Address format

A 32-byte hash in unpadded base64url, 43 characters, with the two unused bits of the last digit required to be zero. That's why the last character can only be one of AEIMQUYcgkosw048. The optional :checksum suffix isn't supported and an address carrying one is rejected.

Transaction IDs are the same 32 bytes in the same encoding, so a string that fits could be either. This check tells you it's a well formed Arweave identifier, not that it's a wallet.

import { getChain } from "@agntn/chains";

const chain = getChain("ar");
chain.assertAddress("kY9RAgTJEImkBpiKgVeXrsGV02T-D4dI3ZvSpnn7HSk"); // returned unchanged
chain.type; // "arweave"
chain.caip2; // "arweave:7wIU"
