About Yoss.gg
Play nowYoss.gg is a peer-to-peer USDC coin flip game on Base, an Ethereum Layer 2 network. Two players wager equal amounts of USDC. A coin is flipped. The winner takes both sides. There is no house edge, no rake, and no fees — every dollar wagered goes to the winner.
How a Coin Flip Works
Pick a side and set a wager
Choose heads or tails and select a wager from $1 to $100 USDC. Your choice is committed cryptographically before your opponent sees it.
Get matched with an opponent
Find a random opponent instantly through matchmaking, or send a private challenge link to a friend. Both players lock equal USDC into on-chain escrow.
Reveal and settle
Both cryptographic commitments are revealed on-chain. The smart contract determines the winner and pays out the entire pot instantly. No delays, no intermediaries.
Provably Fair — Why You Can Trust It
Zero rake, zero fees
Yoss.gg takes nothing from any game. Winner gets 100% of the pot. Compare this to typical crypto gambling sites that take 1–10% of every bet.
Non-custodial escrow
Funds are held by a smart contract on Base, not by Yoss.gg. We never have access to your money. You can withdraw your USDC at any time.
Commit-reveal fairness
Both players commit their choice before either reveals. This cryptographic scheme makes it mathematically impossible for either side to cheat — the same mechanism used in on-chain governance and auction systems.
Fully transparent and verifiable
All game logic runs on Base. The smart contract is public. Every outcome is verifiable on-chain. Anyone can audit the results.
No wallet or ETH required
Sign in with email. Smart accounts handle gas fees behind the scenes. No browser extensions, no ETH, no seed phrases.
