GemStep makes movement reward-friendly

A blockchain-based reward solution that connects devices, turning verifiable activity into predictable rewards under transparent governance.

View docs Launch app
Verified step logging
EIP-712 signatures bind user, beneficiary, source, chainId, and deadlines—easy to audit and harder to forge.
Caps & halving
Daily caps and epoch halving keep issuance predictable and transparent as adoption grows.
Source-specific controls
Each provider can require proof or attestation, with distinct limits and policies.
Cross-chain ready
Governance patterns can control execution for upgrades and parameter changes.

What’s included with GemStep

Our security-first architecture embeds critical logic on-chain. This enforces conservative defaults, establishes strong guardrails, and drastically minimizes the off-chain attack surface.

Deterministic on-chain core
Rewards, caps, and validations live on-chain so behavior is inspectable and consistent.
Security-first controls
Role-based admin, pause/emergency patterns, and upgrade gates via governance/timelocks.
Operational support surfaces
Docs, clear error states, and versioned policy flags for sources and attestations.
Privacy-aware design
Pull only the minimum movement data needed and tie it to a wallet you control.

How it works

Connect your source, verify deltas under protocol rules, then claim rewards on-chain.

01
CONNECT
Authorize Data Access
Connect providers via OAuth. Read-only access—no changes to your health account.
02
VERIFY
Generate Attestation
Pull latest steps, compute deltas, apply caps/stake rules, and prepare a typed-data bundle.
03
EARN
Execute Claim
Sign with your wallet and submit. The contract mints rewards to your address—non-custodial.

For builders & auditors

Transparent architecture, minimal off-chain assumptions, and versioned policy flags for sources.

Modular + upgradeable
Split responsibilities across step logging, staking, caps, emergency controls, and governance surfaces.
Thin backend, clear proofs
Keep off-chain services stateless where possible; tie actions to EIP-712 signatures and policy checks.
