Proof of reserves

Reserves on GM Markets are independently attested by a third-party proof-of-reserves service provider. The attester reads share balances directly from segregated customer accounts at regulated US broker-dealers such as Alpaca Markets and Interactive Brokers and publishes the attested values on-chain in real time.

#What the attestation contains

For every asset, the on-chain attestation publishes:

• Live token supply — total outstanding tokens for the asset across all chains
• Attested broker balance — number of underlying shares held in segregated custody
• Backing ratio — should be ≥1.0 at all times
• Attestation timestamp — when the reading was taken
• Attester signature — cryptographic proof that the data came from the third-party attester

Every token outstanding is backed 1:1 by a corresponding share at the broker partner, and you can verify this independently at any time.

#How to verify

The Proof of Reserves page shows the live token supply, attested broker balance, backing ratio, and a link to the on-chain attestation contract for every asset. From there you can pull the raw on-chain data directly via any block explorer or RPC client.

#Why this matters

Proof of reserves is the mechanism that turns "we say it is backed" into "you can prove it is backed." It is the structural reason a tokenized asset on GM Markets is meaningfully different from a balance entry on a centralized exchange.
