TRON (TRX) On-Chain API

healthy 4,933 Subscribers

Live on-chain data from the TRON blockchain (TRX), the network that settles the largest share of the world's USDT (Tether) transfers, served straight from TRON's public TronGrid API — no key, nothing cached. The account endpoint returns any address's state: its TRX balance, when the account was created, and its holdings of the major TRC20 stablecoins and tokens (USDT, USDC, USDD and more) decoded to real amounts. The transfers endpoint returns the account's most recent TRC20 token transfers — the raw USDT flow that makes TRON the backbone of crypto payments — each with the counterparty, token, amount, direction and time. The transactions endpoint returns the account's recent system transactions with the type, result, block and time. The network endpoint returns the live state of the chain: the latest block, its timestamp, the producing super-representative and the block's transaction count. Everything is read live from TronGrid, nothing stored. This is the TRON on-chain layer for any wallet, explorer, payments, stablecoin or analytics app. Distinct from the XRP Ledger, Stellar, EVM and Solana on-chain APIs and from price feeds — this is TRON account state, TRC20/USDT transfers, transactions and block production. 4 endpoints, no key on our side.

Tron Super Representatives & Voting API

Tron's delegated-proof-of-stake governance — the Super Representative (SR) election — live from the public TronScan API, no key, nothing cached. Tron is run by 27 elected Super Representatives who produce the blocks, chosen by TRX holders who freeze TRX into votes; below them sit roughly 100 SR partners and candidates waiting to rotate in. The base Tron reader covers accounts and transactions, but not the SR election; this opens it. Rank the SRs and candidates by votes, each with its block production, missed blocks, produce rate and latest block. Look up a single SR by address for its votes, rank and production. And read a live election overview — the active 27, the candidate pool, the total frozen-TRX votes cast across all witnesses and the all-time blocks produced. The validator-and-voting layer for Tron wallets, staking dashboards, voters and analytics. Live from apilist.tronscanapi.com.

TRC-20 Token API

Read live data on TRON's TRC-20 tokens — the standard that settles the largest share of the world's USDT (Tether) — straight from the public TronScan API, no key. Resolve any TRC-20 contract to its name, symbol, decimals, total supply, holder count, on-chain verification status and live market data (USD price, market cap, 24-hour volume); stream a token's most recent transfers decoded into from / to / amount; and rank the whole TRC-20 universe by market cap, holders or volume. Where TRON wallet APIs show an account's activity, this is the token-level view — what a token is and how it moves. The TRC-20 data layer every wallet, explorer, trading tool and analytics dashboard needs. Live; short cache only.

Stablecoin Supply API

Live circulating supply, chain distribution and supply history for any stablecoin, keyless. For one stablecoin (USDT, USDC, DAI, USDe) get its total circulating supply, peg type and mechanism, price, 1d/7d/30d supply change and market dominance; the per-chain breakdown of where that supply actually lives; and the circulating-supply history over time, for the whole asset or a single chain. Search 370+ stablecoins to find an id. Live, nothing stored. The single-stablecoin supply layer for treasury, risk, research and dashboard apps — distinct from whole-ecosystem stablecoin feeds, this is one stablecoin in depth.

Stablecoin Chain Distribution API

Where dollar stablecoin liquidity actually lives, read live and keyless from each blockchain. USDC and USDT are issued natively on many chains, and the split between them is one of the most-watched signals in the layer-2 wars: Ethereum mainnet still holds the bulk, but Base, Arbitrum and the other rollups have been pulling stablecoin supply across as activity migrates. This API reads the native USDC and USDT supply directly from the token contract on each chain — Ethereum, Base, Arbitrum, Optimism, Polygon and Avalanche — not a single chain and not an aggregator, so you see the real on-chain distribution. The stablecoin endpoint takes a symbol (USDC or USDT) and returns its supply on every tracked chain, ranked, each with its share of that stablecoin and the Ethereum-versus-rollup split. The chains endpoint ranks the chains by their total native stablecoin liquidity (USDC and USDT together) — which chain hosts the most dollars. The summary endpoint is the top-down view: total USDC, total USDT, the combined total, the USDT-to-USDC ratio, and Ethereum's dominance versus the share that has moved to the rollups. Because USDC and USDT are dollar-pegged and read at the token's own on-chain decimals (read live from each contract, never assumed), the supply equals the dollars of stablecoin on that chain; only natively-issued supply is counted (bridged and peg tokens are excluded). This is the stablecoin chain-distribution cut — distinct from the single-chain token feeds, the generic stablecoin-supply aggregators and the price feeds: it is specifically the cross-chain liquidity map. Amounts are in US dollars. No key, nothing stored beyond a short cache.
