Citi, DTCC, and other major institutions are coalescing around Hyperledger Besu, an open-source, EVM-compatible enterprise blockchain maintained by the Linux Foundation, as their preferred infrastructure for tokenized deposits and collateral settlement. The convergence is notable because DTCC's involvement implies potential integration with existing clearing and settlement infrastructure rather than a parallel system.
For Armada, tokenized T-Bills are an accepted collateral type on the crypto repo desk. If DTCC-connected tokenized collateral migrates onto Besu rails, Armada's operational and Fireblocks custody setup needs to confirm compatibility with that settlement layer. This is an early-stage infrastructure watch item rather than an immediate action, but tracking DTCC's Besu deployment timeline is worthwhile.
