Proof of reserves

Each Twin stablecoin is designed to hold a 1:1 peg to its reference currency (ARGt ↔ ARS, BRAt ↔ BRL, etc.). This page explains the backing model and where the reserve attestation will be published.

The backing model

• 1:1 peg — each token in circulation represents one unit of the local currency, backed by reserves.
• On-chain verifiable supply — each token's circulating supply is public and auditable on every network's explorer (see Contracts). The burn & mint bridge preserves total supply across networks: what is minted on one network is burned on another, so aggregate circulation reflects real issuance.
• Off-chain reserves — backing is held in reserve assets denominated in (or referenced to) the relevant currency.

How it will be proven

Twin's proof of reserves will combine two sources:

1. On-chain circulation — the sum of each token's supply across the 4 networks, read directly from the ERC-20 contracts. It is public and trustless.
2. Reserve attestation — a report of the backing assets, verified by an independent third party, published periodically.

Coverage is expressed as the reserves / circulation ratio, which must stay ≥ 100% per token.

Verify circulation today

Even though the attestation is not published yet, anyone can verify a token's on-chain circulation:

1. Open the token address on each network's explorer (see Stablecoin contracts).
2. Read the ERC-20 totalSupply.
3. Sum the supply across the 4 networks to get the token's aggregate circulation.
