet standards.
How to start with Dynamic
- Create an environment ID in the Dynamic developer console.
- The current JavaScript SDK is headless, with no built-in modal, so you build the login UI yourself; the React quickstart needs Node.js 18+ and a Vite React app and defaults to email OTP with an EVM embedded wallet.
- A user counts toward your MAU total when they log in at least once that month or when an embedded wallet, including a pre-generated one, is created for them.
- Dynamic's services are unavailable in Cuba, Iran, North Korea, Syria and the Crimea, Donetsk and Luhansk regions.
Dynamic fees and limits
- From 1,000 to 5,000 MAUs the price is $249 per month, and each MAU above 5,000 adds $0.05.
Self-serve is free up to 1,000 monthly active users, with support through the community Slack and rate limits. Enterprise pricing is custom and adds bring-your-own auth, SSO, webhooks, gasless transactions, business accounts and dedicated support. Native gas sponsorship covers Ethereum, Base, Optimism, Arbitrum One, BNB Smart Chain, Robinhood Chain, Arc and Solana, plus testnets such as Ethereum Sepolia, Base Sepolia and Solana Devnet; the docs tell you to contact Dynamic if it is not on your plan. Sponsorship is switched on per environment with the evmGasSponsorshipEnabled and svmGasSponsorshipEnabled settings.
Risks to know before using Dynamic
- Normal signing combines the user's share with Dynamic's server share through its MPC relay; offline recovery is the documented path for rebuilding a wallet while Dynamic is offline.
- When offline recovery is on, users cannot also use Google Drive as a regular cloud backup.
- Sanctions screening runs on every wallet that signs in and cannot be turned off, though you can supply your own Chainalysis or TRM Labs key.
- Dynamic says it is SOC 2 Type II compliant, runs a bug bounty and uses TEEs alongside TSS-MPC.
