At most four calls. #### Parameters | Parameter | Type | | --------- | ------------------------------------------- | | `ref` | [`SessionRef`](#sessionref) & `object` | | `reader` | [`EvmReader`](https://lcp.integraledger.com/reference/api/evm#evmreader) | #### Returns `Promise`\<[`SessionStatus`](#sessionstatus)> *** ### tie() > **tie**(`options`): \[`"mpp"`, \{ `challenges`: [`MppChallenge`](#mppchallenge)\[]; }] The binding slot: the distinct challenges among `options`, each with exactly MPP's bound members, as issued. #### Parameters | Parameter | Type | | --------- | ------------------------------------------- | | `options` | readonly [`MppChallenge`](#mppchallenge)\[] | #### Returns \[`"mpp"`, \{ `challenges`: [`MppChallenge`](#mppchallenge)\[]; }] *** ### transferPresent() > **transferPresent**(`ref`, `reader`): `Promise`\<[`EvmBreadthStatus`](https://lcp.integraledger.com/reference/api/evm#evmbreadthstatus)> `evmStatus` on the reported transaction with no named log; settled also requires one log from `ref.asset` with three topics and `topics[0]` = `Transfer`, else failed `transfer-not-found`. At most three calls. #### Parameters | Parameter | Type | | --------- | ------------------------------------------------ | | `ref` | [`EvmRef`](https://lcp.integraledger.com/reference/api/evm#evmref) & `object` | | `reader` | [`EvmReader`](https://lcp.integraledger.com/reference/api/evm#evmreader) | #### Returns `Promise`\<[`EvmBreadthStatus`](https://lcp.integraledger.com/reference/api/evm#evmbreadthstatus)> *** ### usdcGatewaySalt() > **usdcGatewaySalt**(`i`): `` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal) `usdc`'s Gateway salt: keccak256 of the JCS of the inputs with `method` "usdc", `intent` "charge", `type` "gateway". #### Parameters | Parameter | Type | | --------- | --------------------------------------- | | `i` | [`GatewaySaltInput`](#gatewaysaltinput) | #### Returns `` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal) *** ### usdcNonce() > **usdcNonce**(`id`, `realm`, `requestHash`): `` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal) `usdc`'s EIP-3009 nonce: keccak256 of the JCS of `{id, method: "usdc", realm, intent: "charge", requestHash}`, with `requestHash` written as `0x` and 64 lowercase hex. #### Parameters | Parameter | Type | | ------------- | ------------------- | | `id` | `string` | | `realm` | `string` | | `requestHash` | `` `0x${string}` `` | #### Returns `` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal) *** ### usdcRequestHash() > **usdcRequestHash**(`requestParam`): `Promise`\<`` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal)> keccak256 of the challenge's `request` parameter's decoded bytes, as `0x` and lowercase hex. The bytes must be the RFC 8785 form of their own parse, else `mpp/request-not-jcs`; they are hashed as received. #### Parameters | Parameter | Type | | -------------- | -------- | | `requestParam` | `string` | #### Returns `Promise`\<`` `0x${string}` `` | [`Refusal`](https://lcp.integraledger.com/reference/api#refusal)> ## References ### chargeHedera Re-exports [chargeHedera](https://lcp.integraledger.com/reference/api/hedera#chargehedera) *** ### pairingsOfPlaced Re-exports [pairingsOfPlaced](https://lcp.integraledger.com/reference/api#pairingsofplaced) *** ### ReceiveTypedData Re-exports [ReceiveTypedData](https://lcp.integraledger.com/reference/api/evm#receivetypeddata)
