TypeScript SDK: AccountAddress

Purpose

Guide correct creation, parsing, and formatting of account addresses in @aptos-labs/ts-sdk. Addresses are 32-byte values; string format follows AIP-40.

ALWAYS

1. Use AccountAddress.from() for flexible input – accepts string (with or without 0x), Uint8Array, or existing AccountAddress.
2. Use addresses as AccountAddress or string in API – SDK accepts AccountAddressInput (string or AccountAddress) in most APIs.
3. Use AccountAddress.fromStringStrict() / AccountAddress.fromStrict() when you need AIP-40 strict: LONG (0x + 64 hex chars) or SHORT only for special (0x0–0xf).
4. Use derived address helpers from the SDK for object/resource/token addresses – do not hand-roll hashing.
