USDT API

USDT (Tether) carries a large share of on-chain payments and trading across many blockchains. The queries below cover its price across networks, and its payments (transfers), trades, reserve and balances on Solana, with a live stream where one exists.

Most USDT volume lives on Tron: the Tron USDT API page covers tracing and streaming every TRC-20 transfer.

USDT Reserve API

Monitor the USDT reserve on Solana, or get its latest value, with the stream or query below.

🔗 Stream Example
🔗 API Example

subscription{
  Solana {
    TokenSupplyUpdates(
      where: {TokenSupplyUpdate: {Currency: {MintAddress: {is: "Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB"}}}}
    ) {
      TokenSupplyUpdate {
        Amount
        Currency {
          MintAddress
          Name
        }
        PreBalance
        PostBalance

      orderBy:{descending:Block_Time}
      where: {TokenSupplyUpdate: {Currency: {MintAddress: {is: "Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB"}}}}

      TokenSupplyUpdate {

          Name
        }
        PreBalance
        PostBalance
      }
    }
  }
}

USDT Balance API

Query the balance of one address, for compliance checks and analytics.

USDT Balance of an address

🔗 API Example

The query below returns the balance of 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM on Solana. It reads V2 BalanceUpdates, which keep about 8 hours of balance changes, so it returns nothing for an address whose balance has not changed in that time.

query MyQuery {
  Solana {
    BalanceUpdates(
      where: {BalanceUpdate: {Account: {Owner: {is: "9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM"}}, Currency: {MintAddress: {is: "Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB"}}}}
      orderBy: {descendingByField: "BalanceUpdate_Balance_maximum"}
    ) {
      BalanceUpdate {
        Balance: PostBalance(maximum: Block_Slot)
        Currency {
          Name
          Symbol
        }
      }
    }
  }
}

USDT Top Holders

Bitquery does not serve a complete list of the largest USDT holders on Solana, so this section has no query.

• V2 BalanceUpdates keeps about 8 hours of balance changes, so it misses every account that did not move in that time. On 9 October 2026 a top-100 query found 4 of the 10 largest token accounts. It missed the largest one, which held 852,550,053 USDT, 22% of the supply on Solana.
• V1 transfers have the full history, but a balance needs every transfer since the token was first minted on Solana. V1 refuses that query because its estimated run time is over the 2,000-second limit. On 7 October 2026 alone, 160,703 addresses received the token, so one day of history already needs at least 7 requests of 25,000 rows each.

Notes & Best Practices

• Prefer subscriptions (streams) for real-time detection (payments, trades).
• Use date ranges and pagination for historical analyses at scale.
• Join across entities (holders, transfers, trades) to build richer analytics.
• For multi-chain setups, run identical queries across networks and unify downstream.
• Tron and EVM are separate top-level selectors, so you can alias several in one request and compare a chain-by-chain breakdown without multiple round trips — see USDT across chains in one request.

Chain-specific USDT pages

• TRC20 USDT API (Tron) — Tron carries the largest share of USDT transfer activity: live transfers, whale holders, exchange deposit flows and mempool visibility.
