My Project Rooms
Your active engagements, team activity and deadlines.
01 / The workflow
The work starts after the bid.
A hiring marketplace should not disappear once a developer is chosen. Web3Sphere gives both sides a shared operating layer until the project ships.
Sync room
One room for all the work
The client and developer get a private workspace for tickets, decisions, files, meetings, and milestones — all in one place.

02 / Open opportunities

Every brief includes the outcome, team context, milestone structure, and the tools you will use after the award.
