CCassetstx has the functions that create the EVAL_ASSETS transactions. It is expected that rpc calls would call these functions. For EVAL_ASSETS, the rpc functions are in rpcwallet.cpp
CCassetsCore has functions that are used in two contexts, both during rpc transaction create time and also during the blockchain validation. Using the identical functions is a good way to prevent them from being mismatched. The must match or the transaction will get rejected.

The SetAssetFillamounts() and ValidateAssetRemainder() work in tandem to calculate the vouts for a fill and to validate the vouts, respectively.
This pair of functions are critical to make sure the trading is correct and is the trickiest part of the assets contract.
//vin.0: normal input
//vin.1: unspendable.(vout.0 from buyoffer) buyTx.vout[0]
//vin.2+: valid CC output satisfies buyoffer (*tx.vin[2])->nValue
//vout.0: remaining amount of bid to unspendable
//vout.1: vin.1 value to signer of vin.2
//vout.2: vin.2 assetoshis to original pubkey
//vout.3: CC output for assetoshis change (if any)
//vout.4: normal output for change (if any)
//vout.n-1: opreturn [EVAL_ASSETS] ['B'] [assetid] [remaining asset required] [origpubkey]
ValidateAssetRemainder(remaining_price,tx.vout[0].nValue,nValue,tx.vout[1].nValue,tx.vout[2].nValue,totalunits);
Yes, this is quite confusing...
In ValudateAssetRemainder the naming convention is nValue is the coin/asset with the offer on the books and "units" is what it is being paid in. The high level check is to make sure we didnt lose any coins or assets, the harder to validate is the actual price paid as the "orderbook" is in terms of the combined nValue for the combined totalunits.
We assume that the effective unit cost in the orderbook is valid and that that amount was paid and also that any remainder will be close enough in effective unit cost to not matter. At the edge cases, this will probably be not true and maybe some orders wont be practically fillable when reduced to fractional state. However, the original pubkey that created the offer can always reclaim it.

CCcustom has most of the functions that need to be extended to create a new CC contract.
EVAL_CONTRACT is the naming convention and it should be added to cc/eval.h
bool Eval::Dispatch() in cc/eval.h needs to add the validation function in the switch
A CC scriptPubKey can only be spent if it is properly signed and validated. By constraining the vins and vouts, it is possible to implement a variety of functionality. CC vouts have an otherwise non-standard form, but it is properly supported by the enhanced bitcoin protocol code as a "cryptoconditions" output and the same pubkey will create a different address.
This allows creation of a special address(es) for each contract type, which has the privkey public. That allows anybody to properly sign and spend it, but with the constraints on what is allowed in the validation code, the contract functionality can be implemented.

#include "CCassets.h"
/*
Assets can be created or transferred.
native coins are also locked in the EVAL_ASSETS address, so we need a strict rule on when utxo in the special address are native coins and when they are assets. The specific rule that must not be violated is that vout0 for 'b'/'B' funcid are native coins. All other utxo locked in the special address are assets.
To create an asset use CC EVAL_ASSETS to create a transaction where vout[0] funds the assets. Externally each satoshi can be interpreted to represent 1 asset, or 100 million satoshis for one asset with 8 decimals, and the other decimals in between. The interpretation of the number of decimals is left to the higher level usages.
Once created, the assetid is the txid of the create transaction and using the assetid/0 it can spend the assets to however many outputs it creates. The restriction is that the last output must be an opreturn with the assetid. The sum of all but the first output needs to add up to the total assetoshis input. The first output is ignored and used for change from txfee.
What this means is that vout 0 of the creation txid and vouts 1 ... n-2 for transfer vouts are assetoshi outputs.
There is a special type of transfer to an unspendable address, that locks the asset and creates an offer for all. The details specified in the opreturn. In order to be compatible with the signing restrictions, the "unspendable" address is actually an address whose privkey is known to all. Funds sent to this address can only be spent if the swap parameters are fulfilled, or if the original pubkey cancels the offer by spending it.
Types of transactions:
create name:description -> txid for assetid
transfer <pubkey> <assetid> -> [{address:amount}, ... ] // like withdraw api
selloffer <pubkey> <txid/vout> <amount> -> cancel or fillsell -> mempool txid or rejected, might not confirm
buyoffer <amount> <assetid> <required> -> cancelbuy or fillbuy -> mempool txid or rejected, might not confirm
exchange <pubkey> <txid/vout> <required> <required assetid> -> cancel or fillexchange -> mempool txid or rejected, might not confirm
assetsaddress <pubkey> // all assets end up in a special address for each pubkey
assetbalance <pubkey> <assetid>
assetutxos <pubkey> <assetid>
assetsbalances <pubkey>
asks <assetid>
bids <assetid>

This file implements a simple CC faucet as an example of how to make a new CC contract. It wont have any fancy sybil protection but will serve the purpose of a fully automated faucet.
In order to implement a faucet, we need to have it funded. Once it is funded, anybody should be able to get some reasonable small amount.
This leads to needing to lock the funding in a CC protected output. And to put a spending limit. We can do a per transaction spending limit quite easily with vout constraints. However, that would allow anybody to issue thousands of transactions per block, so we also need to add a rate limiter.
To implement this, we can simply make any faucet vout fund the faucet. Then we can limit the number of confirmed utxo by combining faucet outputs and then only using utxo which are confirmed. This combined with a vout size limit will drastically limit the funds that can be withdrawn from the faucet.
