Etherspot

Ship Web3 flows that feel like Web2: sign in, act, done. With the Etherspot SDK, you give each user a programmable account the moment they arrive, no seed phrase required. Initialize the client, connect any signer you support (email, passkey, or EOA), and derive a deterministic smart account address that works across supported networks—even before it’s deployed. Let users receive assets, queue actions, or preview balances immediately. On the first interaction that needs it, the account is deployed automatically. You control when and how that happens, so onboarding screens stay clean and fast.

Build complex actions without complex UI. Compose multiple calls into a single atomic bundle: set allowance, swap, and send; mint and list; claim and stake. The SDK simulates the bundle so you can show outcomes, costs, and risks before execution. Cover fees on behalf of your users with the integrated relayer, and fall back to user-funded mode if you hit a spend cap. You can also choose who pays per action, giving power users full control while newcomers enjoy a fee-free path. Track progress via status events, surface tx hashes as they appear, and display a single progress bar for the entire bundle instead of juggling multiple popups.

Operate across chains without re-architecting. Point the SDK to the networks you need, route calls per action, and rely on the relayer to submit and monitor them. One codepath can handle minting on a sidechain while settling rewards on mainnet. Games can grant items on fast networks, then settle ownership or royalties elsewhere. Wallet builders can keep a unified history that merges actions from multiple networks. If a chain is congested, re-route or queue transparently and keep the session warm so users never lose context.

Take it from prototype to production quickly. Start on testnets, flip to mainnets with a single config change, and keep the same account addresses thanks to deterministic creation. Add feature flags for sponsored fees, set daily limits, and log every action for audits. Use session keys for time-bound gameplay or marketplace actions, and revoke them server-side at any time. Hook into webhooks or polling to update your UI instantly. Because keys stay with your users and accounts are smart by default, you can evolve your UX—add guardians, social recovery, or spending policies—without forcing a migration. The result: cleaner flows, fewer signatures, and a consistent experience across your entire product.
