Case Study
Versus-X
Where skill is the wager,
settled on-chain.
Versus-X is a skill-based Web3 sports gaming ecosystem: realistic games like pool and golf where players wager on their own skill and settle trustlessly on-chain. VTS Labs contributed to the game development and engineered the blockchain layer behind it.

01 · THE CHALLENGE
Make skill pay out, and make players trust it
Skill-based wagering only works if players trust the payout. Versus-X needed real sports games that feel like the web2 titles its veteran team is known for, wrapped in web3 economics that settle fairly and transparently, without handing control to a house. The hard part is bridging two worlds: a polished, responsive game loop on one side, and an on-chain system that escrows stakes, resolves outcomes, and pays winners trustlessly on the other.
02 · WHAT WE BUILD
Game development, and the blockchain layer behind it
A complete visual identity grounded in the game's world, plus a multi-page Framer site that carries lore, classes, roadmap, and team, and routes every visitor toward the community.
On-chain skill-based wagering
Smart contracts that take a player's stake, hold it in escrow, resolve the wager against the match result, and release the payout with no middleman.
VSX token integration
Integrated the VSX token (ERC-20 on Polygon) as the wagering and rewards currency across matches and competitions.
Game development & wallet integration
Contributed to the realistic sports builds and connected wallets so a player moves from match to payout in one flow.

HOW WE ENGAGED
PRD-first, fixed scope, no surprises
Every VTS build starts with a product requirements doc that locks the scope and the price before a pixel moves. Stone of Jordan ran the same way: define, design, build, hand off.
HOW WE ENGAGED
We define the build before we build it.
Define
Scope the integration
We mapped how a web2 game loop and an on-chain wagering system fit together before writing a contract.
Build
Engineer and wire it in
We built the contracts and token integration and wired them into the game so the two behave as one product.
Test and harden
Test and harden
We tested the wagering flow against real match conditions so stakes and payouts hold up under real usage.
