APRIL
On April 24, Luck.io, a decentralized casino running on the Solana blockchain via Proov Protocol, announced it is shutting down.
Luck.io billed itself as the largest and fastest-growing on-chain casino, offering games like Roulette, Plinko, and slot titles it described as "provably fair," a term in crypto gambling referring to outcomes generated by cryptographic random number functions that are verifiable on-chain.

The platform was built on Proov Protocol, the underlying blockchain infrastructure that powered its bets and settlements. It provides verifiable randomness for game outcomes and non-custodial smart contracts, so players retain control of their funds at all times, and full transparency with every bet recorded and auditable on the Solana (SOL) blockchain.
Luck.io described itself as "trustless" and "non-custodial," with on-chain settlements verified by SolScan. Players could also benefit from daily lootbox rewards and a transparent bankroll system.
Because it operates on public, immutable blockchain data rather than a centralised server, Luck.io was not licensed in the traditional sense, though certain jurisdictions were blocked in line with local regulations.

Why is it shutting down?
The platform did not give a specific reason for its closure.
In a post on X, Luck.io wrote,
"What started as a concept soon became the largest and fastest growing on-chain casino. The concept works. We hope the tech powering Luckio will find a new home in the near future. Thank you for playing on Luckio!"
The announcement did not acknowledge the scrutiny the platform had faced over its fairness claims.
Among the critics was Foobar, a pseudonymous crypto developer and former machine learning scientist at Google, who once publicly questioned the validity of Luck.io's random number generation.
TheStreet Roundtable reached out to Luck.io for a comment and had not received a response by the time of publication.

What should players do now?
Luck.io has urged all players to withdraw their funds from their Smart Vaults immediately, either directly through the Luck.io website or via the Vault Withdrawal Tool provided by Proov Protocol.
For users affected by geo-restrictions who cannot access the site, Proov Network offers a browser-based tool to query and withdraw balances directly from the smart contract.
A self-hosted version of the tool is also available for users who prefer it. P
layers without the technical knowledge to call directly from the contract are encouraged to use Proov's guided withdrawal interface to recover their funds safely before the platform goes dark.
