Supported endpoints¶
All Class A endpoints are supported for the Matic mainnet and the Amoy testnet. You can query either network via the unified API by changing the chainName.
Endpoints
A full list of all the requests you are able to do on the Polygon network using Covalent are available on the Covalent API documentation.
Appendix¶
MATIC gas token¶
To interact with Polygon network, MATIC tokens are required to pay gas fees. Covalent’s responses automatically return gas_* fields in MATIC units.
Token mapping¶
Covalent maintains an on-chain real-time mapping of token addresses between the Ethereum mainnet and Polygon. These addresses are used to reverse-lookup prices on MATIC and also to return the right token logo URLs.
Some example of mapped tokens:
| Token | Ethereum mainnet | Matic 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.
