About Ethwei

“A boring and simple blockchain is a good blockchain.”

Ethwei is a Proof-of-Stake blockchain built on one conviction: the most trustworthy money just works — predictable, secure, free of unnecessary complexity. Like Bitcoin, but you can stake it.

7B ETE Genesis supply
10B ETE Hard cap
100M ETE / yr, 30 yrs Emission
0% Community tax

Simple by design

No bridges, no inter-chain messaging, minimal module surface. NFT, group, authz, feegrant, and mint modules removed to keep the attack surface small.

Fixed, honest supply

7B ETE genesis, 10B ETE hard cap — enforced in code against actual on-chain supply, so it cannot be exceeded. Fixed 100M ETE/year emission for 30 years, entirely to stakers, 0% community tax.

Secure

Built on battle-tested Cosmos SDK with stock, unmodified governance. The custom emission engine has passed two AI review passes that fixed real high-severity bugs, with an independent human audit planned before mainnet.

Built for everyone

Grandma-friendly: simple enough for anyone to hold, send, and stake.

Ethwei welcomes only real, fully USD-backed stablecoins — no algorithmic or synthetic assets.

Live on testnet with a multi-validator network (CyphCube-1 + CyphCube-2), a public block explorer, and Keplr wallet support (chain-id ethwei-testnet-1). Mainnet in preparation.

Delegate to CyphCube-2, currently 5% commission — or run your own validator.
