# On-Chain Programs

Tessera's token and referral infrastructure is deployed on Solana mainnet. All program addresses and token mints listed below can be independently verified using any Solana block explorer.

### Authorities & Security

The upgrade, mint, transfer fee config, and referral config authorities are held by a Fireblocks institutional custody wallet (`EXvTtxurWBUNNCtLojaN8ZBJFNJPZFSH3szoih9hh7YW`). The freeze authority on each token mint is held by a separate Fireblocks wallet (`7n2PNcDXVDMK2m8dyV9cVPNY7p4jM4ZMHv7TzfibEt8o`).

The Token Program upgrade authority was previously held by a Squads multisig (`HimRFy5qQHKribjfnqSDYLhZ6hujsmJgYoGRKir1NMrA`) and was transferred to the Fireblocks wallet on January 28, 2026. The Referral Program was deployed on February 7, 2026, and its upgrade authority was set to the Fireblocks wallet the same day.

| Authority                     | Scope                           | Description                                                                           |
| ----------------------------- | ------------------------------- | ------------------------------------------------------------------------------------- |
| Upgrade Authority             | Token Program, Referral Program | Can deploy program upgrades                                                           |
| Mint Authority                | Each token mint                 | Can mint tokens                                                                       |
| Transfer Fee Config Authority | Each token mint                 | Can update transfer fee rates                                                         |
| Freeze Authority              | Each token mint                 | Can freeze and thaw token accounts                                                    |
| Config Authority              | Referral Program                | Can update referral level splits, manage admins, and update fee recipient             |
| Default Fee Recipient         | Referral Program                | Receives Tessera Treasury's share of transfer fees, including any missing-level share |

Fee withdrawals from collected transfer fees are managed through a program-derived authority (PDA) within the Token Program's fee manager, so withdrawals follow the program's on-chain rules without direct wallet access.

Both programs were audited by Accretion Labs (report completed January 2026) and have been upgraded since. See [Security & Audits](/technicals/security-audits.md).
