The Blockchain Abstraction Layer (BAL) decouples protocol execution semantics from any particular settlement network. Identical commercial and security meanings can operate across multiple chains.
Why abstraction
- Avoid locking logistics semantics to a single L1/L2
- Allow settlement rails to upgrade without rewriting PAEE
- Support interoperability for JIT security and J1USD settlement
- Keep enterprise integrations focused on protocol events, not chain quirks
Live chain today
BNB Smart Chain is where official JIT and J1USD live now. BAL says that fact is a deployment choice. Custody still means custody if settlement later spans more rails. Users adding tokens must still use the live BNB Smart Chain addresses documented in J1USD and JIT articles.
What stays chain-agnostic
DLA identity, PAEE transitions, ACE recommendations, and oracle-as-bridge rules are protocol meaning. Gas tokens, explorer UIs, and wallet import screens are deployment details. Do not import J1USD using another chain’s decimals because BAL exists as an idea.
