Passkey onboarding and intent execution for Stellar apps

Passkey smart accounts, scoped sessions, sponsor relay, intent execution, and a React UI kit — packaged so apps embed the flow instead of rebuilding it.

What Lazee Kit ships

Focused primitives, packaged as one reusable kit

Lazee Kit is a passkey onboarding and intent execution toolkit for Stellar apps. It is an embeddable developer layer — not a standalone wallet.

Passkey smart accounts

Soroban contract accounts users create with FaceID or TouchID — no seed phrase and no upfront XLM.

Scoped sessions

Agents and apps get a limited grant — allowed assets, contracts, caps, and expiry — never the user's keys.

Sponsor relay

Simulates, fee-sponsors, submits, and tracks transactions with per-app budgets and abuse controls.

Intent execution

Users describe an outcome — send, swap, bridge in, gift, claim, DCA — and Lazee turns it into a transaction plan.

React UI kit

Drop-in TypeScript SDK methods and React components for login, gift links, claim, permissions, and receipts.

+ reference app, docs, tests & runbooks

Outputs compound across the Stellar ecosystem.

Stellar ecosystem impact

Reference infrastructure, not one isolated app

Seedless onboarding

Mainstream users join Stellar with a device passkey instead of seed phrases, reserves, and trustlines.

→ Passkey account on testnet in under 60 seconds.

Consumer-grade transfers

Gift and claim links let anyone receive Stellar assets — even before they have a wallet.

→ Send, claim, and refund backed by onchain escrow.

Safe agent automation

Agents act through scoped sessions with caps and expiry, never the user's private keys.

→ DCA bot capped at 100 USDC/day, revocable anytime.

Outcome-based UX

Apps describe intents — send, swap, bridge in, gift, DCA — instead of hand-building transactions.

→ One intent schema, many Stellar flows.

Developer velocity

Teams stop rebuilding accounts, sponsorship, sessions, and receipts from scratch.

→ At least two reference integrations import the SDK.

Reviewable operations

Sponsor budgets, rate limits, simulation gates, and runbooks keep embedded infrastructure auditable.

→ Public threat model, tests, and dashboards.

System architecture

Authorization stays onchain. The relay only pays and submits.

The user or a scoped session authorizes first. The sponsor relay pays fees and submits only the prepared action.
