# Smart contract interfaces
|
||||||
|
|
||||||
|
## Technology
|
||||||
|
|
||||||
|
CIC smart contracts are implemented using the *solidity* programming
|
||||||
|
language for the (Ethereum Virtual Machine (EVM).
|
||||||
|
|
||||||
|
## Adopted standards
|
||||||
|
|
||||||
|
### Signing
|
||||||
|
|
||||||
|
### ERC - Direct use
|
||||||
|
|
||||||
|
The following well-known solidity interfaces are used directly.
|
||||||
|
|
||||||
|
- [ERC20 - Token Standard](https://eips.ethereum.org/EIPS/eip-20)
|
||||||
|
|
||||||
|
- [ERC165 - Standard Interface
|
||||||
|
Detection](https://eips.ethereum.org/EIPS/eip-165)
|
||||||
|
|
||||||
|
- [ERC173 - Contract Ownership
|
||||||
|
Standard](https://eips.ethereum.org/EIPS/eip-173)
|
||||||
|
|
||||||
|
- [ERC191 - Signed Data
|
||||||
|
Standard](https://eips.ethereum.org/EIPS/eip-191)
|
||||||
|
|
||||||
|
- [ERC712 - Typed structured data hashing and
|
||||||
|
signing](https://eips.ethereum.org/EIPS/eip-712)
|
||||||
|
|
||||||
|
- [ERC721 - Non-Fungible Token
|
||||||
|
Standard](https://eips.ethereum.org/EIPS/eip-721)
|
||||||
|
|
||||||
|
- [ERC5007 - Time NFT (EIP-721 Time
|
||||||
|
Extension)](https://eips.ethereum.org/EIPS/eip-5007)
|
||||||
|
|
||||||
|
- [ERC5192 - Minimal Soulbound
|
||||||
|
NFTs](https://eips.ethereum.org/EIPS/eip-5192)
|
||||||
|
|
||||||
|
### ERCs Partial use
|
||||||
|
|
||||||
|
The following well-known solidity interfaces are partially implemented
|
||||||
|
in CIC native interfaces.
|
||||||
|
|
||||||
|
- [ERC5679 - Token Minting and
|
||||||
|
Burning](https://eips.ethereum.org/EIPS/eip-5679) (See `Minter`,
|
||||||
|
`Burner`)
|
||||||
|
|
||||||
|
## Native interfaces
|
||||||
|
|
||||||
|
### Accounts Index
|
||||||
|
|
||||||
|
Append-only list of addresses. Typically used for access control lists.
|
||||||
|
|
||||||
|
Addresses may be *added*, *removed*, aswell as *deactivated* and
|
||||||
|
*activated*. Deactivated accounts still count towards the `entryCount`.
|
||||||
|
|
||||||
|
The `entry` method is used to iterate the account list. The order of
|
||||||
|
which accounts are returned is not guaranteed. Any returned value
|
||||||
|
matching `address(0x00)` should be skipped, and not counted towards
|
||||||
|
`entryCount`.
|
||||||
|
|
||||||
|
May optionally record time when account was added.

### Accounts Index Mutable
|
||||||
|
|
||||||
|
Extends the functionality of `Accounts Index` to allow changes to the
|
||||||
|
address list.
|
||||||
|
|
||||||
|
Addresses may be *added*, *removed*, aswell as *deactivated* and
|
||||||
|
*activated*. Deactivated accounts still count towards the `entryCount`.

### Burner
|
||||||
|
|
||||||
|
Attached to `ERC20` and `ERC721` tokens that may be *burned*.
|
||||||
|
|
||||||
|
Implements the `burn(...)` part of `ERC5679` for interoperability.

### Chrono
|
||||||
|
|
||||||
|
Define a creation time for a resource.
|
||||||
|
|
||||||
|
Complements `ERC5007`.

|
||||||
|
|
||||||
|
### Declarator
|
||||||
|
|
||||||
|
Permissionless store of signed claims made by an address about other
|
||||||
|
addresses, or addresses about themselves.
|
||||||
|
|
||||||
|
It is used to declare or respond to certifications of vouchers, NFT,
|
||||||
|
voucher members.
|
||||||
|
|
||||||
|
Addresses may be Externally Owned Accounts or smart contracts.
|
||||||
|
|
||||||
|
Claims may be made with or without topics. A missing topic is synonymous
|
||||||
|
with a topic value of `bytes32(0x00)`.
|
||||||
|
|
||||||
|
Any number of claims can be made about an address under any number of
|
||||||
|
topics. All claims must be stored, and returned in the order which they
|
||||||
|
were added.

### Digest
|
||||||
|
|
||||||
|
Allows encoding of digests according to a specific encoding scheme.
|
||||||
|
|
||||||
|
Primary use-case is the abstraction of self-describing
|
||||||
|
[Multhash](https://multiformats.io/multihash/) encoding.
|
||||||
|
|
||||||
|
A default encoding *must* always be defined, and the encoding of a valid
|
||||||
|
digest *must* succeed with the default encoding.

### Expire
|
||||||
|
|
||||||
|
Defines an expiry time after which token balances or supply *cannot
|
||||||
|
change*.
|
||||||
|
|
||||||
|
A contract defining an expiry *must not* allow changing the expiration
|
||||||
|
time to a time in the past.

function expires() external returns (uint256);

|
// Return values must be:
|
||||||

|
||||||
|
|
||||||
|
### Faucet
|
||||||
|
|
||||||
|
Used for dispensing tokens to any address.
|
||||||
|
|
||||||
|
It can be used for gas tokens and *ERC20* alike.
|
||||||
|
|
||||||
|
The interface is the same whether the faucet is dispensing from existing
|
||||||
|
balance or minting new tokens.
|
||||||
|
|
||||||
|
The value dispersed *must* be the same for all addresses.
|
||||||
|
|
||||||
|
In general, four criteria are expected to exist in any combination for
|
||||||
|
limiting access to the faucet:
|
||||||
|
|
||||||
|
Time
|
||||||
|
A recipient may only use the faucet again after some time has passed.
|
||||||
|
|
||||||
|
Balance threshold
|
||||||
|
A recipient may only use the faucet after its balance is below a certain
|
||||||
|
amount.
|
||||||
|
|
||||||
|
Membership
|
||||||
|
A recipient may only use the faucet if it has been added to an access
|
||||||
|
control list.
|
||||||
|
|
||||||
|
Capacity
|
||||||
|
The contract has sufficient token funds to dispense the current defined
|
||||||
|
amount to dispense.
|
||||||
|
|
||||||
|
The *check(address)* contract call *must* evaluate all four criteria,
|
||||||
|
and *must* return `false` if any of the criteria are not met.

### Locator
|
||||||
|
|
||||||
|
This interface supports `ERC721 Metadata`, in particular the
|
||||||
|
`tokenURI(uint256)` call.
|
||||||
|
|
||||||
|
Off-chain resources in the CIC network *must* be defined in terms of
|
||||||
|
content addressed strings.
|
||||||
|
|
||||||
|
It *must* be possible to refer to all off-chain resources directly by
|
||||||
|
the content address.
|
||||||
|
|
||||||
|
Furthermore, it *should* be possible to refer to a resource by a
|
||||||
|
fully-qualified location on the web or an overlay network (e.g. tor).

#### Expressing locators in terms of numetic token id
|

Given the numeric token id `1234567890987654321` (`0x112210f4b16c1cb1`
|
||||||
|
hex), and a base url `https://contentgateway.grassecon.net`, the result
|
||||||
|
of the methods may be as follows:
|

#### Expressing locators in terms of a digest
|
||||||
|
|
||||||
|
Given the data `foo`, the digest algorithm `sha256` and a base url
|
||||||
|
`https://contentgateway.grassecon.net`, the result of the methods may be
|
||||||
|
as follows:
|
||||||
|
|
||||||
|
`toURI(sha256(foo))`
|
||||||
|
-\>
|
||||||
|
`"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`

|
||||||
|
|
||||||
|
#### Locator without URL
|
||||||
|
|
||||||
|
Given the data `foo`, the digest algorithm `sha256` and no base url, the
|
||||||
|
result of the methods may be as follows:
|
||||||
|
|
||||||
|
`toURI(sha256(foo))`
|
||||||
|
-\>
|
||||||
|
`"sha256:2c26b46b68ffc68ff99b453c1d30413413422d706483bfa0f98a5e886266e7ae"`
|
||||||
|
|
||||||
|
`toURL(sha256(foo))`
|

### Minter
|
||||||
|
|
||||||
|
Attached to `ERC20` and `ERC721` tokens that may be minted.
|
||||||
|
|
||||||
|
Implements the `mint(...)` and `safeMint(...)` parts of `ERC5679` for
|
||||||
|
interoperability.

### Msg
|
||||||
|
|
||||||
|
Enables a reference "message" to describe the contract using an
|
||||||
|
off-chain resource.
|
||||||
|
|
||||||
|
The reference may or may not be mutable.
|
||||||
|
|
||||||
|
The interface complements `Locator` and `MultiHash` to generate locators
|
||||||
|
for how to resolve the reference.

### Registry
|
||||||
|
|
||||||
|
The Registry interface is a key-value store resolving well-known
|
||||||
|
contract identifier names to contract addresses.
|
||||||
|
|
||||||
|
It currently has two distinct uses in the CIC context:
|
||||||
|
|
||||||
|
1. Entry-point to discover all relevant contracts of CIC networks.
|
||||||
|
|
||||||
|
2. Unique (ERC20) token symbol resolver.

### Seal
|
||||||
|
|
||||||
|
Some smart contract parameters may need to be mutable over part of a
|
||||||
|
smart contract’s lifetime.
|
||||||
|
|
||||||
|
This interface provides a method to explicitly signal when certain
|
||||||
|
parameters have been rendered immutable.
|
||||||
|
|
||||||
|
The value of `sealState()` *must not* decrease, and must not exceed
|
||||||
|
`maxSealState`.
|
||||||
|
|
||||||
|
`maxSealState` is used to define that *all mutable parameters* have been
|
||||||
|
rendered immutable. The practical implications of this will vary between
|
||||||
|
contracts.
|
||||||
|
|
||||||
|
The implementer is encouraged to use simple, descriptive names in the
|
||||||
|
source code to describe the applicable seal states.
|
||||||
|
|
||||||
|
Use cases of sealing include:
|
||||||
|
|
||||||
|
- Whether more tokens can be minted
|
||||||
|
|
||||||
|
- Allow ownership of a contract to be transferred
|
||||||
|
|
||||||
|
- The expiry time of a token (see `Expire`)

### TokenVend
|
||||||
|
|
||||||
|
This interface defines the mechanism for which a specific ERC20 token
|
||||||
|
may be exchanged for a different ERC20 token.
|
||||||
|
|
||||||
|
A typical use-case is generation of voting tokens based on a momentary
|
||||||
|
voucher balance. This is especially useful if the original ERC20 token
|
||||||
|
is subject to decay (demurrage).
|
||||||
|
|
||||||
|
The tokens used for exchange **SHOULD** be locked for the full duration
|
||||||
|
of holding the vended tokens.
|
||||||
|
|
||||||
|
The withdrawal function may or may not allow partial withdrawals.

||||||
|
function getFor(address _token) external returns (uint256);

### TokenVote
|
||||||
|
|
||||||
|
Execute elections with granular ERC20 token votes.
|
||||||
|
|
||||||
|
A proposal submitted for vote may or may not contain multiple options.
|
||||||
|
If multiple options are available, an ERC20 token holder may distribute
|
||||||
|
its vote among the options with the granularity of the token balance.
|
||||||
|
|
||||||
|
Voted tokens **SHOULD** be locked until the voting has finalized.
|
||||||
|
|
||||||
|
Finalization of voting should be callable by anyone.

### Writer
|
||||||
|
|
||||||
|
A complement to ERC173, which allows definition of a class of
|
||||||
|
super-users for a contract.
|
||||||
|
|
||||||
|
A super-user address may perform *more* actions than a "normal" address,
|
||||||
|
aswell as *some* actions normally limited to the *contract owner*.
|
||||||
|
|
||||||
|
If an *contract owner* is defined, No super-user should be able to
|
||||||
|
perform actions that *contract owner* cannot perform.
|
||||||
|
|
||||||
|
Typically, only the *contract owner*, if it is defined, can add or
|
||||||
|
remove a super-user.
|
||||||
|
|
||||||
|
Some use-case examples of super-user actions include:
|
||||||
|
|
||||||
|
- Mint new tokens.
|
||||||
|
|
||||||
|
- Change the amount dispensed by the faucet.
|
||||||
|
|
||||||
|
- Edit access control lists.
