BNB Chain Uniswap v4 API: Stablecoin Pools, Swaps, Traders and Reserves
On BNB Chain, Uniswap v4 is above all a stablecoin venue: the USDT/USDC pools inside its PoolManager, 0x28e2ea090877bf75740558f6bfb36a5ffee9e9df, turn over tens of millions of dollars a day, while meme launches route a long tail of smaller pools through the same contract. Because v4 keeps every pool inside the PoolManager, pools are told apart by PoolId, a hash of the two tokens, the fee, the tick spacing and the hook, and on swap rows the buyer and seller fields both show the PoolManager, so the trader is Transaction.From. PancakeSwap Infinity uses the same singleton design on BNB Chain and has its own page. Every example runs in the IDE on a free account; the worked token is USDT, 0x55d398326f99059ff775485246999027b3197955, and the worked pool is the busiest USDT/USDC pool, PoolId 0x628ea54a6450645d2bb7b2911c8c6f3d7f3944c2f4703c259a1b85bf5569870b.
Which v4 pools trade USDT
Start here to get a PoolId. Grouping DEXTradeByTokens by PoolId with USDT in Currency lists every v4 pool of the token, its counter token, and the trades and USD volume in the window. Saved query here.

Trade: {
Dex: { ProtocolName: { is: "uniswap_v4" } }

Live swaps across every v4 pool on BNB Chain
The protocol filter as a subscription. On BNB Chain this stream is busy, so filter on PoolId or on a token when you only need part of it. Saved stream here.

Top traders of the pool
The PoolManager settles both sides of every v4 swap, so Trade.Buyer and Trade.Seller on DEXTrades are the PoolManager; rank accounts by Transaction.From instead. bought sums the token the trader received and sold the token it paid; Side.Type describes the counter-side, which is why the conditions look swapped. Saved query here; the top sellers query is the same sorted on sold.
{
EVM(network: bsc) {
DEXTradeByTokens(
where: {
Trade: {
PoolId: { is: "0x628ea54a6450645d2bb7b2911c8c6f3d7f3944c2f4703c259a1b85bf5569870b" }

}
}
Reserves of the pool
DEXPoolEvents rows carry the reserves the PoolManager holds for the pool after each change, in token units and USD. For v4 they are rebuilt from the concentrated positions around the current price. Filter on PoolId, or keep only the protocol name to stream every v4 pool. Saved queries by pool and all pools.

EVM(network: bsc) {
DEXPoolEvents(

PoolEvent: {
Pool: {
PoolId: { is: "0x628ea54a6450645d2bb7b2911c8c6f3d7f3944c2f4703c259a1b85bf5569870b" }

Frequently Asked Questions
What is the Uniswap v4 PoolManager address on BNB Chain?
0x28e2ea090877bf75740558f6bfb36a5ffee9e9df. All v4 pools on BNB Chain live inside it; Trade.PoolId tells them apart.
How do I get the PoolId of a Uniswap v4 pool on BSC?
Group DEXTradeByTokens by Trade.PoolId with one of the tokens in Currency and ProtocolName uniswap_v4. The rows list each pool of that token with its counter token and volume.
Why does every v4 swap show the PoolManager as buyer and seller?
The PoolManager settles both sides. Use Transaction.From for the account that sent the swap, or DEXTradeByTokens, whose Buyer and Seller are trader-aware.
Is PancakeSwap Infinity the same as Uniswap v4?
Same singleton design, separate protocol. Filter ProtocolName pancakeswap_infinity for it; its manager on BNB Chain is a different contract with its own PoolIds.
How far back does Uniswap v4 data go on BNB Chain?
DEXTrades and DEXTradeByTokens reach history on the archive and combined datasets. DEXPoolEvents is realtime-only, so record the reserve stream if you need it later.
