Aeva
Aeva is a layer-1 blockchain where ownership is the protocol primitive. The state machine does not model generic tokens and contract storage; it models assets, whose rights — economic, income, vote, redemption, control — are conserved units held by accounts. A “share” is one unit of every bundled right kind; splitting a share means transferring a subset of its kinds; merging is a view, not a transaction.
Everything else is built on that model and checked by the chain itself:
- Conservation. For every asset and right kind, the units held by all accounts add up to the supply. Only the issuer changes supply.
- Policies. Who may hold a right is a policy the issuer writes (open, an allowlist, a credential, a holder cap, and combinations). The chain evaluates it on the state after every issue or transfer.
- Credentials. Eligibility is proven with typed, expiring, revocable attestations that carry no personal data.
- Settlement. Delivery versus payment is native: both legs of a trade move in one transaction or not at all.
- Encumbrances and income. Pledges, liens and lockups lock units without moving them; income is paid pro rata and claimed when the holder wants.
- An EVM facade. Every right kind and every asset’s bundle is also an ERC-20 at a derived address (AE-20), so an Ethereum wallet can hold and move them — under the same policies.
Aeva is built on the Cosmos SDK (v0.54) with CometBFT consensus and Cosmos EVM.
Testnet-0
Testnet-0 is the first public network: chain id aeva-testnet-1, running
since 2026-09-22 08:31 UTC with four validators operated by the Aeva team.

What is live
- The chain with every module described in Concepts: assets and rights, policies and credentials, settlement, encumbrances, income and delegation, waterfalls and redemption pools, splits, the fee module, and the EVM facade with AE-20.
- Public endpoints for CometBFT RPC, REST, gRPC and EVM JSON-RPC.
- The indexer and the explorer . The indexer reconciles its tables against the chain every block and publishes the result on the explorer’s Integrity page.
- A faucet that hands out test AEVA and aeUSD with a
testnet.verifiedcredential. - Released, checksummed binaries for Linux (amd64 and arm64).
What is not live
- The bridge. The bridge module is in the binary, but no routes are configured on testnet-0; the Robinhood Chain testnet deployment is pending.
- Hardware wallets. Ledger signing is not supported (see Wallets).
- Open validator set. The four genesis validators are run by the Aeva team. Anyone can join as a full node, and a validator can be created with test tokens (Become a validator), but the network is not decentralised.
- Features not built, listed in the specification: partial fills and order books, snapshot-based distributions, reverse splits, a voting module (vote delegations are recorded only), IBC.
Test tokens have no value. AEVA and aeUSD on testnet-0 cannot be bought, sold or redeemed, and the network may be reset. Do not send real assets to any testnet address.
Where to go next
- Five minutes: Getting started — add the network, get test funds, make a transfer and see it on the explorer.
- Build: the Quickstart (CLI), then the Guides and the Reference.
- Operate: Run a node and Become a validator.
