**Short answer (November 10, 2026):** Script Master Labs publicly documents five network payment routes across two facilitators: OMNIGATE handles **Base and Arc**, while 402Proof handles **Solana, XRP Ledger, and Xahau**. A *route* is not the same thing as a *token*: USDC appears on multiple networks; XRP and XAH are native assets on different networks; and RLUSD is part of a separately documented 402Proof invoice workflow. The published facilitator fee varies by route, so there is no honest universal five-rail fee.

| Route | Facilitator | Published payment asset / mode | Published facilitator tariff | Important boundary | 
|---|---|---|---|---|
| Base ( `eip155:8453` ) | OMNIGATE | USDC, x402 exact | **0.005 USDC per settlement** , waived for fee-less payments within a stated daily allowance | 500 across all payTos and 100 per payTo, UTC; otherwise a fee leg is needed or fee-less requests are refused | 
| Arc ( `eip155:5042` ) | OMNIGATE | USDC, x402 exact | Same 0.005 USDC model | Confirm the fresh offer's Arc network and receiver | 
| Solana mainnet | 402Proof | USDC over Solana, standard sidecar | **0.005 USDC per settlement** | Published as separate in-transaction facilitator transfer; do not confuse **USDC on Solana** with native**SOL** | 
| XRP Ledger ( `xrpl:0` ) | 402Proof standard v2 | Native XRP / exact | **USD $0.0100 per completed settlement, accrued to merchant** | Public terms say automatic collection was not live; loyalty reductions depend on prior successful settlements | 
| Xahau ( `xrpl:21337` ) | 402Proof | Native XAH / exact | **0.01 XAH per third-party settlement** | A fee denominated in XAH is not a fixed USD charge | 

The fee table summarizes **Script Master Labs' published terms**, verified live on 2026-11-05 against the facilitators' own published terms; it is not a fresh production settlement audit. The relevant first-party records are the [facilitator seller page](https://scriptmasterlabs.com/settle-through-sml), [offer/fee ledger](https://scriptmasterlabs.com/payment-offers) and [dated quote-provenance page](https://scriptmasterlabs.com/cite-proof). At request time, the fresh challenge and the applicable onboarding agreement control.

The published OMNIGATE base facilitator tariff is **0.005 USDC**. A standard payment *without* a fee leg can settle with its facilitator fee waived while the operator's daily budget remains available. The published limits are **500 settlements per UTC day across all payTos** and **100 per payTo**. After the relevant allowance, a fee-less payment is refused until reset; a compatible payment including the fee leg can settle and pay it. Merchant route pricing is separate from this facilitator tariff.

The standard XRPL 402Proof tariff is described as **USD $0.0100 accrued**, not a $0.0100 charge automatically withdrawn on-chain. The public schedule reduces it to $0.0080 after 100 prior settlements, $0.0070 after 1,000, and $0.0050 after 10,000. That distinction matters to agents and merchants building accurate reconciliation. It is different from the legacy/invoice workflow, which publishes a **0.01 fee denominated in the invoice asset**, including RLUSD where supported. Do not mix their fee statements.

These are **five network routes**, not an assertion that every route accepts five assets. In particular:

When a product says “five rails,” demand the actual combinations of `(scheme, network, asset, payTo)` rather than counting product names or logos.

The total spend estimate should state **merchant's resource price + applicable facilitator fee + any known network-related or service charges**, identifying who actually bears each component. Quote in the required asset and network; never silently convert XAH or XRP fee amounts into stable USD without a dated rate and conversion method. A facilitator fee that is *accrued* is not the same thing as an on-chain debit. A publicly quoted route is not proof that a particular settlement has succeeded today.
