Is it possible to read the price of an asset on Tinyman from a stateful smart contract? Kind of like a on-chain oracle?

Yes, they’re storing information in local state of the pool contract, see python here for how its accessed.

tinymanorg/tinyman-py-sdk/blob/main/tinyman/v1/pools.py#L32-L51

    
      
          
          
asset1_id = get_state_int(validator_app_state, 'a1')
          asset2_id = get_state_int(validator_app_state, 'a2')
          
          
pool_logicsig = get_pool_logicsig(validator_app_id, asset1_id, asset2_id)
          pool_address = pool_logicsig.address()
          
          
assert(account_info['address'] == pool_address)
          
          
asset1_reserves = get_state_int(validator_app_state, 's1')
          asset2_reserves = get_state_int(validator_app_state, 's2')
          issued_liquidity = get_state_int(validator_app_state, 'ilt')
          unclaimed_protocol_fees = get_state_int(validator_app_state, 'p')
          
          
liquidity_asset = account_info['created-assets'][0]
          liquidity_asset_id = liquidity_asset['index']
          
          
outstanding_asset1_amount = get_state_int(validator_app_state, b64encode(b'o' + (asset1_id).to_bytes(8, 'big')))
          outstanding_asset2_amount = get_state_int(validator_app_state, b64encode(b'o' + (asset2_id).to_bytes(8, 'big')))
          outstanding_liquidity_asset_amount = get_state_int(validator_app_state, b64encode(b'o' + (liquidity_asset_id).to_bytes(8, 'big')))
