Mine the metal.

Iridium turns on-chain randomness into a fast, transparent game. Each round runs a few minutes. You deploy ETH onto a board of 24 cells, Chainlink VRF decides the single winning cell, and the round’s entire pot — every losing deploy plus a batch of freshly-mined IRIDIUM — is paid out to whoever backed it. The ETH simply changes hands between miners, with a small protocol fee that funds buyback-burns and the jackpot. There’s no keeper: anyone can close a due round permissionlessly and earns a small reward for doing it.

Twenty percent of every round’s mined IRIDIUM is set aside into The Spike, a jackpot that builds round after round. On a random winning round the whole Spike cracks open and dumps onto that round’s winners on top of their normal share — and that payout lands with an ETH bonus on top, funded by the 3% Spike-prize fee leg. The longer it goes unhit, the heavier it gets.

IRIDIUM is mined into existence, capped at 7,000,000 — forever. The game contract is the only address that can ever mint IRIDIUM, and it mints strictly against a cumulative counter that can never exceed 7M. There is no team allocation, no presale, no second minter. Each active round mines a tapering slice — starting around 7 IRIDIUM and shrinking as the remaining headroom is drawn down — out to that round’s players. The cap isn’t a number we promise to stop at; it’s enforced in the token itself, and the mint counter only moves one way.

That’s what makes the deflation real. Most “capped” mining tokens — ORE, GODL and friends — are re-mintable: their cap is a refillable bucket. Burn a token and you don’t shrink the supply, you just open “headroom” under the cap that the protocol mints straight back into. The burn is cosmetic; the float flatlines or creeps up. Iridium counts the cap against cumulative mined, not current supply — so a burned IRIDIUM is gone and can never be re-created; every burn permanently lowers the effective ceiling. Pair that with a buyback that burns 100% of what it buys and the circulating float peaks below 7M and then only ever falls. A one-way ratchet, down.

The 3% buyback fee accumulates as ETH. A permissionless call swaps it for IRIDIUM on the open market and burns 100% of what it buys — the bought-back IRIDIUM is destroyed forever, never resold or recycled. (Stakers are paid separately, from the 2% ETH fee leg, so none of the buyback is diverted.) Steady buy pressure plus a permanently shrinking float make IRIDIUM structurally more scarce the more the game is played — every burn is forever, so circulating supply peaks below the cap and then only declines. The cap counts cumulative mined, so supply can only ever move down.

Stake IRIDIUM to earn real ETH — the 2% staker fee leg from every deploy streams into the pool and accrues to stakers pro-rata by stake. Rewards are ETH, not IRIDIUM, so staking never dilutes supply. There are no lockups on your principal — unstake any time and it comes straight back, and your accrued rewards are yours to claim whenever you like. Rewards accrue continuously from the moment you stake; if nobody is staked when a fee leg arrives it waits in the reserve and is credited to the next stakers, so no reward is ever lost.

Every winning cell is drawn from Chainlink VRF v2.5 — a verifiable random function. Crucially, the randomness is only requested after deposits close, so the winning cell cannot be known by anyone while the round is open. Chainlink’s coordinator verifies its cryptographic proof on-chain before the callback can set the winner; neither the team nor Chainlink can predict or alter it.

You don’t have to take our word for it — recompute any round’s winner yourself from chain data on the Provably Fair page.

Iridium is built to be trusted without trusting us. Three guarantees back that up — one already enforced on-chain today, two that harden the code toward being permanently un-changeable.

Currently live on Base Sepolia testnet for open testing. Before a Base mainnet launch the contracts get an external audit and the owner key moves to a multisig; every contract address is public and verifiable on the explorer.

No presale. No venture capital. No insider or team allocation. The only way IRIDIUM comes into existence is mining rewards earned by players, minted by the game contract up to the cap — transparent and on-chain. Everyone starts on the same grid.
