 Standard Balancer pools also implement the optional `Version` interface (for easy on- and off-chain verification of the contract version), and `IPoolInfo`, which exposes Vault getters (e.g., `getTokens`, and `getTokenInfo`) through the pool itself as a convenience. On top of that, the standard pools define custom interfaces that return structs corresponding to the immutable and dynamic data fields for the pools. For instance, Weighted Pools return the weights. Note that dynamic pool values (e.g., live balances), exposed through either `IPoolInfo` or the custom interfaces, will only be valid on-chain if the Vault is locked (i.e., not in the middle of a transaction).

 ::: info application context on computeBalance
 In the context of `computeBalance` the invariant is used as a measure of liquidity. What you need to consider when implementing all possible liquidity operations on the pool is that:
-- bptAmountOut for an unbalanced add liquidity operation should equal bptAmountOut for a proportional add liquidity in the case that `exactAmountsIn` for the unbalanced add are equal to the `amountsIn` for the same bptAmountOut for both addLiquidity scenarios. `AddLiquidityProportional` does not call into the custom pool it instead calculates BptAmountOut within the [BasePoolMath.sol](https://github.com/balancer/balancer-v3-monorepo/blob/main/pkg/vault/contracts/BasePoolMath.sol#L50-L71) whereas `addLiquidityUnbalanced` calls the custom pool's `computeInvariant`. 
+- bptAmountOut for an unbalanced add liquidity operation should equal bptAmountOut for a proportional add liquidity in the case that `exactAmountsIn` for the unbalanced add are equal to the `amountsIn` for the same bptAmountOut for both addLiquidity scenarios. `AddLiquidityProportional` does not call into the custom pool it instead calculates BptAmountOut using [BasePoolMath.sol](https://github.com/balancer/balancer-v3-monorepo/blob/main/pkg/solidity-utils/contracts/math/BasePoolMath.sol#L50-L54) whereas `addLiquidityUnbalanced` calls the custom pool's `computeInvariant`. 
 - the amountIn for an exactBptAmountOut in an `addLiquiditySingleTokenExactOut` should equal the amountIn for an unbalanced addLiquidity when the bptAmountOut is expected to be the same for both operations. `addLiquiditySingleTokenExactOut` uses `computeBalance` whereas `addLiquidityUnbalanced` uses `computeInvariant`.
 
 These are important consideration to ensure that LPs get the same share of the pool's liquidity when adding liquidity. In a Uniswap V2 Pair adding liquidity not in proportional amounts gets [penalized](https://github.com/Uniswap/v2-core/blob/master/contracts/UniswapV2Pair.sol#L123), which you can also implement in a custom pool, as long as you accurately handle the bullet points outlined above.
