Providers

The three rails YiFi Swap routes across, and the providers behind each.

On-chain (DEX aggregation)

• Cross-chain routes are multi-step and not atomic; they combine bridging and swapping across networks.

• MEV and front-running protection is available on this rail (for example via CoW Swap), which matters for larger trades.

• Token approvals are resolved per route, including intermediate contracts used by some aggregators and explicit allowance-spender handling where required.

On-chain providers

• LI.FI

• Rango Exchange

Off-chain (CEX aggregation)

• Widest coverage. The broadest range of assets and chains, including non-EVM networks.

• No wallet connection, no gas required from the user, which lowers the barrier for embedded and non-DeFi surfaces.

Off-chain providers

• Quickex

• ChangeNow

• SwapGate

• SimpleSwap

• Letsexchange

• FixedFloat

Because off-chain routes involve a third-party exchanger, that provider may run its own KYC and impose its own limits. See KYC Labels.

Private

Two Off-chain providers are used – one per exchange leg.

• Private (XMR-hop) – an intermediate hop in Monero.

• Stealth (stable-hop) – a stablecoin hop, removing volatility.

See Private Swaps to learn more of how it work under the hood.

KYC Labels

Some routes, particularly off-chain (CEX), pass through providers that may run their own identity verification. To help users choose, the interface can display a KYC Label indicating the verification regime a given provider applies on its own side.

What a KYC Label is

• An informational indicator of the identity-verification regime a provider is expected to apply.

• Attached per provider, so users can weigh a route before selecting it.

and what KYC label is not:

• It is not a guarantee. A provider can change its process, request documents, or apply verification at its own discretion.

• It is not YiFi performing KYC. YiFi Swap does not itself run identity verification or collect KYC data from users.

• It is not advice or an endorsement of any provider.

Where KYC happens

When a user transacts through an off-chain provider, the relationship is directly with that provider under its own terms. That provider, not YiFi, may perform KYC: request documents, impose limits, and freeze, delay, reject, or reverse a transaction.

On-chain (DEX) routes are non-custodial and generally do not involve provider-side KYC, though users remain responsible for their own legal and regulatory compliance.

KYC Labels are indicative only. Always direct users to the selected provider's own terms for the authoritative verification requirements. YiFi's overall compliance approach is described in the AML/KYC Compliance policy.

Provider risk

Routing across third-party providers carries risks the integrator should surface to users:

• Smart-contract / router risk on the on-chain rail – third-party routers can contain bugs or be exploited.

• Off-chain provider risk – an exchanger may require KYC and can freeze, delay, or reject a transaction under its own terms.

• Execution risk – quotes are indicative and the final outcome depends on slippage, route availability, and network or bridge conditions.
