What is stGGBR?
stGGBR (Staked GGBR) is the yield-bearing, liquid staked version of the GGBR token. When you deposit your GGBR which represents audited, in-situ gold reserves and supports global climate action through carbon credit generation, into the staking vault, you receive stGGBR in return.
Because stGGBR is built on the widely adopted ERC-4626 tokenized vault standard, it acts as a universal receipt for your staked assets. This means your tokens are never locked up; you retain full liquidity while continuously earning a sustainable yield.
How the Yield Works: Dynamic APR Targeting
Unlike traditional staking mechanisms that distribute new tokens directly to your wallet, stGGBR uses an auto-compounding exchange rate model.
Growing Value, Not Quantity: When you hold stGGBR, your token balance stays the same, but the value of each stGGBR token steadily grows against the underlying GGBR token.
The Math Behind the Yield: The vault's exchange rate is calculated simply as total GGBR assets / total stGGBR supply. To ensure a reliable, fixed Annual Percentage Rate (APR), the system dynamically injects GGBR from a dedicated Yield Reserve into the vault.
Targeted Top-Ups: Every time a user interacts with the vault (such as depositing or withdrawing), the smart contract calculates the exact time elapsed since the last update. It then seamlessly pulls the required GGBR from the reserve to match the target APR, ensuring the vault is always fully collateralized and the exchange rate reliably increases.
Daily Injection = (totalAssets * targetAPY) / 365

Why Use an ERC-4626 Vault?
The core philosophy behind stGGBR is maximizing capital efficiency. By strictly adhering to the ERC-4626 standard and avoiding time-locked staking, stGGBR remains highly composable within the broader Decentralized Finance (DeFi) ecosystem.
Here is what you can do with stGGBR:
Collateral in Lending Markets: Because stGGBR is a standard liquid token that constantly appreciates in value, it serves as excellent collateral. You can supply stGGBR to money markets to borrow other assets, all while your underlying GGBR continues to earn its staking APR.
Liquidity Provision: stGGBR can be paired with other tokens in Decentralized Exchanges (DEXs) to earn trading fees on top of your staking yield.
Yield Aggregators: Other protocols can easily plug into the stGGBR vault to build complex, automated yield strategies without needing custom integration code.
