CHAINFLIP enables cross-chain cryptocurrency swapping — for example, swapping Bitcoin with Ethereum — without using centralised exchanges, specialised wallets, or wrapped tokens. Chainflip functions similarly to UniSwap, but supports cross-chain transactions using liquidity pools.

Existing decentralised token swapping solutions suffer from a range of issues that severely limit usability, privacy, and practicality. CHAINFLIP is a protocol for automated cross-chain token swaps that resolves these issues. Fees to compensate both network and liquidity providers are included in each swap, removing the need to obtain native tokens to pay gas fees. The operations of the system are primarily executed by a network of staked vault nodes, which jointly manage and secure both the volume and diversity of liquidity required to facilitate token swaps. The network of vault nodes acts as the network’s decentralised authority, and achieves consensus over the state of the swaps, liquidity, and balances of the network using parameters outlined by a permissionless distributed database.

Ref Finance is a community-led, multi-purpose Decentralized Finance (DeFi) platform built on NEAR Protocol. Ref combines several core components: a decentralized exchange, lending, a synthetic asset issuer, and more -— into a single, synchronous DeFi stack.

Ref will take full advantage of NEAR’s low fees ($0.005 per swap), one-to-two second finality, and WebAssembly-based runtime (hello, Rust smart contracts!) to rival even CEX costs and speeds and become a powerful addition to the increasingly multi-chain DeFi ecosystem.

Using the recently launched Rainbow Bridge (NEAR <> ETH), traders can utilize the billions of dollars in ERC-20-compliant assets from Ethereum, and eventually, from any chain (BSC, Polygon/Matic, Cosmos/IBC, and others) on NEAR.

Ref Finance’s first product is an automated market maker (AMM). It is similar to Uniswap, with a few changes:

- Multiple pools in a single contract. Traders can trade across pools atomically in a single transaction.
- Customizable LP fees per pool. LPs can charge higher fees for illiquid or highly volatile tokens.
Referral fees for swaps, currently set at 1 bps. Developers can earn rewards for building UIs and other applications on top of Ref Finance.
- The Ref Finance community is planning to launch a DAO on NEAR (using Sputnik DAO) to facilitate future development, upgrades, and community building. The DAO’s treasury will receive 4 bps from each swap.

The DAO will be governed by the $REF token, which will be distributed to LPs, developers, and users of the platform. The distribution details and mechanisms will be described in subsequent posts.

Seaport is a new web3 marketplace protocol for safely and efficiently buying and selling NFTs. This protocol is not just for OpenSea – but for all builders, creators and collectors of NFTs. The core smart contract is open source and inherently decentralized, with no contract owner, upgradeability, or other special privileges. 

Most current NFT marketplaces only allow for listings where one party agrees to supply an NFT and the other agrees to supply a payment token. Seaport takes a different approach: offerers can agree to supply a number of ETH / ERC20 / ERC721 / ERC1155 items — this is the “offer.” In order for that offer to be accepted, a number of items must be received by the recipients indicated by the offerer — this is the “consideration.”

Every Seaport listing consists of the same basic structure, including an improved EIP-712 signature payload that clearly outlines what can be spent and what will be received back by whom. However, there are a number of different ways that the fulfiller can choose to have listings fulfilled.

The most straightforward fulfillment option involves choosing a specific listing and creating an implied “mirror” of that listing, where the fulfiller receives all offer items and supplies all consideration items. Seaport also supports the option to fulfill any number of listings at once through a set of “fulfillments” — each fulfillment corresponds to a single item transfer and indicates a group of offer items that the submitter can match with corresponding consideration items. As long as each consideration item on each listing is fully credited after all fulfillments have been applied, the offerers can leverage their coincidence of wants and complete their transfers. This enables elimination of redundant transfers (which are generally the most gas-intensive component of the protocol) and allows for novel and efficient transactions.

Offerers may also optionally elect to designate both a “zone” and a “conduit” on any listing. Anyone can create new zones or deploy new conduits. A zone is an account (usually a contract) that performs additional validation prior to fulfillment, and that can cancel the listing on behalf of the offerer.

A conduit is a contract where offerers set token approvals. The owner of the conduit can add and remove “channels” for the conduit, and registered channels can instruct the conduit on how to transfer tokens. These two concepts enable extensibility and upgradeability in a fully “opt-in” fashion, giving creators, collectors, and platforms additional ability to make their own choices regarding how they utilize Seaport while maintaining broad composability with other listings on the protocol.

Each item on a listing can also optionally specify that some “criteria” be met in place of requiring a specific tokenId, enabling collection-level and trait-level offers. Furthermore, each item can specify a distinct “start amount” and “end amount” which are then compared to the current time as well as the start and end time of the listing to derive a current amount — this enables ascending and descending amount mechanics such as reverse dutch auctions.

Additionally, any listing can also opt to support partial fills of offered items, where fulfillers can elect to spend some portion of each of the total offered items and receive back an equivalent portion of each consideration item as long as the relative ratios remain unchanged based on the initial offer. Offerers can combine partial fills with criteria-based items to create standing offers to buy or sell multiple NFTs that all share a given characteristic.

Finally, the Seaport protocol supports “tipping” — a fulfiller may include additional consideration items when fulfilling a listing as long as they do not “tip” more than the original offer. This allows alternative interfaces to include their own fees, and can be combined with zones to support listings with dynamic amounts and recipients, as well as other novel applications like on-chain english auctions.

NFTSwaps is a Cross-chain and Permissionless Platform for swapping NFT for better prices. Powered by Binance Smart Chain.

The history of NFTs has shown that a very small percentage of NFTs stay relevant over time, with most NFTs losing their value after a few months. NFTs quickly become illiquid and therefore holder can't sell.

Using NFTSwaps, any one can deposit their NFT to the NFTSwaps required pool and obtain BEP20 token derivatives that can be exchanged directly on PancakeSwap and BakerySwap from the NFTSwaps UI.
