Cash Arena rules, risks, and availability.
Cash Arena is the optional real-value contest mode for COIL Extraction Royale on Betacoil. It is in a limited rollout and is not yet available to every account. The rollout is expected to reach 100% of otherwise eligible accounts in supported locations by 1 September 2026. Age, identity, security, risk, and live service checks still apply. Players may lose the full buy-in and disclosed service fee.
An account is not a promise of Cash access.
Cash access is expanding in stages. The rollout is expected to reach 100% of otherwise eligible accounts in supported locations by 1 September 2026. A location-by-location allowlist and a clear live eligibility result still determine whether a paid queue can be entered.
The amount and maximum loss come before confirmation.
No exact stake or fee shown on this public page is an offer. When Cash Arena is available to your account, the live confirmation screen is authoritative for that queue.
1. Review
Before confirmation, the screen must show the buy-in, service fee, total amount to be locked, maximum possible loss, and prize rule.
2. Reserve
Joining the queue reserves the displayed buy-in plus fee in the internal ledger. Reserved funds are no longer available for another action.
3. Escrow
When the room starts, the buy-in moves to match escrow and any displayed service fee is recorded separately.
4. Settle or void
A completed match uses the disclosed payout rule. An eligible, authorized platform void before meaningful gameplay returns the full locked amount, including the displayed fee.
The prize pool follows secured match value—not placement alone.
The service fee is excluded from the prize pool. The prize pool equals the number of participants multiplied by the buy-in.
Extracted value + final settlement value
Each player's non-negative secured arena value becomes their payout weight. A player's share is the prize pool multiplied by their weight and divided by the total weight. Cent rounding is resolved deterministically.
A disclosed deterministic fallback
If every player has zero secured value, the recorded winner receives the pool. If there is no recorded winner, each player receives their buy-in back.
Arena value is a gameplay score and payout weight. It is not Wallet CU and does not carry a fixed dollar value. A high score does not guarantee profit because the result depends on all participants' secured value and the disclosed fees.
Blockchain transfers are real and can be irreversible.
Where Cash access is available, Wallet CU is a display unit for Base USDC: 100 Wallet CU represents approximately 1 USDC. This is separate from arena value collected during play.
Base USDC only
Sending another token, using another network, or sending to the wrong address may cause permanent loss. Recovery is not guaranteed. A deposit is credited only after required confirmations and checks.
Eligibility and review apply
Withdrawal requests may be held for security, sanctions, identity, fraud, or match-integrity review. The current status and any required action must remain visible in the wallet history.
Base transactions are public
Betacoil cannot erase public-chain records. Wallet addresses, transaction hashes, amounts, and timestamps may be visible on the public blockchain and can remain available indefinitely.
Not every failed room has the same outcome.
An eligible, authorized platform void before meaningful gameplay returns the full locked amount, including the displayed fee. After that threshold, the stored match report, replay evidence, settlement state, and incident context require review; a refund is not automatic.
Settlement can pause for review
A replay mismatch, integrity case, or risk review may hold settlement instead of silently finalizing an uncertain result. A hold is not itself a finding against a player.
Keep the match or transaction reference
Use Support with the match ID, room ID, transaction hash, time, and a short description. Possible outcomes include settlement as recorded, an eligible void/refund, or further investigation.
