EthereumETH

Programmable money and the base layer of on-chain finance.

The programmable settlement layer — the chain where DeFi, stablecoins and most of crypto actually lives.

What Ethereum is

Ethereum is the first general-purpose blockchain. Where Bitcoin processes payments, Ethereum runs arbitrary programs ("smart contracts") in a virtual machine (EVM) that every node on the network agrees on.

Almost every major crypto primitive lives on Ethereum or a chain that looks just like it:

  • Stablecoins (USDC, USDT) — most issuance is on Ethereum and its L2s
  • DEXes — Uniswap, Curve, Balancer
  • Lending — Aave, Compound, Morpho
  • Restaking / LSTs — Lido, EigenLayer
  • L2s — Arbitrum, Optimism, Base, zkSync — all settle on Ethereum

Why ETH is valuable

Three overlapping value streams:

  1. Gas currency — every transaction on L1 (and indirectly on L2s) pays in ETH.
  2. Productive collateral — ETH is the dominant collateral asset across DeFi (lending, LP positions, stablecoin backing).
  3. Yield asset — staked ETH earns a real protocol yield (~3–5%), with additional restaking yields on top.

After The Merge (2022) and EIP-1559, ETH has a variable but low issuance, with a burn mechanism. When network activity is high, more ETH is burned than issued → supply actually shrinks.

How to think about ETH

ETH sits between "sound money" and "tech stock" narratives. Its price tracks:

DriverEffect
BTC directionDominant beta — ETH follows BTC with amplification
L2 / DeFi activityDrives fee burn, net issuance, narrative
Staking yieldSets the floor yield for the whole crypto market
Stablecoin supplyTracks fiat demand for on-chain dollars (proxy for ETH demand)
TVLTotal USD locked in DeFi — the size of ETH's user base

Risks and trade-offs

  • Execution risk — Ethereum roadmap is complex (Danksharding, Verkle trees, PeerDAS). Delays happen.
  • L2 fragmentation — activity moving to L2s reduces L1 fee burn → can make ETH less deflationary.
  • Regulatory ambiguity — staking is under regulator scrutiny in some jurisdictions.
  • Smart contract risk — when you use ETH in DeFi, you take on the risk of the protocol on top.

What to watch on Exum

  • ETH/BTC pair — the single best signal for altcoin risk-on / risk-off
  • L2 fees vs L1 fees — rising L2 share = adoption, falling L1 burn
  • Staking ratio — % of total ETH supply staked
  • Gas price — demand for blockspace, directly translating into fee burn

Frequently asked

Does ETH have a supply cap?
No hard cap, but post-Merge issuance is ~0.5%/year and EIP-1559 burns a portion of every transaction fee. Under heavy usage, ETH can be net deflationary.
What is staking and should I do it?
Staking locks 32 ETH (or any amount via liquid staking) to help secure the network, in exchange for a protocol yield (~3–5%). See the [Staking](/learn/glossary/staking) article.
Why is ETH different from BTC?
BTC is money. ETH is money plus a global computer. ETH drives DeFi, NFTs, stablecoins and the L2 ecosystem — its value is tied to network usage, not only scarcity.
