User wallet
Users hold their own assets and review and sign every exchange transaction themselves.
ABOUT SDBC
Digital value
built on clear rules.
SDBC is designed for one-to-one minting and redemption against USDT reserves on Arbitrum One. The official website does not custody assets; it helps your wallet call the smart contract directly.
OFFICIAL MODEL
A direct exchange model
between wallet and contract
SDBC minting and redemption are not handled by administrator approval or server-ledger changes. Transactions signed in the user wallet are executed by the StablePool contract under its fixed rules.
StablePool
The smart contract that holds USDT reserves and executes on-chain minting and redemption rules.
SDBC
A standard token sent to the user wallet when minted and burned in the same amount on redemption.

HOW IT WORKS
Minting and redemption
follow one connected rule.
MintUSDT → SDBC
- 01Connect your wallet and enter the amount of USDT to mint with.
- 02Sign the USDT approval and mint transaction in your wallet.
- 03StablePool receives USDT as reserves and mints SDBC.
- 04The minted SDBC is sent to the user wallet.
RedeemSDBC → USDT
- 01Enter the amount of SDBC to redeem.
- 02Sign the redemption transaction in your wallet.
- 03StablePool burns the redeemed SDBC.
- 04The corresponding amount of USDT is returned to the user wallet.
A 0.10% on-chain fee applies separately to minting and redemption. The deployed contract calculates the fee under its fixed rules.
DESIGN PRINCIPLES
Rules anyone can verify
come first.
One-to-one principle
SDBC cannot be minted without USDT deposited, and USDT redemption only occurs when SDBC is returned.
Non-custodial design
The website never stores or manages private keys, seed phrases, or user assets. All transaction signatures occur in the user wallet.
Minimal change surface
Core exchange rules and fees are fixed in the deployed contract. There is no arbitrary minting, withdrawal, or administrator approval.
VERIFIABLE INFORMATION
Verify the official path
on-chain.
Official minting and redemption are separate from external market trading. Official exchange follows the contract's one-to-one rule, while external prices, liquidity, and slippage depend on separate conditions.

BEFORE YOU USE
Before you begin
Your wallet, your responsibility
Only you should keep your wallet recovery phrase and private key. SDBC never requests or can recover them.
External transfers and bridges
SDBC can be transferred between wallets as a standard token. Cross-chain bridges are separate infrastructure and are outside the current official exchange scope.
Market price and risk
External market prices can vary with liquidity, demand, fees, and network conditions. This page does not guarantee returns or price appreciation.
