Balance approvals

Use balance approvals to share balances between multiple addresses. This helps to onboard users without requiring them to own tokens.

With balance approvals:

You pay for transactions.
Users sign transactions.

Balance approvals:

Are based on the token set when connecting to an Irys node. Both approver and approvee must use the same token.
Are registered instantly upon upload completion.
Are non-transferable.
Can be configured to expire automatically.

Create an approval

To update an existing approval, create a new approval with the same address (it will overwrite the existing approval).

const receipt = await irys.approval.createApproval({
	amount: irys.utils.toAtomic(1), // Amount in atomic units
	approvedAddress: "<address>",
	expiresInSeconds: 100, // Expires in 100 seconds. Delete to remove expiration.
});

Upload using an approval

const receipt = await irys.upload("GM World", { upload: { paidBy: "<address>" } });

Combine approvals and tags:

const uploadOptions = {
	upload: {
		paidBy: "<address>",
	},
	tags: [{ name: "Content-Type", value: "text/plain" }],
};
const receipt = await irys.upload(dataToUpload, uploadOptions);

Revoke an approval

const receipt = await irys.approval.revokeApproval({ approvedAddress: "<address>" });
