Reserves you can verify, not just trust.
AuraReserve is a proof of reserve platform for organizations that hold assets - physical or digital - on behalf of others. We turn balance-sheet claims into cryptographic proofs that any client, auditor, or regulator can verify on their own.
Our Mission
Make reserve transparency a primitive, not a privilege.
For most of history, "trust me" has been the dominant settlement layer of finance. Custodians, exchanges, vaults, and issuers told their clients what they held - and the clients had to take their word for it. Audits help, but a quarterly snapshot signed by an accountant is not the same thing as a proof you can verify yourself.
Cryptography changes that. Merkle Sum Trees let an organization commit to a full reserve and then issue per-entry proofs that can be checked in milliseconds, without exposing other clients' data. AuraReserve packages that workflow into a hosted (and self-hostable) platform so any team can publish a proof of reserve without becoming cryptographers.
We started AuraReserve because the same primitives that secure billions in digital assets should be available to gold vaults, gemstone dealers, securities custodians, and stablecoin issuers - anyone whose customers deserve a verifiable answer to "is my asset really there?"
What We Stand For
Four principles that shape every product decision.
Privacy by Default
Every proof reveals the absolute minimum: that one entry is in the reserve, and what the total is. Nothing else.
Independent Verifiability
If a proof can't be verified independently, it's a claim, not a proof. We publish the math and the tooling.
Open Core
The verification primitives are open source. You can self-host, audit the code, or run a verifier offline.
Asset-Agnostic
Gold bars, gemstones, exchange balances, stablecoin reserves - the same Merkle Sum Tree works for anything you can hash.
Who Builds This
A small, independent team based in Vienna, Austria.
a31 Labs
Independent software studio · Vienna, Austria
AuraReserve is developed and operated by a31 Labs, an independent software studio focused on cryptography, distributed systems, and developer tooling. We build the platform end-to-end - from the cryptographic libraries to the dashboard to the on-chain publication path.
