TRON RPC Endpoints

Dwellir provides TRON RPC endpoints at https://api-tron-mainnet.n.dwellir.com/<your-api-key> for mainnet. TRON uses its own API format rather than standard JSON-RPC. Replace <your-api-key> with the key from your Dwellir dashboard.

Dwellir's TRON endpoints currently provide HTTPS access only. TRON uses HTTP and gRPC APIs with namespaces like /wallet, /walletsolidity, and /event. For real-time event monitoring, consider polling strategies or contact our team about dedicated node options.

Dwellir's TRON endpoints run full nodes that provide access to current state and recent transaction history. Full nodes can query account balances, execute transactions, and access TRC-20 token data. For deep historical queries using methods like getaccountbalance at arbitrary block heights, dedicated archive configurations may be required.

1. Sign up at dwellir.com and retrieve your API key from the dashboard. 2. Replace your current RPC URL (e.g., https://api.trongrid.io) with https://api-tron-mainnet.n.dwellir.com/<your-api-key>. The API supports TRON's HTTP API format including /wallet and /walletsolidity endpoints.

TRON mainnet uses TRX as the native token with ~3 second block times and 2,000+ TPS capacity. It uses Delegated Proof of Stake (DPoS) consensus with 27 Super Representatives. The TRON Virtual Machine (TVM) is EVM-compatible, enabling Solidity smart contract deployment. Block explorer: tronscan.org.

Dwellir's TRON endpoints support the official TronWeb SDK (JavaScript), Java-tron, and other TRON-specific libraries. While TVM is EVM-compatible for smart contracts, TRON's API differs from Ethereum JSON-RPC. Configure TronWeb's fullHost with the Dwellir RPC URL.

TRON uses two resources instead of gas: 1) Bandwidth is for basic transactions (TRX transfers, TRC-10 tokens)—you get 600 free points daily (~18 transfers), 2) Energy is for smart contracts (TRC-20 transfers like USDT)—no free quota, requires 32,000-130,000 units per USDT transfer. To reduce fees: Freeze TRX to earn Energy (~13.86 Energy per TRX frozen) or Bandwidth (~1.08 per TRX). Freezing 11,000+ TRX covers frequent USDT transfers. Alternatively, rent Energy from marketplaces like Tronsave for up to 80% savings vs burning TRX. Frozen TRX has a 14-day unlock period.

Use TRON's Stake 2.0 system via TronWeb: tronWeb.transactionBuilder.freezeBalanceV2(amount, resource, ownerAddress) where resource is 'ENERGY' or 'BANDWIDTH'. To unfreeze: tronWeb.transactionBuilder.unfreezeBalanceV2(amount, resource, ownerAddress) (requires 14-day wait after unfreezing). You can delegate resources to other addresses without transferring TRX ownership. Check your resources via /wallet/getaccountresource. Pro tip: For TRC-20 transfers to wallets that already hold the token, Energy cost is ~64,285 units; transfers to empty wallets cost ~130,000 units.
