2/ @tokifinance & @datachain_en are long-time IBC contributors.
Their team led work to bring the first bank-backed RWAs for Japan onto IBC, as well as other contributions.
Now they’re building new implementation to use IBC on OP Stack.
Japan's largest financial institutions, including MUFG, SMBC, Mizuho & JPX, are behind @progmat_en, an issuance & management platform for bank-backed RWAs.
@tokifinance @datachain_en build its on-chain infrastructure, including IBC-based interoperability.
