Caldera ERA
the rollup hatchery that knits a swarm of L2 chains into one web
🎭 a builder-elemental, half workshop and half web: it forges chains to order and threads them into a single shared network
💬 “Tell me what your app needs and I'll hatch you a fresh chain by this afternoon. Then I tie it to all the others, so your users never feel the seams between them.”
- Caldera is a Rollup-as-a-Service platform: it spins up custom layer-2 chains for builders in hours.
- Its Metalayer stitches those chains together so they can bridge liquidity and message each other.
- ERA is the token: it pays gas, it is staked to secure cross-chain validation, and it votes on governance.
- Supply is fixed at 1 billion ERA, with no way to mint more.
📖 The Story
March 2022. Two Stanford computer-science friends, Matt Katz and Parker Jou, started Caldera. They had built things at Nvidia, Apple, Waymo, and Skiff first, and they kept noticing the same problem: spinning up your own Ethereum layer-2 chain took months of plumbing that most teams did not want to touch.
So they turned that plumbing into a service. With Caldera, a team describes the chain it wants and gets a working rollup in hours. Underneath sit two pieces: the Rollup Engine, which creates and runs the chains, and the Metalayer, which wires the chains together so they can pass messages and share liquidity. A chain born inside Caldera is connected to its siblings from the moment it hatches.
Investors paid attention. In February 2023 Caldera raised a $9M seed round co-led by Sequoia and Dragonfly, and in July 2024 a $15M Series A led by Founders Fund. The work was infrastructure, the kind nobody sees, but a lot of people were betting on it.
On July 17, 2025 the ERA token went live alongside a community airdrop. It is the gas, staking, and governance token of the Metalayer, and its supply was fixed at one billion from day one.

🧩 How it works
Caldera is not its own blockchain. It is a workshop that sits on top of Ethereum. When a team needs a chain, the Rollup Engine deploys an app-specific rollup for them, and that rollup leans on Ethereum for its security. The Metalayer is the web that runs between all of those chains, routing messages and liquidity, and ERA staking is what keeps that cross-chain traffic honest.
🌗 Light & Shadow
- Turns months of chain-building work into a job that takes hours, which is a real, concrete pain it removes for builders
- The Metalayer is the rarer, harder half: most tools launch a chain, fewer also connect the chains so they share liquidity
- Fixed supply of 1 billion ERA with no inflation, so the count never quietly grows on holders
- Backed by serious investors (Sequoia and Dragonfly led the seed; Founders Fund led the Series A)
- It is a crowded field. Conduit, AltLayer, and Gelato chase the same Rollup-as-a-Service market, so it has to keep winning builders
- The token is young: ERA only launched in July 2025, so there is little long history to judge it by
- The price has been rough. ERA hit about $1.88 at its 2025 peak and traded near $0.10 in mid-2026, far below that high
- Most of the supply sits with early backers, the team, and the treasury, and unlocks over time, which can add selling pressure
🧬 Evolution lineage
Caldera is an independent project, not a fork of any coin. It belongs to the Ethereum layer-2 family as a rollup-infrastructure player. Its closest peers are other rollup-as-a-service builders rather than a coin it branched off from.

❓ FAQ
- What is Caldera?
- A platform that lets builders launch their own custom Ethereum layer-2 chain (a rollup) in hours instead of months. Its Metalayer then connects all those chains so they can share liquidity and pass messages to each other.
- What is the ERA token for?
- ERA does three jobs: it pays gas across the connected chains, it is staked to help secure cross-chain message validation on the Metalayer, and it is used to vote on governance decisions.
- How many ERA tokens are there?
- The supply is fixed at 1 billion ERA, and there is no mechanism to mint more. Max supply and total supply are the same number, so the cap never moves.
- Is Caldera its own blockchain?
- No. Caldera is infrastructure that sits on top of Ethereum, not a standalone chain with its own mining. The rollups it deploys inherit Ethereum's security, and the Metalayer uses staking to secure the messages that travel between them.
