multi inputs & multi outputs

[xhliu]

for stateless & stateful contracts, similar to https://github.com/sCrypt-Inc/scrypt-ord/blob/master/tests/contracts/ftCounter.ts.

Just use multiCall?

transfer(inputInstances, outputInstances, signer)

This is mostly about multi inputs, e.g., multi call to contracts. So just make it similar to https://docs.scrypt.io/advanced/how-to-call-multiple-contracts, using partial tx.

Rename multi.spec.ts to multiInput.spec.ts.

Typo ordp2kh -> ordp2pkh
https://github.com/sCrypt-Inc/scrypt-ord/blob/master/tests/specs/multi.spec.ts#L21

[xhliu]

Use instance.methods.unlock to transfer

scrypt-ord/tests/specs/multi.spec.ts

Lines 39 to 43 in dba56bc

	const { tx, nexts } = await OrdP2PKH.transfer(
	ordP2PKHs,
	signer,
	recipients
	)

Also I thought we removed nexts in return #3 (comment).

Above does not work for non-OrdP2PKH contracts. What if there is a P2PKH, hashpuzzle, or counter input each?

Merge these two into
dummyBsv20(..., prepend: boolean =false).

scrypt-ord/tests/specs/utils.ts

Lines 5 to 16 in dba56bc

	export function dummyAppendbsv20(addr: bsv.Address, tick: string, amt: bigint) {
	return {
	script: bsv.Script.buildPublicKeyHashOut(addr)
	.add(Ordinal.createTransfer(tick, amt))
	.toHex(),
	satoshis: 1,
	txId: randomBytes(32).toString('hex'),
	outputIndex: 0,
	}
	}
	export function dummyPrependbsv20(

Same for

scrypt-ord/tests/specs/utils.ts

Lines 31 to 45 in dba56bc

	export function dummyPrependNFT(addr: bsv.Address, text: string) {
	return {
	script: Ordinal.create({
	content: text,
	contentType: 'text/plain',
	})
	.add(bsv.Script.buildPublicKeyHashOut(addr))
	.toHex(),
	satoshis: 1,
	txId: randomBytes(32).toString('hex'),
	outputIndex: 0,
	}
	}
	export function dummyAppendNFT(addr: bsv.Address, text: string) {
