Protocol Guide

Everything you need to understand STABLEGOLD in one page.

Plain-language rules for fees, daily state, rebalance logic, and how to participate.

What is STABLEGOLD?

STABLEGOLD (SGLD) is a Solana token that mints and redeems directly against a USDC reserve vault — there is no AMM or liquidity pool. Price is calculated on-chain:

Price = USDC Reserve ÷ Circulating Supply

The protocol targets +0.25% daily growth. Fees collected before that target is met build the reserve; fees after go into a reserve support vault. All trades are direct on-chain calls signed from your own wallet — we never hold your funds.

Fee Structure

Simple fee paths with visible routing.

Every fee has two parts: a fixed 0.1% dev cut and a protocol portion whose destination depends on whether the daily target has been cleared yet.

Action Total Fee Dev Cut Before Midnight EST Target After Midnight EST Target
Buy 3% 0.1% 2.9% deepens USDC backing vault 2.9% minted into reserve support vault
Sell 2% 0.1% 1.9% burned (SGLD destroyed) 1.9% routed to reserve support vault
Transfer 1% 0.1% 0.9% burned 0.9% routed to reserve support vault
Tap to Pay 1% 0.1% 0.9% burned 0.9% routed to reserve support vault

Daily State

Two deterministic modes — reset at midnight EST.

Each day the protocol starts in Phase A. Once cumulative buys push the price to the +0.25% target, it flips to Phase B for the remainder of that day. It cannot flip back. The clock resets at midnight EST.

Price is monotonically non-decreasing within a day — a sell never lowers the implied price. A buy that would cross the target is split automatically: just enough processes at Phase A rates to land exactly on the target, the rest at Phase B rates, all in a single transaction.

Phase A · Before Target

Reserve-building mode

  • Buy: 2.9% deepens the USDC backing vault
  • Sell: 1.9% burned (SGLD destroyed)
  • Transfer: 0.9% burned
  • Tap to Pay: 0.9% burned
  • Every action also takes a 0.1% dev fee

Phase B · After Target

Reserve-support accumulation mode

  • Buy: 2.9% minted into reserve support vault
  • Sell: 1.9% routed to reserve support vault
  • Transfer: 0.9% routed to reserve support vault
  • Tap to Pay: 0.9% routed to reserve support vault
  • Every action also takes a 0.1% dev fee

Rebalance Engine

Adaptive, but bounded.

Market signals (gold price move, DXY, US 2Y yield, geo risk, inflation, news sentiment) are mapped to a stress score from −1.0 to +1.0. That score sets the Gold/USDC target ratio, clamped to 30%–70% rails. Rebalance only fires on material drift from target (7.5% effective drift). Realized upside is tracked separately from the base layer.

  • Trigger: 7.5% effective drift from target ratio
  • Gold/USDC target range: 30% – 70%
  • Signal inputs: gold move, DXY, 2Y yield, geo risk, inflation, sentiment
  • Upside tracked separately — base layer accounting stays clean

Layer Separation

Base utility and treasury upside are not mixed.

  • Base layer: daily fee-supported progression toward the +0.25% target
  • Upside layer: rebalance gains and hedge wins tracked separately
  • Clear accounting keeps protocol behavior easy to audit
  • Community can verify both layers independently on-chain at any time

Community

Usefulness over hype.

  • Focus on wallet flow clarity and merchant adoption
  • Raise blockers and UX issues early and clearly
  • Promote practical education for new users
  • Keep discussion constructive, specific, and evidence-based
