Steps

  1. Create an apt or sui endpoint.
  2. Aptos: start from ledger info / latest version methods documented under /apt (REST-style or JSON-RPC depending on catalog entry).
  3. Sui: sui_getLatestCheckpointSequenceNumber then sui_getTransactionBlock.
  4. Always pass the encoding/options objects shown in the method docs.

Tips

  • Move object IDs and addresses are not EVM 0x accounts — use each chain’s explorers for sample digests.
  • Open /apt and /sui in the sidebar for full method + credit tables.
