numa. (stylized with a period) is a non-custodial DeFi protocol on Arbitrum and Sonic that issues LST-backed synthetic assets (nuUSD, nuBTC, nuETH, nuGOLD) through a burn-and-mint tokenomics model. The protocol suffered two separate exploits in 2025 — a $506K price manipulation attack in April and a $313K collateral valuation exploit in August — resulting in cumulative losses exceeding $800K and a token price decline of approximately 99% from its peak. ZachXBT has flagged the entity in the context of trust intelligence monitoring.
