urma-chain

Chain observations and transaction validation for URMA readers.

crates.io · API reference · Source · URMA

Use urma-chain to describe where a transaction was observed, decode transaction data and apply chain-specific validation. It provides the chain vocabulary used by publication and indexing components.

Get started

cargo add urma-chain

API guide

Entry point	Use it for
`observation`	Chain identities, block references, placement and observation trust.
`transaction`	Bounded transaction decoding.
`decode`	Decoding URMA records from transaction envelopes.
`validation`	Chain and proof-of-work validation helpers.

Where it fits

Connect these types to a transport through urma-runtime, or use them when building a reader for urma-wire. See the Chain API for supported networks.

Boundaries

An observation records its trust source. A provider claim and an observation from a validating node are not interchangeable, and a transaction in a mempool is not a confirmed inclusion.
