How a swap works

A fixed-rate swap from post to payout. Amounts below are illustrative at the public 0.20% per-side fee.

Step 01
Post or pick an offer
A maker posts an exact pair — for example 100 BARTER for 50 USDC. You can accept as posted or propose a signed counter.
Step 02
Open escrow
Once terms are agreed, the maker cancels the open listing if needed and both wallets deposit the agreed amounts into the on-chain escrow contract.
Step 03
Deposit your side
Each party approves and deposits only what the deal requires. Wallet review stays explicit — Barter never holds your keys.
Step 04
Receive your tokens
When both deposits land, escrow releases atomically. Each side keeps roughly 99.8% of what they receive after the 0.20% protocol fee on that leg.

Worked example · 0.20% per side

Each party pays 0.20% on what they receive, not one fee split between you.

100 BARTER ↔ 50 USDC

Buyer fee (0.20% on BARTER received):0.2 BARTER
Seller fee (0.20% on USDC received):0.1 USDC
Buyer receives:99.8 BARTER
Seller receives:49.9 USDC

~0.40% combined on balanced swaps. Each side pays the same rate on what they get. Stakers pay their tier rate instead.

Token status

$BARTER is minted and held securely. Staking for fee discounts is planned for a future phase. The app is live with 0.2% flat fees.

Trust and workflow

Post exact terms, counter if needed, then settle through the same verified escrow contracts. Wallet review stays explicit, and price lookups never block the trading flow.

Wallets often flag new verified contracts as "untrusted." That is normal for a fresh deployment. Review the contract address and exact amounts in your wallet before approving. View verified escrow on Basescan
