Probly, an on-chain prediction market application, has gone live on TxFlow L1 through the network's TxFlow Improvement Protocol 3 (TIP3). The deployment gives users access to more than 5,000 events and 12,000 markets at launch, covering everything from World Cup sports to geopolitics and crypto prices.
What TIP3 unlocks
TIP3 is the mechanism that allowed Probly to build directly on TxFlow L1. The protocol handles the technical plumbing — smart contract deployment, event resolution, and settlement — so the app can focus on the user experience. For TxFlow, it's the first major prediction-market use case to land on the layer-1 chain.
Scale of the launch
Probly isn't starting small. The team says it supports more than 5,000 events and 12,000 individual markets right out of the gate. That's a lot of bets to track. The platform is designed around real-time events and changing expectations, meaning odds shift as news breaks.
The six categories
Markets are grouped into six buckets: World Cup Sports, Geopolitics, Crypto, Finance, Economy, and Politics. That covers a wide range — from who wins a soccer match to whether a central bank hikes rates. Crypto traders will find markets on token prices and network upgrades, while the geopolitics section tracks conflicts and elections.
Prediction markets have been a staple on Ethereum and Solana for years. TxFlow now has its own native option. The timing isn't accidental — with the World Cup approaching, sports markets could drive early volume. Whether Probly can attract liquidity away from established players remains to be seen, but the infrastructure is in place.
Users can start trading immediately. The platform is live, and the first events are already resolving.
