constructor

new CrossChainPaymentRouter(
signer: BridgeSigner,
sourceChain: string,
): CrossChainPaymentRouter
Create a cross-chain payment router
Parameters
- signer: BridgeSigner
  Wallet signer for bridge operations
- sourceChain: string
  Chain where user's funds are located
Returns CrossChainPaymentRouter
- Defined in mechanisms/evm/src/bridge/router.ts:55

Methods

`Static`getBridgeableChains

getBridgeableChains(): string[]
Get all bridgeable chains

Returns string[]
Array of all chain names that support USDT0 bridging
- Defined in mechanisms/evm/src/bridge/router.ts:66

routePayment

routePayment(params: CrossChainPaymentParams): Promise<CrossChainPaymentResult>
Route payment across chains

This method:
1. Bridges USDT0 from source chain to destination chain
2. Sends funds to the payer's address on destination chain
3. Returns tracking info for monitoring delivery
After delivery, the payer can use the bridged funds to pay on the destination chain.
Parameters
- params: CrossChainPaymentParams
  Payment routing parameters
Returns Promise<CrossChainPaymentResult>
Result with transaction hash and tracking info
- Defined in mechanisms/evm/src/bridge/router.ts:83

estimateFees

estimateFees(
    params: CrossChainPaymentParams,
): Promise<
    {
        nativeFee: bigint;
        estimatedReceiveAmount: bigint;
        estimatedTime: number;
    },
>
Get estimated fees for routing a payment
Parameters
- params: CrossChainPaymentParams
  Payment parameters
Returns Promise<
    {
        nativeFee: bigint;
        estimatedReceiveAmount: bigint;
        estimatedTime: number;
    },
>
Quote with native fee and estimated receive amount

waitForDelivery

waitForDelivery(
messageGuid: string,
options?: WaitForDeliveryOptions,
): Promise<LayerZeroMessage>
Wait for payment to be delivered on destination chain
Parameters
- messageGuid: string
  LayerZero message GUID from routePayment result
- Optionaloptions: WaitForDeliveryOptions
