Fantom Network
Introduction
Fantom is a fast, high-throughput open-source smart contract platform for digital assets and dApps.
Founded in 2018, Fantom is designed to overcome the limitations of previous-generation blockchain platforms. Fantom is permissionless, decentralized, and open-source while achieving fast finality (1-2 second transaction confirmation) and low fees ($0.00001). Furthermore, Fantom is EVM-compatible.
Fantom code is completely open source. Anyone can read it, check on the progress, comment on it, and contribute. Fantom integrates industry-leaders oracle providers Chainlink and Band Protocol for maximum flexibility to access price feeds.

Appendix
Fantom token
The Fantom token FTM
is the native token of Fantom. This is similar to Ether in Ethereum. To interact with the Fantom network, FTM tokens are required to pay gas fees. The Covalent API response returns gas_*
fields in fiat units.
Token mapping
Covalent maintains an on-chain real-time mapping of token addresses between Ethereum mainnet and the Fantom chain. These addresses are used to reverse-lookup prices on Fantom and also to return the right token logo urls.
Some example of mapped tokens:
Token | Ethereum mainnet | Fantom mainnet |
---|---|---|
USDT | 0xdac17f958d2ee523a2206206994597c13d831ec7 | 0x1ffbd1e3584f139ca42d77ef99ef99550ecf46a8 |
YFI | 0x0bc529c00C6401aEF6D220BE8C6Ea1667F6Ad93e | 0xc396b190f251d7f79c583fd06347a09781f085c9 |

Token prices
For tokens that have a mapping back to Ethereum mainnet, Covalent is able to return the mapped prices.
