Obsidian

Making RWA private.

ZK-SNARKs integrated into the ERC-1400 standard. The stealth layer for RWA.

Try it with real proofs
A network of cube clusters, solid in the centre and fading to nothing at the edges

A security token tells everyone who owns what.

ERC-1400 gave tokenised securities what they needed to be issued properly: partitions, transfer restrictions, documents, issuer controls. It also put every holder, every balance and every trade on a public ledger, readable by anyone, forever.

No fund publishes its cap table. No desk announces its position before it finishes building it. Obsidian keeps the standard and its rules, and takes the cap table off display.

Any security you can tokenise, you can shield.

Illustrative values. The partition stays public, and so do the moves into and out of the shielded side. Everything in between is what the second view shows.

How a position goes dark and stays compliant.

  1. A flat green slab with pale cubes rising from it

    Shield

    A holder moves tokens into the shielded side of the same ERC-1400 token. The deposit itself is public. What it becomes is a commitment: a number in a Merkle tree that says nothing about who holds it or where it goes next.

  2. A pyramid of cubes, solid green at the peak and breaking apart into white cubes at the base

    Prove

    To transfer, the sender builds a ZK-SNARK on their own machine. It shows they own the notes they spend, that inputs equal outputs, and that every receiver is on the issuer's eligibility list, without naming anyone.

  3. A wide field of pale cubes with a dark green hollow at its centre

    Verify

    The contract checks the proof and nothing else. If it holds, the spent notes are nullified and new commitments are written. No address pair, no amount, no balance change to read.

  4. A stepped tower of cubes rising from a dark green base to a white top

    Control

    The public side is still plain ERC-1400: partitions, documents, forced transfers. On the shielded side the controller can pause the pool and freeze a note once it is disclosed. It cannot move what it cannot see.
