The judging phase for our building competition is coming to a close with 154 registered builders, 31 final submissions and 2971 tracked transactions.

Among our submissions, we’ve seen projects including launchpads, token bridges, autopayment protocols, NFT rentals, on-chain investment plans and many more use cases besides.As our judges are carefully deliberating who to award as the final winners, first it's time to announce our finalists!

React.Fun - Multi-Chain Token Launchpad Powered by Reactive Contracts (RCs)

Enables creators to launch tokens once and have them instantly tradeable across multiple chains (Ethereum, Polygon, BSC, Arbitrum, Base) with unified pricing maintained autonomously by the Reactive Network.

GoBridge - Fully decentralized, Relay-Free Cross-Chain Bridge

Cross-chain bridging layer for the GoBridge / goUSD ecosystem. Moves value between EVM chains via event-driven callbacks, oracle-guarded swaps, and role-gated execution.

NFT SUB - Where Subscriptions Live On-Chain

TypeScript SDK for Web3 subscriptions using ERC-1155 NFTs. Handles merchant registration, subscription management, and automated renewals via Reactive Network.

Reactivate - RSC Autopayment

An automation layer designed to keep Reactive and callback contracts alive and functional without manual intervention. Developers often face downtime when their contracts run out of REACT or native tokens, especially in high-volume scenarios. Reactivate solves this by combining automated monitoring with intelligent refilling and reactivation.

FluxVault - Yield Optimizer 

Cross-chain yield optimization protocol that automatically maximizes returns across multiple blockchain networks using Reactive Contracts.

LeaseChain - NFT Rentals

Reactive Contract-powered protocol that enables time-bound NFT rentals with automatic expiry and return. Owners lease NFTs for a defined duration, renters enjoy temporary usage rights, and once the rental expires, Reactive Contracts automatically reclaim the NFT to the original owner, no disputes, no intermediaries.

If you're on this list then it means you're in the running for a potential prize but you haven't won yet, so keep an eye on our socials where we'll be announcing the final winners very soon.Big thanks to everyone else who participated, unfortunately not every project met our qualifying criteria but we appreciate every builder who took part and we hope you’ll join us again in our future building competitions and hackathons!

About Reactive Network

Reactive is an EVM-compatible execution layer for dApps built with Reactive contracts. These contracts differ from traditional smart contracts by using inversion-of-control for the transaction lifecycle, triggered by data flows across blockchains rather than by direct user input.

Reactive contracts listen for event logs from multiple chains and execute Solidity logic in response. They can determine autonomously when to transmit data to destination chains, enabling conditional cross-chain state changes. The network delivers fast and cost-effective computation via a proprietary parallelized EVM implementation.
