Access graph

A publicly available graph for Longtail is available. It includes documentation. https://testnet-graph.long.so.

Building

Longtail ("Seawater") is a diamond-like contract, with the frontend to access the Stylus diamond facets implemented in Solidity. So, Stylus is needed with Rust for the implementation contracts, and Foundry is needed to compile the contract.

To save on contract size, and to reduce gas overhead, this contract stores the addresses of the swap router, and the admin address, at compile-time.

So these variables must set at compile-time, like so:

Build variables

NameDescription
FLU_SEAWATER_PERMIT2_ADDRUniswap Permit2 router
FLU_SEAWATER_FUSDC_ADDRUSDC Super Asset to route every trade through

Build dependencies

NameSource
Rust (nightly version)Installer
Cargo Stylus subcommandRepo
FoundryInstaller
Makebuild-essentials if you're on Linux

Build process

make build

Testing

Testing is done with via a hosted test using cargo features with the testing flag. tests.sh is provided to run both test suites.

End to end testing is currently unavailable due to issues with the deployment toolchain.

Testing process

./tests.sh

Cargo test tracing

Some of the cargo tests have optional logging, which might help with debugging. To see these logs, enable the testing-dbg-<test> feature and run the tests without capturing stdout, ie cargo test --features=testing,testing-dbg-erc20 -- --nocapture.

Testing tools are available with the with_storage macro, which lets you set slots and maximum balances for ERC20 transfers. Reproducing on-chain transactions is possible by using a tracer on the chain the transaciton took place, then examining the storage slots that were accessed (perhaps by looking at SLOADs), and setting it explicitly with the macro.

Deployment

You can deploy the contracts using the deploy.sh script.

Test deployments

Deployments on a local node can be done with ./test-deploy.sh for simplicity.

Deployment variables

NameDescription
SEAWATER_PROXY_ADMINAddress that's permitted to administrate the code, including deploying updates, and creating pools.
STYLUS_ENDPOINTURL to access the Stylus node.
STYLUS_PRIVATE_KEYPrivate key to use for deployment.
FLU_SEAWATER_FUSDC_ADDRSuper USDC address to use as the base asset for each pool.

Leo

Leo (also known as the Seawater Rewards Manager) is a contract that allows users to vest their LP tokens in the form of a transferFrom using the NFTManager contract. Leo remembers who owns the LP NFTs it has, and does things like collect fees on the behalf of the owner, and knows to do so when determining "real yield" mixed with fees earned for LPing.

Functions

balanceOf

Count all NFTs assigned to an owner

NFTs assigned to the zero address are considered invalid, and this function throws for queries about the zero address.

function balanceOf(address _owner) external view returns (uint256);

Parameters

NameTypeDescription
_owneraddressAn address for whom to query the balance

Returns

NameTypeDescription
<none>uint256The number of NFTs owned by _owner, possibly zero

ownerOf

Find the owner of an NFT

NFTs assigned to zero address are considered invalid, and queries about them do throw.

function ownerOf(uint256 _tokenId) external view returns (address);

Parameters

NameTypeDescription
_tokenIduint256The identifier for an NFT

Returns

NameTypeDescription
<none>addressThe address of the owner of the NFT

safeTransferFrom

Transfers the ownership of an NFT from one address to another address

Throws unless msg.sender is the current owner, an authorized operator, or the approved address for this NFT. Throws if _from is not the current owner. Throws if _to is the zero address. Throws if _tokenId is not a valid NFT. When transfer is complete, this function checks if _to is a smart contract (code size > 0). If so, it calls onERC721Received on _to and throws if the return value is not bytes4(keccak256("onERC721Received(address,address,uint256,bytes)")).

function safeTransferFrom(address _from, address _to, uint256 _tokenId, bytes calldata data) external payable;

Parameters

NameTypeDescription
_fromaddressThe current owner of the NFT
_toaddressThe new owner
_tokenIduint256The NFT to transfer
databytesAdditional data with no specified format, sent in call to _to

safeTransferFrom

function safeTransferFrom(address _from, address _to, uint256 _tokenId) external payable;

Parameters

NameTypeDescription
_fromaddressThe current owner of the NFT
_toaddressThe new owner
_tokenIduint256The NFT to transfer

transferFrom

Transfer ownership of an NFT -- THE CALLER IS RESPONSIBLE TO CONFIRM THAT _to IS CAPABLE OF RECEIVING NFTS OR ELSE THEY MAY BE PERMANENTLY LOST

Throws unless msg.sender is the current owner, an authorized operator, or the approved address for this NFT. Throws if _from is not the current owner. Throws if _to is the zero address. Throws if _tokenId is not a valid NFT.

function transferFrom(address _from, address _to, uint256 _tokenId) external payable;

Parameters

NameTypeDescription
_fromaddressThe current owner of the NFT
_toaddressThe new owner
_tokenIduint256The NFT to transfer

approve

Change or reaffirm the approved address for an NFT

The zero address indicates there is no approved address. Throws unless msg.sender is the current NFT owner, or an authorized operator of the current owner.

function approve(address _approved, uint256 _tokenId) external payable;

Parameters

NameTypeDescription
_approvedaddressThe new approved NFT controller
_tokenIduint256The NFT to approve

setApprovalForAll

Enable or disable approval for a third party ("operator") to manage all of msg.sender's assets

Emits the ApprovalForAll event. The contract MUST allow multiple operators per owner.

function setApprovalForAll(address _operator, bool _approved) external;

Parameters

NameTypeDescription
_operatoraddressAddress to add to the set of authorized operators
_approvedboolTrue if the operator is approved, false to revoke approval

getApproved

Throws if _tokenId is not a valid NFT.

function getApproved(uint256 _tokenId) external view returns (address);

Parameters

NameTypeDescription
_tokenIduint256The NFT to find the approved address for

Returns

NameTypeDescription
<none>addressThe approved address for this NFT, or the zero address if there is none

isApprovedForAll

Query if an address is an authorized operator for another address

function isApprovedForAll(address _owner, address _operator) external view returns (bool);

NameTypeDescription
_owneraddressThe address that owns the NFTs
_operatoraddressThe address that acts on behalf of the owner

Returns

NameTypeDescription

function name() external view returns (string memory);

symbol

An abbreviated name for NFTs in this contract

function symbol() external view returns (string memory);

tokenURI

A distinct Uniform Resource Identifier (URI) for a given asset.

Throws if _tokenId is not a valid NFT. URIs are defined in RFC 3986. The URI may point to a JSON file that conforms to the "ERC721 Metadata JSON Schema".

function tokenURI(uint256) external view returns (string memory);

Events

Transfer

This emits when ownership of any NFT changes by any mechanism. This event emits when NFTs are created (from == 0) and destroyed (to == 0). Exception: during contract creation, any number of NFTs may be created and assigned without emitting Transfer. At the time of any transfer, the approved address for that NFT (if any) is reset to none.

event Transfer(address indexed _from, address indexed _to, uint256 indexed _tokenId);

Approval

This emits when the approved address for an NFT is changed or reaffirmed. The zero address indicates there is no approved address. When a Transfer event emits, this also indicates that the approved address for that NFT (if any) is reset to none.

event Approval(address indexed _owner, address indexed _approved, uint256 indexed _tokenId);

ApprovalForAll

This emits when an operator is enabled or disabled for an owner. The operator can manage all NFTs of the owner.

event ApprovalForAll(address indexed _owner, address indexed _operator, bool _approved);
