Assets Guide

Updated with changes in FIP#2
Asset Flow after FIP#2 Implementation


nNEO is the NEP-5 version of the NEO token. NEO is a UTXO asset on the Neo blockchain, with a minimum dividable unit of 1. In Flamingo, Assets must be dividable for calculation precision, and must be smart contract assets (NEP-5) to interact with smart contracts.

Users can convert between NEO and nNEO in Wrapper. The amount of input and output during wrapping and unwrapping has to be integers since the minimum unit of NEO is 1.


pONT is the NEP-5 version of the ONTd token after cross-chain. ONT is a native smart contract asset with a minimum dividable unit of 1. To facilitate calculation precision and smart contract interaction, users can convert ONT to OEP-4 based smart contract asset ONTd via Wing Finance. The Wrapper module in Flamingo can facilitate bi-directional cross-chain operation between ONTd on the Ontology Network and pONT on the Neo blockchain.

Assets on Flamincome

To maximize the fund utilization efficiency of our users, the team has designed Flamincome - a module on the Ethereum network that integrates yield aggregation with cross-chain value pegging. Flamincome users may either gain yield on Ethereum, or wrap their ERC-20 assets and use them on other blockchains, such as Neo.

The updated Flamincome has 2 asset types: x-asset and y-asset. Users can deposit original ERC-20 assets to mint either asset type.

Flamincome currently supports 3 types of original assets: USDT, WBTC , WETH.


x-assets for asset cross-chain

x-asset is an intermediate asset type for cross-chain functionalities, x-assets will not yield interest.

Users intending to use ERC-20 assets on Flamingo can perform bi-directional conversions between original ERC-20 assets and f-assets (see below graph for explanation) in Flamingo Wrapper. x-assets and px-assets will be generated as intermediate assets on Flamincome and Flamingo respectively, but are not visible to regular users.


y-assets for yield generation

Flamincome will tap on other DeFi protocols within the Ethereum DeFi ecosystem to optimize yield for the user under the premise of ensuring asset safety.

Users can deposit ERC-20 assets to y-asset. y-asset holders will enjoy the interest generated by the entire asset pool (underlining assets for both y-asset and x-asset).

The actual unit value of the y-asset is higher than that of the original asset as it comprises both the original asset and the yield, and its value will continue to rise.


Withdrawal Fee
Performance Fee
Withdrawal Fee

There is a withdrawal fee implemented for assets (both the principal and the yield) in order to ensure asset stability and prevent the impact of frequent fund transfers from eroding other users’ assets.

a. y-assets:0.5% b. x-assets: 0 for first 2 weeks after migration, then <=0.3%

Performance Fee

There is a 5% performance fee out of the yields of y-assets to cover GAS fees on the Ethereum network.

Assets on Flamingo


The Flamingo platform is evolving to support multiple cross-chain assets deriving from the same asset collateral. A NEP-5 based f-asset is thus introduced, and all pn-assets and px-assets along with other cross-chain assets to be introduced in the future can be exchanged to f-assets at a 1:1 ratio in Wrapper.

The asset cross-chain experience is fully packaged in Wrapper so that users can directly wrap their original assets from other blockchains to NEP-5 based f-assets. Common users will not need to deal with intermediate assets such as x-assets and px-assets.


px-assets will be generated as an intermediate product during the asset cross-chain process but will not be visible to regular users.

Legacy assets

Before the asset flow redesign, Flamincome users could deposit original ERC-20 assets to generate f-assets (ERC-20) to earn interest on Flamincome, and mint n-assets simultaneously by using f-assets (ERC-20) as a CDP and convert n-assets to NEP-5 based pn-assets in Wrapper, which can be used on Flamingo.

After the implementation of the asset flow redesign, f-assets(ERC-20), n-assets(ERC-20) and pn-assets(NEP-5) are now obsolete. Holders of these assets could migrate these assets to corresponding asset types by following instructions in the migration plan.
