Frequently Asked Questions

Q: What causes sudden liquidation waves across perpetual futures markets?A: Liquidation waves emerge when mark prices diverge from index prices by more than 2.8%, triggering cascading margin calls due to insufficient isolated margin buffers across aggregated open interest positions.

Q: How do decentralized exchanges detect front-running attempts?A: DEXs monitor transaction inclusion timestamps against mempool broadcast times, flagging any swap execution occurring within 12 seconds of a pending arbitrage bot transaction with identical input/output token pairings.

Q: Why do some stablecoin redemptions fail despite sufficient reserves?A: Redemption failures occur when the underlying collateral vault smart contract enforces time-locked settlement windows, rejecting redemption requests submitted outside designated 15-minute intervals aligned with off-chain custodian reconciliation cycles.

Q: What determines whether a new token listing qualifies for margin trading eligibility?A: Eligibility depends on sustained 30-day average order book spread below 0.32%, minimum 12,000 unique wallet addresses holding non-zero balances, and absence of any on-chain blacklist flags from Ethereum Name Service resolution logs.
