Aster

Multi-chain · off-chain matching

Facts

Chain: Multi-chain
Order Book Type: off-chain matching
Withdrawal control: Aster-run 4-node validator bridge (3/4 to credit a deposit, 2/3 to release a withdrawal); no permissionless forced-exit documented. Multi-chain (BNB / Ethereum / Arbitrum / Solana), USDT-settled, which carries bridge-dependency risk.
Operator surface: Aster-operated matching engine; privileged roles can pause trading, adjust fees/limits, change price sources, and force liquidations. Backed by the Aster Liquidity Pool (ALP); a dedicated insurance fund is NOT documented.
Upgrade authority: Upgradeable vault proxy; a 2024-09-13 audit found a single address could initially drain the vault; since committed to a multisig (analysis notes it is still a few EOAs). No upgrade/admin timelock documented. USDF collateral sits in Ceffu → Binance custody (single-CEX concentration).
Multisig: See venue docs
Last SolGov check: n/a
