USDB
A USD‑denominated digital token created within the Blotix ecosystem. Blotix uses it to pay its platform clients, who can hold it, transfer it, or exchange it for USDT on Uniswap.
About
What USDB is
USDB is an ERC‑20 token on Ethereum issued by Blotix Fund LLC within the Blotix ecosystem. Blotix operates a platform where clients hold balances derived from real‑world‑asset tokenizations. When a client withdraws, Blotix pays the withdrawal in USDB: the client receives the tokens in their own Ethereum wallet, under their sole control, and can keep them, transfer them, or exchange them for USDT on the USDB/USDT Uniswap pool.
USDB is denominated in US dollars and is supported by USDT reserves held by the issuer. It is a means of payment for Blotix clients, not a product sold to the public. No guarantee of price stability is made and nothing on this site is investment advice.
Who can obtain USDB. USDB is issued only to clients of the Blotix platform as payment of their balances. It is not sold to the public, it is not an investment product and it should not be purchased with the expectation of profit. Third parties may still acquire it on the open market; the issuer does not promote or solicit such purchases.

The Blotix ecosystem
Blotix is a protocol for real‑world‑asset (RWA) tokenization with its own ERC‑20 token, BLOTIX, on Ethereum. USDB is the settlement token of that ecosystem: it lets clients receive the US‑dollar value of their balances in a form they can use anywhere on Ethereum.
Issuer controls
Issuance and redemption are executed from a Safe multisig owned by the issuer. The issuer can mint, burn, pause the token and freeze addresses in response to legal requirements — the same control model used by major USD tokens.

Process
How it works
Withdrawal request
A Blotix platform client requests to withdraw part or all of their balance.
Paid in USDB
The issuer sends the US‑dollar value of the withdrawal in USDB to the client's own Ethereum wallet.
Free to use
The client keeps it, transfers it, or exchanges it for USDT on the USDB/USDT Uniswap pool.
Reserves
Reserves and redemption
USDB is supported by USDT reserves held by the issuer. When Blotix pays clients in USDB, it supplies USDT liquidity to the USDB/USDT Uniswap V3 pool in line with the payments made, so that clients can exchange their USDB for USDT at any time without depending on the issuer's availability.
USDB that returns to the issuer can be burned, removing it from circulation. Supply is therefore not fixed: it expands when clients are paid and contracts when tokens are redeemed.
- Reserve asset: USDT (Tether) on Ethereum.
- Redemption path for clients: the USDB/USDT pool on Uniswap V3 (0.01% fee tier).
- Reserve reporting: on‑chain publication of the reserve address is planned once the treasury is fully migrated to the multisig (see roadmap). Until then, reserves are held by the issuer and not publicly attested.
USDB is denominated in US dollars but no guarantee of price stability is made. Its market price on Uniswap depends on the liquidity available in the pool at any given time.
Security
Security and transparency
Verified source code
The exact source code of the contract is published and verified on Etherscan, so anyone can read what the token does. The contract is built on OpenZeppelin Contracts 5.6.1, the most widely used Solidity library, with a small issuer layer on top.
Static analysis
The contract was analyzed with Slither (Trail of Bits, 102 detectors). No High‑ or Medium‑impact finding exists in the USDB contract; the only USDB‑specific result is a cosmetic naming note in the standard EIP‑2612 permit signature.
Full report · No independent third‑party audit has been performed yet.
Immutable and controlled
No proxy and no upgrade path: the code that runs today is the code that will always run. The issuer role cannot be renounced, so the token can never be left without a responsible issuer, and ownership changes require a two‑step transfer.
Compliance controls
Like USDT and USDC, the issuer can pause transfers and freeze specific addresses. These controls exist to respond to legal orders and security incidents; they are executed only from the issuer's Safe multisig and every use is visible on‑chain.

FAQ
Frequently asked questions
What is USDB used for?
Blotix uses USDB to pay its platform clients. When a client withdraws their balance, they receive the equivalent US‑dollar amount in USDB in their own Ethereum wallet.
Can I buy USDB?
USDB is not sold by the issuer to the public. It is issued only to Blotix clients as payment. Once in circulation it can be traded on Uniswap like any ERC‑20 token, but the issuer does not promote or solicit such purchases and USDB is not an investment product.
How do I convert USDB to USDT?
Through the USDB/USDT pool on Uniswap V3 (0.01% fee tier). Connect your wallet on app.uniswap.org, select USDB → USDT and swap. You need a small amount of ETH in your wallet to pay the network fee.
What backs USDB?
USDT reserves held by the issuer, Blotix Fund LLC. The issuer adds USDT liquidity to the Uniswap pool in line with the payments it makes in USDB. Reserves are not yet publicly attested; publishing the reserve address on‑chain is part of the roadmap.
Is USDB always worth exactly 1 USD?
USDB is denominated in US dollars and the pool is set up so that 1 USDB trades close to 1 USDT, but no guarantee of price stability is made. The market price depends on the liquidity in the pool at a given moment.
Which wallets support USDB?
Any Ethereum wallet that supports ERC‑20 tokens (MetaMask, Rabby, Ledger, Trust Wallet, etc.). If the token does not appear automatically, add it with the contract address 0xDAF05C8680A06a5A30A8e3Ffe25062eD4e4D21fB and 6 decimals.
Are there fees?
The token itself charges no transfer fee. Sending USDB costs the normal Ethereum network fee (gas), and swapping on Uniswap costs the pool fee (0.01%) plus gas.
Can the issuer freeze my tokens?
Yes. Like USDT and USDC, the contract lets the issuer pause transfers and freeze specific addresses. These controls are meant for legal orders and security incidents, are executed only from the issuer's multisig, and every use is recorded on‑chain.
There is another token called USDB. Is this the same?
No. Several unrelated tokens use the USDB symbol on different networks. Always check the contract address: the Blotix USDB is 0xDAF05C8680A06a5A30A8e3Ffe25062eD4e4D21fB on Ethereum mainnet.
Is the contract audited?
The source code is verified on Etherscan and has been analyzed with Slither (see Security). An independent third‑party audit has not been performed yet; it is part of the roadmap.
