Mantle Network API

healthy 3,406 Subscribers

Live on-chain data for Mantle (chain-id 5000), a modular EVM Layer 2 with the MNT native gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its MNT balance (in wei and whole MNT) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Mantle network specifically.

Bahamut API

Live EVM on-chain data for Bahamut (chain id 5165) — the Proof-of-Stake-and-Activity Layer-1 by Fastex, whose native token is FTN — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the FTN balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole FTN with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Bahamut and Fastex ecosystem. Live keyless upstream. 5 endpoints.

Towns API

Live EVM on-chain data for Towns (chain id 550) — an OP-Stack Layer-2 that powers decentralised group chat and on-chain social spaces, with gas paid in ETH — served directly from the public Towns JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Towns social ecosystem. Live keyless upstream. 5 endpoints.
