Transactions

The eav20 protocol has 58 transaction types, and the list is closed on purpose: a node that accepts a type it cannot execute diverges from state.

Anatomy

The signed envelope

This is the object POST /tx takes. Fields above the blank line go into the signed payload; the ones below are the result of signing.

protocol · scheme: Scheme constants. Any divergence is an immediate rejection.
amount · fee: Unsigned decimals in e7, as text — real balances exceed 2⁶⁴.
nonce: Per-account sequence. Use the API's nextNonce, which already counts the mempool.
data: Free payload per transaction type. No floating point: fractions travel as text.
signature · pqSignature: Hybrid signature: classic secp256k1 plus post-quantum ML-DSA-44.
id: Hash of the signing payload. The id you see in the explorer.

Cost

How a transaction is charged

EAV7 does not auction block space. Cost comes from a per-account resource model — energy and bandwidth — and the fee field only bounds how much of it you authorize burning.

fee is a burn limit

The effective burn is computed by the state machine from the energy and bandwidth consumed. It is not paid to the block producer: it leaves circulation.

Height-gated activation

Consensus changes are gated by fork height (CHAIN.FORK_HEIGHTS). On a network brought up with EAV7_GENESIS_ACTIVE=1, every type is active from block 0.
