Build Complete Club Ecosystems
Connect consumer experiences to on-chain contracts. Staking, rewards, commerce, IoT—one unified platform with forward deployed engineers to help you ship.
// Initialize club with staking + rewards
const club = await fexr.clubs.create({
name: 'Lifestyle Pass',
chain: 'polygon',
staking: { token: 'USDT', minStake: 100 },
rewards: {
yieldSource: 'partnership',
redeemables: ['gym_access', 'products']
}
});
// Contract deploys automatically
console.log(club.contractAddress);Consumer + On-Chain, Unified
Build apps that connect real-world commerce to blockchain contracts. Fexr streamlines the integration so you can focus on your product.
Staking Contracts
Deploy club contracts where members stake USDT, USDC, or custom tokens. Define distribution sources, lock periods, and payout rules through config.
Reward Systems
Issue tokens, badges, redeemables, or brand perks. Tie rewards to activity, purchases, or staking levels. Everything on-chain and auditable.
Commerce Integration
Connect Shopify, Stripe, POS systems. When members purchase, a portion flows to club treasury automatically. Compliant revenue sharing.
IoT & Sensor Data
Ingest telemetry from fitness equipment, facility sensors, or wearables. Activity data triggers contract logic and reward distributions.
Compliance Built In
Fexr helps navigate regulatory complexity. Staking structures, reward programs, and data handling are guided by compliant frameworks.
Multi-Chain Deployment
Deploy contracts to Polygon, Solana, or Avalanche. Same SDK, same logic—different chains. Bridge assets between clubs seamlessly.
Agent automation
Wire AI agents as authorized club participants. Agents execute governance votes, route distributions, and manage liquidity — all within the rules the club defines on-chain.

Developer Resources
Developer FAQ
Common questions from teams building on Fexr.
01.What does the FDE engagement look like?
Our forward deployed engineers join your Slack, review your architecture, build custom connectors, and stay on-call through launch. Think of them as an extension of your team.
02.Can I deploy my own contracts?
Yes. Bring your own contracts and connect them to Fexr. The platform orchestrates the flow — staking, reward distribution, oracle verification — while you own the contracts and control the business logic.
03.How do you handle compliance?
Fexr guides staking and reward flows within compliant frameworks. Our team reviews your use case and helps ensure your contract design meets regulatory requirements for your jurisdiction.
04.Which chains are supported?
Polygon, Solana, and Avalanche today. Same SDK, same APIs—different chains. Multi-chain clubs and asset bridging are available on enterprise plans.
