Liquid Restaking Tokens Comparison API

healthy 4,056 Subscribers

The major Ethereum liquid-restaking tokens (LRTs) compared side by side, read keyless directly from the Ethereum blockchain via a public RPC node. Restaking is the DeFi narrative EigenLayer kicked off: you stake ETH and then restake it to also secure other services, earning Ethereum staking rewards PLUS restaking rewards on top. A liquid-restaking token — weETH (ether.fi), ezETH (Renzo), pufETH (Puffer) or rswETH (Swell) — is the liquid receipt for that position, and its on-chain exchange rate against ETH climbs as those combined rewards accrue. Restaking is a distinct, fast-moving asset class from plain liquid staking, and the spread between these tokens' rates and yields is what someone choosing a restaking provider (or arbitraging between LRTs) needs in one place. The rates endpoint is the comparison table: every tracked LRT with its live ETH exchange rate, its net APR over the last 30 days, its token supply and its issuer, ranked by yield. The token endpoint drills into one LRT by symbol — its rate, supply, ETH backing (TVL) and the APR over the last day, week and month. The convert endpoint converts any amount between any LRT and ETH, or between two LRTs, at the current on-chain rates. This is the liquid-RESTAKING comparison cut — distinct from liquid-STAKING tokens (the lstcompare feed), the single-protocol feeds (ether.fi, lido) and the DeFi-TVL feeds. Each token rate comes from its own on-chain rate source (a getRate() call, a rate-provider, or an ERC-4626 vault, depending on the protocol). APR is derived from real historical on-chain state; the 30-day window is used because several LRT rates update on an oracle schedule or in discrete ERC-4626 steps, making shorter windows noisy. The rate reflects realised value accrual — many LRTs additionally distribute points/airdrops that are NOT captured by the exchange rate. Rates are ETH per token. Keyless, nothing stored beyond a short cache.

ether.fi Liquid Restaking API

Live data for ether.fi, the largest liquid-restaking protocol on Ethereum, read keyless from ether.fi's public APR feed and directly from the Ethereum blockchain. Stake ETH with ether.fi and you get eETH, a rebasing token worth one ETH that earns both Ethereum staking rewards and EigenLayer restaking rewards on top — the "restaking premium" that made liquid restaking the fastest-growing corner of DeFi. weETH is the wrapped, value-accruing version of eETH that most of DeFi actually holds and lends against, and its eETH exchange rate is the number you need to value it. The apr endpoint returns the eETH restaking APR — the latest reading plus the recent daily history and its average. The restaked endpoint reads the chain directly: the total ETH restaked through ether.fi (the eETH supply, which rebases to track ETH one-for-one) and its US-dollar value, plus how much of it is wrapped into weETH versus held as eETH. The weeth endpoint is the wrapped-token view: the weETH supply and its on-chain rate — how much eETH (and therefore ETH and USD) one weETH is worth right now, the figure lending markets use to price weETH collateral. This is the ether.fi liquid-restaking cut — distinct from the synthetic-dollar protocol feed, the generic staking and yield-aggregator feeds and the generic token-info feed: it is the single-protocol view of the biggest restaking token, its yield, its size and its wrapped-token rate. APR is an annualised percentage; amounts are in ETH and USD; the rate is eETH per weETH (above 1.0, rising as yield accrues). No key, nothing stored beyond a short cache.

Karak Chain API

Live on-chain data for Karak mainnet (the universal restaking Ethereum L2, native ETH) via Blockscout — no key. Read network stats (block height, total transactions, gas), a gas oracle in gwei, the most recent blocks and full block detail by height or hash, any address balance and contract info, full transaction detail, ERC-20 token detail by contract, and a universal search across addresses, tokens, blocks and transactions. Real Layer-2 chain data with the rotating proxy as automatic fallback — 9 endpoints. Ideal for wallets, explorers, restaking dashboards, portfolio trackers and on-chain monitoring on Karak.

Swellchain API

Live Swellchain on-chain data via Blockscout. Swellchain is a restaking-powered Ethereum L2; gas and balances are in ETH. Network stats, gas prices, latest blocks, a block by height or hash, address detail with ETH balance, a transaction by hash, ERC-20 token metadata and a universal search across addresses, tokens, blocks and transactions. Real data, no key.

Honeypot Token Safety API

Live EVM token-safety checks — does this token let you sell, and what will it cost you? A "honeypot" is a token you can buy but cannot sell: the contract blocks the sell, traps your money or charges a punishing tax. This API detects it the only reliable way — by actually simulating a buy and a sell of the token against its real liquidity pool on-chain, right now (powered by honeypot.is), and reporting whether the sell went through, the live buy/sell/transfer tax, the gas cost and a plain risk summary. Beyond the honeypot verdict it returns the token's DEX trading pairs with their on-chain reserves and USD liquidity, the largest holders with the top-10 supply concentration (a top-heavy token can be dumped on you), and whether the contract source is verified/open and makes proxy calls. Covers Ethereum, BNB Chain, Base and other EVM chains. This is the EVM token-safety cut via live buy/sell simulation — distinct from the Solana rug-risk feed, which inspects SPL mint authorities on a different chain with a different method. A safety signal, not financial advice — always verify before trading.
