Frequently Asked Questions

Common questions about Brtr Protocol.

General

What is Brtr?

Brtr is a trustless OTC execution protocol for fixed-price peer-to-peer token trades. Smart-contract escrow and LayerZero messaging handle cross-chain settlement.

How is Brtr different from DEXs?

Is Brtr custodial?

No. Brtr is fully non-custodial. Tokens are held in smart contracts during trades, never by the Brtr team or any third party.

Which chains does Brtr support?

Currently (testnet):

• Base Sepo
• OP Sepo
• Monad Testnet
• MegaETH

Additional chains are evaluated after testnet validation.

Trading

How do I create an order?

1. Connect your wallet
2. Go to "Create Order"
3. Select token and amount to offer
4. Add payment options (tokens you'll accept)
5. Review and confirm

See Creating Orders for detailed guide.

How do I fill an order?

1. Browse the Discover page
2. Find an order you want to fill
3. Select a payment option
4. Click "Fill Order" and confirm

See Filling Orders for detailed guide.

Can I partially fill an order?

No. Brtr currently supports full fills only. The entire order amount must be filled in one transaction.

Can I edit my order after creating it?

No. Orders cannot be edited once created. You can cancel and create a new order with different terms.

How long do cross-chain trades take?

Typically 3-6 minutes, depending on network conditions. LayerZero messages usually arrive within 2 minutes per hop.

What if my cross-chain trade gets stuck?

Wait up to 30 minutes. If still stuck:

• Check LayerZero Scan (opens in a new tab) for message status
• Use recovery functions (available after 30-min timeout)
• Contact support in Discord (opens in a new tab)

Fees

What are the fees?

• Seller fee: 0.5% of offer tokens
• Buyer fee: 0.3% of payment tokens
• Gas fees: Network-dependent

When are fees charged?

Only on successful trades. No fees for:

• Creating orders
• Cancelling orders
• Failed transactions

Who receives the fees?

Protocol treasury, used for development and operations.

Technical

How does cross-chain trading work?

Brtr uses LayerZero for cross-chain messaging:

1. Buyer initiates fill, tokens escrowed
2. Message sent to seller chain, tokens locked
3. Confirmation sent back, buyer tokens released
4. Finalization sent, seller tokens released

See Cross-Chain Flow for details.

Is the code open source?

Yes! Smart contracts and frontend are open source:

• github.com/brtr-protocol (opens in a new tab)

What tokens can I trade?

Any ERC-20 token on supported chains. No listing required.

Troubleshooting

Transaction failed - why?

Common reasons:

• Insufficient gas
• Token approval needed
• Order already filled/cancelled
• Network congestion

I don't see my order after creating it

• Ensure transaction confirmed
• Refresh the page
• Check correct network is selected

Cross-chain fill stuck in pending

1. Check LayerZero Scan for message status
2. Wait up to 30 minutes
3. Use recovery functions if timeout passed
4. Contact support if still stuck

Tokens not received after trade

• Verify transaction completed successfully
• Check correct wallet address
• For cross-chain: wait for all 3 messages
• Check block explorer for token transfers

Security

Is my wallet safe?

Brtr only requests:

• Token approvals (for specific amounts)
• Transaction signatures

We never ask for:

• Private keys
• Seed phrases
• Unlimited approvals

What happens if Brtr shuts down?

• Your tokens in open orders are always recoverable
• In-progress trades will complete automatically
• Smart contracts are immutable

How do I report a security issue?

Email security@brtr.world with details. Do not disclose publicly. See Contract Addresses.
