Appendix
X Gas token
X token is the native token of the X network. This is similar to Ether in Ethereum. To interact with the X network, X tokens are required to pay as gas fees. Covalent’s responses automatically returns gas_*
fields in the MATIC units.
Token mapping
Covalent maintains an on-chain real-time mapping of token addresses between Ethereum mainnet and the X chain. These addresses are used to reverse-lookup prices on X and also to return the right token logo urls.
Some example of mapped tokens:
Token | Ethereum mainnet | X mainnet |
---|---|---|
USDT | 0xdac17f958d2ee523a2206206994597c13d831ec7 | 0xc2132d05d31c914a87c6611c10748aeb04b58e8f |
Uniswap UNI | 0x1f9840a85d5af5bf1d1762f925bdaddc4201f984 | 0xb33eaad8d922b1083446dc23f610c2567fb5180f |
Token prices
For tokens that have a mapping back to Ethereum mainnet, Covalent is able to return the mapped prices.
