Supported endpoints #
All Covalent Class A endpoints are supported for the TechPay mainnet and testnet. You can query the network via the unified API by changing thechainId
parameter
- Mainnet:
250
- Testnet:
4002
All requests to the Covalent API are done over HTTPS (calls over plain HTTP will fail.)
- api.covalenthq.com/v1/{chainId}/address/{address}/balances_v2/
Get token balances for address. Return a list of all ERC20 and NFT token balances including ERC721 and ERC1155 along with their current spot prices. - api.covalenthq.com/v1/{chainId}/address/{address}/transactions_v2/
Retrieve all transactions for address including their decoded log events. This endpoint does a deep-crawl of the blockchain to retrieve all kinds of transactions that references the address - api.covalenthq.com/v1/{chainId}/address/{address}/transfers_v2/
Get ERC20 token transfers for address along with historical token prices. - api.covalenthq.com/v1/{chainId}/tokens/{contract_address}/token_holders/
Return a paginated list of token holders contract_address as of any historical block height. - api.covalenthq.com/v1/{chainId}/events/address/{contract_address}/
Return a paginated list of decoded log events emitted by a particular smart contract. - api.covalenthq.com/v1/{chainId}/events/topics/{topic}/

Appendix #
TechPay token #
The TechPay token TPC
is the native token of TechPay. This is similar to Ether in Ethereum. To interact with the TechPay network, TPC 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 TechPay chain. These addresses are used to reverse-lookup prices on TechPay and also to return the right token logo urls.
Some example of mapped tokens:
Token | Ethereum mainnet | TechPay 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.
