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