Fraxtal Network API

healthy 4,230 Subscribers

Live on-chain data for Fraxtal (chain-id 252), an Optimistic-rollup EVM Layer 2 from Frax Finance that uses frxETH (Frax Ether) as its 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 frxETH balance (in wei and whole frxETH) 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 the Frax Finance protocol pools/yields feed and from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Fraxtal chain itself.

Frax Finance Pools & Yield API

Live liquidity-pool and yield data for the Frax Finance ecosystem — the FRAX stablecoin, frxETH and FXS — from the public Frax API, no key, nothing stored. This is the Frax-yield view: every incentivised Frax liquidity pool across every chain and DEX, with its locked liquidity and APY, distinct from the generic DeFi-yield and protocol APIs in the catalogue. The pools endpoint lists Frax pools — optionally filtered by chain or DEX platform — with the trading pair, the pool tokens, the value locked and the base and maximum APY. The pool endpoint returns one pool in full, including the reward breakdown across swap fees and incentive rewards. The summary endpoint aggregates the ecosystem: total value locked, the pool count and the distribution across chains and DEX platforms, plus the highest-yielding pools. Build DeFi yield dashboards, Frax-farming optimisers, APY trackers and treasury tools on top of real Frax Finance data. Filter by chain (ethereum, arbitrum, fraxtal, optimism, polygon and more) or platform (uniswap_v3, curve, convex, balancer); pool APYs are returned as percentages.

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.

Kaia API

Live EVM on-chain data for Kaia (chain id 8217) — the public Layer-1 formed by the merger of Klaytn and Finschia, whose native token is KAIA — served directly from public 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.
