Amazing projects on dfuse


Exclusive token-based chat rooms

Building on the concept of providing proof-of-attendance tokens to developers and attendees of conferences/hackathons, the team behind Etheroom wanted to create chat rooms that can be accessed only by accounts that contain specific tokens. From there, they realized that they could give users the ability to mint their own tokens, thus allowing them to create more granular chat rooms, adding greater flexibility to their platform. They utilized dfuse to stream all event logs from the token contract so as to build a whitelist of accounts that can access specific chat rooms. From there, they were able to listen for any deltas, in order to revoke access should a user send that token to another address.



On-chain messaging delivered through MetaMask

1 of the 5 ETHWaterloo finalists

The Connexion team set out to tie ENS and MetaMask together to create a simple messaging platform that works over the Ethereum blockchain. Hashes of the message are pushed on chain to the Connexion Smart Contract, while the message contents are uploaded to IPFS.



Listen to the Ethereum memory pool

Winner of the dfuse Grand Prize

The team behind EthRhythm wanted to provide a real-time visual and audio representation of the ever-changing mempool of the Ethereum mainnet. They looked to dfuse to provide a real-time stream data, and utilized our GraphQL subscription to stream pending transactions.
