SigmaUSD
Profil du Stablecoin
SigmaUSD (SIGUSD) est un stablecoin algorithmique — son ancrage à USD est maintenu par la mécanique du protocole on-chain plutôt que par des réserves off-chain. Actuellement, 212 k $US sont en circulation sur 1 réseaux blockchain. Le mécanisme ajuste l'offre (mint et burn) en fonction des écarts de prix par rapport au peg cible.
À propos de SigmaUSD (SIGUSD)
SigmaUSD is a UTxO-based stable coin on the Ergo blockchain - an instantiation of the AgeUSD protocol.
Using the SigmaUSD app, users swap ERG for the equivalent value of SigUSD. The SigUSD is backed by collateral ERG provided by Reserve Providers at a reserve ratio of 400% - 800%.
Activité récente de l'offre
SigmaUSD (SIGUSD) supply was unchanged in the last 24 hours, was unchanged over the past week, and contracted by 1 $US over the past 30 days.
Steady issuance: supply has held roughly flat (-0.00% over 30 days), consistent with mature stablecoin liquidity dynamics.
Historique de l'Offre
Network distribution
SigmaUSD circulates across 1 blockchain network. Ergo hosts the largest share at 100.00%. Cross-chain distribution has remained broadly stable over the past 30 days.

| Ergo | 212 k $US | 100.00% | 0.00% | -0.00% |
Historique de stabilité de l'ancrage
SigmaUSD (SIGUSD) relies on protocol-level supply rebalancing rather than direct asset redemption to defend its 1.00 USD peg. The spot price is currently $0.9999 (-0.010% deviation). Algorithmic designs carry materially higher peg-failure risk than reserve-backed stablecoins — the May 2022 Terra/UST collapse remains the canonical reference case.
Comment les stablecoins algorithmic défendent leur ancrage
Algorithmic stablecoins attempt to balance supply and demand through protocol-level mint/burn incentives — typically against a paired governance or seigniorage token. When the price drops below $1.00, the protocol burns supply (often by letting holders swap into a discounted asset); when it rises above $1.00, the protocol mints new tokens. This design only holds when the paired asset retains independent demand. If the market loses faith in the paired asset, the feedback loop reverses and produces a hyperinflationary "death spiral" — the failure mode that wiped out roughly $60B in the Terra/UST collapse.
Implications pratiques pour les détenteurs
- Peg-failure tail risk is materially higher than reserve-backed designs. Position sizing should reflect this — algorithmic stablecoins are not a "cash equivalent" for risk-management purposes.
- Read the latest collateralisation ratio carefully: many "algorithmic" stablecoins have since migrated to partial or full collateralisation. The label can lag the actual mechanism.
- Reflexive feedback loops mean small redemption pressure can cascade. Exit liquidity should be assessed during normal conditions, not after stress begins.
- Mantapex tracks peg deviation in real time from DeFiLlama price feeds, but for high-value holdings cross-check directly on at least one independent venue (CoinGecko, the issuer's own dashboard, or an on-chain DEX).
Peg-stability commentary is based on the mechanism class (algorithmic) and is provided for educational purposes only — it is not financial advice. Past peg stability is not a guarantee of future performance, and even the highest-quality stablecoins have historically traded outside their target band during banking, regulatory, or liquidity stress.
Comparer SigmaUSD à d'autres stablecoins algorithmic
Below are the largest algorithmic stablecoins tracked on Mantapex alongside SigmaUSD (SIGUSD). Comparing supply and chain footprint within the same mechanism class is more meaningful than cross-class comparison, because the underlying peg-defence assumptions are different.

Entre les classes de mécanismes
If you're researching SIGUSD as part of a broader stablecoin allocation, it's worth comparing it across mechanism classes — each design has different counterparty, custody, and tail-risk profiles.
