Hold.
Each swINTC is a pro-rata slice of the vault's liquidity in the pool. Its value is read from the pool account, not from an oracle.
How swINTC is valued
Value per swINTC = the vault's liquidity per swINTC × pool reserves ÷ pool liquidity.
In full:
(L_vault / supply) × (token_a_amount / 10^dec_a + token_b_amount / 10^dec_b) / pool.liquidity
One token of either issuer counts as one share of stock.
Where the growth comes from
Every conversion through the Meteora pool leaves a fee in its reserves, so each swINTC is backed by a little more stock. Compounding fees grow the reserves while the pool's liquidity stays the same. Single-token deposits through the vault's pool add a smaller second source: their 0.05% vault fee stays in the position without minting swINTC for it. See Fees.
