Simulator Stage • 1. Room Initialization

The administrator invokes initialize_raffle_room specifying a winner prize target (e.g., 10.00 SOL or USDC equivalent for RWA / BTC rooms). The program configures the platform fee on top, setting the total vault collection target (e.g., 14.00 SOL). The unique Room Vault PDA is derived as an isolated escrow for this room.

Deep Technical Protocol Specifications

Understand the exact on-chain mathematical structures, validation rules, and escrow designs behind TicketFi.

ROOM STATE

Event Room PDA

Each event chamber is a Program Derived Address (PDA) holding the room configuration, status details, pricing, and ticket sales logs.

Seeds Derivation
["room", room_id.to_le_bytes()]
  • Saves current tickets count on-chain.
  • Ensures isolation of room indices.
  • Calculates the vault PDA authority.
SECURE LOCK

Escrow Vault PDA

A unique system account containing the SOL deposited during ticket purchases. The smart contract has sole authority to claim or distribute funds.

Seeds Derivation
["vault", raffle_room_key.as_ref()]
  • Completely isolates room escrow funds.
  • Never stores funds in a shared admin account.
  • Only unlocked atomically on `settle_draw`.
ENTRY LEAF

Ticket PDA

Each ticket purchased creates a deterministic account holding the user's key. This represents a literal ticket leaf in the room's draw pool.

Seeds Derivation
["ticket", room_key.as_ref(), ticket_index.to_le_bytes()]
  • Registers buyer public key & timestamp.
  • Validated on-chain during settle verification.
  • Index matches Switchboard raw random index.
