The numbers, made clear.
A practical reference for minimum trade sizes, disclosed fees, gas, and amount protection.
Minimum sell amounts
| Token | Minimum sell amount |
|---|---|
| ETH or WETH | 0.00001 token |
| USDG | 0.01 token |
| Custom ERC-20 with 6 or more decimals | 0.000001 token (one-millionth) |
| Custom ERC-20 with fewer than 6 decimals | 1 base unit (its smallest on-chain unit) |
There is no product-level maximum. A trade still has to fit your wallet balance, native gas reserve, available route liquidity, output bounds, provider acceptance, simulation, and the EVM’s numerical range.
Swap fees
| Cost | How it works |
|---|---|
| FeatherFi integrator fee | 15 basis points (bps), or 0.15%, disclosed in the quote. |
| Independent 0x fee | A separate provider fee. It may use the other token in the pair and is not collected by FeatherFi. |
| Network gas | Paid by your wallet for every approval and swap action. The quote includes an estimate. |
The trade review lists the FeatherFi fee, 0x fee, and estimated network cost separately in their own tokens. It does not add ETH and another token into a combined fee amount. Approval transactions have their own gas cost, shown by your wallet.
Liquidity fees and protection
The documented LP v1 plan currently has no FeatherFi liquidity-action fee. The fixed WETH/USDG pool has a nominal 0.30% Uniswap fee. Pool fees and network gas are separate from any interface fee.
An accepted LP plan uses 50 bps (0.50%) amount protection. Plans above 100 bps (1.00%) are rejected. This protection is separate from the pool’s trading fee.
What displayed values mean
A displayed balance, preview, route, quote, amount, fee, or position is not a promise of execution or preserved value. Every action still needs a valid current route or plan and successful checks.
FeatherFi may pause access or tighten policy during an incident. Quotes expire after 15 seconds, and you pay network gas for each approval or action your wallet submits.
