Struct PoolMeta 

#[repr(C)]
pub struct PoolMeta {
    pub address: [u8; 32],
    pub pair_index: u16,
    pub fee_bps: u16,
    pub venue_id: u8,
    pub protocol_id: u8,
    pub _pad: [u8; 2],
}

Per-pool metadata: compact identity for a single DEX pool.

Fixed-size (40 bytes) to avoid heap allocations in WASM memory. Layout: address(32) + pair_index(2) + fee_bps(2) + venue_id(1) + protocol_id(1) + pad(2) = 40.

Fields

address: [u8; 32]

Pool contract address: 32 bytes (EVM uses first 20, Solana uses all 32).

pair_index: u16

Pair index for multi-asset pools (0 for standard 2-token pools).

fee_bps: u16

Pool fee in basis points.

venue_id: u8

Venue ID (VENUE_DEX_ARB, VENUE_DEX_SOL, etc.)

protocol_id: u8

Protocol: 0=unknown, 1=uniswap_v2, 2=uniswap_v3, 3=curve, 4=balancer_v2, 5=aerodrome, 6=velodrome, 7=camelot, 8=raydium_clmm, 9=orca_whirlpool

_pad: [u8; 2]

Padding to align to 8 bytes (40 is already 8-aligned, but keep for future).
