01The Problem

Legacy finance is structurally broken.

Legacy infrastructure can't keep up. Stablecoins are inevitable.

  1. / 01

    2–5days

    Cross-Border Delay

    SWIFT settlement takes 2–5 days. Multiple intermediaries. Fees up to 6%.

  2. / 02

    Siloed

    Liquidity Fragmentation

    Bank-issued tokens create isolated pools. No interoperability = no real digital money.

  3. / 03

    1st

    Institutional Gap

    No Japan platform combined HSM custody + ZK privacy + full API. Until now.

Legacy rails vs. NexBridge

Settlement time and cost: legacy correspondent banking vs. on-chain settlement. Bar lengths are illustrative.

NexBridge ~30 sec · T+0

03Enterprise Security

Japan’s only HSM-First custody

Private keys = ownership. Three layers, integrated.

  1. HSM

    Hardware Security Module

    Keys never leave tamper-resistant hardware. FIPS 140-3 Level 3 certified — with NexBridge custom FM running inside the secure boundary.

    Powered by Thales Luna HSM · Technology Partner

  2. MultiSig

    Multi-Signature

    No single key can authorize transactions. M-of-N threshold across institutional signers.

  3. Policy Engine

    Programmable Approval Workflows

    Encode compliance, velocity limits and approval logic at the protocol layer.
