URI Standards

Before storing a URI string in a Cell, URIs must be prefixed with 8-bit off-chain content prefix (0x01) to be rendered correctly on TONscan and NFT marketplaces.

const OFFCHAIN_CONTENT_PREFIX = 0x01;
const uriString = "https://...";
let uriInputParam = beginCell()
	.storeInt(OFFCHAIN_CONTENT_PREFIX, 8)
