Four principles that define ZiGX.

Purpose-built for institutional settlement, not speculation. Every design decision is deliberately conservative, and every claim is grounded in single-asset backing.

i.100% USDC-backed.Every ZiGX is designed to be backed 1:1 by USDC held in institutional custody. Over-collateralisation policy target of 102–105%. No fractional reserve. No algorithmic backing. No mixed reserves.Reserve
ii.USD parity, via USDC.Stable value referenced to the US Dollar through USDC — a regulated, attested reserve asset issued by Circle. A settlement instrument, not a speculative asset.Parity
iii.Institutional custody.USDC reserves designed to be held with FCA-regulated institutional custodians, fully segregated from operating funds. ZimX is onboarding with Zodia Custody and Archax as intended custody partners for the corridor.Custody
iv.Multi-signature governance.Reserve operations require multi-signature approval across three roles — Governance multisig, Timelock controller, and Guardian. No single person can move reserves unilaterally. All critical parameter changes require timelock delay.Governance

Questions, answered plainly.

ZiGX is a USDC-backed digital settlement asset designed for use within the ZimX ecosystem. It enables faster, cheaper settlement across the UK–Zimbabwe corridor with an over-collateralisation target of 102–105%.
ZiGX is designed to be backed 1:1 by USDC, the US dollar stablecoin issued by Circle. Every ZiGX in circulation represents an equivalent unit of USDC held in institutional custody. Reserve composition is single-asset by design — no mixed reserves, no fractional backing, no algorithmic component.
USDC is issued by Circle, a US-regulated financial services firm, and is backed by cash and short-dated US Treasuries held with regulated custodians. It publishes monthly third-party attestations of its reserves. Using USDC as the sole reserve asset gives ZiGX transparent, audited, regulated backing.
No. USDC is the reserve asset. ZiGX is the corridor-specific settlement instrument minted against verified USDC reserves within the ZimX ecosystem.
No. USDC is used as a reserve asset. There is no commercial partnership, endorsement, or affiliation with Circle at this stage.
ZiGX is a cross-border settlement instrument built for the UK–Zimbabwe corridor. It operates alongside, not in place of, domestic monetary infrastructure.
Base — an Ethereum Layer-2 network. Base inherits Ethereum's security model, offers fraction-of-a-cent transaction costs, ~2 second block times, and full institutional tooling compatibility.
ZiGX is designed as a settlement instrument, not an investment product. It is non-yielding and not intended to generate return for holders.
ZiGX is permissioned and gated by ZimX ecosystem onboarding and compliance verification. It is not intended for open retail speculation.
