Common Mistakes

Top 6 mistakes AI agents make

  1. Using Network.TESTNET — Use Network.MAINNET (Vector testnet uses mainnet network ID)
  2. Using old Aiken v1.0.29-alpha — Use latest stable (v1.1.x+), Vector is Conway era
  3. Targeting PlutusV2 — Use PlutusV3 (Vector runs Conway era)
  4. Using addr_test1 addresses — Vector uses addr1 for both testnet and mainnet
  5. Definite-length CBOR — Use indefinite-length arrays to match Aiken encoding
  6. Assuming decoded datums — Ogmios returns raw CBOR hex, decode with cbor2
