## Publishing the contract
There are six constructor arguments.
There are five constructor arguments.
The first three, `name`, `symbol` and `decimals` have matching getter methods, are analogous to the ERC20 methods of the same name.
The `declaration` parameter is optional and can be any arbitrary content. Typically it defines a content hash of data describing the pool resource. A value of `bytes32(0x0)` means "no declaration defined."
The `tokenRegistry` parameter takes an address to a smart contract controlling which tokens are allowed in the pool. See "Token approval" below. A value of `address(0x0)` deactivates this control, and allows the pool to hold all tokens by default (although they may still be subject to value limits).
The `tokenLimiter` parameter takes an address to a smart contract controlling value limits of tokens in the pool. See "Token limits" below. A value of `address(0x0)` deactivates this control, and allows any value of (approved) tokens to be held by the pool.

By default, all deducted fees are credited to the pool contract.
Using the `setFeeAddress` method, an external beneficiary for the fees may be defined. That beneficiary will be eligible to receive all fees pending external payment _from that moment on_. Note that this does also include any fees that were not already claimed by a previous beneficiary.
Using the `setFeeAddress` method, an external beneficiary for the fees may be defined. That beneficiary will be eligible to receive all fees pending external payment _from that moment on_.
**Important!** Note that this does also include any fees that were not already claimed by a previous beneficiary.
#### Withdrawing fees
Fees to be paid externally are accounted for internally in the contract, and may be withdrawn at any time using either the `withdraw(outToken)` or `withdraw(outToken, value)` method. (Note the difference in method signature from the exchange method: `withdraw(outToken, inToken, value)`.
Fees to be paid externally are accounted for internally in the contract, and may be withdrawn at any time using either the `withdraw(outToken)` or `withdraw(outToken, value)` method.
## Sealing the contract
Note the difference between the fee withdrawal methods, and the method signature from the exchange method: `withdraw(outToken, inToken, value)`.
## Sealing contract properties
The contract implements the [CIC Seal](https://git.grassecon.net/cicnet/cic-contracts/#seal) interface for the following properties:
- Fee value
- Fee address
- Quoter contract address
Sealing allowed token lists and/or their respective value limits is the responsibility of the provider contracts themselves.
