Frequently Asked Questions

Everything you need to know about TBillUSD

General

What is TBillUSD (TBUSD)?
TBillUSD is a USD-pegged stablecoin backed by U.S. Treasury securities and cash equivalents. It's designed for fast, low-cost payments with built-in protection features like cross-chain recovery.
What blockchain is TBUSD on?
TBUSD is deployed on Base, an Ethereum Layer 2 network built by Coinbase. Base offers fast transactions (~2 seconds) and low fees while inheriting Ethereum's security.
What is the contract address?

The official TBUSD contract on Base mainnet is:

0xA2a61C3E298EB7Ef510757B4eD388C793E1A5b4c

Always verify this address before transacting. You can view it on BaseScan.

How do I buy TBUSD?

TBUSD is available on decentralized exchanges:

  • Uniswap - Swap USDC or ETH for TBUSD
  • Aerodrome - Swap USDC for TBUSD

We do not sell TBUSD directly. All tokens enter circulation through DEX liquidity pools.

Reserves & Backing

What backs TBUSD?

TBUSD is backed by:

  • BENJI tokens - Franklin Templeton's OnChain U.S. Government Money Fund (FOBXX), invested in U.S. Treasury securities
  • USDC - On-chain stablecoin reserves
  • Cash equivalents - Bank accounts and money market funds
How can I verify the reserves?

Visit our Reserves page to see real-time on-chain balances. All USDC holdings are verifiable on BaseScan. Our ProofOfReserves contract is linked to the TBUSD token and can be audited on-chain.

What is the ProofOfReserves contract?
TBUSD has a linked ProofOfReserves contract that requires attestation before minting. This prevents minting more tokens than reserves support. Attestations expire after 30 minutes, requiring regular verification.

Cross-Chain Recovery

What if I send TBUSD to the wrong network?

Unlike most tokens, TBUSD can be recovered if sent to the wrong network. Our cross-chain recovery service allows you to prove ownership of the stuck funds and receive replacement tokens on the correct network.

Visit our Recovery page to initiate a recovery request.

What are the recovery fees?
  • 0.1% fee - If you control the wallet (can sign a message proving ownership)
  • 2% fee - For CEX addresses or wallets you don't control (requires KYC verification)

Gas costs are covered by the recovery fee.

How long does recovery take?
Recovery is a manual process. After submitting your request and proof of ownership, our team reviews and processes the recovery. Typical turnaround is 1-3 business days, though complex cases involving CEX addresses may take longer.

Gasless Transfers

What are gasless transfers?
Gasless transfers allow you to send TBUSD without holding ETH for gas fees. You sign a message authorizing the transfer, and our relayer submits the transaction and pays the gas on your behalf.
Is there a fee for gasless transfers?
No. Gasless transfers are free for all users. We pay the gas costs (~$0.001 per transaction on Base).
How do I use gasless transfers?
Visit our Transfer page, connect your wallet, enter the recipient address and amount, then sign the message. Our relayer will submit the transaction for you.

Security

Is TBUSD audited?
TBUSD uses battle-tested OpenZeppelin contracts for its core functionality (ERC20, upgradeable proxy, access control). The custom features (recovery, proof of reserves) have been thoroughly tested with 100% code coverage.
Who controls the TBUSD contracts?

TBUSD is controlled by two multisig wallets:

  • Operations Safe - 2-of-3 multisig for daily operations (minting, transfers)
  • Governance Safe - 2-of-3 multisig for upgrades and administrative changes

Both require multiple hardware wallet signatures for any action.

Is TBUSD upgradeable?
Yes, TBUSD uses a UUPS proxy pattern allowing bug fixes and feature additions. Upgrades require approval from the Governance Safe (2-of-3 multisig with hardware wallets). The proxy address remains constant, so your tokens are always at the same address.
