Ticker symbols on Archr are free-for-all by default: two launches can each ship a PEPE, and the contract address is always the real identifier. The exception is the disabled-ticker registry. The factory keeps an on-chain list of disabled tickers, and a launch whose symbol is on it reverts; this is enforced by the contract, on every launch surface. ARCHR is on the list from day one.

​
How matching works

For standard symbols (letters and digits, 2 to 12 characters) matching is case-insensitive: disabling PEPE also blocks pepe, Pepe, and every other casing. The contract folds case before checking the registry, so there is no casing trick that slips past a disable.

​
What the registry cannot block

Symbols containing emoji, non-ASCII unicode, or lookalike characters cannot be protected. Disabling PEPE blocks pepe but not a homoglyph variant that swaps in a visually identical character from another alphabet. The registry protects the exact case-folded string for standard symbols and nothing more. Always verify a coin by its contract address, shown on its page and in Contracts, never by its ticker alone.

​
OG protection

A coin that sustains real traded value earns protection for its ticker:
  1. Trigger. When a coin’s trailing 48-hour median FDV stays at or above $200,000, the platform stages a disable of that ticker. The median is measured by the platform from on-chain prices; the measurement is platform-computed, and the staging transaction is on-chain and publicly evented.
  2. The 14-day window. Fourteen days after staging, anyone can send the activation transaction; activation is permissionless. The contract enforces the window: the program cannot skip it, and an early activation reverts.
  3. After activation. New launches with that ticker revert. Coins with the same ticker that launched before activation keep existing; a disable is forward-looking only and touches no deployed coin.
The contract owner holds two levers over this path, both publicly evented: it can veto a staged disable during the window, and it can act directly in an emergency. The window is contract-enforced against the platform; it is not unconditional against the owner. Anyone can watch the events on Blockscout to see exactly what was staged, vetoed, or activated, and when. Coins launched before the current program are OG-eligible too: a legacy coin whose 48-hour median FDV holds above $200,000 earns the same staged protection for its ticker. The site shows an OG tag on protected coins. The tag reflects the platform’s median measurement, and the underlying disable is verifiable on-chain.

​
Migrations

A migration disables its ticker immediately, in the same transaction that launches the migrated coin. There is no 14-day window on this path: the team has already evaluated the migration, and leaving the ticker open for two weeks would invite squatting on the exact name being migrated.

​
What this means when launching

  • Pick any standard symbol that is not on the registry; the launch reverts if it is.
  • A ticker you launch is not reserved for you by launching it. Protection comes only from the OG path (sustained $200k median FDV) or a migration.
  • Nothing about the registry changes the name and symbol sanitization rules, which still apply first.
