Scheduling

import {createClient} from '@fuzd/client';

const client = createClient({privateKey, schedulerEndPoint: 'https://fuzd.example'});
const remoteAccount = await client.assignRemoteAccount('1');

// one transaction
await client.scheduleExecution({
	slot,
	chainId: '1',
	transaction: {to, data, gas: 100_000n},
	maxFeePerGasAuthorized,
	timing: {type: 'fixed-time', scheduledTime},
});

// several transactions in one submission: broadcast in this order, from the same remote account
await client.scheduleExecution({
	slot,
	chainId: '1',
	transactions: [
		{to, data: first, gas: 100_000n},
		{to, data: second, gas: 150_000n},
	],
	maxFeePerGasAuthorized,
	timing: {type: 'fixed-time', scheduledTime},
	paymentReserve: {amount, broadcaster: remoteAccount.address},
});

The slot, timing, maxFeePerGasAuthorized (the most each transaction may pay per gas), paymentReserve, onBehalf and inClear belong to the submission and apply to all of its transactions. Unless inClear is set, the whole list is time-locked together. Each transaction of a batch is then readable at its index (/api/execution/execution/:chainId/:account/:slot/:batchIndex).

computeTotalMaxCost and computeBalanceRequired take either {maxFeePerGasAuthorized, gas, value?} or {maxFeePerGasAuthorized, transactions}. For a batch the cost is the sum over its transactions of gas * maxFeePerGasAuthorized, plus the service's fees on that (charged per transaction, as the executor charges each broadcast), plus the transaction's value.
