VerifyVASP Alliance


VerifyVASP was developed by Lambda256, an affiliate of Dunamu, the operator of Korea’s largest cryptocurrency exchange Upbit. The protocol shot to prominence in March 2022 as South Korean VASPs sought to meet their travel rule obligations by 25 March 2022.

At the time, international VASPs who wished to continue to transact with Upbit had little choice but to implement VerifyVASP. During this period, a simplier version of the protocol - VerifyNAME - was introduced for international VASPs.

Originally, the four major cryptocurrency exchanges in South Korea - Upbit, Bithumb, Coinone and Korbit - decided to launch a joint venture to co-develop solutions for travel rule, however Dunamu opted out citing the move as being perceived as collusion by the major players.
