- replace unverified 'lgs wallet -- token' subcommands with the same spel invocations as demo-full-flow.sh (correct flags, base58->hex authority) - use the new --authority-account signer model - remove misleading || true error-swallowing and false 'verified' claims; point to the unit/integration tests that actually prove the guarantees

# LP-0013 Example: Fixed Supply Token
|
|
#
|
|
# Demonstrates, against a real LEZ sequencer via spel:
|
|
# - creating a fungible token with a mint authority
|
|
# - minting additional supply (authority-gated)
|
|
# - permanently revoking the mint authority (fixed supply)
|
|
#
|
|
# After revocation, AuthoritySlot rejects any further mint. That guarantee is
|
|
# covered by:
|
|
# - token_program unit tests: mint_with_revoked_authority_fails,
|
|
# set_authority_on_revoked_fails
|
|
# - integration test: token_set_authority_revoke
|
|
# Run them with: RISC0_DEV_MODE=0 cargo test -p token_program -p lez-authority --lib
|
|
#
|
|
# Usage (from inside an lgs scaffold project dir):
|
|
# RISC0_DEV_MODE=0 bash <path-to-lez-programs>/scripts/examples/fixed_supply_token.sh
