BREAKING CHANGE:
- Crate `nssa` renamed to `lee`; update `Cargo.toml` dependencies from `nssa = { workspace = true }` to `lee = { workspace = true }`.
- Crate `nssa_core` renamed to `lee_core`; update similarly.
- Crate `key_protocol` moved under `lee`; update `Cargo.toml` dependencies from `key_protocol = { workspace = true }` to `lee_key_protocol = { workspace = true }`.
- Type `NSSATransaction` (in `common`) renamed to `LeeTransaction`.
- Error type `nssa::error::NssaError` renamed to `lee::error::LeeError`.
- Error type `nssa_core::error::NssaCoreError` renamed to `lee_core::error::LeeCoreError`.
- All `use nssa::` and `use nssa_core::` import paths must be updated to `use lee::` and `use lee_core::` respectively.
- Guest programs must replace `write_nssa_outputs` with `write_lee_outputs`.
- The sequencer RocksDB column family for the chain state was renamed. Existing databases are incompatible and must be wiped before running the new version.
- Domain separators updated: `"NSSA_seed"` → `"LEE_seed"` (key derivation), `"NSSA/v0.2/KDF-SHA256/"` → `"LEE/v0.2/KDF-SHA256/"` (encryption KDF), `"/NSSA/v0.2/AccountId/PDA/"` →
`"/LEE/v0.2/AccountId/PDA/"` (public PDA address derivation). All previously derived keys, encrypted outputs, and public PDA addresses are invalidated.
Introduce the ATA program, which derives deterministic per-token holding
accounts from (owner, token_definition) via SHA256, eliminating the need
to manually create and track holding account IDs.
Program (programs/associated_token_account/):
- Create, Transfer, and Burn instructions with PDA-based authorization
- Deterministic address derivation: SHA256(owner || definition) → seed → AccountId
- Idempotent Create (no-op if ATA already exists)
Wallet CLI (`wallet ata`):
- `address` — derive ATA address locally (no network call)
- `create` — initialize an ATA on-chain
- `send` — transfer tokens from owner's ATA to a recipient
- `burn` — burn tokens from owner's ATA
- `list` — query ATAs across multiple token definitions
Usage:
wallet deploy-program artifacts/program_methods/associated_token_account.bin
wallet ata address --owner <ID> --token-definition <DEF_ID>
wallet ata create --owner Public/<ID> --token-definition <DEF_ID>
wallet ata send --from Public/<ID> --token-definition <DEF_ID> --to <RECIPIENT> --amount 100
wallet ata burn --holder Public/<ID> --token-definition <DEF_ID> --amount 50
wallet ata list --owner <ID> --token-definition <DEF1> <DEF2>
