Fees & Settlements
Our payment infrastructure adopts a transparent Path-based fee structure.
The system automatically calculates fees based on the routing distance between the asset paid by the user and the asset received by the merchant. No matter how complex the path, all fees are calculated and deducted at the time of payment, and the net amount received by the merchant is the settlement amount.
Fee Structure
Fees are determined solely by the Payment Path and are fixed once the path is selected, typically ranging from 0.2% to 0.6%.
All fees are transparently charged as a percentage of the payment amount. There are no additional fees such as network fees, withdrawal fees, or hidden charges.
| Scenario | Path Example | Fee Rate | Description |
|---|---|---|---|
| Same-Chain Payment | USDT (Polygon) → USDT (Polygon) | 0.2% | Same token on the same chain. Only basic transfer consolidation costs. |
| Same-Chain Swap | USDC (Polygon) → USDT (Polygon) | 0.3% | Different tokens on the same chain. Includes on-chain DEX swap costs. |
| Cross-Chain Payment | USDC (Arbitrum) → USDT (Polygon) | 0.6% | Different chains. Includes cross-chain bridge gas fees and liquidity costs. |
In API returned data, fees use PPM (Parts Per Million) units.
For example: feeRatePPM: 6000 represents 6000 / 1000000 = 0.006, i.e., 0.6%.
Settlement Rules
Since we adopt a Non-custodial Architecture, the settlement process is real-time and automated.
- Settlement Cycle: T+0. Typically within 30-40 seconds after payment success, funds will directly reach your wallet.
- Fund Flow: User Wallet -> Smart Routing Contract -> Merchant Wallet. The platform holds no funds.
- Network Fees: Gas fees generated by consolidation and settlement are included in the above handling fees; merchants do not need to prepare extra ETH/MATIC as Gas.
Payment Capabilities Table
The following table displays currently supported settlement assets, payment paths, and corresponding limit configurations.
Transaction Limits
Same-chain Settlement Limits:
- $0.50 ~ $50,000.00 - Applies to all same-chain payment scenarios.
Cross-chain Settlement Limits (by receiving chain):
- Ethereum (ETH): $3,500 ~ $50,000
- Arbitrum (ARB): $10 ~ $50,000
- Base: $5 ~ $50,000
- Polygon (POL): $20 ~ $50,000
Transactions outside these ranges will be rejected to ensure optimal routing efficiency and cost coverage.
