Get Market Cap of a Four Meme Token
To get the market cap of a token we need two things, the latest PriceInUSD and total supply of the token. This query helps with getting the latest USD price of a token.
query MyQuery($currency: String) {
EVM(network: bsc) {
DEXTradeByTokens(
where: {Trade: {Currency: {SmartContract: {is: $currency}}}}
orderBy: {descending: Block_Time}
limit: {count:1}
){
Trade{
PriceInUSD
}
}
}
}
{
"currency": "0x9b48a54bcce09e59b0479060e9328ab7dbdb0d40"
}
Also, this query returns the total supply of a token.
query MyQuery($currency: String) {
EVM(network: bsc, dataset: combined) {
Transfers(
where: {Transfer: {Currency: {SmartContract: {is: $currency}}, Success: true}}
) {
minted: sum(of: Transfer_Amount, if: {Transfer: {Sender: {is: "0x0000000000000000000000000000000000000000"}}})
burned: sum(
of: Transfer_Amount
if: {Transfer: {Receiver: {is: "0x0000000000000000000000000000000000000000"}}}
)
}
}
}
{
"currency": "0x9b48a54bcce09e59b0479060e9328ab7dbdb0d40"
}
Now, to get market cap we need to multiply the total supply and price, that is:
Market Cap = Total Supply * PriceInUSD
