A gold-backed omnichain protocol suite taken from economic architecture to multi-chain testnet and investor demo.
Global Gold demonstrates the new Coincraft model: the same architect who designed the economic machine carried it through spec, contracts, adversarial review, deployment, frontend, and audit handoff preparation.
This was not a tokenomics handoff.
It was full-cycle protocol ownership.
Design → Spec → Build → Review → Testnet → Demo → Audit handoff
Contracts, routes, dashboard, and invariant output are reviewable in the private build dossier.
Global Gold is a gold-backed omnichain exchange protocol: a reserve-backed asset layer, a liquidity and governance layer, cross-chain transport, and an investor-facing demo surface.
The protocol brings together:
It was built as a reviewable system.
Global Gold was not designed as a single vault, a single token, or a single DEX. It was designed as a gold-native trade architecture: gGOLD as the routing asset at the center of every pool, GOLDN as the liquidity steering layer, LayerZero V2 rails as the omnichain transport, and vault-backed gold as the monetary foundation.
Each plate below is an animated drawing. Click one to open it in motion.
Every pool pairs against gGOLD. Instead of fragmenting liquidity across endless isolated pairs, assets route through the gold core — connecting a new asset to the entire system takes one pool, not a lattice. N assets need N pools, not N² pairs.
The center is the highway.
Plate 03 — The Trading Wheel. gGOLD at the center; the jurisdictional gold shell and the L1 membrane around it; every pair routes through the core. Shell 1 shown at designed capacity: twelve slots, with USG live and PAXG and XAUT anchored at launch.
veGOLDN steers the system. Locking GOLDN earns time-weighted voting power; allocating that power to pools directs where emissions and protocol-fee flows go. Governance becomes protocol machinery: it steers the depth.
Delegation also earns fee tiers. The designed fee table runs from 0.30% for undelegated traders down to 0.01% at the deepest tier — and 0.001% on gold-pair hub pools. A 30× discount for the most aligned participants, delivered through a Uniswap v4 dynamic-fee hook.
And participation is rewarded by design: delegators share protocol fees in gGOLD, liquidity providers earn trading fees plus GOLDN emissions, and gold-pair pools are designed for minimal divergence risk because both legs track the same metal.
The system rewards participation through fee share, emissions, and fee tiers.
Plate 06 — The Steering Wheel. veGOLDN vote allocation steers emissions, fee routing, and swap-fee tiers across the gauge ring. Spoke width is vote weight.
gGOLD is omnichain over LayerZero V2 with a lockbox home on Ethereum: bridged supply stays locked at home, so global supply is always anchored where the gold is. Governance state crosses chains as verified messages, not wrapped tokens.
Plate 02 — The Omnichain Elevator Tower. One vertical OFT shaft threads every gGOLD core, anchored to the Ethereum lockbox. The pattern is designed to run on any EVM chain with Uniswap v4; the testnet proof runs on four.
Delegation reports travel in numbered caravans with per-user idempotency cursors. Out-of-order delivery is absorbed, replays are skipped, and recovery is timelocked. The result is monotonic, idempotent omnichain bookkeeping: reviewable and invariant-tested.
Plate 07 — The Caravans. Numbered dispatch from every reporter chain; the hub applies a slice only if it is newer than the per-user cursor, skips replays without reverting, and recovers forward-only behind a timelock.
gGOLD is backed by a communal basket vault: multiple tokenized-gold reserves in one redemption claim, ounce-for-ounce, oracle-free, with a governed path to admit up to twelve gold assets. The architecture is designed so gold from many jurisdictions can back one routing asset — gold does not need to live in one vault to become one monetary layer.
Plate 04 — The Vault Rings. Design vision: twelve jurisdictional gold tokens backed by a ring of independent physical vault operators, no single point of trust. Shipped today: the communal basket vault with a governed path to twelve legs.
gBAR extends the same gold into institutional denominations: KYC-gated ERC-721 bars wrapping fixed blocks of gGOLD, transferable peer-to-peer within the compliance perimeter, always unwrappable back to gGOLD. gGOLD stays permissionless; KYC lives at the gBAR edge only.
Plate 05 — gBAR. Fixed blocks of gGOLD lifted out of plane as compliance-gated bearer bars — implemented as ERC-721 today; the jurisdictional bar ring and marketplace are the roadmap.
The result is a nested system: gold backs the routing asset, the routing asset unifies liquidity, governance steers depth, and omnichain rails carry the structure across networks — an architecture that positions gold as the settlement layer of decentralized trade.
The plates show the architecture as designed — the designed layers all implementable with today’s technology. The four-chain testnet is the proof of the pattern; four chains is simply how many testnets run Uniswap v4 today, not a limit of the design. Where a layer is vision rather than code — the distributed vault-operator ring, the bar marketplace — the plate says so on its face.
The gGOLD vault architecture defines the reserve-backed asset system: minting, redemption, reserve accounting, and solvency constraints.
GOLDN provides the governance and liquidity-steering layer: vote-escrow, gauges, delegation, tiers, and protocol participation mechanics.
Uniswap v4 infrastructure supports the exchange layer, including dynamic-fee hook logic and tier-aware fee behavior.
LayerZero V2 rails connect the system across Base, Ethereum, Optimism, and Arbitrum Sepolia testnets.
The dashboard gives stakeholders a way to inspect the protocol: reserves, solvency, bridge state, trading flows, governance flows, and portfolio state.
The build is packaged with specifications, findings ledgers, invariant output, deployment manifests, runbooks, and auditor-facing documentation.
The Global Gold testnet environment spans four networks: Base Sepolia, Ethereum Sepolia, Optimism Sepolia, and Arbitrum Sepolia.
The omnichain mesh includes twelve LayerZero V2 OFT peer routes.
gGOLD OFT mesh, any-to-any. Hub authority, delegation reporting, and tier passports route through Base.
Cross-chain protocols require more than contracts deployed on different networks: routes, peers, registries, deployment manifests, chain-specific runbooks, operating ceremonies, and verification.
The protocol has to be inspectable across the mesh, not just plausible on a diagram.
Reviewers need more than contracts. They need a surface where the system can be inspected.
The Global Gold dashboard gives reviewers a way to see the protocol in motion: reserves, solvency, minting, trading, bridging, governance, and portfolio flows.
The demo is the window into the protocol. Access is provisioned with the technical walkthrough invitation.
Global Gold originally included a CDP-style debt model.
The basket vault was cleaner, debt-free, easier to reason about, and easier to prepare for audit.
The shipped system changed under review because the basket vault proved cleaner than the debt model.
Knowing what not to ship is the part no dev shop sells you.
Global Gold’s build process was structured around reviewable artifacts:
The rigor exists so a security team has something to inspect.
gGOLD vault solvency invariant suite — archived Foundry run, July 7, 2026. 256 runs · 16,384 calls each · 0 reverts.
The Global Gold build maintained findings ledgers across adversarial review rounds. Issues were recorded, reviewed, remediated, or explicitly carried forward.
The trail matters: finding, decision, remediation, verification, disposition.

Build record — artifact classes maintained across the Global Gold engagement.
Global Gold was built for internal CTO and security review followed by independent third-party audit.
The handoff package is designed to give reviewers the system context they need:
Coincraft prepares the system so a security firm has something coherent to review.
Global Gold proves the new Coincraft model can carry a serious protocol through:
But the deeper proof is architectural judgment.
The system that shipped is the system that survived design pressure.
Those claims come after the audit and the mainnet deployment — not before.
Serious prospects can request a private technical walkthrough of the Global Gold build.
The walkthrough can include:
The walkthrough is a guided inspection of approved artifacts, not repository access or marketing theater.
