Smart Contracts

Phantasma supports VM smart contracts. In the current toolchain, contracts are authored in TOMB source files and compiled with pha-tomb.

Smart-contract workflows fall into two broad groups:

• standalone custom contracts

• token-backed contracts bound to an uppercase token symbol

Deployment flows

• standalone lowercase custom contract -> deploy with contract deploy

• new uppercase token-backed contract -> create with --create-token

• existing token + new VM code -> contract attach

• later contract code update -> contract upgrade

For the current deployment tooling:
