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.
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.
what needs to be done to add a new contract:
1. add EVAL_CODE to eval.h
2. initialize the variables in the CCinit function below
3. write a Validate function to reject any unsanctioned usage of vin/vout
4. make helper functions to create rawtx for RPC functions
5. add rpc calls to rpcserver.cpp and rpcserver.h and in one of the rpc.cpp files
6. add the new .cpp files to src/Makefile.am
IMPORTANT: make sure that all CC inputs and CC outputs are properly accounted for and reconcile to the satoshi. The built in utxo management will enforce overall vin/vout constraints but it wont know anything about the CC constraints. That is what your Validate function needs to do.
Generally speaking, there will be normal coins that change into CC outputs, CC outputs that go back to being normal coins, CC outputs that are spent to new CC outputs.
Make sure both the CC coins and normal coins are preserved and follow the rules that make sense. It is a good idea to define specific roles for specific vins and vouts to reduce the complexity of validation.

/*
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>
swaps <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.

/*
The rewards CC contract is initially for OOT, which needs this functionality. However, many of the attributes can be parameterized to allow different rewards programs to run. Multiple rewards plans could even run on the same blockchain, though the user would need to choose which one to lock funds into.
At the high level, the user would lock funds for some amount of time and at the end of it, would get all the locked funds back with an additional reward. So there needs to be a lock funds and unlock funds ability. Additionally, the rewards need to come from somewhere, so similar to the faucet, there would be a way to fund the reward.
Additional requirements are for the user to be able to lock funds via SPV. This requirement in turns forces the creation of a way for anybody to be able to unlock the funds as that operation requires a native daemon running and cant be done over SPV. The idea is to allow anybody to run a script that would unlock all funds that are matured. As far as the user is concerned, he locks his funds via SPV and after some time it comes back with an extra reward.
In reality, the funds are locked into a CC address that is unspendable, except for some special conditions and it needs to come back to the address that funded the lock. In order to implement this, several things are clear.
1) each locked CC utxo needs to be linked to a specific rewards plan
2) each locked CC utxo needs to know the only address that it can be unlocked into
3) SPV requirement means the lock transaction needs to be able to be created without any CC signing
The opreturn will be used to store the name of the rewards plan and all funding and locked funds with the same plan will use the same pool of rewards. plan names will be limited to 8 chars and encoded into a uint64_t.
The initial funding transaction will have all the parameters for the rewards plan encoded in the vouts. Additional fundings will just increase the available CC utxo for the rewards.
Locks wont have any CC vins, but will send to the RewardsCCaddress, with the plan stringbits in the opreturn. vout1 will have the unlock address and no other destination is valid.
Unlock does a CC spend to the vout1 address
