We present FaFROST+, the first two-round Schnorr threshold signature scheme achieving full adaptive security under the Algebraic One-More Discrete Logarithm (AOMDL) assumption with identifiable aborts. Building on the FROST framework, FaFROST+ preserves its communication efficiency while dispensing with the LDVR assumption introduced at CRYPTO'25. Our result demonstrates that round-optimal adaptive security, practical efficiency, and identifiable aborts are simultaneously achievable under the
